Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yuan gain » run gain, yuan kai, yuan lin
guang hay » eang hay
yong yan » yang yang, dong yang, ying yang
yang jui » yang judy, yang xi, yang yi
tan kah » tan ah, tan kai
yang wu » yang du, yang mu, yang jun

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 yong yan ((yuan gain) OR (tan kah)) ((yang wu) OR (((yang jui) OR (yang di)))) guang hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yan ((yuan gain) or (tan kah)) ((yang wu) or (((yang jui) OR (yang di)))) guang hay ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yan ((yuan gain) or (tan kah)) ((yang wu) or (((yang jui) OR (yang di)))) guang hay ;*.
