2. Speaking of economy, eating in the school canteen is the cheapest, and each meal in the canteen is about 10 yuan, which is similar to the price of eating a fast food in China, hehe.
The transportation in Korea is very convenient. To go to Seoul, you can take ktx (equivalent to domestic bullet train 1 hour) or bus (2 hours). If you go to Cheongju, you can get there in 40 minutes by bus.
As for your slum, this is a bit exaggerated. Hehe, South Korea looks a little prosperous except Seoul, and any other city is similar.
It is very convenient near Pinus tabulaeformis University. It's cost-effective to take a taxi to two large supermarkets 10 yuan, and it's convenient to buy clothes and things like that. There is a direct bus at the school gate (about 15 minutes).
6. Finally, I wish you success in your studies and a happy life in Korea ~ ~ ~
