When a 68-Year-Old Cool Lady Decided to Go Back to School

In order to protect her bullied granddaughter Lu Tong, 68-year-old Xu Fengqin decided to put on her school uniform and return to her senior year class. Faced with the arrogant school bully Yang Yuxin and his associates, she adopted the attitude of "not causing trouble but not afraid of it". From having her monthly exam results tampered with to outsmarting the principal in the broadcast room, Xu Fengqin used her strength to prove that age is just a number, and being cool is a lifelong thing.
