Perhaps you should try some spelling variations:
juan rene » juan meng, juan rana
hua rene » hua ren
tang tin » tang tang, ting ting, tang li
tang min » chang min, sang minh, yang mind
hong shu » cong shu, tong shui, wong shiu
yan yan » yan yuan, nan yan, yang yang
wang » wing, wan, lang

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 yan yan ((hua rene) OR (juan rene)) ((tang tin) OR (tang min)) hong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yan ((hua rene) OR (juan rene)) ((tang tin) or (tang min)) hong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yan ((hua rene) OR (juan rene)) ((tang tin) or (tang min)) hong shu ;*.
