Perhaps you should try some spelling variations:
bonn mein » bonn ein
wong john » wrong john, kong john, longo john
how wong » how long, how hong, how wood
zhang ii » zhang i, zhang li, zhang si
bonn die » kann die, wenn die
kann ein » kann eine, kann die, kann man
yang xi » yang di, yang jui
yang yi » yang di, yang jui

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: zhang ii ((yang xi) OR (yang yi)) how wong john ((((bonn mein) OR (bonn die))) OR (kann ein)) ;~.
• Adding a wildcard symbol may retrieve word variants: zhang ii ((yang xi) or (yang yi)) how wong john ((((bonn mein) or (bonn die))) or (kann ein)) ;*.
