Perhaps you should try some spelling variations:
how young » how you
how your » how you, grow your, know your
bonn ein » bonn mein, bonn die, bonn iii
kann ein » kann eine, kann die, kann man
zhang i » zhang ii, zhang li, zhang si
yang li » yang lin, yang di, yang xi
yang yi » yang di, 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 i ((yang li) OR (yang yi)) ((how young) OR (how your)) john ((bonn ein) OR (kann ein)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang i ((yang li) or (yang yi)) ((how young) OR (how your)) john ((bonn ein) or (kann ein)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang i ((yang li) or (yang yi)) ((how young) OR (how your)) john ((bonn ein) or (kann ein)) ;*.
