Perhaps you should try some spelling variations:
dong hoang » hong hong
hoang fan » zhang fan, yang fan
yang mind » yang cindy, yang jin, sang minh
than bau » than bad, than you, than big
can data » can tata, dan data, fan data
mind how » aid how
how hai » how has, how ai, how hci
than a » than _

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 fan ((((than bau) OR (than a))) OR (can data)) yang mind how hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong hoang fan ((((than bau) OR (than a))) or (can data)) yang mind how hai ;~".
• Adding a wildcard symbol may retrieve word variants: dong hoang fan ((((than bau) OR (than a))) or (can data)) yang mind how hai ;*.
