The table of the chancellors' family trees in the New Book of Tang gave a different name for Hun Jian's great-great-grandfather—Hun Jionggui (渾迥貴)—but Jionggui could have been a sinicized name for Hun Atanzhi. The New Book of Tang, further, indicated that the Hun family traced their beginnings to the Xiongnu Prince of Hunye. See New Book of Tang, vol. 75."漢川草廬-二十四史-新唐書-卷七十五‧表第十五".

According to Hun's biographies in the Old Book of Tang and the New Book of Tang, he was made the deputy military governor of Zhenwu, not military governor, with the title of Fudashi (副大使), but according to the Zizhi Tongjian, which apparently followed the chronicle of Emperor Dezong's reign in the Old Book of Tang, he was made military governor. As the Fudashi title would indicate that he was acting as governor but titularly serving as a deputy to an imperial prince—one of Emperor Dezong's brothers or sons—but none of Emperor Dezong's brothers or sons carried the title of military governor of Zhenwu, it would appear that Hun was made military governor.

Both Hun's biographies in the Old Book of Tang and the New Book of Tang indicated that Hun Shizhi died in battle against the Tufan, but the Zizhi Tongjian gave a different account—that he was executed by Pugu after considering, but did not actually carrying out, a resistance against Pugu when Pugu, after Pugu Yang's death, took his army back to Lingwu (Shuofang Circuit's capital). Compare Old Book of Tang, vol. 134 and New Book of Tang, vol. 155, with Zizhi Tongjian, vol. 223.
