Cheung eventually moved to Hong Kong. He opened a martial arts studio and became the head teacher to the Hong Kong Hakka ship and dock workers union. The classes in Hong Kong was taught by Wong Yook-Kong and this school still exists today. Wong Yook-Kong was described as a large man and in training he placed great emphasis on strength and physical conditioning before moving onto the more internal aspects of the style. One of his favorite training method was to practise with 30 to 60 LB iron rings on his wrist while he perform his forms. As a result, his students also emphasize those aspects in their training. The lineage of Wong Yook Kong is continued by his two sons: Wong Yiu Hung () and Wong Yiu Hwa () and other students such as Lee Kwok Leung, () and Sifu John Koo of Portland, Oregon, a Disciple of both Wong Yook-Kong and Lee Wing Sing.
