chang chen » chang ch'un, chang chuan, change when
kang chen » jane chen, kang han, tang chun
yang jie » yang jin, yang di, yang jui
longer a » longer _

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 hyoung gun ((kang chen) OR (chang chen)) yang jie ((long d) OR (longer a)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung gun ((kang chen) OR (chang chen)) yang jie ((long d) or (longer a)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang hyoung gun ((kang chen) OR (chang chen)) yang jie ((long d) or (longer a)) ;*.
