Perhaps you should try some spelling variations:
wong john » wrong john, kong john, longo john
how wong » how long, how hong, how wood
bonn ein » bonn mein, bonn die, bonn iii
kann ein » kann eine, kann man
zhang i » zhang ii, zhang li, zhang si
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 i ((yang xi) OR (yang yi)) how wong john ((((bonn ein) OR (kann die))) OR (kann ein)) ;~.
• Adding a wildcard symbol may retrieve word variants: zhang i ((yang xi) or (yang yi)) how wong john ((((bonn ein) or (kann die))) or (kann ein)) ;*.
