Do the old kilns in Song Dynasty refer to the five famous kilns?

The theory of the five famous kilns in the Song Dynasty was first found in Xuande Ding, the royal collection catalogue of the Ming Dynasty: "The wares of Neiku Chai, Ru, Guan, Ge, Jun and Ming kilns are elegant in style and the drawings are presented." In the Qing Dynasty, Xu Zhiheng's Talk about Porcelain in a Drinking Room said: "Porcelain making in China can be divided into three periods: Song Dynasty, Ming Dynasty and Qing Dynasty. There are five most famous songs in Song Dynasty, namely Chai, Ru, Guan, Ge and Ding. It is also very valuable to have a kiln. " As there is no kiln site and no physical objects in Chai Kiln, Jun Kiln is usually included, and it is called the five famous kilns in Song Dynasty together with Ru Kiln, Guan Kiln, Ge Kiln and Ding Kiln.
