《儒門崇理折衷堪輿完孝錄》Vol. 2

Discussions of feng shui (geomancy) invariably focus on two main aspects: observing landforms and selecting auspicious dates. Yet some charlatans disregard actual topography entirely, instead bewildering people with obscure terms like "sealing principles" or "celestial star qi theory" from astrological geomancy. Having thoroughly addressed these matters earlier, we shall now concentrate solely on orthodox theories of landform energy patterns.

When it comes to selecting auspicious dates, the absurd claims multiply exponentially. We encounter countless dubious methods like the "Various Schools Date Selection," "Thunderbolt Date Selection," or "Qimen Dunjia Date Selection." These heterodox theories originated from Lü Cai's Tang dynasty compilation Tongshu, which distorted yin-yang and Five Phases theory beyond recognition. Later generations of charlatans perpetuated these errors until, by the Ming dynasty's Zhengde and Jiajing eras, such superstitious nonsense reached epidemic proportions. Today the market overflows with spurious texts that deceive not only commoners but even some educated individuals. Far from attracting blessings, these practices often invite calamity.

Occasional instances where so-called "filial perfection" rituals appear effective actually stem from ancestral virtue and hidden good deeds, not these dubious methods. As the Tang dynasty geomancy master Yang Yunsong declared, "Only those who comprehend the Five Phases' inversion method attain the Great Daoist Immortal state"—a level only Yang himself achieved. Those mechanically applying these theories without Yang's mastery pervert generation into destruction, conflict into harmony, completely violating heaven-earth principles. Who would dare employ such reckless methods?

Thus we see most esoteric claims prove illusory. Even profound systems like Qimen Dunjia remain truly understood by few. Only the "Seven Administrators" theory (tracking sun, moon and five planets) maintains unbroken transmission from legendary calendar-maker Rong Cheng through Emperor Yao's celestial observations to Emperor Shun's jade astrolabe measurements. Though subtle, these cosmic patterns manifest clearly as heaven-earth's fundamental order. Why abandon this正道 (orthodox path) for superstition?

In truth, the "Five Circuits and Six Qi" of Chinese medicine simply express yin-yang and Five Phases transformations, while the "Five Planets and Seven Luminaries" physically manifest these principles. Their cyclical changes continuously influence human fortune, just as their celestial movements constantly reveal cosmic auspiciousness.

When selecting auspicious dates for feng shui, two key principles must be observed: first, analyzing the generative and restrictive relationships in the earth's Qi flow (dragon vein energy movement), and second, determining architectural orientations based on celestial configurations. Both have precise astrological foundations, but remember that Qi flows differently between morning and evening, just as celestial phenomena vary between dawn and dusk. Only through professional Qizheng almanacs (ancient astronomical calendars) can one accurately calculate and master the principles of celestial movement to obtain true date-selection secrets.

Popular simplified almanacs like perpetual calendars or palm calculation methods are unreliable—even minor errors can lead to serious consequences. Regarding feng shui taboos, simply avoid the three Sha (three inauspicious directions) and the dominant positions of Taisui (annual malefic star); other minor prohibitions need not be overemphasized.

Chapter 31 specifically explains the principles of date selection. The Yijing states that the earth nurtures all things by following celestial timing. During spring and summer—seasons of growth—earthly Qi expands outward; during autumn and winter—seasons of storage—it contracts inward. Dragon veins, acupoints, and Sha-water (feng shui terms for terrain features) represent the flow of vital energy on earth, while years, months, days, and hours reflect celestial Qi transformations. Considering geography without accounting for heavenly timing would be as futile as forcing growth in autumn or storage in spring. Thus, geographical surveys must incorporate celestial observations to fully grasp the harmony of Yin-Yang.

However, feng shui configurations shouldn't be applied rigidly—they require flexible adaptation to specific environments. Fixed patterns from ancient texts shouldn't be followed dogmatically. Some cite Mencius' saying "celestial timing is less important than geographical advantage," yet ancient burial customs (emperors interred after seven months, lords after five, etc.) demonstrate celestial timing's significance. The key lies in adapting to local conditions: while following fundamental principles, one must skillfully apply methods of reinforcement or reduction according to the waxing and waning of mountain-river Qi flows.

This scripture primarily discusses the selection of auspicious dates for funerals, emphasizing the need to harmonize both celestial timing (天时) and earthly advantages (地利). In ancient times, the Son of Heaven would be buried after seven months to await the arrival of feudal lords; feudal lords after five months for allied states to gather; high-ranking officials after three months for colleagues to assemble; and scholars after one month for relatives to convene. While these were ritual prescriptions, the actual burial still required choosing between auspicious and inauspicious days. Relying solely on almanacs (通书) for date selection often resulted in dates favorable to the deceased but detrimental to the living—sometimes leaving families unable to find a suitable burial date for decades.

The author criticizes diviners who advocate "burying immediately upon securing favorable land" (得地即葬), accusing them of either lacking discernment or acting out of financial expediency. True wisdom recognizes that celestial timing (择日) and ritual propriety are not mutually exclusive but can be balanced. The concrete method for date selection prioritizes the Day Stem (日干) as the core, the Month Branch (月支) as the guiding principle, the Year Pillar (年柱) as the foundation, and the Hour Pillar (时柱) as the outcome—analyzing the Eight Characters (八字) configuration to make the choice. This differs from fate calculation (算命), which is predetermined by heaven, whereas date selection allows human agency.

The text concludes by stressing that human destiny begins at birth, while the moment of burial establishes a new "life origin" (命元) for the deceased. An auspicious burial time can bless the family with enduring prosperity. The tomb's orientation (坐向) is determined during site selection, the birth Eight Characters are fixed at birth, and the deceased's fate is sealed at death. Date selection mainly serves to avoid clashing hours—there's no need for excessive rigidity regarding these factors.

To truly master the method of altering destiny, one must first select an optimal astrological configuration (referring to the combination of birth date and time elements) by carefully examining the cyclical patterns of the Five Phases' (Wuxing) Qi flow while simultaneously calculating the influences of celestial bodies' positions. Only by considering both aspects can a complete destiny chart be formed.

The waxing and waning strength of the Five Phases' Qi serves as the foundation determining fortune and misfortune—this principle is of utmost importance. Equally crucial are the brightening and dimming variations of celestial bodies, which also govern pivotal moments of destiny and should never be overlooked. Therefore, one must arrange elements according to their Five Phases attributes: Wood-dominant for Wood fate, Fire-dominant for Fire fate, Earth-dominant for Earth fate, Metal-dominant for Metal fate, and Water-dominant for Water fate. The four pillars (year, month, day, hour) should harmonize according to the Dao of balance—auspicious stars should occupy substantial positions aligned with seasonal timeliness, while inauspicious stars are best positioned in void spaces or meeting empty phases. Only then can the configuration manifest its true efficacy.

If the Dragon Vein's Qi (referring to geomancy's energy channels) becomes excessively strong or deficient while celestial positions fail to meet standards, what significance remains even if wealth and nobility configurations are forcibly matched?

Regarding methods for selecting destiny configurations, one must first determine the pattern type. Common configurations include: Sun-Moon Opposition (typically around the 15th day of each month), Sun-Moon Conjunction (around new moon days), Triangulation Aspect (approximately the 10th or 20th day), Cardinal Alignment (also during full moon days), Stem-Branch Sandwich (5th/6th or 25th/26th days), and Close Proximity Aspect (2nd/3rd or 28th/29th days). Among these, configurations centered on the Sun (Taiyang) and Moon (Taiyin) represent the most superior patterns.

When a particular day matches a certain configuration, theoretically all directions become usable, though specific time periods vary. For instance, the first four marks of the Mao hour (5-7am) suit Zi-Mountain Wu-Direction (true north to true south), while the latter four marks fit Gui-Mountain Ding-Direction (northeast by east to southwest by west). As hours shift, suitable orientations rotate accordingly—all twenty-four mountain-directions (compass bearings) can be calculated this way. However, special attention must be paid to avoiding the Three Killings positions and the Year Lord's (Taisui) location.

When the Imperial Star forms special aspects with the Sun, often only the Mao hour remains usable. During new moons (1st day), solar eclipses require precaution; during full moons (15th day), lunar eclipses demand vigilance—yet impacts remain negligible outside the eclipse's peak phase. Additional configurations include auspicious aspects like Heavenly Virtue (Tiande) and Lunar Virtue (Yuede) alignments, as well as special combinations featuring Official Stars and Fortune Stars.

This passage explains the ancient geomantic method of "fate calculation" (determining destiny), which centers on using the positions of the sun and moon to identify a person's Life Palace (命宫) and Body Palace (身宫).

The text first emphasizes that while various astrological patterns (like "Fields and Wealth Illumination" or "Literary Excellence Illumination") hold significance, none are as crucial as solar-centric calculations. Yet these methods are merely tools—like a craftsman’s compass or an archer’s bowstring—their efficacy ultimately depends on the practitioner’s skill.

The method unfolds in two parts:

1. Locating the Life Palace (representing innate destiny): The sun symbolizes the father, from whom one inherits primordial Qi (气). If born around the winter solstice when the sun rises during the Chen hour (7–9 AM), counting begins from Chen and proceeds clockwise to the hour of birth; for summer solstice births with sunrise at the Yin hour (3–5 AM), counting starts from Yin; otherwise, the Mao hour (5–7 AM) serves as the baseline. The palace reached at the birth hour becomes the Life Palace.

2. Determining the Body Palace (representing acquired fortune): The moon symbolizes the mother, from whom physical form is received. Starting from the moon’s position at birth, count clockwise to the birth hour to identify the Body Palace. The moon moves slower, traversing slightly more than one palace per hour.

Notably, the moon’s visibility varies by seasonal "degrees": between the autumn equinox and next year’s spring equinox, its "morning degrees" (visible dawn phase) mainly occupy the Mao palace (16–18 degrees in Mao, 19–20 in Chen, etc.). From White Dew (白露) to Qingming (清明), different distributions apply—all requiring precise computation.

(Note: "Palaces" refer to the 12 zodiacal sectors of the ecliptic, while "degrees" subdivide each palace into 30 units. This reflects ancient Chinese astronomical coordinate systems for celestial mapping.)

This passage discusses two main topics: celestial calculations and principles of feng shui site selection.

Regarding celestial observations: The text points out that while the sun completes its daily circuit, people arbitrarily fix the Minggong (Life Palace) position at the Mao hour (5-7 AM), which is clearly unreasonable. Similarly, though the moon also completes a daily circuit—albeit twelve degrees slower than the sun—people take its current position as the Shengong (Body Palace), which likewise contradicts reality. This explains why many astrological calculations prove inaccurate and fate predictions become distorted.

Concerning feng shui site selection: It details how to determine the directional flow of dragon veins (longmai) in terrain. When choosing a site, one must observe the primary dragon vein's origin and where its terminal qi converges at the "head" (endpoint). Different scenarios require specific remedial approaches:

If the primary dragon vein comes from the south but turns westward at its terminus, the terminal qi must be remedied. If it originates eastward but turns north at the terminus, the terminal qi also requires remediation. For a north-originating vein turning eastward at the terminus, the primary dragon vein itself needs adjustment. Improper remedies may lead to household decline in mild cases, or even harm people in severe instances.

Many contemporary feng shui practitioners focus solely on the final segment of the vein's qi—a practice that may deceive temporarily but inevitably brings future misfortunes. The correct method is: when assessing the primary trend, prioritize the originating dragon vein while remaining flexible about intermediate variations; when examining the terminus, focus chiefly on the segment behind the acupoint (xue), without rigidly fixating on subsequent changes.

This passage discusses two key concepts in Feng Shui geomancy: assessing Qi (审气) and calculating stellar influences (推星).

Regarding Qi assessment, it emphasizes that Feng Shui arrangements should not rigidly adhere to fixed rules. The Five Qi (五行之气) of Metal, Wood, Water, Fire and Earth are inherently dynamic and flowing—the crucial factor lies in achieving harmonious balance. If one obtains a dragon vein (龙脉) with balanced Qi, even situations where the mountain position shows conflicting Five Phase relationships or Qi leakage become inconsequential. Conversely, encountering dragon veins with excessively strong or weak Qi fields cannot be remedied by auspicious mountain positions alone. Ancient masters advocated the principle of "riding the substantial while sitting in the void" (实乘虚坐), prioritizing the dragon vein's Qi over strict adherence to the mountain's Yin-Yang and Five Phase configurations. What matters is having auspicious stars (吉星) appear in key positions—whether in the sitting/facing direction, Three Harmonies (三合), Four Cardinal (四正) or flanking positions. For inauspicious stars, one simply needs to avoid their peak periods of influence, as their weakened states require less caution.

The stellar calculation section explains that astrological computations should follow the Qizheng calendar (七政台历), observing the corresponding positions of celestial bodies. The Sun (太阳), Moon (太阴), Imperial Star (帝星) and Grace Star (恩星) represent major auspicious influences; Command Star (令星), Function Star (用星) and Fortune Star (福星) are secondary benefic bodies. Virtue stars like Year Virtue (岁德), Heaven Virtue (天德) and Month Virtue (月德), along with Nobleman (贵人), Travel Horse (驿马) and Wealth Palace (田财宫) stars all enhance good fortune. Their appearance in critical positions—mountain seats, facing directions, Three Harmonies or Four Cardinal points—signifies favorable omens. Conversely, hostile stars like Adversary Star (仇星), Calamity Star (难星), Three Killings (三煞) and Grand Duke Jupiter (太岁) must be avoided, particularly during their potent phases when their malefic effects intensify, though weakened states pose lesser threats. Selecting auspicious configurations while avoiding harmful ones forms the core principle of Feng Shui, with celestial omens manifesting through the Qizheng stars' movements.

The concluding section elucidates cosmic generation principles: Taiji (太极) differentiates into Yin-Yang, which generates the Five Phases (五行), whose transformations produce all phenomena—this constitutes the universe's eternal pattern. In heaven, this appears as the orderly movements of sun, moon, stars and Five Phases; on earth as mountain-river systems and Five Qi flows; in humans as balanced character virtues and the Five Relationships (五伦) between ruler-subject, father-son, husband-wife, elder-younger siblings, and friends.

This scripture explains how ancient sages revealed the mysteries of heaven-earth Yin-Yang and the Five Phases through the Hetu (River Chart) and Luoshu (Luo Writing)—two mystical numerical diagrams—to guide people in pursuing auspiciousness and avoiding misfortune. In the Hetu, the number fifty occupies the center, while in the Luoshu, the number five resides at the core, both symbolizing the Taiji (Supreme Ultimate), the primordial origin of the cosmos. Each diagram contains twenty odd and twenty even numbers, representing the balance of Yin and Yang.

Specifically, the Hetu arranges numbers as follows: one and six in the north correspond to Water; two and seven in the south correspond to Fire; three and eight in the east correspond to Wood; four and nine in the west correspond to Metal; and five and ten in the center correspond to Earth, with Earth Qi also distributed across the four corners. Though the Luoshu differs in numerical placement, its generative numbers correspond to those of the Hetu.

From the era of the Three Sovereigns and Five Emperors to successive dynasties, rulers established calendars and defined seasons based on these principles. Astronomers used them to calculate celestial phenomena, physicians studied the body's Qi and blood, astrologers predicted human destiny, and geomancy (Kanyu) aligned with heavenly timing to benefit the people. However, later deviations, such as Lü Cai's "Hongfan Five Phases" theory—particularly the flawed notion of "pure Yin and pure Yang"—led charlatans to misguide the populace for profit, causing great harm.

In the ninth year of the Hongwu era (1376), Emperor Taizu of the Ming dynasty, Zhu Yuanzhang, banned counterfeit almanacs, ordered the destruction of spurious texts, and commissioned officials to revise and promulgate an orthodox calendar. This effort aimed to restore the correct transmission of Yin-Yang and the Five Phases, providing future generations with proper guidance for navigating fortune and misfortune. This thirty-eighth chapter primarily discusses the fundamental relationship between the two Qi (Yin and Yang) and the Five Phases (Metal, Wood, Water, Fire, Earth).

This passage explains the correspondences between the Five Phases (Wood, Fire, Earth, Metal, Water) and the Heavenly Stems and Earthly Branches (an ancient calendrical system) in classical Chinese geomancy (Feng Shui), which studies the relationship between geographical environments and human affairs. It details the distribution patterns of the Five Phases across the celestial sphere's 365.25 degrees and their alignment with the twelve Earthly Branches (Zi, Chou, Yin, Mao, etc.) in terms of direction and Yin-Yang attributes.

In the northern direction, the Hai and Zi positions belong to Water. Within this region, the segment from the first degree of the Kui constellation in the Hai palace to the seventh degree of the Wei constellation in the Zi palace is Yin Water, while the segment from the sixth degree of the Wei constellation in the Zi palace to the 22nd degree of the Dou constellation in the Chou palace is Yang Water. In the southern direction, the Si and Wu positions belong to Fire. The segment from the ninth degree of the Zhen constellation in the Si palace to the ninth degree of the Zhang constellation in the Wu palace is Yin Fire, while the segment from the eighth degree of the Zhang constellation in the Wu palace to the 27th degree of the Jing constellation in the Wei palace is Yang Fire. In the eastern direction, the Yin and Mao positions belong to Wood. The segment from the third degree of the Dou constellation in the Yin palace to the third degree of the Xin constellation in the Mao palace is Yang Wood, while the segment from the second degree of the Xin constellation in the Mao palace to the 11th degree of the Jiao constellation in the Chen palace is Yin Wood. In the western direction, the Shen and You positions belong to Metal. The segment from the eighth degree of the Jing constellation in the Shen palace to the first degree of the Bi constellation in the You palace is Yang Metal, while the segment from the initial degree of the Bi constellation in the You palace to the fourth degree of the Lou constellation in the Xu palace is Yin Metal.

The Earth phase is unique. Although it is centrally located, its energy is distributed across the four corners: 18 degrees each in the Chen and Wei palaces belong to Yang Earth, while 18 degrees each in the Chou and Wei palaces belong to Yin Earth. Across the celestial sphere, each of the Five Phases occupies approximately 72 degrees—a fixed pattern determined by natural law.

The twelve Heavenly Stems (Jia, Yi, Bing, Ding, etc.) are positioned at the boundaries between the Earthly Branches. Though they occupy space, they do not alter the Five Phases attributes of their locations. For example, the Qian position lies between Xu and Hai. The right 7.5 degrees within Xu belong to Yang Earth, while the left 7.5 degrees within Hai belong to Yin Water. The Ren position lies between Hai and Zi: the right 7.5 degrees belong to Yin Water, and the left 7.5 degrees belong to Yang Water. Other directions follow this same principle.

Finally, the text notes that the ancient sages used the Eight Trigrams (Qian, Kun, Zhen, Xun, etc.) primarily to illustrate the movement patterns of Heaven and Earth's Qi (vital energy), not to directly demarcate these degree relationships. These divisions are all based on natural laws and should not be arbitrarily altered.

This passage discusses the evolution of ancient Feng Shui compasses (Luojing) and the laws governing celestial movements. Initially, the ancients used only the twelve Earthly Branches to correspond with fixed directions in the Hetu (an ancient cosmic diagram). Later, the ten Heavenly Stems were added to form twenty-four directions, aligning with the twenty-four solar terms of the year. However, the author argues that forcibly altering the Yin-Yang and Five Phases attributes of the Earthly Branches using the Heavenly Stems and the Bagua (Eight Trigrams) is incorrect, as the Bagua were originally tools for observing celestial movements. Later generations, unaware of this principle, fabricated various erroneous theories about celestial trigrams, which, like termites, harm people by defying natural laws. Scholars, too, blindly accepted these claims without scrutiny.

Regarding the movement patterns of the sun, moon, and stars: when the sun and moon occupy the same lunar mansion, it is called "Shuo" (new moon); when they are opposite each other, it is called "Wang" (full moon). When the moon is half-lit and half-dark, it is termed "Xian" (first or last quarter), and when it is completely invisible, it is called "Hui" (dark moon). The five major planets (Venus, Jupiter, Mercury, Mars, and Saturn) disappear ("Fu") when close to the sun, slow down ("Liu") when forming a 120-degree angle with it, move swiftly ("Ji") when near the sun, and sluggishly ("Chi") when farther away. The text also lists various mutual generation and restriction relationships: the sun avoids Rahu (a lunar node), while the moon avoids Ketu (the other node); Jupiter fears the flourishing phase of Venus, and Mars fears the flourishing phase of Mercury. These restriction patterns, like how earth does not restrict water in spring or metal does not restrict wood in summer, are essential rules for observing the "Seven Luminaries" (sun, moon, and five planets).

The twenty-eight lunar mansions span 365 and a quarter degrees in the sky. Though they appear to rise and set, celestial motion is inherently constant, rotating leftward (eastward) once daily plus an additional degree. The sun, moon, and five planets each have distinct movement characteristics—fundamental astronomical knowledge one must grasp. The author emphasizes that Yin-Yang and the Five Phases embody the profound mysteries of natural cosmic operation, not something human intervention can arbitrarily alter.

This passage discusses ancient Chinese astronomical methods for calculating celestial movements. Early astronomers observed that most celestial bodies (such as comets) rotated leftward across the heavens, with only Rahu (Luohou) and Ketu (Jidu) moving rightward—a view Confucian scholars regarded as eternal truth, recorded in detail even in astronomical classics like The New Book on Revolutionizing Astronomical Phenomena.

However, calendar specialists found it impractical to calculate the movements of the sun, moon, and five planets (Mercury, Venus, Mars, Jupiter, Saturn) using the "heavens rotate leftward" theory. They instead adopted the assumption that while the celestial sphere rotated leftward, the sun, moon, and five planets moved rightward. All twenty-eight lunar mansions (xiu) were then counted sequentially from left to right, making calculations more efficient—a method that became standard in calendar-making.

For selecting auspicious timings today, the traditional theory should be followed to ensure accuracy. When calculating the seven principal stars (sun, moon, and five planets), one must progress right to left, except for Rahu and Ketu which require reverse calculation. For example:

• When the 2nd degree of the Woman constellation (Nüxiu) is in the Rat Palace (Zi), its 1st degree passes the Ox Palace (Chou)
• When the 4th degree of the Dipper constellation (Douxiu) is in the Ox Palace, its 3rd degree enters the Tiger Palace (Yin)
• When the 2nd degree of the Tail constellation (Weixiu) is in the Tiger Palace, its 1st degree moves to the Rabbit Palace (Mao)

(The text originally detailed more transitional relationships between constellations and palaces, omitted here.)

Though calculated inversely, the stars actually move progressively. The exact midnight position lies between the 7th and 6th degrees of the Emptiness constellation (Xuxiu), while high noon aligns with the 6th and 5th degrees—the meridian's midpoint marks the pivotal transition between palaces. While the degree sequences technically require adjustment, they remain unchanged to preserve methodological continuity.

This account reveals the tension between theoretical observation and practical computation in ancient astronomy, showcasing how scholars resolved contradictions through calculative adaptations. It involves specialized terminology like the twenty-eight lunar mansions (an ancient celestial zoning system) and Rahu/Ketu (occulted luminaries in traditional astronomy), serving as crucial material for studying historical calendrical science.

This passage explains the sophisticated time division methods used in ancient fengshui geomancy (the study of geographical勘察) and calendar calculations. While the traditional system uses twelve earthly branches (Zi, Chou, Yin, etc.) to mark the hours, practical applications require further subdivision by incorporating heavenly stems.

Specifically, each earthly branch hour is divided into smaller segments: for example, the period from the third ke (刻, approximately 15 minutes) of Hai hour to the second ke of Zi hour belongs to the "Ren (壬) period." The true "Zi hour" only spans from the third ke of Zi hour to the second ke of the next full ke. The third ke of Zi hour to the second ke of Chou hour then falls under the "Gui (癸) period." This cycle continues, dividing the day into twenty-four finer segments (corresponding to the twenty-four mountain directions in fengshui), each aligned with specific heavenly stems, earthly branches, and Bagua (八卦, Eight Trigrams) orientations.

This method is particularly crucial in fengshui surveying and date selection. Since the positions of celestial bodies (their 躔度, or orbital degrees) shift continuously, calculations must be precise down to the ke to accurately determine auspicious or inauspicious timings. A mistake in time division could lead to errors in the entire divination process.

The author cautions beginners that although this leftward-rotating, sequential time-splitting method may seem complex and even startling, it has been traditionally employed for centuries. In practice, one must meticulously follow each step of the calculation without the slightest carelessness.

This passage explains ancient astronomical methods for calculating timekeeping and celestial movements. The ancients divided a day into twelve two-hour periods (shichen), each further subdivided into approximately eight ke (a ke being roughly 15 minutes), with even smaller units like "initial ke" and "initial-initial ke" for precise measurements.

The specific calculation method was based on the sun's position: during the first lunar month, the sun at mao-chu third ke (around 5:45 am) would align with the zi position (true north). The subsequent yi period corresponded to the gui position, chen period to chou position, si period to gen position (northeast), and so forth. Around the winter solstice, calculations began from the chen period, while the summer solstice calculations started from the yin period. The sun, moon, and five major planets (collectively called the "seven regulators") all rotated leftward, with only the two invisible stars Ketu and Rahu moving rightward in retrograde.

Zhu Xi (Master Zhu) explained: The celestial sphere and the seven regulators all rotate leftward. The celestial sphere completes one full rotation plus one degree daily, while the sun completes exactly one full rotation daily—thus lagging behind the celestial sphere by one degree. The moon moves even slower, completing about 13 and 7/19 degrees less than the celestial sphere each day. Some mistakenly believed the moon moved faster than the sun, which was incorrect. Calendar specialists adopted the rightward rotation concept merely for computational convenience when calculating the sun and moon's movements.

Master Wu of Linchuan added: Ancient calendar specialists actually knew the seven regulators moved leftward, but because direct calculations were too complex, they used retrograde methods to correspond with celestial measurements. Later generations mistakenly thought the sun, moon and planets actually moved rightward. He suggested visualizing an imaginary celestial disc: the heavens moved fastest, passing one degree daily across this disc; Saturn (Zhenxing) moved slower, differing by 30 degrees every 28 months; Jupiter (Suixing) slower still, differing by 30 degrees every 12 months; while Mars (Yinghuo) moved at an intermediate speed.

This content primarily describes how ancient astronomers precisely measured time through celestial observations and explains their understanding of planetary motion patterns. While this knowledge was crucial for selecting auspicious dates and times, later astrologers gradually lost grasp of these underlying principles.

This passage primarily explains the observational principles of celestial motion in ancient astronomy. The celestial sphere (here referred to as "Heaven"), with its pure Yang nature, rotates leftward (west to east), completing slightly more than one full revolution (360 degrees) per day—specifically an additional 1 degree. Over a year, this accumulates to precisely 365 and 1/4 degrees, forming the celestial circumference. The planets move at varying speeds:

Saturn (Zhenxing) moves relatively slowly, lagging behind the celestial sphere by 30 degrees every 28 months. Jupiter (Suixing) is even slower, falling behind by 30 degrees in 12 months. Mars (Yinghuo) lags by 30 degrees in just two months. The Sun (here referring to the apparent motion of Earth's orbit) trails the celestial sphere by 1 degree daily; after 365 days, it realigns with the celestial sphere, completing the annual cycle.

Venus (Taibai) moves slightly slower than the Sun but occasionally accelerates, balancing its speed to synchronize with the solar cycle. Mercury (Chenxing) is slower still than Venus, yet similarly adjusts its pace through alternating speeds to maintain synchronization. The Moon (Taiyin) moves the slowest, lagging behind the celestial sphere by 12–14 degrees daily, making its apparent "retrogression" (the lag against the stellar background) most noticeable. Ancient observers often mistakenly perceived this as actual retrograde motion.

The author, Master Zhou, concludes: In terms of velocity, the celestial sphere is the fastest, followed by Saturn, Jupiter, Mars, the Sun, Venus, Mercury, with the Moon being the slowest. All these celestial bodies rotate leftward (i.e., westward to eastward). Those studying astronomical calendars must grasp this principle. This record reflects the Daoist integration of astronomical observation with Yin-Yang theory, providing a theoretical foundation for practices like date selection (zeri) and other numerological arts.

This passage discusses the ancient astronomical principles governing the movements of the sun and moon, along with methods for selecting auspicious dates, covering celestial observations and temporal calculations.

First, the patterns of solar and lunar motion: The moon travels 13 and 7/19 degrees less than the sun each day. After 29 and 499/940 days, it realigns with the sun, forming one lunar month. Twelve such conjunctions make a year totaling 354 and 348/940 days—the moon's annual cycle.

Ancient astronomers believed heaven, the sun, moon, and five planets (wuxing) all revolved counterclockwise around the earth (termed "leftward rotation"). When observing the seven celestial bodies (sun, moon, and five planets), they found calculations cumbersome using the leftward rotation model but simpler when adopting the opposite "rightward rotation" approach. Cai Yong (Eastern Han astronomer) advocated the direct leftward method to reveal the true celestial motions.

The text meticulously records monthly correlations between the sun, moon, and twenty-eight lunar mansions (ancient stellar coordinate system):

• 11th month (Zi): Sun in Dou Mansion; at dusk, Bi Mansion due south; at dawn, Zhen Mansion due south; moon in Xingji lunar lodge (one of twelve divisions)
• 12th month (Chou): Sun in Nü Mansion; at dusk, Lou Mansion due south; at dawn, Di Mansion due south; moon in Xuanxiao lodge

(Subsequent months follow this pattern, detailing solar positions, southern constellations at twilight/dawn, and lunar lodges)

Such astronomical data was essential for date selection. Chapter 43 specifically addresses observational methods: determining seasons by tracking the Big Dipper's orientation (comprising the three stars Kui, Heng, and Biao). For instance, in the first month (Jianyin), at dusk Biao points Yin-direction; at midnight Heng aligns with Yin; at dawn Kui faces Yin—a pattern repeating monthly. When the Dipper's handle points to Yin or Mao (east), dragon-related activities are favorable in the east; when oriented toward Si or Wu (south), corresponding southern activities are auspicious.

These records embody the practical wisdom integrating celestial observation with daily life, serving as crucial materials for studying ancient calendrics and divinatory culture.

This passage primarily discusses the correspondence between celestial phenomena and geographical locations in ancient feng shui (geomancy), along with the proper and prohibited practices for arranging feng shui layouts during different seasons.

First, it explains the relationship between celestial cycles and directional orientations: When the handle of the Big Dipper (北斗七星) points to Shen and You (corresponding to the seventh and eighth lunar months), it is favorable to arrange feng shui in the western direction. When it points to Hai and Zi (the tenth and eleventh lunar months), the northern direction is auspicious. When it points to Chen, Xu, Chou, and Wei (the third, sixth, ninth, and twelfth lunar months), the four intermediate directions (southeast, southwest, northwest, and northeast) are ideal. This is because the direction indicated by the Dipper's handle marks where the cosmic Qi (炁) is most vigorous. Aligning feng shui arrangements with this energetic flow yields particularly potent results, much like planting rice in spring and wheat in autumn ensures natural growth.

Next, it details the ancient system of celestial-terrestrial correspondences (星宿分野), where specific star regions were mapped to earthly territories:

1. Xuanyao (玄枵), one of the twelve celestial divisions, corresponds to the earthly branch "Zi" and was associated with the ancient state of Qi, encompassing present-day Dengzhou, Laizhou, Qingzhou, Jinan, and Dongchang in Shandong.

2. Xingji (星纪) corresponds to "Chou" and represents the Wu-Yue region, including modern Nanjing's fourteen prefectures, Zhejiang's eleven prefectures, Jiangxi's thirty prefectures, Guangdong's ten prefectures, Guangxi's Wuzhou, and Fujian's various prefectures.

3. Ximu (析木) corresponds to "Yin" and was linked to the ancient state of Yan, covering today's Hejian, Baoding, Yongping, Longqing, Xuanfu, Bao'an in Hebei, and Liaodong.

4. Dahu (大火) corresponds to "Mao" and was the territory of the Song state, now Fengxian and Peixian in Jiangsu.

5. Shouxing (寿星) corresponds to "Chen" and was the Zheng state's domain, equivalent to modern Kaifeng and Runing in Henan.

6. Chunwei (鹑尾) corresponds to "Si" and was the Chu state's region, including Nanyang in Henan, Hanzhong in Shaanxi, ten prefectures in Hubei and Hunan (collectively called Huguang), parts of Kuizhou in Sichuan, and Guilin and Nanning in Guangxi.

7. Chunhuo (鹑火) corresponds to "Wu" and was the Zhou dynasty's heartland, spanning parts of Henan and Tongren in Guizhou.

8. Chunshou (鹑首) corresponds to "Wei" and was the Qin state's territory, comprising Luoyang in Henan, Shaanxi's capital region, Xiping, Gongchang, Yansui, Ningxia, and military-civilian prefectures like Heqing in Yunnan.

9. Shishen (实沈) corresponds to "Shen" and was the Jin-Wei region, including Taiyuan, Datong, Pingyang, and Zelu in Shanxi, as well as Shunqing in Sichuan.

These celestial-terrestrial correspondences reflect the ancient concept of "cosmic resonance" (天人感应), where astronomical patterns were systematically linked to administrative regions. This framework was used in feng shui for directional selection and auspiciousness determination.

This passage discusses the astrological field division theory in ancient feng shui geomancy (kanyu), focusing on the correspondences between the Twenty-Eight Lunar Mansions (xiu) with geographical directions and the generative-destructive cycles of the Five Phases (Wuxing).

The text first outlines geographical divisions through the Five Palaces and Eight Provinces system:

• The Great Beam (Daliang) constellation corresponds to the You hour (5-7 PM), aligning with the Zhao region (modern Hebei's Zhengding, Shunde, and Guangping areas).
• The Descending Lou (Jianglou) constellation governs the Xu hour (7-9 PM), corresponding to the Lu region (present-day Yanzhou, Shandong).
• The Ju-Zi constellation rules the Hai hour (9-11 PM), associated with the Wei region (today's Daming in Hebei and Zhangde in Henan). These celestial divisions served as crucial references for selecting auspicious dates in construction and burial rituals, particularly for predicting imperial examination success and official promotions.

The detailed Five Phases attributes and auspicious/inauspicious relationships of the Twenty-Eight Mansions are then explained:

• The Wood-phase mansions (Jiao, Dou, Kui, Jing) thrive in spring with assisting energy (xiangqi) in winter. Mars transit brings fortune (en), Venus misfortune (chou), Mercury benefits (yong), Saturn obstacles (nan), while their weakened state in summer/autumn minimizes effects.
• Metal-phase mansions (Kang, Niu, Lou, Gui) peak in autumn with summer xiangqi. Mercury is en, Mars chou, Saturn yong, Jupiter nan, showing minimal winter/spring influence.
• Earth-phase mansions (Di, Nü, Wei, Liu) flourish in summer with concurrent xiangqi. Venus brings en, Jupiter chou, Mars yong, Mercury nan, having weak autumn/winter impact.
• Sun-phase mansions (Fang, Xu, Xing, Mao) favor daytime over night.
• Moon-phase mansions (Xin, Wei, Bi, Zhang) benefit nighttime over day.
• Fire-phase mansions (Wei, Shi, Zi, Ji) prosper in summer with spring xiangqi. Saturn is en, Mercury chou, Jupiter yong, Venus nan, with reduced autumn/winter effects.
• Water-phase mansions (Ji, Bi, Shen, Zhen) peak in winter with autumn xiangqi. Jupiter brings en, Saturn chou, Venus yong, Mars nan, showing minimal summer/autumn influence.

The governing principle states: Mansions in "en/yong" states or waxing phases bring fortune, while waning phases bring misfortune. Conversely, "chou/nan" aspects during peak phases spell disaster, but prove favorable during dormancy. These celestial relationships require careful evaluation in feng shui date selection practices.

This passage primarily explains the ancient astronomical understanding of the sun and moon's movements, their symbolic meanings, and how these celestial patterns influence the selection of auspicious dates (zeji).

The sun, revered as the "essence of the Great Yang" (Taiyang zhi jing), symbolizes the earthly emperor. Its path is called the ecliptic (Huangdao), with a diameter of approximately 1.5 degrees. While it appears to circle the heavens daily from east to west, its actual movement is 1 degree slower than the celestial sphere's rotation. The ecliptic intersects with the celestial equator (the projection of Earth's equator onto the celestial sphere). During the winter solstice, the ecliptic lies 24 degrees outside the celestial equator, farthest from the North Pole, with sunrise at Chen hour (7-9 AM) and sunset at Shen hour (3-5 PM), resulting in shorter days and longer nights. Conversely, at the summer solstice, the ecliptic shifts 24 degrees inside the celestial equator, with sunrise at Yin hour (3-5 AM) and sunset at Xu hour (7-9 PM), creating longer days and shorter nights. During the spring and autumn equinoxes, when the ecliptic aligns with the celestial equator, day and night are of equal length.

The moon, honored as the "essence of the Great Yin" (Taiyin zhi jing), represents the empress. Also measuring 1.5 degrees in diameter, it moves approximately 13.37 degrees slower than the celestial sphere daily, completing its cycle in 27 days. The moon's path, called the lunar orbit (Baidao), intersects with the ecliptic but never deviates more than 6 degrees from it. Ancient scholars used fire to symbolize the sun (radiating light) and water to represent the moon (reflecting light), understanding that moonlight originates from solar illumination while the unlit portion forms the moon's dark aspect (yuepo).

When the moon and sun share the same celestial longitude, this alignment is called "new moon" (shuo, the first day of the lunar month), rendering the moon invisible. On the eighth and twenty-third days, when the moon forms a 90-degree angle with the sun, it appears as a half-illuminated waxing or waning crescent. On the fifteenth day, as the sun sets in the west, the full moon rises in the east—this opposition is called "full moon" (wang). By the thirtieth day, the moon returns to its "dark phase" (hui), becoming invisible again.

The passage concludes by explaining that when solar and lunar movements align harmoniously, with their light converging at specific auspicious positions (particularly at favorable intersections of the ecliptic and lunar orbit), activities like construction or burial ceremonies are considered most propitious. This represents a classic integration of astronomical phenomena with feng shui and date selection theories.

This passage primarily discusses the correspondences between ancient astronomy/geography and human affairs regarding auspicious and inauspicious signs, along with essential principles for date selection (Zeri) and feng shui. First, it explains the patterns of solar and lunar eclipses: A solar eclipse occurs when the moon passes between the sun and the earth (on the new moon day, Shuo), blocking sunlight; a lunar eclipse happens when the earth obstructs sunlight from reaching the moon (on the full moon day, Wang). During solar or lunar eclipses, construction, groundbreaking, or burial activities should be avoided.

Next, it details the correlations between the five major planets (Wuwei, "Five Luminaries") and the Five Phases (Wuxing): Jupiter is called the Year Star (Suixing), governing spring, and is favorable for activities related to "dragon veins" (Longmai) in the east; Mars is called the Sparkling Deluder (Yinghuo), governing summer, and favors the south; Saturn is called the Stabilizing Star (Zhenxing), presiding over transitional periods between seasons, and is suitable for the four corner directions; Venus is called the Great White Star (Taibai), governing autumn, and favors the west; Mercury is called the Time Star (Chenxing), governing winter, and favors the north. When observing solar/lunar eclipses or unusual celestial phenomena, one must assess their auspicious or inauspicious implications based on their corresponding terrestrial regions (Fenye).

The concept of geographical correspondences (Fenye) is not baseless—there is indeed a tangible relationship between celestial bodies and terrestrial regions. For instance, if the Mao direction (due east) of a location features elegant mountain and water formations (Xiu Sha and Xiu Shui), it foretells that people born in the Mao year will achieve prominence or that success is likely during Mao or Yi years. Similarly, if the You direction (due west) has auspicious scenery, it indicates official advancement in the Zhao region; favorable signs in the Xu direction (northwest) correspond to the Lu region. However, it is crucial to note that such predictions are accurate only when paired with genuine noble dragon lairs (high-quality feng shui configurations) and when the Qi (vital energy) is flourishing.

Finally, the text cites Zhu Xi's perspective: In date selection, primary consideration should be given to the Emperor Stars (Dixing, celestial rulers governing astronomical phenomena). According to the Yueling (Monthly Ordinances), spring corresponds to the Great Bright Emperor (Taihao Di, the Green Emperor, ruler of Wood Virtue) and the Goumang Spirit (Wood Official); summer corresponds to the Flame Emperor (Yandi, the Red Emperor, ruler of Fire Virtue) and the Zhurong Spirit (Fire Official); late summer corresponds to the Yellow Emperor (Huangdi, ruler of Earth Virtue) and the Houtu Spirit (Earth Official). Although these Emperor Star systems are not explicitly recorded in almanacs, their foundations can be traced to the Yijing (Book of Changes) and the Liji (Book of Rites).

This passage discusses the celestial movements of the "Imperial Star" (帝星) in ancient Chinese geomancy (Feng Shui) theory, dividing the year into four seasons, each governed by specific celestial rulers and deities:

Autumn corresponds to Shaohao (the White Emperor) and Rushou (the Metal Official Deity), representing the sovereign and minister who govern white essence (Jing) and the Metal phase. Winter aligns with Zhuanxu (the Black Emperor) and Xuanming (the Water Official Deity), the rulers who preside over black essence and the Water phase.

The text then cites the Yijing (Book of Changes) to illustrate the celestial emperor's cyclical path: manifesting in the Zhen position (east), organizing in the Xun position (southeast), revealing in the Li position (south), laboring in the Kun position (southwest), rejoicing in the Dui position (west), battling in the Qian position (northwest), toiling in the Kan position (north), and completing in the Gen position (northeast). This demonstrates how the cosmic sovereign, originally one celestial emperor, differentiates into four and then eight directions to govern the universe.

A detailed breakdown follows of the celestial emperor's positions throughout the twenty-four solar terms: from Jingzhe (Awakening of Insects) to Chunfen (Spring Equinox) in Zhen (east); from Guyu (Grain Rain) to Lixia (Start of Summer) in Xun (southeast); from Mangzhong (Grain in Ear) to Xiazhi (Summer Solstice) in Li (south); from Dashu (Major Heat) to Liqiu (Start of Autumn) in Kun (southwest); from Bailu (White Dew) to Qiufen (Autumn Equinox) in Dui (west); from Shuangjiang (Frost's Descent) to Lidong (Start of Winter) in Qian (northwest); from Daxue (Major Snow) to Dongzhi (Winter Solstice) in Kan (north); and from Dahan (Major Cold) to Lichun (Start of Spring) in Gen (northeast). Through the seventy-two pentads (ancient five-day climate periods), one can calculate the celestial emperor's precise location across the 365¼ days of the year.

The text concludes that the celestial emperor's seasonal position determines auspicious timing (吉时) and favorable directions (吉方). Master Yang of Feng Shui famously taught that spring's east, summer's south, late summer's southwest, autumn's west, and winter's north bring fortune—a principle the author laments modern people disregard, foolishly rejecting classical wisdom for baseless claims.

A final query addresses the Five Phases' directional attributes: Wood (east), Fire (south), Metal (west), Water (north), and Earth (four corners). This forms the foundational theory of Five Phases (五行) orientation in geomancy.

This passage primarily explains the correspondences between celestial phenomena and terrestrial Five Phases (Wuxing). The ancients associated the twelve earthly branches (Zi, Chou, Yin, etc.) with the Five Phases (Metal, Wood, Water, Fire, Earth) and the seven luminaries (the sun, moon, and five visible planets), but emphasized these were symbolic correspondences rather than direct equivalences.

For instance, the Zi and Chou directions belong to Earth, but this doesn't mean these branches are Earth itself—rather, they represent Earth's cardinal palace positions. Similarly, Yin and Hai belong to Wood, indicating the directional path of Jupiter's movement. The Wu position is the solar palace and Wei the lunar palace, yet Wu and Wei aren't literally the sun and moon, just as Lishui produces gold and Kunlun yields jade without the locations being identical to the products.

The text elucidates this correspondence through three levels: The sun and moon suspended in heaven are most prominent, hence the sun resides in Wu position and moon in Wei position. Earth fundamentally consists of soil, hence Earth occupies Zi and Chou positions. The seasonal cycles hold supreme importance, thus Wood, Fire, Metal and Water correspond respectively to spring, summer, autumn and winter directions (Yin-Hai for spring Wood, Mao-Xu for summer Fire, etc.). A single astrological chart thus encapsulates heaven and earth's operational laws, much like Emperor Shun's ancient practice of observing the seven luminaries to establish calendars.

Finally, it clarifies that among the twenty-eight lunar mansions, those containing the character for "sun" (like Star-Sun-Horse or Void-Sun-Rat) don't indicate multiple suns in heaven, but mark the solar trajectory's directional positions—analogous to temporary palaces established during ancient emperors' inspection tours. The divisions of the twenty-eight mansions all trace the seven luminaries' paths, like modern officials' temporary lodgings during inspections. Those who truly comprehend this principle naturally grasp its profound meaning.

As Chapter 49, this section mainly analyzes questions regarding the correspondences between the five visible planets and the Five Phases system.

The ancients used an eight-foot gnomon to determine the cardinal directions, but in remote regions, the shadow's orientation differed from that of the Central Plains. Though the compass needle (Xuanzhen, or "Mysterious Needle") fluctuates, it follows discernible patterns. One cannot simplistically apply uniform standards to determine the meridian direction—each locality has its own baseline.

Consider how the ancients conceptualized "center": in a main hall, the center of that hall was deemed the "center"; in a chamber, the chamber's midpoint became its "center." Though geographical locations vary, each possesses its own central reference. Contemporary debates claiming that compass orientations in remote areas contradicting Central Plains measurements are erroneous miss this principle. By applying the theory of "Lianfu Yizi" (a feng shui term denoting specific directional combinations), we understand that the true meridian needle (Zi-Wu Zhengzhen) actually inclines slightly between the Ren and Bing positions (between Ren Mountain and Bing Mountain on the compass dial)—this being the accurate interpretation.

This constitutes the discourse on the "Central Needle" in Chapter Fifty.

Through centuries of verification, the moon (Taiyin) and sun (Taiyang) stand as the most auspicious celestial bodies in mountain-dwelling geomancy. Thus when selecting dates for construction or burial (Zeri Zaozang), both serve as primary references. All preceding discussions derive from lunar and solar orbital patterns. As for the five planets (like Venus) and the four imaginary stars (Rahu, Ketu, etc.), their calculations require precise hourly determinations and cannot be predetermined. Hence, subsequent sections detail these two luminaries' movement patterns, enabling novices to navigate fortune without annual almanacs.

Regarding the sun: Chen Xiyi (the renowned Northern Song Daoist) described it as the yang within yin, embodying sovereign authority. Its virtue (De) manifests ultimate firmness; its essence embodies supreme vigor, traversing the heavens to demarcate day from night and seasons from each other. Though the sun completes its daily celestial circuit one degree slower than fixed stars, its annual accumulation perfectly synchronizes with celestial phenomena. Solar motion follows three paths: the ecliptic (primary orbit), the northern extreme reaching Well constellation (near the North Pole), the southern extreme reaching Ox constellation (distant from the Pole), with the eastern Horn and western Lou constellations marking intermediate positions—these constitute the central, southern, and northern orbital paths.

Specifically: when the sun reaches the southernmost Ox constellation at winter solstice, daylight lasts 40 ke (ancient time units) against 60 ke of night; at the northernmost Well constellation during summer solstice, the ratio reverses to 60:40; during the equinoxes at intermediate Horn and Lou positions, day and night balance at 50 ke each.

Detailed solar celestial divisions: After the Rain Water solar term in the first month, the sun enters the Xu-Ju lunar mansion (one of the 28 constellations) in the Hai palace, corresponding to Jia, Bing, Geng, and Ren directions. Following the Spring Equinox in the second month, it progresses to the Jianglou mansion in the Xu palace, aligning with Gen, Xun, Kun, and Qian orientations. After Grain Rain in the third month, it enters the Daliang mansion in the You palace... (subsequent trajectories follow this pattern).

This passage primarily discusses the positions of the sun and moon (Taiyin) during different times of the year and their corresponding auspicious or inauspicious orientations, belonging to the astronomical calendar system within ancient Kan Yu (Feng Shui) theory.

Regarding the sun's movement: Beginning from the Grain Buds solar term in the fourth month, the sun sequentially passes through the Shen constellation (Shishen position, corresponding to Gui, Yi, Ding, Xin directions). After the Summer Solstice in the fifth month, it moves to the Wei constellation (Chunshou position, corresponding to Jia, Bing, Geng, Ren directions). Following Great Heat in the sixth month, it reaches the Wu constellation (Chunhuo position, corresponding to Gui, Yi, Ding, Xin directions). After End of Heat in the seventh month, it enters the Si constellation (Chunwei position, corresponding to Jia, Bing, Geng, Ren directions). Following the Autumn Equinox in the eighth month, it proceeds to the Chen constellation (Shouxing position, corresponding to Qian, Kun, Gen, Xun directions). After Frost's Descent in the ninth month, it arrives at the Mao constellation (Dahuo position, corresponding to Gui, Yi, Ding, Xin directions). Following Minor Snow in the tenth month, it moves to the Yin constellation (Ximu position, corresponding to Bing, Geng, Jia, Ren directions). After the Winter Solstice in the eleventh month, it enters the Chou constellation (Xingji position, corresponding to Gen, Xun, Kun, Qian directions). Finally, after Major Cold in the twelfth month, it reaches the Zi constellation (Xuanxiao position, corresponding to Yi, Ding, Xin, Gui directions). The sun's current position represents the direction illuminated by its radiance, making it suitable for Feng Shui arrangements. Special attention should be paid when encountering the Fang, Xu, Mao, and Xing constellations, as these are particularly auspicious, but solar eclipses and other celestial anomalies must be strictly avoided.

Concerning the moon's (Taiyin) movement: The moon represents yin within yang, symbolizing the empress with its gentle, compliant nature. The moon itself doesn't emit light but reflects the sun's brilliance. Starting from the moonless period between lunar months (Hui-Shuo), after traveling approximately 37 degrees over three days, the new moon (Shuo) appears, visible at dusk in the Geng direction. Eight days later, having moved about 98 degrees, the first quarter moon appears at dusk in the Ding direction. Fifteen days later, after traveling roughly 182.5 degrees, the full moon (Wang) appears at dusk in the Jia direction. Each lunar phase carries corresponding directional auspiciousness or inauspiciousness.

This passage explains the relationship between the moon's movement patterns in ancient astronomy and seasonal directional orientations. The moon completes its cycle in approximately 29.5 days, during which it undergoes various phases: beginning from its appearance in the Jia (甲) direction on the third evening of the lunar month, then developing its "dark aspect" (生魄) after traveling less than 190 degrees over three days; reaching the "last quarter moon" after covering 81 degrees when half-illuminated; and finally becoming completely invisible during its conjunction with the sun, known as "the dark moon" (晦).

The moon moves about 352 degrees, 8 minutes, and 6 seconds daily—12 and 1/19 degrees slower than the sun. A complete synodic cycle takes 29 and 499/940 days, constituting one lunar month. Twelve such months total 354 and 348/949 days, forming a lunar year.

The text mentions "nine paths" (九行) referring to the moon's orbital tracks: two black paths north of the ecliptic, two red paths south of the ecliptic, two white paths west of the ecliptic, two blue paths east of the ecliptic, plus the ecliptic itself. During different solar terms, the moon follows specific paths: the blue path in the Jia (甲) direction during Beginning of Spring and Spring Equinox; the white path in the Geng (庚) direction during Beginning of Autumn and Autumn Equinox; the black path in the Ren (壬) direction during Beginning of Winter and Winter Solstice; and the red path in the Bing (丙) direction during Beginning of Summer and Summer Solstice.

When the sun and moon conjoin at particular directions, they form auspicious orientations called "Celestial Virtue" (天德) and "Lunar Virtue" (月德). For instance, during the third month when the celestial stems align with Chen (辰), their conjunction occurs in the You (酉) direction—rising from Geng (庚) and setting at Ren (壬)—making Ren (壬) the Virtue-bearing direction. Other seasons have corresponding orientations: the sixth month in Jia (甲), the ninth in Bing (丙), and the twelfth in Geng (庚). These patterns reflect ancient cosmological thought that integrated astronomical observation with geomantic auspices.

This passage discusses ancient Chinese geomancy (Feng Shui) records concerning the movements of the sun and moon, primarily used for date selection and directional calculations.

Regarding celestial movements, it states: The Mao (east) and You (west) directions—the cardinal points of sunrise and sunset—hold particular significance due to their intimate connection with solar (Yang energy) and lunar (Yin energy) forces. When the moon (Taiyin) enters auspicious positions during its monthly transit through celestial palaces, practitioners may confidently implement Feng Shui arrangements, as even malevolent stars (Tianyao) and terrestrial sha energies (Disha) become subdued during such periods. However, lunar eclipses or celestial anomalies were considered extremely inauspicious omens.

The text provides detailed solar ephemerides recording the sun's position among lunar mansions across the twenty-four solar terms. For instance: At Winter Solstice, the sun resides at the 4th degree of the Ji constellation; Minor Cold at the 10th degree of Dou; Major Cold at the 3rd degree of Niu—with each term progressing sequentially. A concrete example illustrates this progression: should the sun occupy the 4th degree of Ji on Winter Solstice day, it advances to the 5th degree the following day, then the 6th degree thereafter, maintaining this incremental movement through each solar term.

Corresponding lunar tables document the moon's position during the first two days of each lunar month: 1st month at Zi (due north), 2nd month at Hai (north-northwest), 3rd month at Xu (northwest), etc. The text further exemplifies: During the 1st lunar month, the moon occupies Zi position on days 1-2, shifts to Hai on days 3-5, then Xu on days 6-7—a sequential pattern repeating monthly.

These astronomical records formed essential references for ancient geomancers to determine auspicious dates and orientations, interpreting fortune through observed patterns of celestial motion.

This passage primarily discusses ancient Chinese astrology concerning the observation and calculation methods for the movements of the sun, moon, and five major planets (Jupiter, Mars, etc.).

It first explains that the patterns of solar and lunar motion are fixed and unchanging. By determining their positions (celestial palaces), one can calculate the locations of the Life Palace (minggong) and Body Palace (shengong), thereby deriving the movements of the other five planets (Metal, Wood, Water, Fire, Earth) and the four auxiliary stars (Rahu, Ketu, etc.). These calculations form the essential basis for selecting auspicious times and locations, which practitioners must master first.

The text then specifically describes the characteristics of Jupiter (the Year Star): Jupiter belongs to the eastern direction and manifests a blue-green color. Its movement includes direct motion, stationary periods, and retrograde motion. Direct motion brings blessings, stationary periods (called "Long Mourning Luminary") reduce fortune and invite disasters, while retrograde motion (called "Disaster Sorrow Star") indicates major calamities. Jupiter moves approximately 1 degree every 6 days, though sometimes 1 degree in 3 or 5 days. It traverses one celestial palace per year, completing a minor cycle in 12 years and a major cycle in 82 years. Encountering Jupiter in direct motion within the eastern "Azure Dragon" quadrant allows bold selection of construction sites, as it can neutralize various malignant influences. Its most auspicious positions are among the Jiao, Dou, and Kui constellations, with Ji, Bi, Shen, and Zhen being secondary.

Next, it details the properties of Mars (the Sparkling Deluder): Mars belongs to the southern direction and embodies the essence of fire. Its motion includes varying speeds, direct movement, stationary periods, and retrograde phases. Direct motion brings fortune, stationary periods (called "Celestial Rainbow") presage fires, retrograde motion (called "Celestial Assault") heralds plagues and family ruin, while its dormant position (called "Black Heaven Luminary") indicates grave misfortune. Mars moves about 1 degree every 18 hours, traversing one palace every 50 days. When positioned in its dominant palaces, it can rapidly activate scholarly achievements and wealth, particularly enhancing literary talent.

These contents originate from Chapters 51 and 52 of The Complete Filial Record of Confucian-Adjusted Geomancy, representing the astrological theories of the Li family from Rao'an. They were primarily applied in feng shui date selection and destiny calculation.

This passage primarily discusses the movement patterns and auspicious/ominous influences of Mars, Saturn, and Venus in ancient astrological systems. The speed of Mars' movement determines different fortunes: when moving slowly (2 degrees per day), taking two months to pass through one lunar mansion, sudden misfortunes are likely; when moving swiftly (5 degrees in 7 days), passing through one mansion in 45 days indicates stability. Its complete cycle takes 79 years.

When southern dragon veins (fengshui term referring to mountain ranges) align with Mars' movement, auspiciousness occurs during specific directional combinations called "three harmonies and four cardinal positions." Mars reaches its most favorable position ("entering its temple") when passing through constellations like Tail and Chamber, while gaining power in constellations like Dipper and Horn. The general rule follows that direct motion brings fortune while retrograde motion brings misfortune.

Saturn (also called the Stabilizing Star), associated with central earth element (Wuji earth), moves even slower—taking three years to shift one mansion with a complete cycle of 59 years. Its retrograde motion earns it the name "Home-Destroying Star" that invites disasters, while direct motion brings wealth and honor. When western dragon veins align with Saturn's movement, greatest auspiciousness occurs in constellations like Root and Maiden, capable of neutralizing malignant influences.

Venus (Taibai Star) also exhibits direct and retrograde motion—direct movement brings profound blessings while retrograde weakens fortunes. Special caution is required when Venus encounters ominous stars like Yuebo (Moon's Dark Companion) or Rahu (the Shadow Star), but favorable conditions for imperial examinations arise when sharing mansions with the Sun, Moon, or Mercury. Venus moves at moderate speed—1.5 degrees per day, passing one mansion monthly.

These astrological principles were historically applied in fengshui site selection ("Qianli" refers to determining architectural orientation), believing that aligning with celestial patterns could neutralize "heavenly maleficence and earthly slaughter" (various inauspicious forces). Choosing orientations where stars "enter their temples" or "gain power" was thought to secure good fortune.

This passage discusses the movement patterns and auspicious/ominous signs of several important celestial bodies in ancient astrology, focusing particularly on Venus, Mercury, the Purple Qi Star, and the Moon's Dark Essence (Yuebo).

Regarding Venus (Taibai Star): Venus completes its celestial circuit annually, harmonizing with the degrees of other constellations. Special attention should be paid to its appearance in the eighth month, which typically brings blessings rather than calamities. When Venus illuminates the three favorable directions, or when it enters specific celestial sectors (known as "entering its palace") simultaneously with the sun, appears near the Santai stars, or shares a palace with Jupiter, these all signify great wealth and nobility. In feng shui, western dragon veins (terrain formations) blessed by Venus's radiance become ideal sites for establishing dwellings, capable of subduing various malignant influences. Venus reaches its most auspicious state ("entering its temple") when in the Kang, Niu, Lou, or Gui constellations, and achieves secondary auspiciousness ("gaining power") in the Di, Nü, Wei, or Liu constellations. Its direct motion brings good fortune while retrograde motion portends danger.

Mercury (Chenxing) exhibits these characteristics: Its celestial movements follow orderly patterns with varying speeds but rarely retrograde. This star generally presages good fortune, bringing immeasurable blessings when encountering the sun. Slower movement diminishes its potency, and its patterns alter when sharing palaces with Yuebo or Mars. Mercury often travels close to the sun like a minister attending his sovereign. It moves approximately 1.5 degrees daily, traversing one palace monthly—slower cycles take 69 days per palace, faster cycles 20 or even 17 days. Its annual path varies, completing a grand cycle roughly every 65 years. Northern dragon veins receiving Mercury's illumination may disregard other inauspicious signs when selecting sites. Mercury reaches its temple state in the Ji, Bi, Shen, or Zhen constellations, and gains power in the Kang, Niu, Lou, or Gui constellations.

The Purple Qi Star represents Jupiter's residual energy, symbolizing auspicious fortune—encountering it ensures smooth endeavors. This benevolent star becomes particularly potent when entering specific celestial sectors. Moving steadily about 1 degree monthly (12 degrees annually), it completes one palace every 3 years and finishes its 28-year celestial circuit. Southeastern dragon veins benefit most from its radiance.

The Moon's Dark Essence (Yuebo, also called Lunar Deity or Broom General) manifests from Mercury's residual energy, primarily reducing blessings and amplifying misfortunes. However, when meeting the five planets during their direct motion, it may occasionally provide assistance.

This passage elucidates the movement patterns and auspicious/ominous influences of three extraordinary celestial phenomena (Yuebo, Rahu, and Ketu) in Daoist astrology.

Yuebo (a malefic star in Daoist astrology) brings great calamities when retrograde or conjunct with other inauspicious stars. Its entry into specific celestial sectors (known as yuan and temple palaces) manifests as either fortune or misfortune depending on accompanying stars—malefic stars intensify its negative effects while auspicious stars bring good luck. Yuebo follows precise orbital patterns: moving three degrees monthly, traversing one zodiacal palace every nine months, covering forty-nine degrees in twelve months, and completing its heavenly cycle every sixty-two years. It's most favorable for locating dragon veins (feng shui term for earth Qi convergence points) in the northeast direction.

Rahu (also called Celestial Head Star) fundamentally belongs to the Water phase, exerting strongest influence when unobstructed by unfavorable stellar configurations. This perpetually retrograde star possesses a violent nature with weak benefic power. Conjunction with the Sun causes solar eclipses, while conjunction with the Moon produces lunar eclipses—both extremely inauspicious alignments. Only when positioned in its temple palace (auspicious location) conjunct with Mars does it bestow blessings. Rahu moves one degree every nineteen days, shifts one zodiacal palace every eighteen months, completes a minor cycle in nineteen years, and finishes its grand cycle in ninety-three years. It's most compatible with dragon veins of Fire and Earth attributes.

Ketu (also known as Eclipse Spirit or Leopard Tail Star) shares Rahu's nature, being predominantly ominous. This retrograde star similarly causes solar/lunar eclipses when conjunct with the Sun or Moon, bringing great misfortune. Conjunction with Mars or Saturn during direct motion may bring fortune, but encounters with retrograde Mars/Saturn invite sudden disasters. Ketu's movement mirrors Rahu's: one degree every nineteen days, one palace every eighteen months, minor cycle in nineteen years, and grand cycle in ninety-three years. It harmonizes best with dragon veins of Earth and Metal attributes.

These celestial bodies' orbital cycles and mutual influences formed crucial foundations for determining auspiciousness in ancient Daoist astrological calculations.
