Perhaps you should try some spelling variations:
wang xiaoping » deng xiaoping, wang xiaolin, huang xiaoting
shang hai » shang kai, dang hai, chang ha
tuan hua » tan hua, tuan vu, yuan hui
ban yang » dan yang, tan yang, wang yang
yang lin » yang jin, wang lin, yang li
hong hai » zhong tai, 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 xiaoping) OR (wang xiaodong)) tuan hua ban yang lin ((hong hai) OR (shang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang xiaoping) or (wang xiaodong)) tuan hua ban yang lin ((hong hai) OR (shang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang xiaoping) or (wang xiaodong)) tuan hua ban yang lin ((hong hai) OR (shang hai)) ;*.
