The Song Dynasty (960- 1 126 in the Northern Song Dynasty and1/27-1280 in the Southern Song Dynasty) was a moderns in the development history of China ceramic industry. Due to the rich geographical conditions and the development of foreign trade, Jiangnan has become a prosperous and densely populated city. Lin 'an (now Hangzhou) was the political, cultural and economic center at that time, and it was also the largest consumer city. There are also Mingzhou (now Ningbo), Yuezhou (now Shaoxing), Wenzhou, Wuzhou (now Jinhua), Chuzhou (now Lishui) and other places. These towns have a long history and developed porcelain industry. They are not only porcelain production centers, but also porcelain consumption markets and distribution centers. Yue porcelain, Wuzhou kiln porcelain and Longquan celadon have long enjoyed a good reputation, each with its own genre. The difficulty of Jingkang marked the demise of the Northern Song Dynasty and the Five Dynasties. The original kiln was destroyed 2. Song Gaozong Zhao Gou fled to the southeast, with its capital in Lin 'an, and established the Southern Song Dynasty court. Xiunei Temple official kiln is located in Phoenix Mountain, Hangzhou, and the new official kiln is built near the Baguatian altar in Wuguishan, a suburb. The inner kiln and the new official kiln concentrated skilled craftsmen from the north and the south, and produced celadon needed by the imperial court and dignitaries. This is a continuation of the Bianjing official kiln in the Northern Song Dynasty, which was called the Southern Song official kiln in history. According to the book Tan Zhai Bi Heng written by Southern Song Dynasty, Zheng Hejian (Northern Song Dynasty111-1117) was built in his own kiln site. This document is the earliest written record about the history of official kilns in the Southern Song Dynasty, which was used as textual research by later generations. According to documents, the official kiln was fired in the Northern Song Dynasty. The official kiln in the Southern Song Dynasty inherited the technology and manufacturing method of the official kiln in the Northern Song Dynasty. The literature divides the Southern Song Dynasty official kiln into two parts: the inner kiln and the suburban altar. The former is called inner kiln, and the latter is a new kiln, and it is clearly pointed out that the new kiln is bigger than the old kiln. According to a site of Wugui Mountain Kiln excavated by Zhejiang Cultural Management Association 1956, the existence of Jiaotan Imperial Kiln has been confirmed. However, the official kiln site of Xiunei Temple mentioned in the literature has not been found so far, and some archaeologists have proposed it, or it is only a kiln site with Jiaotan, which is also confirmed by special research and archaeological discoveries.
