Mo Xiangwan was born in a small town in the south. He comes from an ordinary family and has top grades, but he has three inferiority complexes - short height, introverted and sensitive personality, and a sense of "unworthiness" brought by his native family. She got out of the small town by solving questions. On the way to study, find a job, and become a teacher, she constantly struggled with height anxiety, personality defects, and her family of origin. She finally accepted all of herself and became an outstanding teacher with warmth and strength, achieving reconciliation with herself, the past, and the world.
