Perhaps you should try some spelling variations:
wang xiaoping » wang xiaodong, deng xiaoping, wang xiaolin
wang yangming » wang yangming's, wang yanling, wang danning
dan yang » daun yang, wang yang, yang yang
tan yang » tan ying, tan yong, tao yang
min dang » yimin dang, mein dank, bin dann
tan hua » tuan hua, wang hua, tan chia
hai » hadi, haji, hari

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 yangming)) tan hua ((dan yang) OR (tan yang)) min dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang xiaoping) or (wang yangming)) tan hua ((dan yang) OR (tan yang)) min dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang xiaoping) or (wang yangming)) tan hua ((dan yang) OR (tan yang)) min dang hai ;*.
