Did the Yellow Calendar of Nanjing Observatory mention seven policies and four redundant lines, including scraping, returning and staying?

There is no Nanjing Observatory, only the Purple Mountain Observatory. By the way, it's not the Nanjing Purple Mountain Observatory, but the National Purple Mountain Observatory.

The Purple Mountain Observatory publishes an astronomical almanac every year, but it is not a yellow calendar, and there will never be anything about the location of the god of wealth, good fortune or taboos.

However, there is a considerable space in the astronomical calendar to calculate the position of the planets, when the planets will go straight and when they will stay in the horrible calendar (what is the latitude and longitude of the planets at a certain moment? The eight planets give a data every ten minutes, accurate to 0. 1 ").
