Shi Siming
It is not known when Shi Chaoyi was born, but it is known that he was the oldest son of his father Shi Siming (and therefore likely born after 720), and that he was not the son of Shi Siming's wife Lady Xin. The second historical reference made to him was in 757, when Shi Siming, who was a childhood friend of An Lushan and who served under An Lushan during An Lushan's service as a Tang Dynasty general and then as the emperor of his own rebel state of Yan, turned against An Lushan's son and successor An Qingxu and submitted to Emperor Suzong of Tang, along with the Fanyang (范陽, modern Beijing) region that he controlled. Shi Siming, after his submission to Tang, made Shi Chaoyi the prefect of Ji Prefecture (冀州, roughly modern Hengshui, Hebei).
