Perhaps you should try some spelling variations:
ping john » king john, kong john, wong john
yan guang » yang guang, yan liang, yan wang
gan guan » quan guan, fan guon, gui guan
yan guan » yan yuan, yang guang, yihan guan
ren ping » chen ping, yuen ping, fun ping
wong sam » wong sau, wong lai, von sam
hua ren » hua chen
wang » wing, wan, lang
sar » sara, star, saur

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 guang) OR (gan guan))) OR (yan guan)) hua ren ping john ((wong sam) OR (kong sar)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yan guang) OR (gan guan))) or (yan guan)) hua ren ping john ((wong sam) or (kong sar)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yan guang) OR (gan guan))) or (yan guan)) hua ren ping john ((wong sam) or (kong sar)) ;*.
