What is a birthday?

Date of birth, or constellation for short, refers to the calendar date when a person is born. This is actually the same meaning as the birthday we are talking about now.

In fact, the calendar uses heavenly stems and earthly branches to represent the year, month, day and time.

Ten days of work: A, B, C, D, E, Ji, G, Xin, people, ghosts.

Twelve earthly branches: Zi, Ugly, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai.

This calendar represents time, and heavenly stems and earthly branches has one word for each. In order, it is from Jiazi, Emei ... to Guihai, which is exactly 60 groups in a cycle.

The year, month, day and hour are called "four pillars", and each pillar is represented by "a day's work+a place's branch", so it is called "eight characters".

Four-column push

Four pillars refer to the time when a person was born, that is, year, month, day and hour. When people use "heavenly stem" and "earthly branch" to represent year, month, day and hour respectively, such as Jiazi Year, Bingyin Month, Xin Chou Day and Renyin Time. There are two characters in each column and eight characters in four columns, so fortune telling is also called "batch of eight characters"

According to the nature of yin and yang and the relationship between the branches and branches of the five elements, it is speculated that people should forgive and blame, and using four pillars to push fortune-telling is also called fan fortune-telling

This fortune-telling method is also called astrology because it evolved from ancient astrology. People in ancient China believed that heaven and earth corresponded. The geographical distribution of Kyushu corresponds to the stars, and all beings correspond to the stars. The gold, wood, water, fire and earth that make up the world also correspond to Venus, Jupiter, Mercury, Mars and Saturn in the sky.
