Perhaps you should try some spelling variations:
thang long » change long
yan thang » yan zhang, xuan thang, yuan chang
dong nan » dong yang, dong sin, dong bin
ya chuan » say chuan, hai chuan, ya hua
ka chuan » say chuan, hai chuan, ka chai
bang yan » wang yan, wang yang, zhang yan
long hai » hong hai, long han, long chain
dong di » dong sin

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: ((dong nan) OR (dong di)) ((ya chuan) OR (ka chuan)) bang yan thang long hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (dong di)) ((ya chuan) OR (ka chuan)) bang yan thang long hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (dong di)) ((ya chuan) OR (ka chuan)) bang yan thang long hai ;*.
