Sixty-six-year-old Tang Guizhi joins a community literacy mutual aid class. After eight months of study, she and her old classmate Cheng Yulan finally usher in the day of course completion. Her daughter Tang Xiaoqing wants to prepare a formal graduation commemoration for her mother, yet in her good intentions overlooks the life feelings her mother truly wants to express. Her granddaughter Doudou accompanies grandma in practicing her speech, and slowly comes to understand the meaning of this graduation for her. Accompanied by her family and encouraged by her old classmate, Guizhi decides to narrate this experience in her own words, and the four of them ultimately complete a simple and warm graduation sharing, leaving behind a precious group photo belonging to ordinary life.
