1. Cold-proof clothing. When traveling to Finland in winter, “how cold is it?” and “how thick should you wear?” are the first questions. Pay attention to the weather forecast of your destination in advance. The temperature in the northern polar circle of Finland may reach minus 40 degrees in winter, and it is windy and snowy. Thick, medium-length down jackets are a must. Warm clothing that can be prepared also includes fleece warm pants and windproof warm pants. Under the down jacket, you can choose a sweater or other clothing based on your personal feel. It is best to choose a waterproof material for your down jacket, because there is a lot of snow in the polar circle. If the outer jacket is not waterproof, it will be more troublesome after snowing. If you participate in winter outdoor activities in Finland, regular activity companies will provide outdoor warm clothing, shoes, gloves and other equipment to ensure that you will not get frostbite or catch the cold during outdoor activities.

2. Shoes. Be sure to choose waterproof and non-slip shoes, preferably boots, to ensure your ankles don’t get cold.

3. Accessories. Warm hats (preferably Lei Feng hats that can protect your ears), earmuffs, scarves, and gloves are all necessary. The gloves should preferably be waterproof.

4. Warm equipment. You can consider bringing a baby warmer for all parts of your body.

5. Cash, credit card. Finland uses euros locally, so you should exchange some cash for backup before traveling. And prepare some extra change. Euros with a face value of more than 100 yuan are considered "super large bills" in the local area, and ordinary shops will refuse to collect them. VISA and MASTER credit cards are relatively popular local credit cards, while UnionPay cards and mobile payments are rarely used locally. It is best to exchange for a chip-type credit card from the bank before departure to ensure payment security.

6. Mobile WIFI. The best way to obtain portable Internet in Finland is to rent mobile WIFI in advance at a price of 40-60 yuan/day. The signal effects vary according to different supply companies. Please read the purchase reviews carefully before renting to help you choose.

7. Mobile power supply. The weather in Finland is cold and electronic devices consume a lot of power. It is necessary to carry a mobile power supply with you. It should be noted that please confirm that the mobile power supply is produced by a regular manufacturer and has a marked capacity on the power supply. Mobile power supplies without relevant clear markings will be seized and confiscated by security before boarding the plane.

8. Conversion plug. When traveling abroad, regardless of whether the plugs are the same, bringing a converter plug will add a lot of convenience to the journey.
