Perhaps you should try some spelling variations:
dong yang » dong hoang, wang yang, yang yang
kong hong » hong hong, kong hang, kong heng
yang fan » zhang fan, yang dean, yang yang
fan than » van thanh
than bau » than bad, than a, than you
bau yong » au yong, bau von, ah yong
mind non » mind how, aid non

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