What to wear to Paris in late May?
You can bring an umbrella or a light raincoat, and it is best to bring personal toiletries, because small and medium-sized hotels in Europe do not provide toiletries, and only big hotels and hotels with more than four stars have these things. The power plugs in Europe are round holes, which are different from those in China. And the hotel has no adapter, so buy one.
How is your language? If it is not good, you can bring a mobile phone with quick translation or simple translation function, and you can have simple communication when necessary.
A camera is essential!
Prepare some medicines and first-aid medical supplies according to your physical health, in case of emergency, just a little, not a few years!
Since it is a tour, it is most comfortable to wear jeans and sneakers. Oh, you have to prepare a formal suit, because there are many high-end coffee shops and restaurants in Europe, and you are not allowed to enter casinos without formal clothes.
You'd better pack your passport and money separately. If you lose your passport abroad, you will be in big trouble.
Tap water in European countries can meet the drinking standard, so hotels do not provide boiled water or cookers, and they have no habit of drinking boiled water. This is ready.
The most important thing is to prepare more money, and don't be blind then. If you work in Europe and the wages you earn are consumed locally, you won't feel how expensive things are, and sometimes you will feel very cheap. But in China, if you are a migrant worker and can't earn much money a month, going to Europe will make you feel that things are old and expensive, and you must be short of money.
