My Teacher Is Xiao He (2016)

At Qi Ying High School, class 2B is known to be a class full of troublemakers with poor grades - a helpless bunch. One day, He Qian Dai, later nicknamed Teacher Xiao He by her students and fellow co-workers, becomes the homeroom teacher of class 2B. Despite being an inexperienced teacher, she immediately takes them under her wing as both a mentor and a friend. Due to her influence, the students of class 2B grow and bond through mistakes, misunderstandings, and friendships, while the other teachers at Qi Ying slowly come to see the naive Teacher Xiao He, as well as the "trouble-making" students, in a new light.
