Perhaps you should try some spelling variations:
wang danning » wang yanling, wang daoping, wang yangming
china data » china update, chinese data
china dan » china den, china des, china due
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 dan) OR (china data)) yang jun kang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang danning yunnan ((china dan) OR (china data)) yang jun kang hai ;*.
