What size suitcase should I prepare for a trip to Europe?

There is a great temperature difference in European countries, such as Italy, where there is plenty of sunshine; The Swiss Alps are hot in the south and cold in the north. The climate in France is more changeable and windy. When the sun is shining, people will catch cold when there are dark clouds, so you have to prepare clothes for spring, summer and autumn, and bring some clothes hangers and laundry detergent (which can reduce a lot of burden). If it is too cumbersome, take two boxes (not too big, 60*40 is enough) and two bags, as big as possible. Put your bag in the box when you go, and you will definitely buy more things when you come back.

Water in Europe is alkaline (the kind that can lead to stones if you drink too much), so you may not be used to it. I suggest you bring a mini electric kettle and a plastic teacup. If you eat Chinese food all the way, you can add boiling water or tea everywhere. You can give it away or throw it away before you go home.

You must bring the adapter. I believe that there will be no shortage of mobile phones, cameras and notebooks. It is much more expensive to sell in Europe than in China.

I brought all the toiletries. Some hotels have nothing, but France is ok, with shampoo and shower gel.

It is suggested that men bring some old T-shirts, underwear, socks and the like, and throw them away when they are used in some places where they only stay for one night. They stay there for a few nights, and they can choose to wash clothes.

Try to choose duty-free shops when shopping, or focus on paying less tax refund forms, because French tax refund needs to be at Paris airport, and each tax refund form is charged a handling fee of 3 euros. It is recommended to buy cosmetics after getting off the plane at Beijing airport, which is cheaper than in Europe. It is the domestic price to take out your luggage and buy cosmetics!

You'd better prepare some euros (50 denominations is enough) and a credit card. If there are too many euros, it is easy to be stolen. Credit card is a backup, and it is best to have a UnionPay logo at the shopping place! Never handle American Express traveler's checks, which are troublesome and expensive to use. Change some coins immediately after going abroad for going to the toilet or tipping.
