Perhaps you should try some spelling variations:
ruan wing » yuan wang
kim doing » kim dong, kind doing, kim young
doing von » doing un, ing von
yang tan » yang yang, liang tan, tang tang
yang fan » zhang fan, yang yang, yang jin
wing tan » wing ian, liang tan, hong tan
dean » dewan, jean, den

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 ((((yang tan) OR (yang fan))) OR (yang dean)) ruan wing tan kim doing von ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang tan) OR (yang fan))) or (yang dean)) ruan wing tan kim doing von ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yang tan) OR (yang fan))) or (yang dean)) ruan wing tan kim doing von ;*.
