Gai Tian Shuo detailed data daquan

Gaitian theory is the cosmology of ancient Han nationality. This theory may have originated from the late Yin Dynasty and the early Zhou Dynasty, and there are several different views in its development. The early theory of covering the sky thought that the sky was round and the place was like a chess game. The dome-shaped sky covers the square flat earth, but it can't match the square edge of the earth. Then it was suggested that the sky does not touch the earth, but hangs high above the earth like a big umbrella, supported by eight pillars around the earth, and the shape of the sky and the earth is like a pavilion with a dome at the top. * * * The workers' anger can't touch the myth of Zhoushan and Nu Wa, which is based on this view.

There is also a later theory that the sky is spherical and the earth is spherical, and the distance between them is 80 thousand miles. The North Pole is in the center of the sky, and the sun, moon and stars revolve around it. Gaitian theory usually interprets the appearance of the sun, the moon and the stars as the change of their running distance. If they are far away, they can't be seen, but if they are close, they can be seen shining.
