Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
wang yong » wang hyoung, wang yan, wang shiyong
yang jin » yang jie, yang jun, ying jin
di rene » dr rene, i rene, ii rene
yang li » yang lin, yang di, yang xi
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.

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