Oslo, Norway's capital and largest city, is the political, economic, cultural, transportation center and main port of Norway, and is the seat of the Norwegian royal family and government. The cities of the Nordic countries think about how boring they are. They were originally going to stay for three days, a daze for one day, a blind day, and then retreat for one day. The city is not big. It is just suitable as a supply station and a maintenance station for two weeks of travel. I didn't expect that I stayed for seven days and went through the journey of "low expectations - boredom - surprise - buy, buy - kind".
