The chronicles of the reigns of Emperor Shang's father Emperor Zhongzong and uncle Emperor Ruizong, which included his own brief reign, in the Old Book of Tang, indicated that he was 15 at the time of his brief reign in 710, making him born in 695, but, in his own biography, gave his age as 16 at the time of death in 714, making him born in 698. It is not known which account is correct. Compare Old Book of Tang, vols. 7 and 86.
