Why don't Korean canteens serve meat?

Korean meat is very expensive. Many people yearn for Korea, mostly influenced by Korean dramas. There are also some "foodies" who watch a lot of Korean anchors, munch on delicious food and think Korean food is great. But Korean meat is very expensive, and a catty of beef costs nearly 40,000 won, which is 200 yuan RMB. Therefore, there is almost no meat in Korean canteens, and many students have reported that it is really a pity to study in Korea, and they have been "cheated" by Korean dramas.
