Because when Confucius was taking roll call in class, he found that the student Zaiwo did not come to class and did not ask for leave. He was worried that something would happen to him, so he took other students to Zaiwo's home to look for him. He did not expect Zaiwo to be at home. While sleeping, Confucius got angry and said: "Rotten wood cannot be carved." After this sentence came out, it was often used by everyone to describe a person who was useless.

Confucius gives everyone the impression that he has a super good temper and has no choice in how to deal with others, but do you know? Confucius was not always polite. He also used "dirty words". This classmate who forced Confucius to use "dirty words" was just trying to kill me.

According to the record in "The Analects", one day, Confucius called all the students to come to class. Before class, Confucius began to call their names. At the end of the roll call, he found that Zaiwo did not come to school. Confucius was very worried that he would encounter someone. Something happened and it was too late to ask for leave, so I took other students with me to Zaiwo's home to look for him.

Confucius couldn't stand this situation of not following the rules. He felt that the day was for studying and sleeping could only be at night. This would kill me for sleeping during the day, and Confucius exploded completely, and he was so angry that he cursed: "This guy is just like rotten wood, unable to be carved, and like a wall covered with dung, there is no need to paint it!"< /p>

No one guessed it right. Zaiwo went to sleep at home without thinking that he was a student and had to go to class. When Confucius saw this, he was so angry that he said to Zaiwo: "Rotten wood cannot be carved." After Confucius said this, he took the other students and left.

Finally, I would like to say that Confucius lived in ancient times. If he were a teacher in modern times, he would probably be angry to death, and he would probably not be able to be saved.
