Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
tuan hua » yuan hui
yang jui » yang judy, yang di, yang yi
kang han » kang chen, kong hang, zhang han
tan hua » wang hua, tan chia, tan puay
tuan vu » thanh vu
yang xi » yang di, yang yi

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))) OR (tuan vu)) yao ((yang jui) OR (yang xi)) kang han ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung ((((tan hua) or (tuan hua))) or (tuan vu)) yao ((yang jui) OR (yang xi)) kang han ;~".
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((((tan hua) or (tuan hua))) or (tuan vu)) yao ((yang jui) OR (yang xi)) kang han ;*.
