When the bell of the day clock rang, I was walking through Prague Square. Running away from the astronomical clock, a group of white pigeons flew past them. I picked up my feet and looked up at the thousands of people who had a history of more than 600 years. Astronomical clock, the twelve beautiful Jesus disciples appeared in order from the side of the clock, six turned to the left, six turned to the right, with a roar of the rooster, the window closed, the clock sounded It sounds. Almost touched by this moment, I finally arrived in the Czech Republic and stood under the astronomical clock. When I came to Prague, I was confronted with a continuous cloudy sky, but the clouded sky did not affect the excitement of the Old Town Square. On the ancient slate in the center of Prague Square, every day you can see that there are stray singers singing, flexible fingers jumping on the keyboard keys, and a low-pitched voice that spreads through the microphone and attracts passing Czechs. Young people and travellers sit on the ground and cheer at the end of each song, such as a small concert. Of course, you have to have a small partner to listen to, or a single girl will be killed by the couple.
