Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang mind » yang cindy, yang jin, sang minh
chang min » zhang ming, chang mae, chan ming
yang xie » yang xi, yang jie, yang di
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
test » text, west, best

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 xie hua (rent OR test) ((yang mind) OR (chang min)) ((hong ghi) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang xie hua (rent or test) ((yang mind) or (chang min)) ((hong ghi) OR (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang xie hua (rent or test) ((yang mind) or (chang min)) ((hong ghi) OR (hong hai)) ;*.
