The Feng Shui Use of Jade Cong

Jade Cong is a kind of cylindrical jade with an inner circle and an outer side. It is a ritual vessel used by ancient people to sacrifice gods, and it has been about 51 years since. In ancient China, there was a ritual system of offering jade jade to heaven and jade cong to the earth. Yu Cong and Yu Bi, Yu Gui, Yu Zhang, Yu Huang and Yu Hu are called six vessels. As one of the important ritual vessels in ancient China, Zhou Li used Cang Bi as a gift to heaven and Huang Cong as a gift to the earth. Jade Cong became a ritual vessel for the ruling class to sacrifice the vast earth, and it was also a tool for wizards to communicate with God. That is to say, in ceremonial activities, cong is used to sacrifice to the earth god. Most scholars believe that cong is a kind of instrument to communicate with heaven and earth, with the upper big circle symbolizing heaven, the lower small circle symbolizing the foreign land. The shape of the jade cong is the outside of the inner circle (hole), which seems to confirm the truth that the round wall is like the sky and the square is like the ground.
