First, the main branch
Heavenly stems and earthly branches is the collective name.
There are ten days to work: A, B, C, D, E, G, Xin, Ren and Gui.
There are twelve branches: Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai.
The five movements are the five elements: wood, fire, earth, gold and water, too much and too little.
Wind, cold, heat, dampness, dryness and fire represent three Yin San yang.
Second, China traffic (five games)
On the basis of observing astronomical phenomena, the author of Huangdi Neijing expressed an annual movement change with the connection between heavenly stems and five elements.
Tiangan represents five kinds of sports: Jiaxu, Yigengxu, Bingxin, Dingren and Huo. Among them, Gan Yang means A, C, E, G, N, which means too much; Dry in the shade means that B, D, G, Xin and Gui are all inferior.
Third, the division of heaven and the branch of spring represent the six qi, which mainly shows that the six qi are the division of heaven and the division of spring. "Four days" and "complete again" are two unique concepts in Luck, and they are also two relative concepts. When the sky is determined in spring, it is also determined. There must be three yin springs in three fields, and three yang springs in three fields. Among them, Huangdi Neijing clearly stipulates the order of three yang, that is, one yang is shaoyang, the other yang is Yangming, the third yang is sun, the first yin is Jueyin, the second yin is shaoyin, and the third yin is Taiyin. The relationship between Sita and Zaiquan is one-on-one, two-on-two and three-on-three. That is, one yin (Jue yin) dominates the sky, and one yang (Shao yang) must be in spring; One yang (less yang) dominates the sky, and one yin (Jue yin) must be in spring. And so on.
The division of heavenly stems is indeed determined according to the year when the earthly branches are in the main branch, that is, in the middle of the meridian, Yin Jun is divided into fire and heavenly stems, ugly years are divided into Shen Yinhuo and heavenly stems, You Mao years are divided into dry Yangming and heavenly stems, Chen Xunian is divided into cold sun and cold water, and Hayes years are divided into evil winds and heavenly stems.
In the spring after the date is determined, it is easy to calculate according to the principle of relative yin and yang. If it is sunny, it will be cloudy in spring. If the sky is cloudy, it must be sunny in spring. That is, one yin (Jue yin) dominates the sky, and one yang (Shao yang) must be in spring; One yang (less yang) dominates the sky, and one yin (Jue yin) must be in spring. And so on. For example, this year (2006) is the third year and the underground branch is the ninth year. So this year is the day when the sun is cold and the water is cold, and the soil is too wet in spring.
Fourth, the main qi.
Main qi refers to the constant qi divided into six zones (from severe cold festival to minor cold festival) every year. In other words, no matter which year, the distribution order of six qi is the same. Among them, the sequence of six qi and the time zone dominated by each qi are briefly described as follows:
