Perhaps you should try some spelling variations:
gang minh » sang minh, kang minah, anh minh
tong shui » tong hui, cong shu, gong hui
lang yan » wang yan, wang yang, zhang yan
long shu » cong shu
yang li » yang lin, yang di, yang yi
yang xi » yang di, yang yi, yang jui
xu gang » yu gang, zum gang, liu gang
long du » long d, long do, long run

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 ((yang li) OR (yang xi)) xu gang minh ((((long shu) OR (long du))) OR (tong shui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan ((yang li) or (yang xi)) xu gang minh ((((long shu) OR (long du))) or (tong shui)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan ((yang li) or (yang xi)) xu gang minh ((((long shu) OR (long du))) or (tong shui)) ;*.
