Perhaps you should try some spelling variations:
wang kyoung » wang hyoung, hwang byoung, wang yong
gain yang » dan yang, daun yang, tan yang
yang jui » yang judy, yang di
kang hay » kang han, dang hai, kang tae
eang hay » dang hai, kang han
yang xi » yang di
yang yi » yang di

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 kyoung ((yang jui) OR (yang xi)) gain yang yi ((kang hay) OR (eang hay)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang kyoung ((yang jui) OR (yang xi)) gain yang yi ((kang hay) or (eang hay)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang kyoung ((yang jui) OR (yang xi)) gain yang yi ((kang hay) or (eang hay)) ;*.
