Bo Yang
The commentator to the "Zizhi Tongjian", Hu Sanxing, toward the end of Song Dynasty, was in turn very complimentary of Li Bi, believing that his dabbling in Taoism was a way to avoid getting in danger, while making exceptional contributions during the reigns of three emperors. His view was shared by the modern historian Bo Yang, who even ranked Li Bi to be the most talented Chinese chancellor since Wang Meng. Bo was particularly complimentary of Li Bi's suggestions that led to the gradual alleviation of Tufan attacks against Tang.
