In 830, Pei, as he was old by this point, offered to resign his chancellorship. Emperor Wenzong, in response, made him "Situ" (司徒, also one of the Three Excellencies) and gave him the unusual chancellor title of "Pingzhang Junguo Zhongshi" (), ordering him to report for duties only once every three or five days. Soon thereafter, however, as Li Zongmin resented Pei for having recommended Li Deyu over him, he had Pei sent out of the capital to serve as the military governor of Shannan East Circuit, carrying the honorary chancellor title of "Shizhong" (). Once he reported to Shannan East Circuit, at his request, a large grazing range at Shannan East that was used to breed military horses, which was not yielding much results, was abolished, and the fields were returned to the farmers. In 834, he was made the defender of Luoyang. In 835, he was given the honorary chancellor title of "Zhongshu Ling" (). Later that year, after a major outward clash of between the officials headed by Zheng Zhu and Li Xun and the powerful eunuchs, known as the Ganlu Incident, led to the deaths of four chancellors (Li Xun, Wang Ya, Jia Su, and Shu Yuanyu) and massive eunuch reprisals against those viewed as Zheng's and Li Xun's associates, Pei urged leniency, and it was said that some 10 families were spared because of his efforts.
