Perhaps you should try some spelling variations:
wang liang » wang yang
ying john » king john, young john, ying jin
bonn sau » bonn a, bonn am, bonn das
bonn auf » bonn zur, bonn zum, bonn a
yang xi » yang di, yang yi, yang jui
l ying » li ying, _ ying
xi l » xu l, i l, 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: ((wang yanling) OR (wang liang)) yang xi l ying john ((bonn sau) OR (bonn auf)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yanling) or (wang liang)) yang xi l ying john ((bonn sau) OR (bonn auf)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yanling) or (wang liang)) yang xi l ying john ((bonn sau) OR (bonn auf)) ;*.
