Before the Song Dynasty, numerology took the year master as the core of numerology, so it was called year life and great life. Later, it was changed to an "ID" centered on daily work. Other branches related to "ID" are called finance, government, printing and food. The Japanese stem is the heavenly stem on the day of birth, the sixth word in the eight characters, and the positioning center in the four pillars. Without this positioning center, life will be at a loss, so it is also called yen, the Japanese Lord; Referred to as "body", that is, "self". The so-called "weak body" refers to the strength of the yen.
Take the following eight words as an example:
Octyl methyl heptyl
Maohai Chen Wu
Xin's position is called Niangan; This position is called Yuegan; This position is called Japanese dry, also called Japanese yen and Japanese Lord; Geng's position is called.
The whole four pillars can represent a complete person, at this time, daily work is the core of people; When inferring people who are closely related to the Lord according to the four pillars, the daily work represents the Lord himself, and the other ten gods represent the six relatives. Therefore, daily work is the core of the eight-character life theory.
