Duncan Leung, a Wing Chun master whose ancestral home is in Zhongshan, recently visited his hometown, Chongkou Village in Zhongshan's Nanlang, with his foreign disciple Stanley Maro Warden. The 82-year-old was trying to answer his disciple's question about the essence of Chinese kung fu.

"Kung fu is a blend of delicacy and force, and culture is a form of soft power," said Duncan Leung. "I teach Chinese kung fu, and at the same time spread Chinese culture to the world."

In the courtyard of Liang's Ancestral Temple, Stanley (front left) and Ko Kwok-cheung, a 68-year-old student from Hong Kong (front right), engage practice offensive and defensive movements in pair, while Duncan is standing aside and providing instructions.
