Perhaps you should try some spelling variations:
lang yanling » wang yanling, wang yangming, zhang yunling
china dan » china data, china des, china due
china den » chinas den, china des, china does
jun chang » jin chang, joon chang, yuan chang
chang hai » chang ha, shang hai, change has
yang jun » yang jui, pang jun, yang jin

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: "lang yanling than ((china dan) OR (china den)) yang jun chang hai ;~".
• Adding a wildcard symbol may retrieve word variants: lang yanling than ((china dan) OR (china den)) yang jun chang hai ;*.
