Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, yang yang
thanh bau » than bau, than bad, thanh dam
amin hong » min hong, among hong, tin hong
vi thanh » thi thanh, van thanh
bau yong » au yong, bau von, ah yong
mind non » mind how, aid non
yang vi » yang di, yang xi, yang yi

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 vi thanh bau yong ((mind non) OR (amin hong)) hai ;~.
• Adding a wildcard symbol may retrieve word variants: dong yang vi thanh bau yong ((mind non) or (amin hong)) hai ;*.
