Perhaps you should try some spelling variations:
hyoung yan » hyoung gun, kyoung yun, young yun
yuan gain » run gain, yuan kai, yuan lin
kang hay » eang hay, kang han, dang hai
tan kah » tan ah, tan kai
yang wu » yang du, yang mu, yang jui
wu kang » wu guang
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 ((hyoung yan) OR (kyoung yang)) ((yuan gain) OR (tan kah)) yang wu kang hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((hyoung yan) OR (kyoung yang)) ((yuan gain) or (tan kah)) yang wu kang hay ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((hyoung yan) OR (kyoung yang)) ((yuan gain) or (tan kah)) yang wu kang hay ;*.
