Perhaps you should try some spelling variations:
yang jean » yang dean, young jean, yang jin
yang yan » yang yang, wang yan, yang yao
yang fan » zhang fan, yang dean, yang yang
di rene » dr rene, i rene, ii rene
yang xi » yang di, yang yi, yang jui
xi rong » yi rong, li rong, shi rong
rong yu » hong yu, rong su, wong yue
rete » crete, grete, rente

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 fan))) OR (yang jean)) ((di rene) OR (di rete)) yang xi rong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang yan) or (yang fan))) or (yang jean)) ((di rene) OR (di rete)) yang xi rong yu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yang yan) or (yang fan))) or (yang jean)) ((di rene) OR (di rete)) yang xi rong yu ;*.
