Introduction to Mumatan: Located in the southeast of Shimen Scenic Area, the terrain is open, surrounded by mountains and rivers, with fertile soil and lush grass. It was the place where Ying Feizi, the ancestor of the Qin people, herded horses. In the past 10 years or so, the Qin and Han tombs unearthed in Mumatan include Qin slips from the Warring States Period, wooden maps, papers and other precious cultural relics. Among them, the wooden map is the earliest practical map in the world and is very precious.
