Introduction to the Immortal Footprints: The "Zhengfei Immortal Seal" is a rock that records the Immortal Seal. It is 12 meters long and 2 meters wide. There are 6 lines of black concave impressions the size of footprints on it. The rock belongs to the Permian Qixia limestone. Because the siliceous lenses in the rock layer are distributed in layers but are not continuous, and the lithology is different, deep footprints are formed one after another.
