Perhaps you should try some spelling variations:
yang yala » yang yang, yang all, yang dali
yang yao » yang yang, wang yan, yang yi
hua rene » hua ren, juan rene
rene yan » ren yan, rene ten, see yan
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
yan jiu » yang jie, yang jin, pang jiu

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 ((yang yala) OR (yang yao)) hua rene yan jiu ((hong ghi) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang yala) OR (yang yao)) hua rene yan jiu ((hong ghi) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang yala) OR (yang yao)) hua rene yan jiu ((hong ghi) or (hong hai)) ;*.
