Perhaps you should try some spelling variations:
wang yong » wang hyoung, wang yan, wang shiyong
wang yang » wang yan, wang liang, wang yanling
zhang xue » zhang joe, zhang xin, zhang hui
wang xue » wang yue, wang xuan, wang hua
di rene » dr rene, i rene, ii rene
hong 7 » hong w, hong a, hong g
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 yong) OR (wang yang)) yan ((di rene) OR (di rete)) ((wang xue) OR (zhang xue)) hong 7 ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) or (wang yang)) yan ((di rene) or (di rete)) ((wang xue) OR (zhang xue)) hong 7 ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) or (wang yang)) yan ((di rene) or (di rete)) ((wang xue) OR (zhang xue)) hong 7 ;*.
