The wind in the northern part of the Great Wall has always had a sharp edge. It swept the yellow sand across the Gobi Desert, spread over the ruins of the beacon tower, and also blew through the heavy general's order. This is a work soaked in wind and sand, with the majestic frontier fortress scenery as the background, and the sonorous military spirit as the flesh and blood. It tells the magnificent legend of a general and his soldiers who defended the territory and wrapped their bodies in horse leather in the age of war.
