Dennis Law Chun-hung's generation may well be the last to learn the twin skills of Chinese martial arts and bone-setting from their fathers or kung fu teachers.
Traditionally, people who studied kung fu were required to also learn bone-setting, so they could treat the injuries that came with martial arts. Like China's other healing skills, the techniques were passed from master to disciple or parent to child.
That custom ended in Hong Kong when in 2003 the government tightened regulations on traditional medicine to make the industry more professional.
Both Dennis, 50, and his older brother, Law Chun-chiu, acquired the know-how from their father before inheriting his bone-setting and massotherapy house in Wan Chai two decades ago. Two years ago, Dennis founded his own shop nearby.
Dennis' father, Law Kwok-wai, was born in 1917 to a farming family in Guangdong, where he learned hung kuen, a type of boxing popular in southern China, and the methods to treat the resulting bruises.
After moving to Hong Kong in the 1950s, Law Kwok-wai toiled in a laundry to support his six children but at night he taught children kung fu and treated neighbours with injuries.
