What are the characteristics of fish patterns of painted pottery in Banpo of Yangshao culture in China?

The description of fish shows the ability of Banpo ancestors to change sketches. On the one hand, they are very familiar with the shape of fish, on the other hand, they are not bound by objective modeling. For example, fish scales are not simply represented by crossed net lines, but are decorated with black and white contrasting color blocks. There are many forms of fish, including haploid, diploid and even trisomy.
