Sun Xiu (235 – 3 September 264), courtesy name Zilie, formally known as Emperor Jing of Wu, was the third emperor of the state of Eastern Wu during the Three Kingdoms period of China. Early life Sun Xiu was born in 235 to Wu's founding emperor, Sun Quan, and one of his concubines, Consort Wang. He was Sun Quan's sixth son. In his youth, he was praised for his studiousness. About 250, Sun Quan arranged for a marriage between Sun Xiu and Lady Zhu, the daughter of Sun Quan's daughter Sun Luyu and her husband Zhu Ju. In 252, just before Sun Quan's death, he enfeoffed Sun Xiu as the Prince of Langya, with his princedom at Hulin (虎林; in present-day Chizhou, Anhui).

Sun Xiu began to fear for his own safety, so he sent his wife Princess Zhu back to the imperial capital Jianye and offered to divorce her, but Sun Jun declined his request and sent Princess Zhu back to Sun Xiu. In November 258, after a failed coup against the regent Sun Chen (Sun Jun's cousin and successor), Sun Liang was deposed and replaced with Sun Xiu as the new emperor of Wu. Coup against Sun Chen After his accession, Sun Xiu ordered five new counties to be added to Sun Chen's marquisate to appease him, in addition to enfeoffing Sun Chen's brothers as marquises too. However, Sun Chen soon fell out with Sun Xiu over a relatively small incident – he brought food and wine to the imperial palace and asked the emperor to dine with him, but the emperor refused.
