Perhaps you should try some spelling variations:
kang minah » sang minh
yan liang » yang liang, wang liang, you liang
lang yan » wang yan, wang yang, zhang yan
yang jin » yang jie, yang jun, ying jin
gong hui » tong shui, wang hui, gong si
tong hui » wang hui
li kang » li gang, li wang, xi kang

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 yan ((yan liang) OR (yang jin)) li kang minah ((gong hui) OR (tong hui)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan ((yan liang) or (yang jin)) li kang minah ((gong hui) or (tong hui)) ;*.
