Introduction to the interior of Site No. 2: This is mainly the site of a Tang Sancai kiln, which was excavated by the Shaanxi Provincial Institute of Archaeology in 1985. The main relics include a group of Tang Dynasty tricolor workshops (composed of 7-hole cave dwellings), 3 baking kilns, and 1 small trial kiln. In the workshop, there are also remains such as the shaft pit for installing the wooden runner, forming molds, fire pits, pottery basins, clay materials, and utensil blanks. In addition, there are Song Dynasty kilns, Jin Dynasty porcelain workshops, mud washing facilities, etc. The site truly reproduces the sequence, division of labor and craftsmanship of Tang Sancai firing.
