Perhaps you should try some spelling variations:
juan rene » juan meng, juan rana
hua rene » hua ren
yang jie » yang jin, yang di, yang jui
hong shu » cong shu, tong shui, wong shiu
yan jiu » yang jin, pang jiu
hong yu » wong yue
dong » doing, long, done
sin » sign, sind, skin

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: dong sin ya ((hua rene) OR (juan rene)) ((yan jiu) OR (yang jie)) ((hong shu) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong sin ya ((hua rene) OR (juan rene)) ((yan jiu) or (yang jie)) ((hong shu) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong sin ya ((hua rene) OR (juan rene)) ((yan jiu) or (yang jie)) ((hong shu) or (hong yu)) ;*.
