There was a man whose wife died in childbirth. Fortunately, there is a smart and capable dog in his family, which naturally shoulders the heavy responsibility of looking after the baby. One day, a man went on a business trip and came back very late. Knowing that his master had returned, the dog came out to meet him happily. But when the man saw that the dog's mouth was full of blood, an ominous premonition suddenly came to his mind, wondering if the dog ate the child because of the attack of hungry animals. So he hurried to the bed and saw no one, only a pile of blood. In a rage, the man picked up a stick and killed the dog. Who knows, just then, the child cried and climbed out from under the bed, and the man realized that he was wrong about the dog. He looked around and found a wolf lying not far away, killed alive. Look at the dog, its hind leg has been badly scratched. It turned out that when the man went out, a wolf slipped in and tried to steal the child. The dog bravely rushed up to fight the wolf and finally saved the child's life. When the man knew the truth, he cried and regretted it, but nothing could be changed.

Sean, a famous minister in the early Han Dynasty, met something when he went out to study. One day, he met an old man sitting there in coarse clothes on Xiapi Bridge. When he saw Sean coming, he deliberately left his shoes under the bridge and said to Sean, "Boy, go down and pick them up for me!" Sean was shocked and wanted to get angry. Because he is an old man, he tried to pick up his shoes under the bridge. The old man said, "Put your shoes on for me." Sean thought that since he found the shoes, he should do a good deed and kneel down to put the shoes on the old man. The old man put it on and left with a smile. After a while, he came back and said to Sean, "You are a young man who can teach." So I invited Sean to meet again. The old man later taught Sean the art of war, which eventually made Sean a good minister.

The old man's visit to Sean was to see if he had the self-restraint to bear the burden of humiliation. With this accomplishment, he can "teach as a willing child can teach", take on a big responsibility in the future, deal with complex interpersonal relationships and arduous things, be calm when things go wrong, know the advantages and disadvantages, and not be impulsive. Usually, we should pay attention to this kind of cultivation, restraint and patience, and handle the people and things we meet well.

The younger brother of Lou Deyi, the prime minister of the Tang Dynasty, is going to take office in the Governor's Office on behalf of the country. Before he left, Lou Deyi said to his younger brother, "I don't have much talent. I am now the prime minister. Now that you have state officials, you get more, which will cause others' jealousy. "What do you think?" His brother replied, "If someone spits on my face in the future, I won't say anything, just wipe it myself." Lou Deyi said: "This is exactly what I am worried about. The man spat at you because he was angry, and you wiped it off. This is an outlet to resist the man's anger. I'll do it without wiping my mouth. I might as well accept it with a smile. "

Brother Lou's words are a metaphor, not a joke, which means to be patient, to make concessions, and not to "point the needle at the wheat" with each other. Otherwise, it will further irritate each other, intensify contradictions and bring more serious consequences.
