Perhaps you should try some spelling variations:
wang kyoung » wang hyoung, hwang byoung, wang yong
yihan guan » yan guan
yang guang » yang yang, yan guan, yang liang
gain yang » dan yang, daun yang, yin yang
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 ((yihan guan) OR (yang guang)) ((gain yang) OR (tan yang)) wu kang hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang kyoung ((yihan guan) or (yang guang)) ((gain yang) OR (tan yang)) wu kang hay ;~".
• Adding a wildcard symbol may retrieve word variants: wang kyoung ((yihan guan) or (yang guang)) ((gain yang) OR (tan yang)) wu kang hay ;*.
