Introduction to Shuangmending: The main street is commonly known as Shuangmending, which refers to the two stone archways "Shang Shutanhua" and "Three Generations Prime Minister" from the Wanli period of the Ming Dynasty that stand across the street. The archway is built with alternating blue and white stones, and the architectural style is a combination of hardness and softness. It has both the boldness and roughness of the north and the delicacy and elegance of the south. The square is full of carvings and decorations, with exquisite craftsmanship and lifelike quality.
