Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang july » yang judy, yang jui, yang jun
yan guan » gan guan, yan yuan, yang guang
guan run » can run
run pain » run gain
yang lin » yang jin, wang lin, yang li
wei yan » wei yang, wei yuan, wai yan
dang » dan, lang, dans
hai » hadi, haji, hari

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: wei yan guan run pain ((((wang yang) OR (((yang lin) OR (yang di))))) OR (yang july)) dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wei yan guan run pain ((((wang yang) or (((yang lin) or (yang di))))) or (yang july)) dang hai ;*.
