What should I pay attention to when traveling to Paris, France?

All mentioned are based on the premise of not joining a group. If you join a group, the tour guide will usually explain it in detail. The first thing that must be said is security. When staying in Paris or similar big cities, it is common to be stopped by black people asking for money and cigarettes. Therefore, it is recommended not to bring too much cash, and prepare some small banknotes such as one euro and ten euros. If you are stopped asking for money, give it quickly; There is also the need to beware of thieves in downtown areas, especially when visiting scenic spots; Finally, if you are a woman, you'd better not go out alone at night, especially if you live in 13, 18, 19 or 20. Also, if you see some behaviors of some blacks or Middle Easterners, don't stare or discuss with others, just walk away; Although the overall public security in big cities is a bit chaotic and generally safe, it is always good to take more precautions abroad. In addition, some places worth visiting in France are small towns. The air, environment and atmosphere of the town will make people feel that they are in an isolated fairyland. I recommend a coastal town-La Touquet (France), which is worth visiting. There are still some small things to pay attention to. If you want to smoke, you can't smoke in all rooms, including electronic cigarettes. The smoke detector in the hotel room is very hidden. Don't think that there is no such thing as smoking outdoors honestly. The subway traffic in Paris is very convenient, but the lines are very complicated. If you accidentally miss your stop, you will feel relaxed. Just sit back in the opposite direction, but it will be easy to get confused. So, if you don't know French, you must be very careful when you take the subway, and then you must remember the name of the subway station when you leave. Think so much for the time being. If you have anything else, just ask.
