Perhaps you should try some spelling variations:
wang yangming » wang yangming's, wang yanling, wang danning
brief john » brian john
der brief » der briefe, de brief, very brief
john wong » john song, john bonn
wong star » lone star, wong sam, wong sau
yang jie » yang jin, yang xi, yang yi
yang jui » yang judy, yang xi, yang yi

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 yangming ((((yang jie) OR (yang jui))) OR (yang di)) der brief john wong star ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yangming ((((yang jie) OR (yang jui))) or (yang di)) der brief john wong star ;~".
• Adding a wildcard symbol may retrieve word variants: wang yangming ((((yang jie) OR (yang jui))) or (yang di)) der brief john wong star ;*.
