Perhaps you should try some spelling variations:
kang minah » sang minh
gang minh » sang minh, anh minh, gong min
lang yan » wang yan, wang yang, zhang yan
yang lin » yang jin, wang lin, yang li
tong hui » wang hui
yang xi » yang di, yang yi, yang jui
long du » long d, long do, long run

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: lang yan ((yang lin) or (yang xi)) xu ((gang minh) OR (kang minah)) ((long du) or (tong hui)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang yan ((yang lin) OR (yang xi)) xu ((gang minh) OR (kang minah)) ((long du) OR (tong hui)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((yang lin) or (yang xi)) xu ((gang minh) OR (kang minah)) ((long du) or (tong hui)) ;*".
