Perhaps you should try some spelling variations:
chan kang » chung kang, chan jan, chan ming
chan fong » chew fong, chan ming
wong shiu » wong siu, cong shu, song shin
yu cheng » yu chen, _ cheng
jui chen » yi chen
chan eng » chan ming, han en, tan eng
yan ka » yang ka, yuan kai
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang yan ka ((yu cheng) or (jui chen)) ((((chan eng) OR (chan kang))) or (chan fong)) wong shiu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan ka ((yu cheng) OR (jui chen)) ((((chan eng) OR (chan kang))) OR (chan fong)) wong shiu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ka ((yu cheng) or (jui chen)) ((((chan eng) OR (chan kang))) or (chan fong)) wong shiu ;*".
