Trapped for a long time by her weight, her mother's control, and outside evaluations, Lin Zhixia is sent to live on a tea mountain for ninety days. With no delivery food, no bank cards, and no shortcuts to escape, she must learn to feed herself, make money, and walk down the mountain on her own. From emotional eating and fearing others' gazes to selling tea, handling returns, organizing helpers, and keeping accounts independently, she reclaims the initiative in her life step by step. Ninety days later, she is able to leave, but for the first time, she chooses to stay. What truly changes her is not the number on the scale, but finally learning to take responsibility for her own life.
