Every piece of bluestone on the ancient city wall bears the dribs and drabs of the historical changes of Chaling, and every piece of blue brick has witnessed the ebb and flow of the Yongjiang River for 800 years. We expect the ancient city wall of Chaling to be presented to the world with a brand-new look.
