Never Think You Can Take Photos Of Anything

Be careful, there are places that ban photographs like the Ho Chi Minh Mausoleum, and military structures, or even personnel. You could spend some horrible time in a Vietnamese cell. Always ask politely if it is okay to photograph. And if you notice any military personnel around, best avoid the area. Politely ask locals permission to take their pictures, don’t just photograph them without asking. It is considered rude. Also taking photos of locals gives them the opportunity to charge you for it. Although not all Vietnamese will.
