The Constitution Square is similar to Tiananmen, the heart of Mexico City. If you come to Mexico, it is recommended to live near this place. First, it is convenient to travel. Second, you can stand at the commanding heights to see the scenery, but don't expect too much. The square is a vendor selling small commodities, a couple who are in love, sitting on the ground. For the pastime, if you are not lucky, you will see a temporary construction. It feels like coming to a random square. It is very interesting to sit in the square and see the crowds, such as a charming man or some interesting street performances. The square also has a flag that is 55 meters long and 31.43 meters wide and has a large and heavy area of over 1,700 square meters. The flag drop mentioned in countless Raiders must be seen. It is very shocking and interesting. On the last day of departure, I only wait until the flag is over.
