Introduction to the ancient village: Pass through the ruins of the polder gate and the sentry gate, and guided by the dimly lit ancient rock paths and stone bridges, you will pass through the old stone buildings covered with grass on the eaves. If you open the mottled black doors of a house, you will find some long-standing stories. The long-sleeping stone mills, stone mills, stone mortars, stone jars, ancient wells and horse-tethering stones in front of and behind the house will also become the beautiful notes of the ancient folk song.
