Perhaps you should try some spelling variations:
wang yong » wang yang, wang hyoung, wang yan
yuan gain » run gain, yuan kai
yong yan » yang yang, dong yang, ying yang
kang hay » eang hay, dang hai, kang tae
kang han » kang chen, kong hang, zhang han
yuan lin » yuan li, duan lian, huang lin
tan kah » tan ah, tan kai
yang wu » yang du, yang mu, yang jui

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