What exactly does birthday mean? What do you mean by "eight characters are light" and "eight characters are heavy"?

Birthdates are four groups of trunks (trunk-branch calendar, also known as four columns) converted from the information of a person's date (year, month and day), time (minutes and seconds) and place of birth (province, city and county). The four pillars are composed of four groups of tree trunks: year pillars, moon pillars, sun pillars and hour pillars.

"Eight-character light" and "eight-character heavy" are related to the root qi (rise and fall) of the branch of the earth and the stem of the sun (referring to the fifth word of the eight characters). If the four-column branch has no root gas or weak root gas, it is called eight-character light. If an eight-character sun has strong roots in four pillars, it is called eight-character weight.

"Eight characters are light" and "eight characters are heavy" can not completely determine a person's fate, which is closely related to the pattern of birth and the success or failure of the Universiade.

Here is an example to illustrate:

Male, born at 0: 00 am (clock time) 165438 on August 4th, 1998, was born in Chengdu, Sichuan Province, so we can exclude his date of birth from the arrangement system as: Wuyin is unmarried.

Date of birth (Wu Yin has not returned to China)

Because the sun column of the birthday (Wu Yin has not taken off Ding, Ding Si has not taken off Ding) is the water of taking off Ding, and the water of taking off Ding has no roots in the four branches of the eight-character (year branch, month branch, day branch and hour branch), so the eight-character can be called light.
