Perhaps you should try some spelling variations:
wang xiaobing » wang xiaodong, wang xiaolin, huang xiaoting
wang xiaoping » wang xiaodong, deng xiaoping, wang xiaolin
thanh vu » thanh van, thanh _
tan yong » tan hong, tan kong, tan yang
min hong » amin hong, tin hong, min hyoung
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 xiaobing) OR (wang xiaoping)) thanh vu ((du yang) OR (tan yong)) min hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang xiaobing) OR (wang xiaoping)) thanh vu ((du yang) or (tan yong)) min hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang xiaobing) OR (wang xiaoping)) thanh vu ((du yang) or (tan yong)) min hong hai ;*.
