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
di rene » dr rene, i rene, ii rene
yang li » yang lin, yang di, yang xi
li hong » le hong, li cong, li rong
hong yu » wong yue
rete » crete, grete, rente

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) OR (di rete)) yang li hong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yang yan) OR (yang yang))) OR (yang den)) ((di rene) OR (di rete)) yang li hong yu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang yan) or (yang yang))) or (yang den)) ((di rene) OR (di rete)) yang li hong yu ;*".
