If you are coming to Berlin for the first time, you can have a day in Berlin. The route I want to introduce below will definitely be your best choice. It is recommended that you depart from the Alexanderplatz in the heart of the Old Town. The most striking building on the square is the towering TV tower, the tallest building in Berlin. Standing on the tower, you can see the magnificent view of Berlin. From Alexanderplatz to the south, Berlin's Berliner Rathaus and the Marne's Square. There is a big fountain in front of the town hall, which is a favorite place for children to play in the summer. There are statues of Marx and Engels that are familiar to many Chinese people on the Marne square. There are many screen posts in the square that record history. If you have time, you will find a page of Chinese history there.
