During the Zheng Xuan period, were there a lot of porcelain in the official kilns built by Kaifeng government?

During the period of Zheng Xuan, there were not many official kiln porcelains made by Kaifeng government.

First of all, the official kiln porcelain was very precious at that time, and only members of the royal family could own it. Moreover, the survival time of the official kiln in the Northern Song Dynasty was very short, only ten years. During this period, most of the kiln factories in the north were small in scale, and the space was much smaller than that of the dragon kiln and ridge kiln in the south, which may be one of the reasons for the scarcity of official kilns in the Northern Song Dynasty.

Some experts said that even if all the world's collections are added up, the finished products of official kiln porcelain in the Northern Song Dynasty are only three figures, and the quantity is very rare. Therefore, during the period of Zheng Xuan, the number of official kiln porcelain supervised by Kaifeng government may be very limited.
