tan yang » dan yang, tan ying, tan yong
yang jie » yang jin, yang di, yang jui
jie kang » jin kang, jie zhang, wie kann
yan run » can run, bank run, yan guan
yan kun » yan guan, yan yuan
tae » take, tape, tale

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 zhang ((yan run) OR (yan kun)) tan yang jie kang tae ;~.
• Adding a wildcard symbol may retrieve word variants: wang zhang ((yan run) or (yan kun)) tan yang jie kang tae ;*.
