Prague Square is one of the most beautiful cities in Europe. The most famous square is the Old Town Square. The center of the Old Town Square is the statue of Yang & Huss. The most distinctive ancient building of the square is the self-ringing bell. The name Prague comes from German, which is called Prague locally, meaning "threshold" because the Voltava River flows through a reef here and the current is so turbulent that it seems to cross a threshold. For a cup of coffee in the roadside cafe, he sat in the corner of the square and watched the sunset set set. Once the unique astronomical clock was designed, the puppets of the twelve disciples of Jesus would come out in turn to tell the time. At the same time, the God of death would touch the copper bell underneath. The whole process ended with a cock's call.
