Perhaps you should try some spelling variations:
yang yan » yang yang, wang yan, yang yao
yang fan » zhang fan, yang yang, yang jin
yang den » gang der, yang di, yang jin
wong yue » wang yue, hong yu
di rene » di rete, dr rene, i rene
yang li » yang lin, yang di, yang xi
li wong » li cong, li rong, 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 fan) OR (yang dean))))) or (yang den)) di rene yang li wong yue ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yang yan) OR (((yang fan) OR (yang dean))))) OR (yang den)) di rene yang li wong yue ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang yan) or (((yang fan) OR (yang dean))))) or (yang den)) di rene yang li wong yue ;*".
