Perhaps you should try some spelling variations:
wang danning » wang yanling, wang daoping, wang yangming
yunnan china » urban china, tuan china, wuhan china
china dan » china den, china data, china des
dan yang » daun yang, tan yang, wang yang
yang jun » yang jui, pang jun, yang jin
kang hai » kang han, shang hai, kang tae

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang danning yunnan china dan yang jun ((kang hai) OR (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang danning yunnan china dan yang jun ((kang hai) OR (dang hai)) ;*.
