During the spring and Autumn period, Zai Yu, a disciple of Confucius, was very good at speaking beautiful words. At first, Confucius liked him very much and thought that he would be promising. But soon Confucius found that he often didn't come to class. He sent people to look for him and found that he was sleeping in his room. After knowing this, Confucius said sadly, "rotten wood can't be carved, and walls like dirt can't be painted."
