I think Fan Li should be a person who has a deep understanding of human nature. Because he understood Gou Jian as a human being, he avoided the negative effects caused by his superior achievements. However, the end of Wenzhong was not so good. Fan Li When he advised him to make plans early, he still thought that he had made such a great contribution and it was too late for Gou Jian to be grateful to him. Later, when he was executed, he left the words "The cunning rabbit dies, the lackeys are cooked; the birds are gone, but the good bow is hidden." timeless saying.
