Perhaps you should try some spelling variations:
wang danning » wang yanling, wang daoping, wang yangming
yunnan china » urban china, tuan china, wuhan china
china data » china update, chinese data
shang kai » shang hai
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang di, yang xi

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