Overview:This film tells of a young girl who grew up in a snack bar in the old city but was full of stubbornness and a beautiful and self-proclaimed Bai Fumei school flower. Because of an accident, a completely different life was exchanged. They hate each other, but have to carry each other's body forward. In the contradiction and playfulness from time to time, from tit-for-tat to tacit understanding; in the adventure of exchanging life, understand what it means to help others to achieve themselves! Eventually realized their dreams, won the school flower crown, and inherited the cultural essence of their ancestors. More importantly, I have known different people and realized growth and transformation!
