李嗣昭
Li Cunxu himself had, immediately after becoming prince, had to deal with a conspiracy by Li Kening and an adoptive son of Li Keyong's, Li Cunhao (), to overthrow him, but after executing Li Kening and Li Cunhao, he prepared for a campaign to save Li Sizhao. He put Ding Hui in nominal command of the operation, while he himself, Zhou, and Li Siyuan led the main attacks against the Later Liang centipede encampment. They attacked it under the cover of fog, and the Later Liang forces collapsed and fled. When Zhou subsequently arrived at the city walls and announced that the siege had been lifted, Li Sizhao initially did not believe him, but when Li Cunxu subsequently arrived, wearing white armor (thus signifying that Li Keyong had died), Li Sizhao realized what had occurred and fell into deep mourning before opening the gates to let Li Cunxu enter. (Before the battle, Li Cunxu had told Zhou what Li Keyong had said before his death, and Zhou, in response, fought particularly fiercely during the battle. After the battle, he relayed what occurred to Li Sizhao, and the two reformed a friendship.) In the aftermaths of the siege, it was said that Lu had lost over half of its population due to cold and hunger, and the economy had collapsed. Li Sizhao, in response, encouraged farming and caring for silkworms, and lessened the tax burden on the people. It was said that within several years, Lu was back to prosperity.
