What do puppets, chess pieces and puppets mean?

Needless to say, the original intention. There are some differences in referring to people: puppets are the most serious and manipulated by people, just like humanoid wood; Puppets are restricted, they can have their own thoughts, but they can't do anything special. The Yellow Emperor in the hands of Cao Cao in the Three Kingdoms is a puppet. Chess pieces are designed and used by people, and their thoughts and actions are not restricted, but every step is not allowed to be divorced from other people's plans. Knowing that you are a chess player, you can't change it into helplessness; Being caught in a chess game without knowing it is ignorance; Most people who know chess without complaining are grateful.
