Guo Chongtao
After Later Tang's conquest of Later Liang, Li Cunxu, who saw himself as the legitimate successor to Tang, exiled a number of Later Liang officials who were from Tang aristocratic families, to punish them for, he reasoned, betraying Tang. As part of these exiles, Zheng Jue was sent to Lai Prefecture to serve as its census officer. Shortly thereafter, he was slightly promoted to be the military advisor to the prefect of Cao Prefecture (曹州, in modern Heze, Shandong). Nevertheless, Zhang Quanyi, who had become an honored Later Tang official after submitting to Later Tang, was interceding for him with Li's chief of staff Guo Chongtao, trying to get him made chancellor again; instead, though, he was made an advisor to the Crown Prince — an honorary position as there was no crown prince at that time.
