Introduction to Liuchi Alley: Liuchi Alley is located in Tongcheng, Anhui Province. It starts from Xihoujie Alley in the east and reaches Baizitang in the west. It is 100 meters long and 2 meters wide, and is paved with cobblestones. The Five Thousand Years Cultural Expo Park has built an alley 26 meters long and 2 meters wide in Anqing Garden, so that visitors can feel the baptism of the harmonious wind and understand that the width of the Liuchi Alley is not just six feet wide. Rather, "wideness" lies in people's spiritual realm and spirit of harmony and courtesy.
