The next morning, zhiying sends a new edition of the letter to the teacher. He tells her that he will show it to her when there is no big problem. Shen sheng asks if he is free now, and he replies that he is. He asks if she has a sharp tongue, and she says that he already said that. He says that she is helping an outsider, and that she should not push him. She tells him that they will meet at school during the weekend, and they will discuss the matter together. She says that they should not discuss it themselves, as she is not going to live with them. She asks why he did not accept the one she rented for him, and the teacher replies that she needs to pay half the rent to him, but she refuses to give him the money. He will come back soon, she says, and knock on the door, and then he will return soon and knock again.
