yang yang » wang yang, wang yan
king tan » king dan, wing tan, liang tan
tan yong » tan hong, tan kong, tan yang
kang hay » eang hay, kang han, kang tae
yong wu » yong suk, yong wah
hai » hadi, haji, hari

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 yang) OR (yang yang)) king tan yong wu ((kang hay) OR (dang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((yong yang) or (yang yang)) king tan yong wu ((kang hay) or (dang hai)) ;*.
