Chai Rong, emperor of Later Zhou

Chai Rong (Chinese: 柴榮) (27 October 921 – 27 July 959) or Guo Rong (郭榮), also known by his temple name Shizong (世宗), was the second emperor of imperial China's short-lived Later Zhou during the Five Dynasties and Ten Kingdoms period, reigning from 954 until his death. He succeeded his uncle-in-law Guo Wei, whose surname he had adopted.

Emperor Shizong is considered a highly successful emperor of the Five Dynasties period. He centralized military power by his reforms, and proved his military prowess by a series of victories against Northern Han, Later Shu, Southern Tang, and the Liao dynasty. Although his accomplishments were limited due to his premature death, they paved the way for the eventual unification of large parts of China proper by the Northern Song, founded by his trusted general Zhao Kuangyin.
