Contrary to what the media say, Iran is a safe country. However, you need to be able to express yourself in emergencies in Iran. Like anywhere else in the world, as a traveler or a foreign citizen you may have problems in Iran. In this case, knowing these phrases in an emergency can be of great help and rescue you.
Fortunately, Iranian people culturally love to help each other very much and do not hesitate to help a traveler, foreign or domestic in.
This is what you feel if you ever travel to Iran. Just ask someone for an address. Even if they don’t understand your language, they try to help with gestures or immediately look for someone who is familiar with your language. It’s funny.
