Perhaps you should try some spelling variations:
wang danning » wang daoping, wang yangming, wang ning
china data » china update, chinese data
china dan » china den, china des, china due
yang jin » yang jie, yang jun, ying jin
jin hong » tin hong, jin song, min hong
hong hai » shang hai, zhong tai, dang hai

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: ((wang danning) OR (wang yanling)) tuan ((china dan) OR (china data)) yang jin hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang danning) or (wang yanling)) tuan ((china dan) OR (china data)) yang jin hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang danning) or (wang yanling)) tuan ((china dan) OR (china data)) yang jin hong hai ;*.
