Mr. Douyin Maomao is not a teacher, she is just a video blogger on Douyin who often shoots short dancing videos. Teacher Maomao’s real name is Mao Yulin, 46 years old. But she looks less than 30. All this is closely related to Teacher Maomao's passion for physical training. She does some yoga every day and posts some of her dancing videos on Douyin. The above information was obtained from Tieba.
