Stayed in Oslo for 4 days and went to the palace three times. The palace has horseback guards, guards, and changing guards as grand and formal as other royal guards. The back garden is quite large, but not the royal territory, but the park of the Norwegian people, of course, our tourists can also freely enter and exit. Many of the children on the park grass are the father, and the woman is holding a book under the tree to hold the sun, and there is a bicycle on the side. Oslo in summer is suitable for temperatures, 20 degrees during the day and 10 degrees at night, very comfortable.
