Textual research on the legend of secluded nest

Legend has it that Youchao was born in Cangwu at the southern foot of Jiuyi Mountain. Inspired by birds nesting in trees, "nesting" was first invented. You Chao's family instructed people to build houses on tall tree trunks with branches and vines. The walls and roofs of houses are tightly covered with branches, which can not only protect them from wind and rain, but also prevent animals from attacking them. People no longer live a life of fear.

In the past, some scholars believed that the birthplace of the nest was Cangwu (now south of Jiuyi Mountain in Hunan) and Shilou Mountain (now northeast of Lvliang, Shanxi). Some people think that Chao was born in Shandong, or in Shanxi and Inner Mongolia. The map of Dunjia Mountain, a Wei book in the Han Dynasty, said: "Shilou Mountain was there, and the Chao family once ruled this Shan Zhinan."
