How to coax your girlfriend to cry because she feels wronged in class?

There is nothing to worry about. Sweep the floor, wash dishes and wash clothes, beat your legs, rub your shoulders, knock your back and pinch your feet. As long as you do everything you can, when you are tired and sweaty, her anger will naturally disappear. People who reach out and don't smile, if they are angry with their girlfriends because of mistakes, can pull down their faces and greet them with smiles, and have the cheek to apologize and admit their mistakes. Feelings need to be communicated. If there is any small friction or misunderstanding, it will be all right.
