Introduction to the food area on the east side of the square: Between the food area on the east side of the square and the Tesco supermarket, there is a 180-meter-long Crystal Street. This is an ingenious design by the designer, with unique buildings and crystals. The promenade is unique in the country, with sparkling waves, gurgling water, trickling fountains, long lights, and wooden overpasses connecting both sides of Crystal Street, adding an exotic and leisurely interest, making people feel like they are in a beautiful scenery. The banks of the Seine River fully demonstrate the beautiful picture of the harmonious unity of man and nature.
