Introduction to Tianshu Cliff: The cliff is 286 meters high, and the height of the inscription is 150 meters. Each of the three characters "Tian Shu Cliff" is 5 × 5 meters in size, with a spacing of about 4 meters. It is the highest cliff stone carving in the country so far. The cliff body is mainly composed of shale and slate. The blue and white stone cliffs are arranged on both sides, very much like a giant open book. The rock surface has clear lines, as if there are words outlining it, hence the name Tianshu Cliff.
