Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
von schul » von schule, von schulen, von schuler
yang lin » yang jin, wang lin, yang liang
tang min » chang min, sang minh, yang mind
wong siu » wong shiu, kong siu, wong sau
yang li » yang di, yang xi, yang yi
ii tang » ii taming, ii trans

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 yong ((yang li) OR (yang lin)) ii tang min ((wong siu) OR (von schul)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong ((yang li) or (yang lin)) ii tang min ((wong siu) or (von schul)) ;*.
