Introduction to the seal of the mountain: Located on the stone wall of Mount Palate near the lake on the east side of Longkou, Junshan, it is also known as the Qinhuang seal. It is a Sanskrit mosaic rock carving from the Tang Dynasty in Junshan. There are two existing seals, one is 1.2 meters long and 0.8 meters wide, with incised inscriptions, obvious handwriting, and ancient brushwork. Some people interpret it as "Yongfeng", some think it is "Fengshan", and some people think it is from the Yuan Dynasty. There are different opinions on the text of "Ba Si Ba", and the content is unknown. In addition, on the rock wall more than 10 meters to the left of the seal, there is a seven-character travel poem signed by Chen Sanchen in official script.
