Perhaps you should try some spelling variations:
yang john » young john, king john, yang jin
hua chen » jui chen, yu chen, a chen
yan yuan » yan guan, fang yuan, nan yan
bonn sam » bonn am, bonn zum, bonn a
yang yi » yang di, yang xi, yang jui
yan ya » nan ya, yang yao
wang » wing, wan, lang

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 ((((yan ya) OR (yan yuan))) OR (yang yi)) ((hua ren) OR (hua chen)) yang john bonn sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yan ya) or (yan yuan))) or (yang yi)) ((hua ren) OR (hua chen)) yang john bonn sam ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yan ya) or (yan yuan))) or (yang yi)) ((hua ren) OR (hua chen)) yang john bonn sam ;*.
