Are the four pillars from Zhouyi? I read the book Zhouyi, but it's not at all. I think it comes from the theory of yin and yang and five elements.

Four pillars are discharged when they are born, and are composed of eight branches. Also known as horoscope.

Annual column:

It is the year when a person was born, which is represented by the branches of the lunar calendar. It should be noted that the dividing line between last year and next year is based on the intersection time of "beginning of spring", not on the first day of the first month.

Moon column:

This is a festival that uses branches of the lunar calendar to indicate the date of birth. It should also be noted that the monthly stem and the monthly branch are not divided by the first day of each month in the lunar calendar, but by festivals. Before the handover, it was the festival of last month, and after the handover, it was the festival of next month. These people, including the director website, are mistaken.

The earthly branches in the moon column are fixed every year, starting from silver moon and ending from the ugly month. The first month of every year is silver moon, from "beginning of spring" to "Jingzhe".

Rizhu:

It is the date when a person is born, which is represented by the branches of the lunar calendar. Branches of the lunar calendar are recorded every 60 days. Due to different months and different leap years, the Japanese branch needs to find a perpetual calendar.

Time bar:

The time of birth is indicated by the lunar calendar of the lunar calendar. One hour spans two hours in the lunar calendar, and there are twelve hours in a day.

The ground branch of the time column is fixed, but the sky is dry, so we should "set the timetable from morning".

In addition, the numerology is 23 pm. Before 23 o'clock is the last day of Shihai, and after 23 o'clock is the next day. Please pay special attention to this point, and don't think that midnight is the dividing point of the day.

The four pillars represent the position of the sun when a person is born, and the fate of a person's life is calculated according to the principle of "harmony between punishment and life" of yin and yang and five elements. It is a summary of the natural movement law of human destiny by our ancient ancestors.

The ten-day drought is related to the appearance of the sun, and the cycle of the sun has a direct impact on everything.

Heavenly stems and earthly branches, referred to as Ganzhi for short, is used to arrange year numbers and dates. A heavenly stem and a terrestrial branch are arranged in pairs, with the heavenly stem in front and the terrestrial branch behind, the heavenly stem from the nail, the terrestrial branch from the child, the yang stem with the yang branch, and the yin stem with the yin branch (the yang stem without the yin branch and the yin stem without the yang branch). Sixty combinations are called "Sixty Jia Zi".
