Perhaps you should try some spelling variations:
dong hoang » hong hong
hoang yang » huang yang, wang yang, yang yang
yang than » yang dean, yang fan
than you » can you
you yang » yu yang, you liang, zhou yang
mind how » aid how
min hong » amin hong, tin hong, min hyoung

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 yang than you yang ((mind how) OR (min hong)) hai ;~.
• Adding a wildcard symbol may retrieve word variants: dong hoang yang than you yang ((mind how) or (min hong)) hai ;*.
