Perhaps you should try some spelling variations:
wang wang » wang liang, wang yan, wang yong
wang yang » wang yan, wang liang, wang yanling
chang min » zhang ming, chang mae, chang ann
chan ming » kian ming, chan eng, chan fong
tang min » sang minh, yang mind, tang li
wong sam » wong sau, wong lai, kong sar
li liu » liu liu, li lin, li lu
li li » li lin, li l, li lu

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 wang yang ((li liu) OR (li li)) ((tang min) OR (((chang min) OR (chan ming)))) wong sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang yang ((li liu) or (li li)) ((tang min) or (((chang min) OR (chan ming)))) wong sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang yang ((li liu) or (li li)) ((tang min) or (((chang min) OR (chan ming)))) wong sam ;*.
