Perhaps you should try some spelling variations:
john wong » john song, john bonn
yang lin » yang jin, wang lin, yang li
yang jui » yang judy, yang di, yang xi
wong sau » wong sam, wong siu, wong shiu
wan yan » wang yan, nan yan, wai yan
lu ying » li ying, lu ding, lu yilong
lu xing » le xing, lu ding, lu xin
ku ying » ka ying, ku ring, hui ying

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan yan ((yang lin) or (yang jui)) ((((lu ying) OR (lu xing))) or (ku ying)) john wong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((yang lin) OR (yang jui)) ((((lu ying) OR (lu xing))) OR (ku ying)) john wong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((yang lin) or (yang jui)) ((((lu ying) OR (lu xing))) or (ku ying)) john wong sau ;*".
