Zhou: Teacher Zhao, are you afraid?
Zhao: What am I afraid of?
Zhou: Think about it when you get sick in the future. The person who goes to the hospital to give you an infusion may be your student. The midwife who gives birth to your lover in the future may be your student. Let's look at the department your student is currently failing in. Aren't you afraid?
Zhao: Maybe my lover will be more afraid than me in the future.
Zhou: Why, your lover doesn't know, are those doctors and nurses your students?
Zhao: (Beeping quietly) She may know better than me
Purpose: Doctors do not heal themselves, people do not save themselves
