Washington, as the capital and political center, has little of the impetuousness and bustle of the New York metropolis, and more of a cultural and historical accumulation. The three separate institutions of the United States - Congress, the White House, and the Supreme Court - are here. At 8 o'clock in the morning, the bus goes straight to the downtown Capitol Square. The 3 km long, open garden park is the site of national celebrations and ceremonies in the United States, and almost all of Washington's major attractions are covered. First visit the Capitol at the eastern end, this ancient Roman-style building is known to have become an image symbol of American democracy, and it is also one of my life's wishes to go in and see. From the stone steps of the fountain in front of the building into the elegantly decorated ground floor hall, under the guidance of enthusiastic staff to queue up for tickets (free), and then grouped by the interpreter to lead into the inside. First enter the Capitol cinema, watch a movie about ten minutes to introduce American democracy, the opening line is that such a vast land, different peoples, different faiths, different classes, different voices, can make all these differences retain each other, And to unite to form a strong country, that is the wonderful greatness of American democracy. Yeah! Since the day of the existence of a state, all people have lived under totalitarian rule, and their beliefs and interests are not compatible, and it is difficult to live in a country without union and retention of their respective beliefs and interests. America, as a strong country through democracy, can naturally proudly promote its superior political system to other struggling backward countries. After watching the movie, it ascends to the third-floor rotunda, with historical murals and statues of prominent state legislators. The narrator gushed about his history. The parliamentarians' defense venue was not open to ordinary tourists, and they could not bet on the eloquents.
