This history is not recorded. I also checked some information, and there is no such record. However, there were two kinds of tiles in Han dynasty, namely, pipe tile and slab tile, and stone que and Ming ware were both used together. As is common in later generations, Hanwa has no glaze, but is painted with lime. There are many round tiles with semicircles between them. There are three kinds of tile patterns: figures, animals and plants, which should be discussed under the topic of sculpture.
