Perhaps you should try some spelling variations:
xiaoping than » xiaoping how, xiaoping shi
than china » tuan china, han china, wuhan china
fund data » wind data
tan yang » dan yang, tan ying, tao yang
tan yong » tan hong, tan ying, wang yong
tan kong » tan hong
deng » den, eng, dung

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: deng xiaoping than china ((tan yang) OR (((tan yong) OR (tan kong)))) fund data (hai OR hari) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "deng xiaoping than china ((tan yang) or (((tan yong) OR (tan kong)))) fund data (hai or hari) ;~".
• Adding a wildcard symbol may retrieve word variants: deng xiaoping than china ((tan yang) or (((tan yong) OR (tan kong)))) fund data (hai or hari) ;*.
