Perhaps you should try some spelling variations:
wang yong » wang hyoung, wang yan, wang shiyong
wang yang » wang yan, wang liang, wang yanling
sang minh » kang minah, anh minh, song min
yang lin » yang jin, wang lin, yang liang
wong sam » wong sau, wong lai, kong sar
yang li » yang di, yang xi, yang yi
tang » tan, lang, gang

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) OR (wang yang)) ((yang lin) OR (yang li)) ju ((tang li) OR (sang minh)) wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) OR (wang yang)) ((yang lin) OR (yang li)) ju ((tang li) OR (sang minh)) wong sam ;*.
