What is the origin and meaning of the allusion to chop and change?

Chop and change is an idiom, which comes from Zhuangzi's theory of everything in Zhuang Zhou. The original moral of this story is a clever irony of two kinds of fools, one is the manager and the other is the managed. The latter is ridiculous because' one leaf can't see Mount Tai'; The former, seemingly arrogant, used to do some "self-deception, expedient measures and delaying tactics" only to solve the immediate predicament, and naturally it was resented because it was not a long-term solution. Now, it extends to men who are fickle.

Tracing the origin of the allusions of "Three Falls and Four Falls";

There is a story in Zhuangzi Wuqi: Song people raised a large group of monkeys. He can understand the monkey's thoughts, and so can the monkey. This man always satisfies the desire of monkeys by reducing the food ration of the whole family, but soon, there is a shortage of food at home. He wanted to limit the number of acorns that the monkeys ate, but he was afraid that the monkeys would not listen to him, so he coaxed the monkeys and said, "I'll give you three acorns in the morning and four at night." Is this enough? " Monkeys used to have four chestnuts every morning and evening, but now they all stand up angrily when they hear that there are only three chestnuts in the morning. He added, "Four chestnuts in the morning and three chestnuts in the evening are enough?" As soon as the monkey was moved, the chestnuts changed from three to four, and then they obeyed. This is the origin of the story of "chop and change". It means: it means to play tricks and deceive people. Later, the metaphor often changed his mind and was capricious.
