Perhaps you should try some spelling variations:
hyoung yan » kyoung yang, hyoung gun, kyoung yun
t'an yang » tan yang, dan yang, tao yang
guang han » kang han
zhang han » zhang fan, zhang yan, zhang hanmo
yan huan » yan guan, yan yuan, tan hua
yang wu » yang du, yang mu, yang jui
wang » 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 OR wing) hyoung yan huan t'an yang wu ((guang han) OR (zhang han)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) hyoung yan huan t'an yang wu ((guang han) OR (zhang han)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) hyoung yan huan t'an yang wu ((guang han) OR (zhang han)) ;*.
