Introduction to Yunshan Tun: Yunshan Tun is built on a mountain and is surrounded by walls, making it easy to defend but difficult to attack. The ancient post road passes through the village, and at its peak there were more than a thousand residents. The remaining ancient dwellings, streets, temples and theaters in the village all show its former glory. Due to its relatively complete preservation of the ancient architecture and cultural ecology of the Ming and Qing Dynasties, Yunshantun was listed as a national key cultural relic protection unit in 2001; in 2005, it was awarded the title of "China's Famous Historical and Cultural Village" by the State Administration of Cultural Heritage of the Ministry of Construction.
