Introduction to Zhishan Pavilion: There were originally 7 post pavilions and 7 temples built on the post road. Now there is only one ancient post pavilion with three beams and wooden structure that has been preserved, named "Zhishan Pavilion", located in Ding Maxian Changchun Ridge is an important stopover place on the ancient Ma'ao Post Road, where pedestrians and horses on the post road can rest. It has also become an important circumstantial evidence for today's research on the culture of the ancient Ma'ao Post Road. The Zhishan Pavilion was rebuilt in the 19th year of Guangxu (1893). In 2001, the Ma'ao Town Government also renovated this pavilion. There is a stone wall several hundred meters long on each side of the pavilion. According to records, it was built during the fight against Japanese pirates. The stone wall is 2 meters high, with huge stone foundations and a trench dug on one side of the wall. Nowadays, due to the passage of time, the road surface has basically been destroyed, and some of it has been submerged in weeds. Only the Zhuyuan section and Yancang section of Wuyi Village are relatively well preserved.
