In the Tang Dynasty, the statues of Peking University and Nanda University were all shaped by clay sculpture with stone tires.

Clay sculpture, commonly known as "painted sculpture", is an ancient and common folk art in China folk tradition. That is, folk handicrafts that shape clay into various images. The production method is to mix a little cotton fiber into the clay, tamp it evenly, knead it into mud blanks with various patterns, dry it in the shade, coat it with base powder, and then color it.

It takes soil as raw material, hand-shaped, or plain or colorful, with figures and animals as the main ones. Clay sculpture is commonly known as "painted sculpture" and "clay play" among the people. Clay sculpture originated in Fengxiang County, Baoji City, and is popular in Shaanxi, Tianjin, Jiangsu, Henan and other places.

According to the national service platform of arts and crafts industry, clay sculpture is to shape all kinds of people and animals with delicate soil. In the Neolithic sites in China, early clay sculptures were unearthed many times, and then they mainly developed in the form of colored sculptures with painted surfaces.

The function of clay sculpture can be divided into two categories: religion and folk custom. The former is mainly enshrined in Buddhist temples, while the latter is mostly furnishings and children's toys.

On May 20, 2006, it was selected into the first batch of national intangible cultural heritage list.

In the Tang Dynasty, clay sculpture reached its peak. Yang Huizhi, known as the master of sculpture, is an outstanding representative of sculpture in the Tang Dynasty. After studying under Wu Daozi in Zhang Sengyou, Hui Zhi was unwilling to lag behind. He resolutely burned the brush and inkstone and devoted himself to plastics, eventually becoming a famous artist.

Only then can it be praised by the world: "Tao painting, the plastic of wisdom, can get the pen of Tao monk." With the development of clay sculpture art in Song Dynasty, not only the large-scale Buddha statues with religious themes continued to prosper, but also the small clay toys developed. Many people specialize in clay figurines and sell them as commodities.
