Once Upon a Time in China (also known as Enter the New Game of Death in the Philippines) is a 1991 Hong Kong biographical martial arts film directed and produced by Tsui Hark, who also wrote with Yuen Kai-chi, Leung Yiu-ming, and Elsa Tang.

Jet Li stars as Chinese martial arts master and folk hero of Cantonese ethnicity, Wong Fei-hung.

The film co-stars Yuen Biao, Jacky Cheung, Rosamund Kwan, and Kent Cheng.

Liu Yongfu, the commander of the Black Flag Army, invites Wong Fei-hung on board his ship to watch a lion dance.

He also runs his own traditional Chinese medicine clinic, Po-chi-lam, and has three apprentices: "Porky Wing", "Bucktooth" So, and Kai.

In the meantime, Leung Foon meets a northern martial artist, "Iron Vest" Yim, and decides to follow him.

In return for protection from the authorities, the Shaho Gang helps Jackson run his underground human trafficking ring by kidnapping Chinese women to be sent to America as prostitutes.

The Governor blames Wong and threatens to arrest and execute him, but allows him to give medical attention to the injured.

Shortly after Yim left, the Governor shows up and orders his men to search Po-chi-lam for fugitives.

At the end of the film, Wong accepts Leung as his fourth apprentice and they take a group photo in Po-chi-lam.
