The introduction of bronze porcelain is urgent

Porcelain: evolved from pottery in primitive society. The Tang Dynasty was blue in the south and white in the north. In the Song Dynasty, there were five kilns: Ru, Ge, Guan, Jun and Ding. In the Yuan Dynasty, blue-and-white porcelain bronzes were produced: copper-tin alloys. Most of the Shang and Zhou artifacts were made of bronze, and even blue bronze inscriptions were written on them: characters were created in Cangjie in the legendary era, Oracle Bone Inscriptions on the tortoise shell of cattle bones, and seal characters in the Qin Dynasty. Painting: Rock paintings in primitive society, with simple and monotonous lines. Tomb murals in Qin, Han, Three Kingdoms, Jin, Southern and Northern Dynasties outline the social scene at that time with simple lines. Figure paintings and landscape paintings in the Jin, Southern and Northern Dynasties, and ladies in the Tang Dynasty painted jade. There is a Confucian idea that "a gentleman is precious to jade". Jade was given by the royal family as a reward in the early days, and it became a collection from the royal family to the people's homes in the Ming and Qing Dynasties.
