Perhaps you should try some spelling variations:
wang hyong » wang hyoung, wang heyong, wang hong
yihan guan » yan guan
yang guang » yang yang, yan guan, yang liang
wang yong » wang yang, wang hyoung, wang yan
gain yang » dan yang, daun yang, tan yang
yang jui » yang judy, yang di, yang xi
jui kang » jin kang, jui meng, wu kang
kang hay » eang hay, kang han, dang hai

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