yi chang » ii chang, ying chang, jin chang
tan ying » fan ying, ran ying, tan yang
ying jin » yang jin, jing ji, yang jie
kang han » kang chen, kong hang, zhang han
eang hay » dang hai
yun tan » yun jang

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 ((yang yang) OR (yi chang)) yun tan ying jin ((kang han) OR (eang hay)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((yang yang) or (yi chang)) yun tan ying jin ((kang han) or (eang hay)) ;*.
