1.In the lane

We strongly advise travelers not to carry more money than they need while walking around the streets, particularly when you are alone, to avoid being robbed or being victims of pickpockets. Wear as little jewelry as possible, since would-be thieves draw unwanted attention from even fake jewels. In fact, robbers and drive-by snatchers do not have time to determine whether or not jewelry is of high value; they simply take whatever opportunity through the carelessness of a moment comes their way.

Make sure your bag, if any, is not on display or easy to catch when taking a ride by xe om (motorbike taxi). Although reasonably uncommon, bag snatches are possibly the most probable crime that a visitor would experience, and if your precious camera or laptops are clearly noticeable, the danger is tremendously increased.

2.Cultural considerations

It is considered impolite to wear large quantities of jewellery because it appears to flaunt riches in public.

Do not wear Temples and Pagodas singles, shorts, dresses or skirts, or tops with low-necklines and bare shoulders. It is considered highly disrespectful and disrespectful to do this. When you see any local ladies wearing them, don’t be surprised. In several official and unofficial debates in both online and print / media, such dress is currently being criticized. For locals, you should not build any ways to blame western culture.

When in someone’s home, never sleep or sit with the soles of your feet pointing toward the family altar.

In public or when negotiating for a deal, never lose your temper. For both sides, this is considered a significant loss of face. Always keep a calm and positive attitude and the same will be reciprocated for you.

There are frowned upon physical displays of affection between lovers in public. That’s why you will usually see couples holding hands while you can very rarely see a couple in the public area kissing each other. You can possibly catch several couples hugging or even kissing in front of a camera to pose their selves. In reality, they are part of the new generation of Vietnamese who are open-minded and inspired by the film and entertainment field.

  3.Minorities of national origin

When trekking through ethnic minority villages, avoid giving empty water bottles, sweets and candies or pens to the local people. You do not guarantee that the empty bottles are properly disposed of, and that people do not have access to dental hygiene. Ask your guide to introduce you to the local teacher and donate them to the whole group if you want to offer pens.

Never take video cameras to the villages of ethnic minorities. The local people consider them to be too invasive.

4. Governmental Considerations

If your material stays away from controversial news about the government, blogging is appropriate. Sharing your private experiences and evaluating accommodation or restaurants, but nothing else, is OK. Discussing something like government corruption or even the Vietnam War will lead to a hostile reaction from the authorities. This crucial argument is also undoubtedly highlighted. When traveling in Vietnam, it is easier to forget the word “Freedom of expression.”

Do not attempt to take photos of military installations or something that is connected to the military. This can be seen as a national security infringement.

It is profoundly unethical to do something that portrays pornography. Prostitution appears to be illegal as well. If you love bars and nightclubs, you may be interested in Ho Chi Minh City and Hanoi. But please bear in mind that it is usually not allowed to share a hotel room with a Vietnamese of the opposite sex.

In Vietnam, trafficking in or possession of drugs is illegal and a capital offense. As in other nations, in terms of prevention or even elimination, substance addiction costs a lot, but it seems like it can never be fully eradicated. Therefore, when you are traveling in Vietnam, do not ever take drugs with you.
