Why do Han people carve the image of Hu people on the horse stone tied to their yard?

Han people's admiration for Hu people's superb horse training skills changed from wonder to admiration, and even carved a mighty and fierce image on the horse-tying stone in their own courtyard, hoping to tame livestock with its prestige and keep them safe. Some Hu people also ride auspicious beasts, which further strengthens their spirit of seeking happiness and avoiding evil and disaster. Stone monkeys of various shapes can often be seen on the tied horse stone. It is said that this is the statue of the Monkey King, the "Bi Marvin" of Tianguan. In addition to the conference semifinals and monkeys, stone lions are also common on the stones where horses are tied.
