Former Shu. As part of the attack, he assigned Gao the task of capturing three of Former Shu's eastern prefectures on the border with Jingnan Circuit, Kui (), Zhong (), and Wan () (all in modern Chongqing). Gao left Gao Conghui in charge of the Jingnan headquarters and attacked west, but was defeated by the Former Shu general Zhang Wu () and forced to return to Jingnan's capital Jiangling Municipality. (Zhang later surrendered his territory to the overall Later Tang commander Li Jiji, not to Gao Jixing.) In 926 — by which time Former Shu had fallen to Later Tang, but Later Tang itself was then overrun with mutinies — Li Cunxu was killed in a mutiny at Luoyang, and his adoptive brother Li Siyuan succeeded him as emperor. Gao Jixing requested that Kui, Zhong, and Wan become part of his territory, and Li Siyuan initially agreed. However, when the imperial government would not agree to Gao's demand that he himself be allowed to commission those prefects without imperial agreement, Gao seized Kui by force — effectively rebelling against the Later Tang imperial government. Gao Conghui was said to have repeatedly urged Gao Jixing against rebelling against Later Tang, but Gao Jixing did not listen. Subsequently, during his (successful) resistance campaign against the Later Tang army sent against him, Gao instead submitted to Wu as a vassal — an overture that Wu initially rejected but later accepted. Apparently as part of Gao's submission to Wu, Gao Conghui was given the title by Wu's emperor Yang Pu of military governor of Zhongyi Circuit (忠義, headquartered in modern Xiangyang, Hubei, then under Later Tang control); Yang also gave him the honorary chancellor designation Tong Zhongshu Menxia Pingzhangshi (). Reign During Later Tang Around the new year 929, Gao Jixing fell ill, and put Gao Conghui in charge of Jingnan's headquarters. Gao Jixing died shortly after. Yang Pu thereafter gave him the title of military governor of Jingnan, and bestowed on him the greater honorary chancellor title of Shizhong (). Upon his assumption of Jingnan's governance, however, Gao Conghui believed that it was inadvisable to continue to be inimical to Later Tang and be a vassal to Wu, pointing out that Wu's main territory was much farther away than Later Tang. He therefore, through his southern neighbor Ma Yin the King of Chu, offered apologies to Li Siyuan, and later also made the
