"Girls' School" is a touching film about love and growth. The background of the story is set in a conservative girls' school. The protagonist Chen Zifeng (Chen Hou) is an enthusiastic chemistry teacher, and Li Hailun (Li Jing) is his childhood sweetheart and also works in the school. Chen Zifeng picked up an abandoned baby in the school's infirmary by chance one day. With kindness in his heart, he decided to take the child back to school and take care of it
However, this kind act caused quite a stir. The students began to circulate various rumors about the baby, claiming that the child was the illegitimate child between Chen Zifeng and Li Hailun. Faced with these accusations, Chen Zifeng and Li Hailun chose to remain silent, because they knew that such an explanation would not be easily believed and would only make things more complicated. They chose to use actions to prove their goodwill, and believed that time would clarify everything.
With the efforts of Chen Zifeng, the atmosphere of the school has gradually become warm and harmonious. He encouraged students to have a strong interest in chemistry, and demonstrated the charm of knowledge with vivid and interesting experiments, making the boring subjects full of fun. And Li Hailun organized a series of public welfare activities in the school, leading the students out of the campus, caring for the society, and helping those in need with practical actions.
