Perhaps you should try some spelling variations:
wing hyoung » wang hyoung, hwang byoung
min hyoung » min hong, mun young
gun chia » run china, gun his, tan chia
kang hay » eang hay, kang han, dang hai
chia du » china due
yang xi » yang di, yang jui
yang yi » yang di, yang jui

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: ((wing hyoung) OR (min hyoung)) gun chia du ((yang xi) OR (yang yi)) kang hay ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing hyoung) or (min hyoung)) gun chia du ((yang xi) OR (yang yi)) kang hay ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing hyoung) or (min hyoung)) gun chia du ((yang xi) OR (yang yi)) kang hay ;*.
