Who said' tolerance is the greatest virtue'?

Most people have seen Princess Huanzhu, and Wei Zi was bullied by the queen in every way, especially by Rong Yao. When the emperor finally tried to kill Rong Yao, Wei Zi had to come up with a "death-free gold medal" to plead for Rong Yao. When Rong was killed, he had to recite "Don't hit poetry" so that the emperor ordered "Don't hit" and saved Rong's life. I still remember what Wei Zi said at that time, that is, "To be a man, you should learn to be tolerant, and tolerance is a person's greatest virtue".
