Which teacher left a deep impression or influence on you?

The best teacher I have ever encountered. She is the professor who teaches college English in my university. The old lady must be in her fifties or sixties. Shanghainese. He should be a professor in one of the most respected English groups in the province. He has a relatively high status and has more physical strength than us every day. Running to class. Be happy. She mingled with us, and from time to time in class she would intersperse some of her own understanding of academics, work units, differences between boys and girls, and life. I used to think that professors were all serious and dull. Or putting on airs. But she's not. I treat all my classmates as friends. He often makes fun of himself. He also talked about the things he didn’t do well. I am not sure about some accents in Mandarin, and sometimes I arm-wrestle with the boys in our class after class. Sometimes we go to a barbecue with our class organization. Sometimes he tells jokes in class. He is the brightest and most optimistic person I have ever seen. I have been to Europe, the United States and many other countries around the world. Speaks three or four languages.
