trying to classify the unknown throws of Shuai Jiao with Judo terminology

As we are all built the same way and there is a universal design of our bodies, the same techniques will be found in a lot of styles, I don’t believe that there is an ancient common combat style that has spread from country to country throughout history. It is more likely that it’s due to our similarity of how our body works, many styles have common techniques but they are more different than what they have in common.
