How to calculate the division of twelve gods?

This arrangement is simple. It has something to do with Liuren, but I don't know much about Qimen. You should know the order of calendar months, starting from the first month is silver moon, next month is Uzuki, and so on; In addition, the order of the twelve stars is to establish, remove, fill, calm, break and close the crisis. The calculation method is as follows: the date of establishment of silver moon is the star of establishment, the date of establishment is the star of withdrawal, and the date of establishment is the full star. Then, you can refer to Dong Gong to choose a date to judge good or bad luck. But beyond that, it still depends on Tian Ke Di Chong and Twenty-eight Nights.
