Remember to eat but not to fight is a common saying, and it is also a Northeast dialect, which means that swearing people don't accept lessons, but only remember the benefits and forget the hardships. Metaphor means that some people are heartless, don't learn lessons, and repeat the same mistakes. This is a derogatory term, especially referring to people who made mistakes and learned lessons after the Nuo Nuo incident. For example, a child who doesn't do his homework is called a parent. After returning home, he was beaten and told his parents that he would never dare again. As a result, he was soon called a parent because he didn't do his homework. This is called remembering to eat and not to fight. As folk proverbs, proverbs, like idioms, are part of the whole Chinese language, which can increase the uniqueness and vividness of the language. But proverbs and famous sayings are different. Proverbs are the practical experience of working people, and famous sayings are said by celebrities.
