There is no problem for South Korea to take the subway in Seoul. Some big stations have Chinese, and then the station will have Chinese. If you buy a T-money card in advance, you don't need to buy a ticket separately, and you don't need to refund the deposit. Swipe once in the station and once out of the station.
When taking the subway, the key is not to go in the wrong direction and know which station you are going to. There are usually two stairs on the left and right, so it is not easy to tell which way to take before getting off. You can ask the conductor next to you first, or you can go down and have a look again. There is usually a sign on the subway door which direction to go.
It's best to download a subway map comparing China and South Korea on the Internet or mobile phone, which can be downloaded from Han You. There are Chinese-speaking staff in the duty-free shop in Myeongdong, so don't worry. Many shops in Myeongdong have staff who can speak Chinese, so don't worry.
Matters needing attention in Korean tourism:
1. Subway: There are far more people taking the subway than taking the bus in South Korea, because the Seoul subway extends in all directions and covers almost every place in South Korea. In China, the distance between subway stations is generally very long, but the distance between subway stations in Korea is very close, which is not much different from that of bus stations.
When you take the subway in Korea, you don't need to buy a new ticket if you miss the station, take the wrong direction, or temporarily want to go out to go to the bathroom and then go back to the subway. South Korea's subway entrances and exits have temporary exits. If anything happens, just press the button of the temporary exit and a staff member will open the door for you. You can pass when the light is on or the music stops.
2. Seats: There are special seats for the elderly, the weak and the sick in the subway. A few years ago, pregnant women's seats were set up. You are not allowed to sit in these positions. Even if the car is crowded, these seats will still be given to those in need. So we should abide by some local rules.
At the same time, the seats on the subway can be heated, which will increase the temperature of the seats in winter. It's really warm to have a warm seat on the subway after a busy night. Most bus stations in Korea provide seats for people waiting for the bus to sit and wait. These seats also have heating function, but they have not been fully popularized at present, and only a few seats can be heated.
3. Buy a ticket: South Korea's bus card is omnipotent. Except cash, most means of transportation can be settled by bus card. South Korea's bus and subway bus cards are integrated, and there is no extra charge for transferring within half an hour between them, only overtime or over-distance charges will be charged.
Therefore, when you need to transfer when you go out, you don't need to worry about the bus fare at all. In addition, high-speed buses in South Korea can also swipe their bus cards directly, but remember to swipe their cards when you get off, otherwise they will be charged according to the farthest distance of the whole journey.
4. Time: In Korea, there is no deadline for selling tickets, only you can't catch up. If the ticket gate is close to the bus location, tickets will be sold to you two minutes in advance. At this time, you only need to get the ticket and run as fast as you can, because there is no security check in South Korea by bus.
