Perhaps you should try some spelling variations:
wang tan » wang yan, wang ban, wang tao
wang dan » wang yan, wang ban, wang yidan
tang min » chang min, sang minh, yang mind
wong siu » wong shiu, kong siu, wong sau
yang xi » yang di, yang yi, yang jui
wu tang » wu kang, wu guang
xi wu » yi wu, li wu, xi bu

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 tan) OR (wang dan)) yang xi wu tang min ((wong siu) OR (cong shu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang tan) OR (wang dan)) yang xi wu tang min ((wong siu) or (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang tan) OR (wang dan)) yang xi wu tang min ((wong siu) or (cong shu)) ;*.
