What do you mean by "taboo: nothing is suitable" and "suitable: remove, break the wall and don't take the rest"

Appropriate here should mean appropriate. There are things that are forbidden to do in the yellow calendar, and there are also things that are suitable for every day.

Dissolution: refers to washing and cleaning houses, eliminating disasters, etc.

Bad wall: refers to the removal of the fence.

If you don't take anything else, you don't do anything else, which is second only to others.

But it would be contradictory if it was written on the same day.

Anyway, I wish you a happy marriage.
