Perhaps you should try some spelling variations:
than death » than data
dong yang » dong hoang, wang yang, yang yang
than daun » than bau, than daem, than data
yang yao » yang yang, wang yan, yang yi
yang aid » yang anda, yang mind, yang di
how ai » how aid, how ae, how asia
how am » how ae

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 yang yao ((than daun) OR (than death)) yang aid ((how ai) OR (how am)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang yao ((than daun) or (than death)) yang aid ((how ai) OR (how am)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang yao ((than daun) or (than death)) yang aid ((how ai) OR (how am)) ;*.
