Perhaps you should try some spelling variations:
hyoung gan » young man
hyoung gun » young eun
guan tan » huan t'an, tan tan
tan yong » tan hong, tan kong, tan yang
yong jui » yang jui, yang jun, yong cai
jui kang » jin kang, jui meng, wu kang
kang han » kang chen, kong hang, zhang han

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: (wan OR wing) ((hyoung gan) OR (hyoung gun)) guan tan yong jui kang han ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wan or wing) ((hyoung gan) OR (hyoung gun)) guan tan yong jui kang han ;~".
• Adding a wildcard symbol may retrieve word variants: (wan or wing) ((hyoung gan) OR (hyoung gun)) guan tan yong jui kang han ;*.
