"Back-up" capital, people will turn it trash just like Seoul and prices will be higher as more and more people move there.
Busan better than Daegu? At what? It nice coast city indeed, but it's being flooded by foreigners just like Seoul and price are high I assume. It's one of best cities in here, but overrated. One of few good things that are in Busan is the area that foreigners avoid because there Koreans actually remind that they aren't natives.
