The cost of living in Gyeongbuk is truly shocking ㄷㄷㄷㄷ

‌I went on a trip to Daegu
The prices were so cheap, I was genuinely surprised
In Seoul, it's often difficult to eat a meal for even 10,000 won
But in Daegu, you can eat for 5,000 won, and there are many options for 7,000–8,000 won
Also, I recently went on a trip to Gyeongju
I thought it would be expensive since it's a famous tourist destination
But it wasn't at all; it was incredibly cheap
Even Hwangridan-gil, which is a major tourist hotspot, didn't feel that expensive
I've traveled all over the country in my own way
But the Gyeongbuk area really feels noticeably affordable
I wonder what the reason is
