Introduction to the exterior of Site No. 1: The site was scientifically excavated in 1984 by the Shaanxi Provincial Institute of Archeology. It mainly includes a group of porcelain-making workshops in the Song Dynasty composed of two cave dwellings. There are stone pestles for crushing raw materials, axle pits for installing turntables, mud training pools, fire kangs, glaze jars, glazes and other remains. There are also a billet drying yard, a stockpile yard, and multiple stacked kilns from the Tang and Song Dynasties, which systematically reflect the technological processes and technical equipment of Yao porcelain production in the Song Dynasty.
