chang run » chang yun, chang hsun, chang ann
chang mae » chang ha, changes made
tan yang » dan yang, tan ying, tan yong

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 yong chang run tan yang jie ((chang mae) OR (hong ghi)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yong chang run tan yang jie ((chang mae) or (hong ghi)) ;*.
