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

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 si ((yang di) OR (((yang yi) OR (yang jui)))) how wong john ((bonn ein) OR (kann ein)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang si ((yang di) or (((yang yi) OR (yang jui)))) how wong john ((bonn ein) or (kann ein)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang si ((yang di) or (((yang yi) OR (yang jui)))) how wong john ((bonn ein) or (kann ein)) ;*.
