The birth of astrology promoted fate.

According to people's birthdays, the fortune-telling method is also called Sanshengshu.

Its theoretical basis is the theory of innate qi founded by Wang Chong, a thinker in Han Dynasty, which holds that everyone has innate qi. Grasping the nature of the innate qi of Yin-Yang and Five Elements when a person is born and the law of restraint can reveal all the fate news in his life.

There are different opinions on the origin of pushing fetus, which is difficult to verify. On the one hand, Luo Lu Zi originated from the Warring States period, and on the other hand, it originated from Guiguzi. Both of them are not supported by historical data and cannot be trusted. It is also said that during the Six Dynasties, Tao Hongjing learned the art of Sansheng, and he wrote a book "Sansheng Copy", but this book has not been handed down from generation to generation. "Forty-nine Jifangfu Beiqi Books" contains: "Wei Ning, Julu Man. Be a good guest of Lu's life. Wu tried, and all succeeded. I asked him according to my date of birth, and I would rather say,' Very rich, I am buried this year.' Wu Cheng was frightened and said,' It's me! Yongbyon said,' If you are the emperor, you will have your own laws.' There is another skill, saying:' rumor:' Lu 16, Luo 14, slap the head 32. And there are too many times in four or eight days, I'm afraid it's not enough. Wu Cheng was thirty-two years old when he collapsed. "It can be seen that it was only the date of birth, and the method was quite simple. By the Tang Dynasty, Sansheng had been improved by numerologist Li, and had a new development. During the Northern Song Dynasty, another warlock, Xu Ziping, annotated three pieces of life information in Luozi, combining the year, month, day and time of a person's birth with branches and branches to infer good or bad luck, which made the timing theory more complete. In the process of the spread of the eight-character divination, some people have also modified and renovated it, creating a variety of methods of divination, such as calling the five elements, setting the five elements, the tongs of the two sessions, and the tiger on the ground. However, these are far less profound than the eight-character fortune telling.
