The chef of the restaurant called Cheung Bo was a master of Wing Chun Kung Fu and began teaching him how to defend himself against his assailants. Then in 1941, the famous Yuen Kay Shan owner of great properties in that state and winner of a thousand death fights/combats, asked Cheung's permission to teach Sam some more techniques since he discovered he had talent. But Sam looking at the master’s slim and low physique, doubted his talent and responded that he had nothing to learn from him.
