Excuse me, what does Cheng Wei or others mean in the yellow calendar? Can you introduce it in detail? thank you

Success and danger are two terms in the yellow calendar. According to the monthly construction, twelve satellites are arranged in the ancient calendar, namely, construction, division, fullness, leveling, determination, persistence, breaking, danger, success, closing, opening and closing. Among them, the methods of dividing good luck and bad luck are as follows: buildings are full and closed in black, dangers are eliminated and yellow is held, and opening and closing can be used. The so-called yellow is the day of the zodiac, which is an auspicious day. This is something that the ancients were superstitious about. I hope you can refer to it.
