The Tang Dynasty opened a new type of tomb burial form. In the past, huge tomb pits were excavated downwards, and after burial, the top of the mound was covered. From the Tang Dynasty, a mountain was selected to dig a hole in the mountainside to build a tomb, and then block the tomb road. The main tomb of Qianling Mountain is Liangshan, and there are Rushan arches on both sides to guard Liangshan.
