Shang dynasty
Founding myth

The founding myth of the Shang dynasty is described by Sima Qian in the Annals of the Yin. In the text, a woman named Jiandi, who was the second wife of Emperor Ku, swallowed an egg dropped by a black bird (玄鳥) and subsequently gave birth miraculously to Xie. Xie is said to have helped Yu the Great to control the Great Flood and for his service to have been granted a place called Shang as a fief. The period before the Shang dynasty was established is known as the " Predynastic Shang " (or "Proto-Shang").
