Introduction to the old street: The old street starts from Cihang Temple and goes straight to the west gate. It is more than one kilometer long and about 4 to 5 meters wide. It was called Xizhi Street in the Ming Dynasty. Before the reform and opening up, it had always been the center of Yongning's business and trade, such as supply and marketing cooperatives, vegetable markets, handicraft workshops, and even banks, taxation, post and telecommunications units, etc., all crowded in this narrow old street.
