Why do most of us Shandong people have two fingernails on our little toes? And no protruding back of the head?

I know toes, because there was a flood in ancient Shandong, and many people died. The imperial court moved many people from Yunnan and other places. Some people can run on the road, so the officers and men cut off their little toes with knives and tied their hands behind their backs. They have been in Shandong for more than three years, which is why some Shandong people usually like to carry their hands behind their backs.

Hometown, where are you from? Those ancestors should have moved here. They have moved to more than one place in history, so foreigners say that the appearance of Shandong people is the most representative among China people.
