One-Armed Boxer (獨臂拳王) is a 1972 Hong Kong wuxia film directed, written by and starring Jimmy Wang Yu.
Produced by Raymond Chow, it was released in 1972 in Hong Kong and various countries, and in late 1973 in the United States under a new title, The Chinese Professionals.
The Hook Gang are part of a local opium-dealing and prostitution ring run by a man named Chao and are rivals of the Ching Te school.
The Ching Te school is the most prominent martial arts academy in town and controls the local clothes-dyeing and brick factories.
After escaping the massacre at the school, Tien Lung flees and is eventually rescued by a woman named Jade and her father, who happens to be a specialist in medicine.
