There is a teacher named Fu in our third middle school. I forgot his name. I used to learn from him. He teaches very well and solves problems in a very special way. He used to teach in his hospital next to No.3 Middle School. I wonder if he is still here.
Individual tutors can be paid in one lump sum ~ he is easy to talk (to be precise, he is not good at talking). He is the reason why I didn't get below 120 in high school mathematics.
