What do you mean, old lady is always?

Tai sui is the abbreviation of Tai sui God in Taoist belief and one of the gods worthy of years in Taoism. It changes every year. The Tai Sui God who was rotated in those years was called Tai Sui (fleeting Tai Sui).

The belief in Tai Sui originates from the worship of celestial bodies among the ancient people in China, and has a certain relationship with Jupiter. The ancients observed the celestial phenomena and thought that a year-old star runs once every twelve years, so they divided the ecliptic into twelve equal parts.

After the Warring States period, for the convenience of timing, the imaginary "Tai Sui" is left-handed, which is contrary to the actual direction of the old star (right-handed), and the year is calculated by the part where Tai Sui is located every year.

Since the Qin and Han Dynasties, people have regarded Tai Sui's position as a fierce party. No matter who it is, no one dares to go against the fierce party where Tai Sui is located, such as building a house or moving to get married, otherwise even if it is in Tai Sui's head, it is likely to cause great disaster. Later generations personified too old; After the Yuan and Ming Dynasties, it was listed as a sacrificial ceremony by the state, offering sacrifices according to age, praying for the old star king to assist the country and people.

Extended data:

Ancient astronomers found that Jupiter is the largest planet in planets of the solar system, which has a great influence on the earth, so Jupiter is used to represent the year. Jupiter orbits the sun at 12, which is the origin of the zodiac, that is, the twelve branches. But ancient astronomers also found that Jupiter actually runs for 1 1.86 years, so it will overtake Chen (proposed by Liu Xin in the Western Han Dynasty) every 84-87 years.

In order to avoid the problem of transcendence, a celestial body is assumed and corresponds to Jupiter. At the end of the Han Dynasty, Liu Xin changed the first year of Taishu to Bingzi, and the second year of Taishi (the first 95 years) from Yiyou to Bingxu. In this way, the conflict between the branch chronology and the ancient chronology can be solved, that is, the problem of Jupiter's transcendence. This hypothetical celestial body is too old.
