Introduction to Wanjia Rock Cliff: Wanjia Rock Cliff is located on the right side of Bailong Mountain in Heba Township, west of Qiancheng City. There is a rock frame between the steep cliffs, about 1 km long and 1-8 meters wide. It can accommodate more than 500 people. It rises from the bank of the Xiaojiang River. The rock walls are stacked with black and white vertical lines. Starting from the Zhu calligraphy "Simen Pass", more than 40 calligraphy inscriptions have been discovered on the rock walls, divided into "Daka", "Zhongka", "Niu Ka", "Shijia Ka", etc. The earliest one is titled "The people who gathered into the rock turned into blood, and the stone wall was damaged and all the barbarians were destroyed", which was built in December of the second year of Zhishun in the Yuan Dynasty.
