I have a "caricature teacher". He was tall, with a slightly chubby face, dark hair, and most strikingly, a pair of shining eyes like black jewels and a cute, handsome smile that lifted from time to time.
Our whole class loved him very much, in class he was always meticulous, patiently pointing out each student's mistakes, his language was so vivid, his singing voice was so beautiful.
Sometimes he also used some funny moves, often amusing the students laugh, but he was also very strict with us when he was talking about some important new knowledge, and then the class would be silent and listen to him carefully.
