12. 手掌中，中指上端确定司天（主管上半年气候的六气之一）之位，中指根部纹路确定在泉（主管下半年气候的六气之一）之位。顺着手指方向，食指的第二、第三节分别对应初之气和二之气；第四指（无名指）的头节纹对应四之气，二节纹对应五之气。司天之气位于三之气的位置，在泉之气自然位于六之气的位置。主气（每年固定不变的六步气候变化）按照木、火、土、金、水的顺序排列；客气（每年轮转变化的六步气候变化）则用阴阳一二三来命名。
【注】左手掌心向上，以中指指尖上方定出司天之位，中指根部的横纹定出在泉之位。顺次向食指延伸，食指的第三节纹定出初之气位，头节纹定出二之气位。中指指尖上方定出三之气位，即司天之位。第四指（无名指）的头节纹定出四之气位，二节纹定出五之气位。中指根部的横纹定出六之气位，即在泉之位。所谓主气以木、火、土、金、水为序，是指五行之气顺次分布的五个位置。因此，初之气是厥阴风木；二之气是少阴君火；三之气是少阳相火；四之气是太阴湿土；五之气是阳明燥金；六之气是太阳寒水。这是木生火、火生土、土生金、金生水、水生木的相生次序，固定不变。所谓客气以一二三来命名，是指三阴三阳六气的加临。因此，厥阴为一阴，少阴为二阴，太阴为三阴，少阳为一阳，阳明为二阳，太阳为三阳。这是一生二、二生三、三复生一，阴极生阳、阳极生阴，六步升降的顺序每年依次排取。以此定位，主气和客气便了然于掌中了（图十七）。
13. 天符（岁运与司天之气相同）是中运与天气相同，岁会（岁运与地支五行属性相同）是本运临本支之位。四方正位和四维方位都是岁会，太乙天符（岁运、司天、地支三者相同）则是符会俱同。同天符（岁运与在泉之气相同且为阳年）与同岁会（岁运与在泉之气相同且为阴年），在泉之气与中运之气相同即为同司天或同在泉。阴年称为同岁会，阳年称为同天符可知。
【注】天符，是指中运（统管全年气候的五行之气）与司天之气属于同一类气。例如：木运遇木司天，如丁巳年、丁亥年；火运遇火司天，如戊子年、戊午年、戊寅年、戊申年；土运遇土司天，如己丑年、己未年；金运遇金司天，如乙卯年、乙酉年；水运遇水司天，如丙辰年、丙戌年，共十二年。岁会，是指本运临于本支（地支五行属性与本运相同）的位置。例如：木运临卯（卯属木），是丁卯年；火运临午（午属火），是戊午年；金运临酉（酉属金），是乙酉年；水运临子（子属水），是丙子年，这称为四正。土运临四季（辰、戌、丑、未均属土），是甲辰年、甲戌年、己丑年、己未年，这称为四维，共八年。太乙天符，是指既是天符之年，又是岁会之年，即天气（司天）、运气（中运）、岁支（地支）三者汇聚。例如：己丑年、己未年，中运为土，与司天土同气，且土运临丑未（丑未属土）；乙酉年，中运为金，与司天金同气，且金运临酉；戊午年，中运为火，与司天火同气，且火运临午，共四年。同天符、同岁会，是指在泉之气与中运之气属于同一类气。阳年称为同天符，如木运遇木在泉，如壬寅年、壬申年；土运遇土在泉，如甲辰年、甲戌年；金运遇金在泉，如庚子年、庚午年。阴年称为同岁会，如水运遇水在泉，如辛丑年、辛未年；火运遇火在泉，如癸卯年、癸酉年、癸巳年、癸亥年，共十二年。这些气运符会的不同之处，人不可不知。上天符十二年，太乙天符四年，岁会八年，同天符六年，同岁会六年。然而，太乙天符的四年，已经包含在天符的十二年中了。岁会的八年，也有四年包含在天符之中了。综合而言，六十年中只有二十八年符合这些特殊条件（图十八--二○）。
12. On the palm, the upper end of the middle finger determines the position of the Si Tian (Si Tian refers to one of the six Qi governing the climate of the first half of the year), and the root crease of the middle finger determines the position of the Zai Quan (Zai Quan refers to one of the six Qi governing the climate of the second half of the year). Proceeding along the fingers, the second and third segments of the index finger correspond to the First Qi and Second Qi respectively; the head segment of the fourth finger (ring finger) corresponds to the Fourth Qi, and its second segment corresponds to the Fifth Qi. The Si Tian Qi is located at the position of the Third Qi, and the Zai Quan Qi naturally occupies the position of the Sixth Qi. The Zhu Qi (Zhu Qi refers to the six steps of climate change that remain fixed annually) follows the sequence of Wood, Fire, Earth, Metal, and Water; the Ke Qi (Ke Qi refers to the six steps of climate change that rotate annually) is named using Yin-Yang and One-Two-Three.
[Annotation] With the left hand palm facing up, the area above the tip of the middle finger marks the position of Si Tian, and the transverse crease at the base of the middle finger marks the position of Zai Quan. Moving sequentially towards the index finger, the third segment crease of the index finger marks the position of the First Qi, and the head segment crease marks the position of the Second Qi. The area above the tip of the middle finger marks the position of the Third Qi, which is the position of Si Tian. The head segment crease of the fourth finger (ring finger) marks the position of the Fourth Qi, and the second segment crease marks the position of the Fifth Qi. The transverse crease at the base of the middle finger marks the position of the Sixth Qi, which is the position of Zai Quan. The term "Zhu Qi" following the order of Wood, Fire, Earth, Metal, and Water refers to the five positions where the Five Elements Qi are distributed in sequence. Therefore, the First Qi is Jue Yin Wind-Wood; the Second Qi is Shao Yin Sovereign-Fire; the Third Qi is Shao Yang Minister-Fire; the Fourth Qi is Tai Yin Damp-Earth; the Fifth Qi is Yang Ming Dry-Metal; and the Sixth Qi is Tai Yang Cold-Water. This represents the generative sequence of Wood generating Fire, Fire generating Earth, Earth generating Metal, Metal generating Water, and Water generating Wood, which is fixed and unchangeable. The term "Ke Qi" being named by One, Two, Three refers to the superposition of the Six Qi of Three Yin and Three Yang. Thus, Jue Yin is One Yin, Shao Yin is Two Yin, Tai Yin is Three Yin, Shao Yang is One Yang, Yang Ming is Two Yang, and Tai Yang is Three Yang. This reflects the principle that One generates Two, Two generates Three, and Three regenerates One; when Yin reaches its extreme, Yang is born; when Yang reaches its extreme, Yin is born. This is the sequence of ascent and descent of the six steps, arranged annually. By using this positioning method, the Zhu Qi and Ke Qi become clear within the grasp of the hand (Figure 17).
13. Tian Fu (Tian Fu refers to years where the Central Yun is identical to the Si Tian Qi) indicates that the Central Yun is identical to the Heavenly Qi. Sui Hui (Sui Hui refers to years where the Central Yun shares the same elemental attribute as the Earthly Branch) means the original Yun governs its own branch position. The four cardinal directions and four intercardinal directions are all Sui Hui, while Tai Yi Tian Fu (Tai Yi Tian Fu refers to years where Central Yun, Si Tian, and Earthly Branch are all identical) involves the convergence of these符会 (Fu Hui). Tong Tian Fu (Tong Tian Fu refers to years where the Central Yun is identical to the Zai Quan Qi in a Yang year) and Tong Sui Hui (Tong Sui Hui refers to years where the Central Yun is identical to the Zai Quan Qi in a Yin year) imply that the Zai Quan Qi is identical to the Central Yun, thus sharing the same governance. Yin years are called Tong Sui Hui, and Yang years are known as Tong Tian Fu.
[Annotation] Tian Fu refers to years where the Zhong Yun (Zhong Yun refers to the Five Elements Qi governing the climate of the entire year) and the Si Tian Qi belong to the same category of Qi. For example: Wood Yun with Wood Si Tian, such as Ding Si year and Ding Hai year; Fire Yun with Fire Si Tian, such as Wu Zi year, Wu Wu year, Wu Yin year, and Wu Shen year; Earth Yun with Earth Si Tian, such as Ji Chou year and Ji Wei year; Metal Yun with Metal Si Tian, such as Yi Mao year and Yi You year; Water Yun with Water Si Tian, such as Bing Chen year and Bing Xu year, totaling twelve years. Sui Hui refers to the situation where the original Yun governs its own branch position (where the Earthly Branch's elemental attribute matches the Yun). For example: Wood Yun governing Mao (Mao belongs to Wood) is Ding Mao year; Fire Yun governing Wu (Wu belongs to Fire) is Wu Wu year; Metal Yun governing You (You belongs to Metal) is Yi You year; Water Yun governing Zi (Zi belongs to Water) is Bing Zi year. These are called the Four Cardinal Directions. Earth Yun governing the four seasons (Chen, Xu, Chou, Wei all belong to Earth) are Jia Chen year, Jia Xu year, Ji Chou year, and Ji Wei year. These are called the Four Intercardinal Directions, totaling eight years. Tai Yi Tian Fu refers to years that are both Tian Fu and Sui Hui, meaning the Heavenly Qi (Si Tian), Yun Qi (Zhong Yun), and Sui Zhi (Earthly Branch) converge. For example: In Ji Chou and Ji Wei years, the Zhong Yun is Earth, which matches the Earth Si Tian, and Earth Yun governs Chou and Wei (which belong to Earth); in Yi You year, the Zhong Yun is Metal, matching the Metal Si Tian, and Metal Yun governs You; in Wu Wu year, the Zhong Yun is Fire, matching the Fire Si Tian, and Fire Yun governs Wu. This totals four years. Tong Tian Fu and Tong Sui Hui refer to years where the Zai Quan Qi and the Zhong Yun belong to the same category of Qi. Yang years are named Tong Tian Fu, such as Wood Yun with Wood Zai Quan, like Ren Yin year and Ren Shen year; Earth Yun with Earth Zai Quan, like Jia Chen year and Jia Xu year; Metal Yun with Metal Zai Quan, like Geng Zi year and Geng Wu year. Yin years are named Tong Sui Hui, such as Water Yun with Water Zai Quan, like Xin Chou year and Xin Wei year; Fire Yun with Fire Zai Quan, like Gui Mao year, Gui You year, Gui Si year, and Gui Hai year, totaling twelve years. These differences in the convergence of Qi and Yun must be understood. There are twelve years of Shang Tian Fu, four years of Tai Yi Tian Fu, eight years of Sui Hui, six years of Tong Tian Fu, and six years of Tong Sui Hui. However, the four years of Tai Yi Tian Fu are already included within the twelve years of Tian Fu. Among the eight years of Sui Hui, four are also included within the Tian Fu. In summary, out of sixty years, only twenty-eight years meet these specific conditions (Figure 18-20).
