Shi Siming
On 10 April 759, An Qingxu was killed by General Shi Siming, An Lushan's loyal follower and childhood friend. Soon after, Shi recaptured Luoyang. However, on 18 April 761, Shi Siming was killed by "his" son, Shi Chaoyi, who promptly proclaimed himself emperor, even though he failed to get widespread support from the other Yan generals.
