the Prince of Jiyin, and moved him to Cao Prefecture, under secure guard. (He would, however, have the Prince of Jiyin poisoned in 908.) He posthumously honored his parents, as well as ancestors up to four generations, as emperors and empresses. He made Jing Xiang his chief advisor, making decisions in conjunction with Jing before having Jing announce them to the chancellors. Most circuits around the former Tang realm reacted to the transition by submitting to the new emperor's authority. The only exceptions were regions controlled by Li Keyong (thereafter becoming known as Jin), Li Maozhen (thereafter becoming known as Qi), Yang Xingmi's son and successor Yang Wo (thereafter becoming known as Wu), and Wang Jian (thereafter becoming known as Former Shu). Li Keyong, Li Maozhen, and Yang continued to observe the Tang era name of Tianyou, thus acting as if they were still part of the defunct Tang state, while Wang shortly after declared himself the emperor of a new Former Shu state. Liu Rengong initially did not react; however, shortly after, he was put under house arrest by his son Liu Shouguang, who took over Lulong; both Liu Shouwen, who thereafter launched a campaign to try to free his father against his brother Liu Shouguang, and Liu Shouguang nominally submitted to Later Liang. Shortly after becoming emperor, apparently intending to deal a crippling blow to Jin, Emperor Taizu sent Kang Huaizhen north to put Lu Prefecture, then under the command of Li Sizhao, under tight siege; he later went to Lu himself to reinforce the siege. Li Keyong initially sent Zhou Dewei to try to lift the siege, but was unable to do so. In spring 908, Li Keyong himself fell deathly ill, forcing Zhou to withdraw back to Taiyuan. Li Keyong died shortly after and was succeeded by his son Li Cunxu. Emperor Taizu, believing that Lu would fall easily in the aftermaths, not only withdrew himself but also withdrew part of the siege army, under the command of Liu Zhijun, to guard against a potential Qi attack. Li Cunxu, realizing that the Later Liang army had been weakened, launched a surprise assault on the Later Liang army sieging Lu, crushing it and lifting the siege, thus stabilizing the security of the Jin state. When Emperor Taizu received news of the death, he lamented: In 909, Emperor Taizu moved the capital from Daliang to Luoyang, leaving his
