In ancient tombs, there is also a kind of tomb monster, which is used to ward off evil spirits and protect the safety of the dead. This kind of pottery tomb beast appeared as early as the Warring States period. Among the tombs of the Northern Dynasties, the figurines with human heads were more popular and varied in Sui and Tang Dynasties. Many grotesque figurines were unearthed in the tombs of the Tang Dynasty, and there were also "mighty gods" full of ghosts. The latter is probably influenced by the use of the Heavenly King Warrior as the protector in Buddhist statues, and its image is very similar to that of the Heavenly King in Buddhist grottoes. For example, some tomb-protecting statues unearthed in the tombs in Xi area and Dunhuang, Gansu province, their ghost images, armor, costumes, glaring fists, etc. are all consistent with the French king. They stepped on the ghost pawn at the first step to show their strength and make the incoming ghosts daunting. This technique of setting off is also seen in the Buddhist statues of Rhyme King.
