Perhaps you should try some spelling variations:
wang xiaoping » wang xiaodong, deng xiaoping, wang xiaolin
wang xiaoyi » wang xiaolin, wang xiaozu, wang xiaobing
huang chang » huang cheng, hoong chang, huang yang
chuan chuan » chen chuan, chang chuan
chung chuan » chen chuan
hong hong » hong kong, hong jong, hong ng
hong hai » shang hai, zhong tai, dang hai

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 xiaoyi) OR (wang xiaoping)) huang chang ((chuan chuan) OR (chung chuan)) hong hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang xiaoyi) OR (wang xiaoping)) huang chang ((chuan chuan) or (chung chuan)) hong hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang xiaoyi) OR (wang xiaoping)) huang chang ((chuan chuan) or (chung chuan)) hong hong hai ;*.
