Liang Zhuyu introduced

Jade before the Han Dynasty was called Gao Gu Yu. With the prosperity of archaeology, after a large number of prehistoric cultures were excavated, Gaogu was divided into cultural periods and the third generation. Cultural periods are divided according to regions. Generally speaking, there are three famous cultural areas: Nanliangzhu and Beihongshan. Together with Qijia culture in the west, there are three famous cultural areas. Liangzhu culture is centered on Yuhang and Jiaxing in Zhejiang, including most of the vast areas around Taihu Lake Basin in southern Jiangsu and northern Zhejiang. Liangzhu jade is famous for its exquisite ornamentation. Jade talents are mostly local jade, one is transparent lake green tremolite, and the other is serpentine with different colors after soaking. The craft of Liangzhu culture is extremely exquisite, and there are obvious differences between early jade and late jade. But generally speaking, jade is mainly for ancestor worship, and there are fewer birds and animals. There are many tube bead ornaments, ritual vessels, jade cong, jade bi and jade Huang.
