Liangzhu Culture in the Neolithic Age

Jade cong is originally made of sapphire, but there are large areas of green spots after being cooked, which are brown. Cong is divided into eleven sections. Each section is carved to simplify the human face pattern. The crown, cap and mouth are not decorated with yin lines. The human eye has two ways: pipe drilling and carving. There are wire cutting marks left on the body that have not been polished off. The holes are opposite to each other, and there are step marks left by dislocation during drilling. The edges of the two ports of the jade cong are incomplete, which should be made from raw materials
There are two carved symbols on the outer wall of the upper nozzle of the jade cong, which are respectively carved on the corresponding two sides. One is clear, and the other is ambiguous. These two symbols are not found in archaeology and other handed down articles
