Why is Chaotian the capital of plank roads?

Because the Xia Mingyue plank road in Chaotiancheng is the one with the most dangerous geographical position, the most scientific shape and structure, the best preservation and the oldest style of plank road in China so far, it is obviously different from the Sanqingshan plank road today in terms of materials and functions. The shape of Yuemingxia Pavilion is supported by beams. Stones cut through the wood at the cliff, and the vertical wood is inserted at the bottom of the river or supported on the beam. Sitting on the boat, you can clearly see that the caves on the cliff are arranged in three layers, the upper row is for the erection of awnings, the middle row is for the pedestrian plank road, and the lower row is for reinforcement and support. Therefore, Xia Mingyue ancient plank road is a real ancient plank road.
