Movies like the king of masks

The King of Masks (simplified Chinese: 变脸; traditional Chinese: 變臉; pinyin: Biàn Liǎn) is a 1996 Chinese film directed by Wu Tianming.

In 1930's China, Wang is The King of Masks, an aged street performer who practices the change-mask opera art of bian lian. He laments that he has no male heirs to carry on his mysterious and complicated art and trade. At an illegal child market, Wang buys what he believes to be an orphan boy to become his adopted grandson and apprentice.

However, Wang soon learns his new disciple is in fact a girl. As tradition dictates that he cannot pass his art onto a girl, he tries to abandon her, but she stubbornly stays with him. He later calls her "doggie" and has her refer to him as "boss". He then begins to train her to be a flexible contortionist street performer. While looking at his masks, she accidentally sets his humble residence on fire. Out of guilt, she runs away. She is then captured by two men and held in a room with a boy to be sold later. Doggie helps the boy escape and takes him to Wang to have as a grandson.
