Zuo Zhuan , or Chunqiu Zuo Zhuan , sometimes translated as the Chronicle of Zuo or the Commentary of Zuo, is among the earliest Chinese works of narrative history, covering the period from 722 to 468 BC. Most notable modern scholars of this book such as Yang Bojun hold that the work was compiled during the Warring States period, with a compilation date not later than 389 BC. This work and the Shiji or Records of the Grand Historian, were regarded as the ultimate models by many generations of prose stylists in ancient China.
