Wei Jiansu - During Emperor Suzong's Reign

During Emperor Suzong's Reign

Meanwhile, Li Heng had declared himself emperor at Lingwu (as Emperor Suzong). When Emperor Suzong's messengers reached Emperor Xuanzong, he gave public approval and took the title of Taishang Huang (retired emperor). He sent Wei Jiansu and other chancellors Fang Guan, and Cui Huan to Lingwu to official invest Emperor Suzong as emperor and gave them the imperial seal and the edict officially passing the throne. They encountered Emperor Suzong, who was then launching a counterattack, at Shunhua (順化, in modern Qingyang, Gansu), and they offered the seal and the edict to Emperor Suzong. Emperor Suzong declined, stating that with empire still in turmoil, it was not an appropriate time for him to officially take the throne, instead putting the seal and the edict aside and paying them daily respects, as they represented Emperor Xuanzong.

Meanwhile, though, Emperor Suzong had been impressed with Fang's reputation and therefore particularly honored Fang, giving him most of the responsibilities. In contrast, Emperor Suzong was displeased with how Wei had followed Yang Guozhong's directions and therefore did not pay him much respect, although he allowed Wei to remain chancellor for some time. In spring 757, Wei was made Zuo Pushe (左僕射), one of the heads of the executive bureau, and removed from his chancellor post. He was subsequently made a senior advisor to the crown prince. After Emperor Suzong recaptured Chang'an in fall 757, he sent Wei to Shu to escort Emperor Xuanzong back to Chang'an. After Wei brought Emperor Xuanzong back to Chang'an, he was given the honorific title Kaifu Yitong Sansi (開府儀同三司).

In Emperor Suzong's Shangyuan era (760-761), Wei requested to retire on account of a foot ailment, and Emperor Suzong allowed him to do so. He died around the new year 763, briefly after Emperor Suzong himself had died and been succeeded by his son Emperor Daizong. Wei was given posthumous honors and given an official burial.
