The next day, the teacher shows the students the carving materials that his father has given him. The teacher says that he will accept the gift, but warns them not to show it to him if it is not an emerald. He says he can cut it for them if they want, even if the emerald is an ice one. He curses himself for getting into trouble for himself. He asks the teacher to show him the best carving materials. He is curious about the quality of the jade. He notices that the pieces of jade that weren't cut were in the middle of the wall. He tells the teacher that they must be worth the material. He shows the teacher other jades after he cuts them. The green glass emerald is a gift from the teacher, and he says he won't accept it from anyone else, but he will give it back to the teacher as a gift when it is finished. He adds that he can also enjoy carving good things. He explains that the purpose of carving is to increase the value of jade, but that he must tell the teacher something.
