Perhaps you should try some spelling variations:
yang yong » wang yong, yang yang, kang young
kim chai » ka chai
chai tan » chai tam, chai onn
tan yong » tan hong, tan kong, tan yang
yong jin » yang jin, ying jin, song jin
hong hai » shang hai, zhong tai, dang hai
chang ha » chang mae

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: yang yong kim chai tan yong jin ((hong hai) OR (chang ha)) ;~.
• Adding a wildcard symbol may retrieve word variants: yang yong kim chai tan yong jin ((hong hai) or (chang ha)) ;*.
