I know this teacher. Our teacher on the fifth floor feels ordinary. On the fifth floor, he should be the teacher with the most work and the least money. He works too much. He is in 200 yuan for a month, and his monthly living is less than 100 yuan. Other teachers will pay at least 500 yuan on time every month, whether you do it or not. Scientific research feels the same. Graduate students have to rely on themselves. Now many teachers are no longer teachers, and even more businessmen than businessmen. Who will take care of you? Unless he has something to do, he will ask you to help him, rely on himself and his classmates. If you want to know about the teacher, you can ask his students or the teaching and research section next door about the topic to be discussed after dinner. Everyone knows that.
