This happened in my third grade of health school in June that year. The graduation exam had just ended. I was idle in the school, so I went to see my first grade class teacher, Mr. Chen, who has always taken good care of me. I am very grateful to her. I sat in Mr. Chen's office for a while and chatted about the past. As I was chatting, I talked about the human anatomy class she had recently taken. She said that all the classes she taught are girls now, and she was very stupid when she studied. She asked me if I could help teach my schoolgirls. Of course, I said no problem, because Mr. Chen is my favorite teacher and the first beautiful teacher in the school. A beautiful teacher like this asked me for help. Of course, I had no choice but to do so.
