It is difficult to be a guardian in the promotion education. I used to work there. I go to work at nine o'clock every morning. After work, I came to the campus to clean and prepare lessons. Teachers should study together. After receiving the child. After dinner, organize children to have game classes and good habit classes. Children do homework, teachers can't rest, and teachers have to take care of their parents. There is a study exam at least once a week, as well as teaching and research activities. I get off work very late at night, and I can't get off work until I have tutored all the children. After the children leave, they have to communicate with their parents' home and school. So it's really hard, not ordinary people, you can do it.
