Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang mind » yang cindy, yang jin, tang min
sang minh » kang minah, anh minh, song min
zhong tai » hong tan, zhong zhi
yang fan » zhang fan, yang dean, yang yang
shi jian » shi japan, shi lin, shi dan
hong hai » shang hai, dang hai, hong tan

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 fan shi jian ((yang mind) OR (sang minh)) ((hong hai) OR (zhong tai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang fan shi jian ((yang mind) OR (sang minh)) ((hong hai) or (zhong tai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang fan shi jian ((yang mind) OR (sang minh)) ((hong hai) or (zhong tai)) ;*.
