The campaign to destroy Later Liang In spring 923, Li Cunxu, then at Wei Prefecture (魏州, in modern
Handan,
Hebei, renamed Xingtang () shortly after), declared himself the emperor of a new
Later Tang (as Emperor Zhuangzong). He commissioned Guo Chongtao and a senior eunuch,
Zhang Juhan, as chiefs of staff (now with the title changed to
Shumishi). (The new emperor also summoned Li Shaohong back from Lulong, but with the ambitious Guo not wanting Li Shaohong, whom he had previously served under, becoming chief of staff again (since Li Shaohong would effectively be more senior than he was), Guo dissuaded Emperor Zhuangzong from making Li Shaohong chief of staff and recommended Zhang instead; this incident caused Li Shaohong, who was instead made the director of palace affairs, resentful of Guo.) Meanwhile, the official
Kong Qian, who had long been overseeing the responsibility of supplying the Jin forces, wanted to be the director of material pricing (i.e., overseeing the three financial agencies in charge of taxation, treasury, and salt and iron monopolies), but the other officials opined that Kong lacked a lengthy career and came from low birth, and so Guo recommended the senior official Zhang Xian () instead, having Kong made Zhang Xian's deputy; this also displeased Kong. Despite the declaration of himself as emperor, Emperor Zhuangzong was actually facing some difficult times at that time—it was said that due to frequent Khitan pillaging incursions, Lulong lacked sufficient food supplies; meanwhile, a recent Later Liang counterattack had caused Later Tang to lose Wei Prefecture (衛州, in modern
Puyang,
Henan, not the same Wei Prefecture where Emperor Zhuangzong was at that time) to Later Liang; further,
Li Jitao the military governor of Anyi Circuit (安義, i.e., Zhaoyi, as he was the son of Emperor Zhuangzong's deceased cousin
Li Sizhao and the circuit was therefore renamed to observe
naming taboo for Li Sizhao) had also rebelled and submitted to Later Liang. The Later Tang morale was thus low at the time. However, at that time, the Later Liang officer Lu Shunmi () of Tianping Circuit (天平, headquartered in modern
Tai'an,
Shandong) defected to Later Tang and exposed the fact that Tianping's capital Yun Prefecture (), deeply inside Later Liang territory south of the
Yellow River (which formed the de facto boundary between Later Tang and Later Liang at that time, notwithstanding Later Tang's recent loss of Wei Prefecture and Anyi Circuit, both of which were north of the Yellow River), was poorly defended, with its military governor
Dai Siyuan serving as the overall commander of Later Liang forces against Later Tang at that time and therefore away from the circuit. When Lu further suggested a surprise attack on Tianping, Guo opposed, finding the plan too risky. However, Emperor Zhuangzong's adoptive brother
Li Siyuan advocated for the plan, believing that to break the stalemate with Later Liang, a risky move was necessary. Emperor Zhuangzong thus commissioned Li Siyuan to carry out the attack, and Li Siyuan subsequently captured Yun Prefecture in a surprise attack. After Emperor Zhuangzong shortly after offered sacrifices to heaven and earth at
Luoyang (which he made his capital), he created Guo the Duke of Zhao Commandery, and also granted Guo an iron certificate pre-pardoning him from death 10 times. Meanwhile, Guo had previously had a reputation for complete honesty and not accepting bribes, He ordered that Guo be properly reburied at Taiyuan and that a mansion be granted to his widow Lady Zhou at Taiyuan. As Guo Tinghui and Guo Tingrang each had a young son who were hidden by their relatives and escaped death, these grandsons of Guo Chongtao's were given to Lady Zhou to be raised. == Notes and references ==
