Jia Su
After Emperor Wenzong's plot with Li Xun and Zheng (later known as the Ganlu Incident) failed in late 835, with the eunuchs slaughtering a large number of officials, including Li Xun, Zheng, and Li Xun's fellow chancellors Wang Ya, Jia Su, and Shu Yuanyu, Emperor Wenzong came to miss Li Guyan. In spring 836, he recalled Li Guyan from Shannan West to again serve as chancellor and "Menxia Shilang". Soon after becoming chancellor again, he concurred (along with Zheng Tan) in his colleague Li Shi's petition seeking to posthumously restore Song's reputation, and Emperor Wenzong agreed, posthumously restoring Song's titles. In 837, there was a discussion between Emperor Wenzong and the chancellors, in which Li Guyan advocated the merits of commissioning officials according to their abilities, rather than seniority. In 837, Li Guyan was sent out to serve as the military governor of Xichuan Circuit (西川, headquartered in modern Chengdu, Sichuan), continuing to carry the "Tong Zhongshu Menxia Pingzhangshi" title as an honorary title, as well as the mayor of its capital Chengdu. to replace Yang Sifu, who was named chancellor.
