himself emperor and founded the state of Shu Han. He promoted Zhang Fei to General of Chariots and Cavalry () and Colonel-Director of Retainers (), and enfeoffed him as the Marquis of Xi District (). Liu Bei sent an imperial edict to Zhang Fei as follows: Death Earlier in late 219, Sun Quan broke his alliance with Liu Bei and sent his general Lü Meng to lead an invasion of Liu Bei's territories in Jing Province, which resulted in the death of Guan Yu. Around July or August 221, Liu Bei launched a campaign against Sun Quan to take revenge and seize back his territories in Jing Province. Zhang Fei was ordered to lead 10,000 troops from Langzhong to rendezvous with Liu Bei's main force at Jiangzhou. During the mobilisation, Zhang Fei's subordinates Fan Qiang () and Zhang Da () assassinated their commander, decapitated the corpse, and brought the head along with them as they defected to Sun Quan's side. When Liu Bei heard that Zhang Fei's adjutant had sent him a report, he exclaimed: "Oh! (Zhang) Fei is dead." In October or November 260, Liu Bei's son and successor Liu Shan granted Zhang Fei the posthumous name "Marquis Huan" (). Family and descendants In the year 200, Zhang Fei chanced upon Xiahou Yuan's niece while she was out gathering firewood and abducted her. She was around 13 years old at the time. Zhang Fei knew that she was of good upbringing, so he married her. She bore him two daughters, who both later married Liu Shan and became known as Empress Jing'ai of the state of Shu. Empress Jing'ai had a younger sister who also married Liu Shan and was known as Empress Zhang. Zhang Fei's eldest son, Zhang Bao, died at a young age. Zhang Bao's son, Zhang Zun (), served as a Master of Writing (). In 263, during the Conquest of Shu by Wei, he followed Zhuge Zhan to defend Mianzhu from the Wei general Deng Ai but was killed in action. Zhang Fei's second son, Zhang Shao (), inherited his father's marquis title and served as a Palace Attendant () and Supervisor of the Masters of Writing () in Shu. In 263, the Shu emperor Liu Shan ordered Zhang Shao, Qiao Zhou and Deng Liang () to represent him when he officially surrendered to Deng Ai and brought an end to the Shu regime. After
