Perhaps you should try some spelling variations:
lang yanling » wang yanling, wang yangming, zhang yunling
yang john » young john, king john, yang jin
yang li » yang lin, yang yi, tang li
yang xi » yang yi, yang jui
ju yang » du yang, yu yang, ju ziyang
bonn am » bonn zum, bonn ana, bonn auf
bonn a » bonn _, bon a, bonn 1

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: lang yanling ((((yang li) OR (yang xi))) OR (yang di)) ju yang john ((bonn am) OR (bonn a)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yanling ((((yang li) or (yang xi))) or (yang di)) ju yang john ((bonn am) OR (bonn a)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yanling ((((yang li) or (yang xi))) or (yang di)) ju yang john ((bonn am) OR (bonn a)) ;*.
