Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
lang yan » wang yan, wang yang, zhang yan
yang jie » yang jin, yang di, yang xi
yang jui » yang judy, yang di, yang xi
san minh » tuan minh, anh minh, kan min
tong hui » wang hui
han min » han men, kan min, chan ming

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((yang jie) OR (yang jui)) di ((((san minh) OR (han min))) OR (sang minh)) tong hui ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((yang jie) OR (yang jui)) di ((((san minh) OR (han min))) OR (sang minh)) tong hui ;*.
