Why is the yellow calendar the opposite?

Look at the sky, this kind of thing can't be generalized simply and mechanically. Good things happen on the same day, and bad things happen on the same day. For example, when the Japanese army announced its surrender in World War II, it was a good day for China and the people of the world, but it was a very painful day for the Japanese! For example, when a battle is over, the winner is lucky and the loser is unfortunate. ....

Therefore, the date is not based on the words in the book, but on the personal information of the parties (eight characters or gossip) to see whether this day is appropriate.

If you don't believe that much, you can find yourself a day with good weather and a good mood.
