Perhaps you should try some spelling variations:
wang kyoung » wang hyoung, hwang byoung, kang young
wang yong » wang yang, wang hyoung, wang yan
gain yang » dan yang, daun yang, yin yang
yun guan » yan guan, quan guan, gan guan
tan yang » dan yang, tan ying, tan yong
kang hay » eang hay, kang han, dang hai
wu kang » wu guang

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