What are the decorative features of painted pottery of Majiayao, Banshan and Machang in Neolithic age in China?

Majiayao painted pottery, middle painted pottery and Machang painted pottery have more than two units arranged continuously, and the arrangement form is more dynamic. Contrast forms such as black and white, size, straightness, density and reality have been fully used in the decoration of spiral patterns and vortex patterns. In composition, we should not only pay attention to the rhythm and rhyme in horizontal arrangement, but also pay attention to the rhythm and rhyme in vertical arrangement from top to bottom. In Majiayao and painted pottery in Mid-levels, the method of setting off the theme pattern with dense and sparse ground patterns is widely used from time to time, which has become the original style of "opening the light" in China traditional decorative arts. The shape of "opening light" is mostly round and gourd-shaped, filled with various geometric patterns. The application of formal beauty is the lifeline of decorative art, and painted pottery is a successful beginning and has made amazing achievements.
