Perhaps you should try some spelling variations:
chang ch'un » chang hsun
chang chuan » chung chuan, chen chuan
kyoung yun » young yun, kyoung yang, hyoung gun
chang chen » change when, chang hee, kang chen
tan yang » dan yang, tan ying, tan yong
yang jie » yang jin, yang di, yang jui
yun tan » yun jang
tan tan » tas tan, tin tan, tang tang

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: (lang OR wing) kyoung yun tan tan yang jie ((((chang chen) OR (chang ch'un))) OR (chang chuan)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(lang or wing) kyoung yun tan tan yang jie ((((chang chen) OR (chang ch'un))) or (chang chuan)) ;~".
• Adding a wildcard symbol may retrieve word variants: (lang or wing) kyoung yun tan tan yang jie ((((chang chen) OR (chang ch'un))) or (chang chuan)) ;*.
