As mentioned earlier, the ancients used dry branches to mark the year, month, day and time. Someone was born at a certain time in a certain year, and together they have eight characters, which is called this person's eight characters. According to these eight words, the fortune teller infers the fate of this person and draws the conclusion that there can be several men and women when a man marries a woman. This is obviously nonsense. Of the eight characters, the first two words are the main branches of the year, but in ancient China, beginning of spring, slight cold, heavy snow and beginning of winter were the first year, and beginning of spring was the first year after Emperor Wu of the Han Dynasty. Every year, the main branches are counted from the beginning of the year, so the beginning of different dynasties is different, so the main branches are different. The result is that the same person can have different horoscopes. For example, this year is the year of Jiazi, and some people were born between 10 and 12 last year. Shang, Zhou and Qin dynasties said it was Jiazi year, and Xia dynasty said it was Guihai year. In addition, there are different solar terms in the lunar calendar, and fortune-telling should be based on the solar terms in the capital (that is, the capital). However, there are also differences in the location of the capitals of different generations, so the branches and branches in 2008 did not "fall from the sky" and can be transferred with the personnel. So, inferring human destiny is not a tree without roots? The third and fourth characters in the eight characters are the main branches of the month, which has nothing to do with the month. As far as the main branches are concerned, each year is limited to 12 months, and the months are replaced by solar terms, that is, beginning of spring is the first month festival and the fright festival is the February festival. For example, in beginning of spring, the fourth day of the first month, before the third day, it belonged to the trunk branch of last year1February, and it was only after the fourth day that it was counted as the trunk branch of the first month of this year; Or1beginning of spring on February 26th, which belongs to the main branch of this year1February before 25th, and belongs to the main branch of the first month of next year after 26th. The dates of solar terms are different, even if the solar terms in the capital prevail, the branches of the Tang, Song, Yuan, Ming and Qing Dynasties are different. In short, the branches of the year and the month are active, both of which are active. How do fortune tellers choose the branch of the year and month? The fifth and sixth characters in the eight characters are the main branches of the sun, and the seventh and eighth characters are the main branches of the time. The main branches and time of the day should be combined to make it clear. Because of the different longitudes, the time between the east and the west is different. Time can be divided into normal time, local time and standard time. For example, if every year is based on the main branch of the capital Beijing, then the date and time of the main branch should also be based on Beijing. Then, people who were not born in Jilin, who were born in Xinjiang, should tell their fortune at noon (that is, at noon 12), or people born in Shen Bing, Jilin, who were born at the end of Xinjiang, should also tell their fortune in Shen Bing (that is, at midnight), so that the system will not be chaotic. Have fortune tellers and gentlemen who approve astrology ever used this method to tell others' fortunes? Obviously, they can't do it at all. In this way, the so-called eight characters are not only artificial, but also unreliable. This is a superstition without scientific basis, so we must get rid of it.
