What should you pay attention to when traveling to Europe?

1. Prepare clothes according to the season. The average temperature in Europe is 0 to 5 degrees Celsius in winter and 20 to 26 degrees Celsius in summer. It's about 8 to 10 degrees cooler than during the day. Dress lightly and comfortably. European hotels usually don’t bring toothbrushes, toothpaste, slippers and other disposable items. Out of environmental awareness. Visitors should bring their own. 2. Because European pharmacies must be opened by doctors, and medical expenses are expensive, you should bring some commonly used medicines in case of emergency. 3. Spitting, smoking and littering are absolutely not allowed. Don't speak loudly in public places. 4. When flying, never put valuables, cameras, camcorders, or cameras and batteries in checked luggage. 5. Some hotels in Europe do not have air conditioning because it is not hot at night, but they have heating. You can drink the water in the bathroom directly. 6. The time difference between Europe and China is 6 hours in summer and 7 hours in winter. Smoking is not allowed in aircraft restrooms. 7. After receiving the checked baggage, be sure to remove the old note on it to prevent misunderstandings the next time you check in the baggage, causing the baggage to be transported to the wrong place.
