Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
tuan hua » tuan vu, yuan hui
yao yang » yang yang
kang hay » eang hay, kang han, dang hai
tan hua » wang hua, tan chia, tan puay
yang xi » yang di, yang yi, yang jui
xi kang » jin kang, xi zhang

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: lang hyoung ((tan hua) OR (tuan hua)) yao yang xi kang hay ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((tan hua) or (tuan hua)) yao yang xi kang hay ;*.
