Perhaps you should try some spelling variations:
yang yaong » yang yang, wang yang, wang yong
juan rene » juan meng, juan rana
yaong ya » yang yao
hua rene » hua ren
yang min » yang mind, yang jin, tang min
hong shu » cong shu, tong shui, wong shiu
hong ghi » zhong zhi, hong g, hong hai

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