Perhaps you should try some spelling variations:
young john » kong john, wong john, young jean
how young » how you, how your
yang jui » yang judy, yang yi
bonn ein » bonn mein, bonn die, kann ein
zhang i » zhang ii, zhang li, zhang si
yang li » yang lin, yang yi, tang li
yang xi » yang yi

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