A Falsetto Boy.

Winter 1996, Harbin. Sha Guo, a boy with a uniquely feminine singing voice, loves to sing but faces bullying and isolation at school, along with strict control and pressure from his obsessive mother. By chance, he meets Sitiao, a nightclub host and stage director. To defend his dignity, pursue his dreams, and find his true self, Sha Guo leaves home and, with Sitiao's support, steps onto the nightclub stage as a cross-dressing singer.
