Tang of Shang
According to Chinese mythology, the Zhou lineage began when Jiang Yuan, a consort of the legendary Emperor Ku, miraculously conceived a child, Qi "the Abandoned One", after stepping into the divine footprint of Shangdi. Qi was a culture hero credited with surviving three abandonments by his mother and with greatly improving Xia agriculture, to the point where he was granted lordship over Tai and the surname Ji by his own Xia king and a later posthumous name, Houji "Lord of Millet", by the Tang of Shang. He even received sacrifice as a harvest god. The term "Hòujì" was probably a hereditary title attached to a lineage.
