How old is Fu Sui?

Paying age refers to a term in human fortune telling, which means giving age. That is, between two bad years, if a good year appears, there will be another difficulty, that is, a bad year, so you need to be careful every year, because you can't be sure which year it is.

"Sui", also known as "country" and "Tai Sui", was the star name of that era. In the ancient imperial era, 18 years old had a prototype. According to ancient books such as Pangu Wang Biao and San Tong Ming Hui, "the first name of the emperor is determined by the age."

This invention of the emperor system has a far-reaching influence, and later generations have used it in calendar, arithmetic, calculation, naming and so on (Zi Tongzhi Jian, the official history compiled by the Northern Song Dynasty, is based on this set of official terms).

Correlation between years:

Every month of the lunar calendar should conform to the moon phase, and a lunar month is about 29.53 days.

If 12 months is regarded as a lunar year (average year), a year of 353-355 days is shorter than one year old.

When1March is the lunar year (leap year), one year is 383-385 days longer than one year.

If we take 12 months as a year, or 13 months as a year, as time goes on, the gap between years will get bigger and bigger.

Therefore, "the time interval determined by the calendar organization 12 or 13 lunar month" is a lunar year. So "year" is about equal to the average length of "year".
