Shanhaiguan barrier
Shanhaiguan Pass was built in the 14th year of Hongwu in Ming Dynasty (138 1). It is the center of the Shanhaiguan Great Wall, with an irregular trapezoid, and the northwest and southwest corners are curved, with no corner platform.
The circumference of Guancheng wall is 4727 meters, the height of Guancheng wall is 14 meters and the thickness is 7 meters. The East Wall is the main line of the Great Wall, which closes the east, west, north and south gates. The East Gate is the East Gate of Town, which is the first gate in the world, the West Gate is the Yingen Gate, the South Gate is the Wangyangmen, and the North Gate is the Weiyuan Gate. There are towers on all four gates.
Shanhaiguan is the barrier between Northeast China and Guanli. In addition to military use, it is also the gateway to those ghosts and gods. At that time, there were tens of thousands of soldiers guarding Shanhaiguan. In order to resist the Qing soldiers, their spirits guarded Shanhaiguan, which naturally frightened the horse fairies.
