从语法角度,对“人不知而不愠”可能存在的四种理解方式逐一进行探讨,为读者合理理解这句话的含义提供参考。一是别人不知道自己,自己却不为此而生气;二是别人不采纳自己的政治主张和治国思想,自己却不生气;三是别人不懂(学不会),自己却不为此而生气;四是自己不懂(无知),自己却不为之生气。 From a grammatical point of view, we can discuss one of the four ways of understanding that “people do not know or not,” and provide reference for readers to understand the meaning of this sentence reasonably. One is that others do not know themselves but do not get angry with them; second, others do not get angry when they do not adopt their own political ideas and governing the state; third, they do not understand (learn not to) Angry; Fourth, they do not understand (ignorance), but they are not angry.
