Perhaps you should try some spelling variations:
hyoung yang » kyoung yang
yang yun » yang jun, tang yun, yang yue
yun gain » run gain, you gain, n gain
kang hay » kang han, dang hai, kang tae
eang hay » dang hai, kang han
yang xi » yang di, yang jui
yang yi » yang di, yang jui
wang » wing, wan

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (wang or lang) hyoung yang yun gain ((yang xi) or (yang yi)) ((kang hay) OR (eang hay)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) hyoung yang yun gain ((yang xi) OR (yang yi)) ((kang hay) OR (eang hay)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) hyoung yang yun gain ((yang xi) or (yang yi)) ((kang hay) OR (eang hay)) ;*".
