There is no "Chapter" character in various editions.
The convergence of entering and exiting (the point where Qi of Yin and Yang meridians intersect), from *Jia Yi Jing*. The character "He" (convergence/meeting) is written as "Hui" (meeting) in some versions. Ma Shi says: It refers to either Yang Qi entering Yin meridians from Yang meridians, or Yin Qi entering Yang meridians from Yin meridians.
The Sun has twelve double-hours (omission of intermediate text), Yin governs the night. Zhang Jingyue says: The twelve Chen (double-hours) are the same as the Twelve Earthly Branches. In months, they are called Jian; in days, they are called Shi (time). Fixed celestial phenomena are called Jing (longitude/meridian).
Moving phenomena are called Wei (latitude/parallel). Zi (Rat) and Wu (Horse) correspond to the North and South Poles, residing in their positions without moving, thus called Jing. Mao (Rabbit) and You (Rooster) constantly rise in the east and set in the west, with constellations rotating endlessly, thus called Wei. The sky is divided into four directions.
Called East, West, South, and North. Each direction has seven mansions (lunar lodges), such as Jiao, Kang, Di, Fang, Xin, Wei, Ji; these are the Seven Mansions of the East. Dou, Niu, Nu, Xu, Wei, Shi, Bi; these are the Seven Mansions of the North.
Kui, Lou, Wei, Mao, Bi, Zui, Shen; these are the Seven Mansions of the West. Jing, Gui, Liu, Xing, Zhang, Yi, Zhen; these are the Seven Mansions of the South. These constitute the Four-Sevens Twenty-Eight Mansions. The Fang mansion is located within the Mao position, and the Mao mansion is located within the You position, thus
belonging to Wei. The Xu mansion is located within the Zi position, and the Zhang mansion is located within the Wu position, thus belonging to Jing. From the Fang mansion to the Bi mansion, their positions are in Mao, Chen, Si, Wu, Wei, Shen, thus belonging to Yang and governing the day. From the Mao mansion to the Wei mansion, their positions are in You,
Xu, Hai, Zi, Chou, Yin, thus belonging to Yin and governing the night.
Therefore, the circulation of Wei Qi (Defensive Qi) (omission of intermediate text) completes a cycle over five years. *Jia Yi Jing* writes "Sui" (year) as "Zang" (organ). Zhang Jingyue says: The circulation of Wei Qi in the body takes one day and one night, completing fifty cycles in total. Heaven's
Yang governs the day, Yin governs the night. Human Yang governs the Fu organs, Yin governs the Zang organs. Therefore, Wei Qi circulates in the Yang aspect twenty-five times during the day, and twenty-five times in the Yin aspect during the night. The Yang aspect refers to the exterior and the Fu organs; the Yin aspect refers to the interior and the Zang organs. Thus, at night it cycles through the Five Zang organs. Here, "Sui" should mean "Zang". This is an error. Zhang Zhicong also corrected it to "Zang".
Thus, at dawn when Yin is exhausted (omission of intermediate text) until the tip of the little toe, *Jia Yi Jing* writes "Yin Qi is exhausted". Various editions have Foot Taiyin, while some write Foot Taiyang. This version is erroneous and should be corrected. Zhang Jingyue says: The
following text discusses Wei Qi circulating in the Yang aspect during the day. It begins in the Foot Taiyang Bladder Meridian, circles the Six Fu organs, and reaches the Kidney Meridian, constituting one cycle. The Foot Taiyang Meridian begins at the Jingming (BL1) acupoint, so it emerges from the eyes. However, the eyes are the gathering place of numerous meridians. All the essence and Yang Qi of the Five Zang and Six Fu organs ascend to the eyes to form vision. Therefore, when Yin is exhausted at dawn,
Yang Qi reaches the eyes, causing them to open. When the eyes open, Wei Qi departs from the Jingming acupoint, ascends to the head along the neck, descends along the Foot Taiyang Bladder Meridian field, runs down along the back, and finally reaches the Zhiyin (BL66) acupoint at the tip of the little toe.
Its dispersed portion (omission of intermediate text) descends to the lateral side between the little fingers. *Jia Yi Jing* lacks the characters "Rui" and "Jian". Hand Taiyin, in various editions, is mostly written as Hand Taiyang, which should be corrected. Zhang Jingyue says: Dispersed movement refers to the freely circulating Wei Qi. The movement of Wei Qi does not follow the sequential transmission of meridians. Therefore, it starts from the medial canthus and descends to the Foot Taiyang Meridian. Its dispersed portion travels from the lateral canthus to the Hand Taiyang Small Intestine Meridian. It descends
to the lateral side between the little fingers, which is the Shaoze (SI1) acupoint.
Its dispersed portion (omission of intermediate text) pours into the space between the little finger and the ring finger. Zhang Jingyue says: This is from the Foot Taiyang Gallbladder Meridian to the Foot Shaoyang Triple Energizer Meridian and Hand Shaoyang Triple Energizer Meridian. The lateral canthus is the Tongziliao (GB1) acupoint of the Foot Shaoyang Gallbladder Meridian. Between the little toe and the second toe is the Xiaoyin (GB44) acupoint.
Above, along the lateral side of the Hand Shaoyang Triple Energizer Meridian (omission of intermediate text) enters between the five fingers. *Jia Yi Jing* has the character "Foot" above "Five Fingers". Lou Quanshan says: The characters "Fen Ce" (branch side) are superfluous. There should be
the three characters "Qi San Zhe" (its dispersed portion) below.
Zhang Jingyue says: "Fen Ce" should be read as "Wai Ce" (lateral side). Below "Little Finger", there should be the characters "Ci Zhi" (second finger), referring to the Guanchong (TE1) acupoint of the Hand Shaoyang Triple Energizer Meridian. The divergent branch ascending to the ear is this path from the Shaoyang Meridian to the Hand Yangming Large Intestine Meridian and Foot Yangming Stomach Meridian.
It converges at the pulse of the jaw, referring to descending from the fields of Chengqi (ST1) and Jiache (ST6) to pour into the Foot Yangming Stomach Meridian. "Five Fingers" should be read as "Middle Finger", referring to the Luidui (ST45) acupoint.
Its dispersed portion (omission of intermediate text) thus constitutes one cycle. *Jia Yi Jing* lacks the character "Xia" (down) after "Ear Down". Lou Quanshan says: Descending into the Yin aspect, "Xia" should be "Shang" (up). Wang Ang says: Da Zhi (Great Thumb) should be Ci Zhi (Second Finger).
Zhang Jingyue says: The collateral of the Hand Yangming Large Intestine Meridian enters the ear, so it descends along the meridian from the ear. Below "Da Zhi", there should be the characters "Ci Zhi", referring to the Shangyang (LI1) acupoint. Regarding its arrival at the foot, what is meant by "descending" is entering the sole of the foot from the Yangming Meridian, emerging from the medial malleolus, and descending into the Yin aspect via the Foot Shaoyin Kidney Meridian. The collateral of the Shaoyin Meridian is the Qiao Mai (Pivotal Vessel). The Qiao Mai belongs to the medial canthus. Therefore, it converges again at the eyes, intersecting at the Jingming (BL1) acupoint of the Foot Taiyang Bladder Meridian. This is the sequence of Wei Qi circulation during the day. From the Six Yang Meridians of the hands and feet ending at the Foot Shaoyin Kidney Meridian, this constitutes the number of one cycle. I observe: Wei Qi circulates in the Yang aspect during the day,
yet it must also traverse the Foot Shaoyin Kidney Meridian to complete one cycle. Consulting the *Xie Ke* chapter of *Ling Shu*, it also states: Wei Qi, during the day, travels in the Yang; at night, it travels in the Yin. It once traveled from the field of the Foot Shaoyin Meridian, intermittently circulating through the Five Zang and Six Fu organs. If so, why is it that regardless of day or night, it never leaves the Kidney Meridian? The root of human life lies only in Essence and Qi. Qi belongs to Yang, and Yang must be born from Yin. Essence belongs to Yin, and Yin must be born from Yang. Therefore, Ying Qi (Nutritive Qi), originally belonging to Yin, must descend from the Lung; Wei Qi, originally belonging to Yang, must ascend from the Kidney. This is the meaning of "Wei originates from the Lower Jiao". The Kidney belongs to Water, and Water is the root of Qi. Therefore, the Upper Qi Sea is at Danzhong (CV17), and the Lower Qi Sea is at Dantian. The Lung and Kidney organs of humans are thus the foundation of the growth and decline of Yin and Yang.
The Sun travels one mansion (omission of intermediate text) equivalent to 0.8 of the body length. *Jia Yi Jing* has the characters "Yu Shen" (in the body) above "One Zhou" (one cycle). Zhang Jingyue says: The following text discusses the quantity of Wei Qi circulation. The celestial sphere has twenty-eight mansions, and the Sun completes one circuit per day. The human Wei Qi completes fifty cycles in total during day and night. Taking fifty cycles as the actual number and dividing by twenty-eight, for every mansion the Sun travels, Wei Qi should complete one cycle. This corresponds to 0.785+ of the body length as the exact number. Here, saying one cycle equals 0.8 of the body length is like the celestial body traveling slightly more than one degree past the Sun, leaving a remainder.
The meaning of remainder is seen later. "She" (mansion/lodge) is the same as "Xiu" (mansion). According to Sima Qian's *Records of the Grand Historian: Treatise on Music* and *Treatise on Astronomy*, etc., the Twenty-Eight Mansions are referred to as Twenty-Eight Lodges. They are called "Lodges" because they are places where the Seven Governors (Sun, Moon, and five planets) rest.
The Sun travels two mansions. Zhang Jingyue says: When the Sun travels two mansions, human Qi should circulate three times in the body. This corresponds to 0.571+ of the body length as the exact number. Saying 0.6 implies there is a remainder. The following texts follow this pattern.
The Sun travels three mansions. Zhang Jingyue says: Human Qi should circulate five times. This corresponds to 0.357+ of the body length as the exact number. The remainder is the fractional part.
The Sun travels four mansions. Zhang Jingyue says: Human Qi should circulate seven times. This corresponds to 0.142+ of the body length as the exact number. The remainder is the fractional part.
The Sun travels five mansions. Zhang Jingyue says: Human Qi should circulate eight times. This corresponds to 0.928 of the body length as the exact number. The remainder is the fractional part.
The Sun travels six mansions. Zhang Jingyue says: Human Qi should circulate ten times. This corresponds to 0.714+ of the body length as the exact number. The remainder is the fractional part.
The Sun travels seven mansions. Lou Quanshan says: The characters "Zai Shen" (in the body) are superfluous. Zhang Jingyue says: Human Qi should circulate twelve times. This corresponds to 0.49+ of the body length as the exact number. The remainder is the fractional part. This is the number of the seven mansions in the northern region. Brief note: The characters "Zai Shen" appear in all editions. However, analyzing the context before and after, they must be superfluous.
The Sun travels fourteen mansions (omission of intermediate text) Yin receives Qi. Zhang's edition annotates "0.4 of body length" as "2". The annotation says: The Sun travels seven mansions for half a day. Traveling fourteen mansions means going from Fang to Bi constitutes one day. Human Qi should circulate twenty-five times as the exact number. Now, whenever the Sun travels one mansion, human Qi circulates once, compared to 0.8 of the body length, each mansion should leave a remainder of 0.014+ as the fractional part. Calculating over fourteen mansions, the total remainder is 0.2 of the body length, which is the fractional part for one day. When the day ends, Yang is exhausted. When Yang is exhausted, Yin receives Qi and night begins. Brief note: Ma Shi subdivides and explains the number of mansions the Sun travels. However, Zhang's annotations seem clear and comprehensive, so we retain them tentatively.
Constitutes one cycle. *Jia Yi Jing* has the character "One" above "Zhou" (cycle). Zhang Jingyue says: This describes Wei Qi circulating in the Yin aspect at night in the order of mutual overcoming (generation/control cycle). Thus, Kidney, Heart, Lung, Liver, Spleen transmit sequentially to form one cycle, and then
pour back into the Kidney.
Circulating in the Yin Zang organs. *Jia Yi Jing* writes "Yin Zang" as the character "Shen" (body). Annotation One says "Yin Zang". Ma Shi says: Yin Zang refers to all Yin meridians.
Converging again at the eyes. Zhang Jingyue says: After Wei Qi circulates in the Yin aspect for twenty-five cycles, the night ends.
When the night ends, Yin is exhausted. When Yin is exhausted, human Qi re-emerges from the Jingming (BL1) acupoint of the eyes and circulates in the Yang aspect. This is the measure of fifty cycles throughout day and night.
Yin and Yang within one day and night (omission of intermediate text) because the fractional parts are not fully exhausted. *Jia Yi Jing* writes "He You" (total has) as "She Yu" (rest in). "Ten parts of Zang Two" is written as "Ten parts of Zang Four". Note: "One" is written as "Two". The previous text mentions "Ten parts of Zang Eight", here it says "Ten parts of Zang Four", suspecting an error. Brief note: In the previous text, regarding Yang circulation, it says "0.4 of body length". (Zhang Jingyue changed it to "2" probably based on "0.2 of Zang"? However, interpreting "0.4 of body length" literally seems questionable.) Inferring from this, Yang and Yin meridians should have no discrepancy. *Jia Yi Jing* writing "Four" seems correct. Zhang Jingyue says: Previously, it was said that the Sun travels fourteen mansions, and human Qi circulates twenty-five times for half a day. The total remainder obtained is 0.2 of the body length. Therefore, in this full day and night, the Sun travels twenty-eight mansions, and human Qi circulates fifty times. The combined remainder is 0.4 of the body length in the body, and 0.2 in the Zang organs. The so-called "remainder" means that Qi has excess that is not fully accounted for. Hence, people's waking and sleeping times vary. Lou Quanshan says: The right text discusses the circulation of Wei Qi: circulating in Yang during the day causes the eyes to open and wakefulness; circulating in Yin at night causes the eyes to close and sleep. Carefully examining: This section discusses the emergence of Yang Qi at dawn from the eyes and its descent into the Three Yang Meridians of the hands and feet. They all pour in simultaneously along different paths, without any prior or subsequent sequence. At the end of this chapter, it says: At the first water drop, human Qi is in the Taiyang Meridian; at the second water drop, human Qi is in the Shaoyang Meridian; at the third water drop, human Qi is in the Yangming Meridian; at the fourth water drop, human Qi is in the Yin aspect. This implies descending first through Taiyang completely, then Shaoyang, waiting for Shaoyang to complete, then Yangming, waiting for Yangming to complete, before ascending into the Yin aspect. This contradicts this section. It is likely superfluous text.
Not according to a fixed schedule. *Jia Yi Jing* writes "Wu Yi Qi" (no endlessness/limit), which is correct.
Time has variations in length. Ma Shi says: After the Spring Equinox, days become longer; after the Autumn Equinox, days become shorter.
Using dawn as the standard. Zhang Jingyue says: This is the time when Yin and Yang intersect.
One hundred water drops (clock hours). *Jia Yi Jing* has the character "Lou" (clepsydra/water clock) above "Shui" (water), and lacks the character "Xia" (below).
If the disease is in the Three Yang Meridians (omission of intermediate text) needle when in the Yin aspect. *Jia Yi Jing* writes: If the disease is in the Yang aspect, one must first wait for the Qi to add to the Yang aspect before needling. If the disease is in the Yin aspect,
one must first wait for the Qi to add to the Yin aspect before needling.
At the first water drop (omission of intermediate text) in the Yin aspect. Zhang Jingyue says: This starts from dawn. Taiyang, Shaoyang, and Yangming are discussed including both hand and foot meridians. The Yin aspect refers solely to the Foot Shaoyin Kidney Meridian. This
is one cycle of Wei Qi circulating in the Yang aspect.
At the fifth water drop (omission of intermediate text) to the eighth water drop. Zhang Jingyue says: This is Wei Qi circulating in the Yang aspect for two cycles.
At the ninth water drop (omission of intermediate text) to the twelfth water drop. Zhang Jingyue says: This is Wei Qi circulating in the Yang aspect for three cycles.
At the thirteenth water drop (omission of intermediate text) to the sixteenth water drop. Zhang Jingyue says: This is Wei Qi circulating in the Yang aspect for four cycles.
At the seventeenth water drop (omission of intermediate text) to the twentieth water drop. Zhang Jingyue says: This is Wei Qi circulating in the Yang aspect for five cycles.
At the twenty-first water drop (omission of intermediate text) to the twenty-fourth water drop. Zhang Jingyue says: This is Wei Qi circulating in the Yang aspect for six cycles.
At the twenty-fifth water drop (omission of intermediate text) this is the measure of half a day. *Jia Yi Jing* writes "This is the measure of less than half a day". Zhang Jingyue says: At the twenty-fifth water drop, counting the previous numbers, it totals six cycles in the body. Plus the Foot Taiyang and Hand Taiyang meridians. This corresponds to the Sun traveling seven mansions, which is the measure of half a day. Note: The previous twenty-five drops account for one-quarter of the solar day. However, Wei Qi circulates only six cycles plus a fraction. Yet, totaling the solar day, it is only twenty-five cycles in the body, which does not match the meaning of fifty cycles. I suppose that at the first water drop, human Qi being in Taiyang involves two cycles. Or perhaps treating one drop as half a drop would perfectly match the total number. There may be another interpretation herein, which future scholars should correct.
From Fang to Bi (omission of intermediate text) the Sun travels half a degree. Various editions write "Fourteen Mansions", which is correct. Should be corrected. *Jia Yi Jing* writes "From Fang to Bi fourteen degrees. Fifty water drops. Measure of half a day. From Mao to Xin also fourteen degrees. Fifty water drops. Measure of a full day." Zhang Jingyue says: Fourteen mansions from Fang to Bi are Yang, governing the measure of one day. Fifty water drops. Fourteen mansions from Mao to Xin are Yin, governing the measure of one night. Also fifty water drops. Day and night total one hundred water drops. The Sun travels one degree less than the celestial sphere in total. Therefore, in this half-day of fifty drops,
the Sun travels half a degree in the heavens.
Returning to travel one mansion (omission of intermediate text) four-sevenths of a drop. *Jia Yi Jing* writes "Ri" (Sun) for "Hui" (return), and "Shi" (ten) for "Qi" (seven). Note: *Su Wen* writes "Seven". Zhang Jingyue says: This states that if the Sun returns to travel one mansion, the water clock should drop three drops and four-sevenths of a drop. If dividing one hundred drops by twenty-eight, each mansion should yield three drops and 0.5714+ of a tenth-drop. This also matches exactly with four-sevenths of a drop, with no difference in hair-breadths. This section roughly states the total number of the Twenty-Eight Mansions, so it does not distinguish between the varying degrees of the mansions.
The General Principle says (omission of intermediate text) Heaven and Earth share the same chronology. *Jia Yi Jing* lacks the character "Yue" (says). Below "Ye" (also) are the characters "Ze Zhi Er" (then know two). "Xing San Yang Xing Shang" (travel Three Yang travel up), the character "Xing" (travel) is written as "Zai" (at/in). Lacks "Xia Xing" (descend travel). "Tian Yu Di" (Heaven and Earth) is written as "Yu Tian Di" (with Heaven and Earth). Ma Shi says: The character "Zhi" (of) is superfluous. The General Principle says: The Sun adds upon the guest mansion. Zhang Jingyue says: By adding the number of the Sun's travel onto the mansion degrees, both the movement of Heaven and the movement of human Qi can be known. This summarizes the above text, stating that humans and Heaven and Earth share the same chronology.
Chaotic and disordered (symbol garbled, original meaning: Qi appears chaotic but has order). Shi Song says: According to *Tai Su Yin Yi*, the character "HT" is pronounced Pu Ba Qie. *Zi Hui*: The character "HT" is pronounced Pa. Citing this classic, Ma Shi says: Fen Fen Ran, HT HT
Ran. Although Qi seems chaotic, it has order. Zhang Jingyue says: Meaning that amidst confusion and complexity, the条理 (order/logic) remains undisturbed. Thus, it ends and begins again, cycling day and night, without end.
