Walking in the Gothic Quarter in the early morning, without the hustle and bustle of the weekdays, I was deeply impressed by the profound cultural heritage of European classical architecture. Suddenly I thought that if I came here with the group, I could only feel the crowds and noises, or the quiet scenery would not go. Occasionally there are artists performing on the corner of the street. The old town is really a place of literature and art, and even the street performers are so literary. Unlike other places, the street performances here are generally classical music players, including harp, violin, clarinet, etc. These should be the elegant art on the stage in my worldview, but it is not expensive here. As long as someone appreciates it, elegant music does not play wherever.
