We took the subway from Milan Cathedral to Sfordsko Castle two stops away. This is an ancient castle which has a history of more than 700 years. It still has momentum after being repaired. In the gate tower, a man dressed up as an ancient Egyptian costume is exhibiting body art motionlessly. Such scenes are often seen all over Europe, which is quite interesting. There are also many exhibitions in the castle. Because of the time, we went through the castle directly, and felt the magnificence and charm of the castle's appearance with our visual field. Behind the castle is a beautiful park where many citizens bask in the sun on the grass. We also crossed the Mermaid Bridge and took a rest on the bench under the shade of the tree. Behind the vast green space is a triumphal arch of Chinese white jade. It used to be thought that the triumphal arch was only a famous scenic spot. After traveling to Europe, it was felt that the triumphal arch could be seen everywhere, but the history they witnessed was different.
