I received an automated voice call informing me with this message - "This is from airport customs and we're holding your important documents. Press 2 for more information." then chinese pre-recorded was heard. i pressed "2", then man answered in Chinese so i said "hello" but he hung up immediately.

Editor's Note: Please end the call immediately when you hear the automated voice call as government agencies will not call residents through such system. Don't engage with the caller.
