Tied horse stone carving is a unique folk stone carving art in northern China. It was originally a practical carved stone tied to mules and horses by wealthy families such as squire. It is carved from a solid and wear-resistant blue stone carving, generally 2-3 meters high and 22-30 centimeters wide, and is often planted on both sides of the gate of rural houses.
The four gods of bluestone are tied with horse stakes, and the town house can ward off evil spirits and can be decorated and placed.
