A large number of ethnic myths about dragons are told throughout China. The Houhanshu, compiled in the fifth century BC by Fan Ye, reports a story belonging to the Ailaoyi people, which holds that a woman named Shayi who lived in the region around Mount Lao became pregnant with ten sons after being touched by a tree trunk floating in the water while fishing. She gave birth to the sons and the tree trunk turned into a dragon, who asked to see his sons. The woman showed them to him, but all of them ran away except for the youngest, who the dragon licked on the back and named Jiu Long, meaning Sitting Back. The sons later elected him king and the descendants of the ten sons became the Ailaoyi people, who tattooed dragons on their backs in honor of their ancestor. The Miao people of southwest China have a story that a divine dragon created the first humans by breathing on monkeys that came to play in his cave. The Han people have many stories about Short-Tailed Old Li, a black dragon who was born to a poor family in Shandong. When his mother saw him for the first time, she fainted and, when his father came home from the field and saw him, he hit him with a spade and cut off part of his tail. Li burst through the ceiling and flew away to the Black Dragon River in northeast China, where he became the god of that river. On the anniversary of his mother's death on the Chinese lunar calendar, Old Li returns home, causing it to rain. He is still worshipped as a rain god.
