Wang Tiancheng is a freshman at a prestigious university in X City. His family is poor and he still has a lot of spare time in his freshman year. In order to earn some living expenses for himself and make his parents less hard, he posted a tutoring information on the school and earning some living expenses. On that day, there was no class at night, Wang Tiancheng reviewed his homework in the study room and started to buzz. He ran out of the study room. A voice full of mature women came from the other end of the phone: Hello, is it Wang? Hello, I am Wang Tiancheng, who are you? Wang Tiancheng is very polite. I am a student parent. When you see the tutoring information you posted on, I want to ask you to tutor for my daughter. If you have time, can you come to my house?
