Is it safe to travel to Europe?

Generally speaking, European tourism in Northern Europe and Eastern Europe is very safe, so you must be careful when you go out. There are many points for attention in European tourism. I suggest you find a special European travel club. They have many tourists in the local area, so they can customize their itinerary and tell them what to pay attention to. Electronic tour guides can navigate in Chinese locally and provide remote translation for real people all day. It's called frog trip.
