Perhaps you should try some spelling variations:
changed dang » change data, changed a, changed east
yang yang » wang yang, wang yan
ka chuan » say chuan, hai chuan, ka chai
bang has » bang case, bang dai, bang how
bank has » bank days, bank hard, bank a
dong di » dong sin
hai » hadi, haji, hari

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: ((yang yang) OR (dong di)) ((ya hua) OR (ka chuan)) ((bang has) OR (bank has)) changed dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (dong di)) ((ya hua) or (ka chuan)) ((bang has) OR (bank has)) changed dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang yang) or (dong di)) ((ya hua) or (ka chuan)) ((bang has) OR (bank has)) changed dang hai ;*.
