How to coax the teacher when he is angry?

Yo, it seems that you made your teacher angry. It doesn't matter if it's not enough. 1. Be active in class, don't be absent-minded, let the teacher think you are wrong and decide to correct it. 2. Send gifts to the teacher secretly. 3. Get good grades in the exam. 4. Contribute to the class. 5. Go to the teacher's office and tell the teacher a joke (but not that kind of cold joke).

It's gone. . . . . .

I hope the landlord will adopt it and it will definitely work. Someone in our class tried, and the teacher suddenly got angry.
