Perhaps you should try some spelling variations:
dong hoang » hong hong
yang amin » yang jin, yang lin, yang mind
amin dang » yimin dang, amin hong
hoang ka » hoang vu, hoang sy, hoang _
than bad » than bau, than a, than big
can data » can tata, dan data, fan data
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: dong hoang ka ((than bad) OR (can data)) yang amin dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: dong hoang ka ((than bad) or (can data)) yang amin dang hai ;*.
