Perhaps you should try some spelling variations:
yan change » can change, mean change, man changed
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
dong di » dong sin
how hai » how has, how ai, how hci

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 change how hai ;~.
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (dong di)) ((ya chuan) or (ka chuan)) bang yan change how hai ;*.
