Introduction to the Qipan Stone: The Qipan Stone is located in Qipangou, Tupotou. It is cylindrical, like a rolled disk, 1.2 meters high and 2.2 meters in diameter. There is a circular hole with a diameter of 0.25 meters in the middle of the disk, which runs vertically through the entire stone body. According to legend, Huo Qubing, a hussar general of the Han Dynasty, set up camp here. The general's flag was planted on the rock, hence the name.
