Perhaps you should try some spelling variations:
wang danning » wang yanling, wang daoping, wang yangming
yunnan china » urban china, tuan china, yunnan sheng
wuhan china » tuan china
data yang » apa yang
yang jun » yang jui, pang jun, yang jin
jun kang » jin kang, yuan kang, wu kang
kang hai » dang hai, kang han, shang hai

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) OR (wuhan china)) data yang jun kang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang danning ((yunnan china) OR (wuhan china)) data yang jun kang hai ;*.
