Perhaps you should try some spelling variations:
kann eine » kann ein, dann einen, kann die
wong john » wrong john, kong john, longo john
zhang si » zhang i, zhang li, zhang yi
zhang ii » zhang i, zhang li, zhang yi
how wong » how long, how hong, how wood
bonn ein » bonn mein, bonn die, kann ein
yang yi » yang xi, 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 si) OR (zhang ii)) ((yang di) OR (yang yi)) how wong john ((bonn ein) OR (kann eine)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((zhang si) OR (zhang ii)) ((yang di) or (yang yi)) how wong john ((bonn ein) or (kann eine)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((zhang si) OR (zhang ii)) ((yang di) or (yang yi)) how wong john ((bonn ein) or (kann eine)) ;*.
