The rain hits the hibiscus branches, falling into the world of mortals and the fragrance disappears
The (fake) boudoir lady who looks gentle and considerate but is actually cold and cruel and the female general who seems to be distracted and likes to be silly but is actually shrewd and cold.
No matter how smart you are, you can't be as smart as someone else's boudoir lady.
Purpose: People need to be smarter, otherwise there will be no scum left that is easy to be eaten.
