launched an invasion against Wu's ally, Shu Han. Wu sent its armies to divert Wei's attention from Shu, but after Shu fell, they attempted to claim Shu's former territories, which ended in failure. Sun Xiu died in September 264. Before his death, he established Guang province with the four commanderies in northern Jiao, namely Nanhai, Cangwu, Gaoliang, and Yulin. Lã Hưng's rebellion inspired Jiuzhen and Rinan to also rebel. Lã Hưng led his troops to Hepu in hopes that the people there would also revolt. After the fall of Shu, he sent his Commandant, Đường Phổ (唐譜; Tang Pu), to Jincheng (進乘; in present-day Pingbian Miao Autonomous County, Yunnan) to reach out to Cao Wei's Chief Controller of Nanzhong, Huo Yi, for help. Huo Yi sent a letter to the Wei capital, Luoyang, to report on the matter and received a reply from the court in September 264. Lã Hưng was appointed the General Who Stabilises the South and Chief Controller of Jiao while Huo Yi was appointed Inspector of Jiao and given discretion over the province. Despite his office, Huo Yi would administer the province remotely from Nanzhong. He requested that a native of Jianning (建寧; around present-day Qujing, Yunnan), Cuan Gu be made Prefect of Jiaozhi, and dispatched him along with many other generals, most of whom formerly served Shu, to help Lã Hưng. However, before Wei forces could arrive, Lã Hưng was assassinated by his Officer of Merit, Lý Tống (李統; Li Tong). Jin's Jiao Campaign (265–268) In 265, Cuan Gu set out from Nanzhong to Longbian County to appease Jiaozhi and the other Wei-aligned territories. In February 266, Sima Yan (Emperor Wu of Jin) established the Western Jin dynasty, replacing Cao Wei. Huo Yi, Cuan Gu and the others thus became Jin subjects. Shortly after Jin formed, Cuan Gu died, so Huo Yi replaced him with Ma Rong (馬融). Later, Ma Rong also died of illness, so he was replaced with Yang Ji. After two years of administration, Jin consolidated its control over Jiaozhi and Jiuzhen, and they were also on the verge of taking Rinan. Jin's success in Jiao supposedly caused widespread unease throughout Wu's domain north of Hepu. First Wu counteroffensive (268) In 268, the Wu emperor, Sun Hao, launched a counteroffensive against Jin to reclaim Jiao. He sent the Inspector of Jiao, Liu Jun (劉俊), the Grand Commander, Xiu Ze (脩則) and the
