Introduction to Horse Burial Stone: According to legend, during the Tang Dynasty King Li Shimin's expedition to the east, Marshal Xue Li and the enemy general Gaisu Wen fought fiercely at the foot of Qingliang Mountain. Gai Suwen lost to Xue Li and fled. Xue Li galloped up his horse and chased him to the foot of Qingliang Mountain. Seeing that Gaisu Wen was about to flee into the mountains, he hurriedly took a bow and shot an arrow. Unexpectedly, the horse lost its front hoof at this time, and Xue Li shot an arrow into the air, allowing Gaisu Wen to escape. Seeing that he had betrayed his master, the war horse felt very guilty. Taking advantage of his master's unpreparedness, the war horse crashed into a boulder in the mountain and was buried among the boulders. Later, people called this stone "Horse Burial Stone".
