Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
yang yan » wang yan, yang fan, yang yao
yang den » yang dean, gang der, yang di
rong yue » wong yue, rong yu, hong yu
di rene » di rete, dr rene, i rene
yang li » yang lin, yang di, yang xi
li rong » yi rong, li cong, li song

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((((yang yan) OR (yang yang))) or (yang den)) di rene yang li rong yue ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yang yan) OR (yang yang))) OR (yang den)) di rene yang li rong yue ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang yan) OR (yang yang))) or (yang den)) di rene yang li rong yue ;*".
