Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
hong hong » hong kong, hong jong, hong ng
yang yan » wang yan, yang fan, yang yao
wie rene » wilke rene, wie deine, wie eine
pang can » pang jun, lung can
pang kin » pang jun, kang kim, pang jiu
kang ca » kang tae, kang han

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 yan) OR (yang yang)) wie rene ((((pang can) OR (pang kin))) OR (kang ca)) hong hong ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang yan) OR (yang yang)) wie rene ((((pang can) or (pang kin))) or (kang ca)) hong hong ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang yan) OR (yang yang)) wie rene ((((pang can) or (pang kin))) or (kang ca)) hong hong ;*.
