The weather in Seoul, Korea
2. If accommodation and transportation are included, I think 1 0,000 RMB is enough. Of course, you can bring UnionPay cards without money. UnionPay cards can be used in many ATMs in Korea, and the exchange rate is also the middle price. Personally, I think this is the most suitable, because I have been carrying UnionPay cards in Korea for several years, and it is very convenient to use them at any time. ATMs are also available in Chinese. There may be a little handling fee, even if it is more cost-effective than changing money.
3. The socket is different. You can go to the supermarket to buy an adapter. With the adapter, you can use the same thing as the China punch. I suggest you bring a socket so that you can use it together.
4. The daily necessities belt you mentioned can be used without it. The price is not high. A cheap toothpaste costs more than 10 yuan, and a 30-roll toilet paper costs more than 60 yuan.
I hope it helps you. . I don't know. You can ask me anytime.
