Yang Mi is an authentic Hutong girl in Nancheng, Beijing. When she was a child, her family lived near Niujie Street. She was good at playing table tennis, badminton, swimming, and skating. When she was a child, she was quite naughty. Children from other families were learning piano, dancing, and calligraphy, but she couldn't calm down when learning anything. At that time, the China Children's Film Studio held a children's film and television performance training class, and Yang Mi's parents hugged her. He took her to sign up with the mentality of giving it a try, but Yang Mi, who was under age, was admitted by the admissions teacher.
