Perhaps you should try some spelling variations:
kang minh » kang minah, sang minh, anh minh
yang jie » yang di, yang jui, yang xi
yang jin » yang jun, ying jin, shang jin
cong sun » cong shu, cong van
wing sun » liang sun, nina sun, wing ian
yi kang » xi kang, yi gang, yi yang
wang » wan, lang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ((yang jie) OR (yang jin)) yi kang minh ((cong sun) OR (wing sun)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((yang jie) or (yang jin)) yi kang minh ((cong sun) OR (wing sun)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((yang jie) or (yang jin)) yi kang minh ((cong sun) OR (wing sun)) ;*.
