Perhaps you should try some spelling variations:
wang manning » wang danning, wang yanling, wang yangming
yang amin » yang jin, yang lin, yang mind
zhong tai » hong tan, zhong zhi
tony hua » tony a, tony h, dong hua
tong hui » wang hui
dan yang » daun yang, tan yang, wang yang
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 manning ((tony hua) OR (tong hui)) dan yang amin ((hong hai) OR (zhong tai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang manning ((tony hua) or (tong hui)) dan yang amin ((hong hai) OR (zhong tai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang manning ((tony hua) or (tong hui)) dan yang amin ((hong hai) OR (zhong tai)) ;*.
