Perhaps you should try some spelling variations:
than death » than data
dong yang » dong hoang, wang yang, yang yang
yang mind » yang cindy, yang jin, tang min
sang minh » kang minah, anh minh, song min
than bau » than bad, than a, than you
yang ka » yang fan, yang yao
how aid » how asia

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