What movie is Wei Zi in the calculation class of No.6 Middle School?

Wei Zi in the calculation class watched a movie called The Whistling Boy when she was in Grade Six. In this film, Li Meng plays Wei Zi, a middle school student. With his mysterious background, unknown story and detached temperament, he moved from a high-quality middle school to an ordinary technical school where the film story took place, and stood out as the most beautiful and unique scenery of this technical school. When all the students are either young and ignorant or have a boiling passion, only Li Meng seems to see through everything in this world. White skirt fluttering, long hair fluttering, with rare elegance of peers, has become the focus of the whole school, making boys uneasy and girls jealous.
