What is three yuan nine luck?

Sanyuan Jiuyun is a method to divide China's time. The ancients divided 20 years into one luck, and three 20 years were three luck to form one yuan. The ternary games are Shangyuan, Zhongyuan and Xia Yuan, which are collectively called "Sanyuan Jiuju". Shangyuan is the first, second and third luck; The Central Plains is the fourth, fifth and sixth luck; The next yuan is the seventh, eighth and ninth luck. 60-year delivery per yuan, 3 yuan total 180 years.

Among the nine planets in the solar system, Saturn and Jupiter meet once every 20 years and are in a straight line; Saturn, Jupiter and Mercury will meet once every 60 years. Every 180 years, the nine planets will be on the same side of the sun, distributed in a small fan shape, forming a "nine-star connection". Because the operation law of this celestial body will never change, scientists have defined the time system of "three yuan and nine luck" according to this law, with 180 as the positive element, and each positive element is divided into upper, middle and lower three yuan, each for 60 years, and each element is divided into three luck, that is, one to nine luck.

Extended data:

Ancient scientists in China observed that Saturn and Jupiter met once every twenty years, in a straight line. When civil engineering meets, some major geological disasters and natural disasters often occur on the earth, and people's behavior will also have some obvious abnormal reactions.

It is also found that Saturn, Jupiter and Mercury will meet in a straight line every 60 years, and the nine planets in the solar system will be on the same side of the sun every 180 years, forming a grand gathering of the nine planets, which ancient astronomers called "nine-star alignment".

This celestial body goes round and round and never changes. The ancients knew this opportunity well and established the system of "Three Yuan and Nine Games" to divide the time: 180 was taken as a positive element, and each positive element was divided into Shangyuan, Zhongyuan and Xia Yuan; Sixty years per yuan, and then divided into three batches, each batch of 20 years, that is, Shangyuan is the first batch, the second batch and the third batch.

There were four, five or six performances in the Yuan Dynasty, and seven, eight or nine performances in the Yuan Dynasty. In this way, a complete ternary nine-luck system has been formed. The nine movements are divided into three groups, which are called "Yuan Yun".
