The full name of Zuozhuan is Chunqiu Zuozhuan, which is one of the thirteen Confucian classics. Zuo Zhuan is not only a historical masterpiece of ancient Han nationality, but also a literary masterpiece. Zuo Zhuan is China's first detailed chronicle work, which was compiled by Lu historian Zuo Qiuming at the end of the Spring and Autumn Period according to Chunqiu, one of the six Confucian classics. The narrative scope began in the year of Lu Yin (722 BC) and ended in the twenty-seventh year of Lu Aigong (468 BC), which mainly recorded the important political, economic, military, diplomatic and cultural events of various countries in the early years of the Eastern Zhou Dynasty.

Zuo Zhuan is the earliest detailed chronicle of ancient China, with a total of 35 volumes. The full name of Zuozhuan is Chunqiu Zuoshi Zhuan, which was also called Chunqiu Zuoshi in Han Dynasty. It was only after the Han Dynasty that it was called Zuo Zhuan, which was a historical book with comments on Spring and Autumn Annals. Together with Chunqiu Gongyang Biography and Chunqiu Guliang Biography, they are called Chunqiu Sanzhuan. Zuo Zhuan is not only a strategic masterpiece, but also a historical masterpiece. Legend has it that it was written by Zuo Qiuming, a historian of Lu in the late Spring and Autumn Period.

Zuozhuan is 13 years longer than Chunqiu, and the actual chronicle is 26 years longer (the last thing is to mention three schools to destroy Jin). The narrative is based on the chronology of Chunqiu, including some explanations of Chunqiu's calligraphy, some supplements to Chunqiu's classics, and some mistakes in revising Chunqiu's chronology. Most of the books belong to the events in the Spring and Autumn Period, but the completion of the book entered the Warring States Period. All these show the close relationship between Zuo Zhuan and Chunqiu.

Zuo Zhuan is China's first chronicle history book with detailed narration, and it is also one of the thirteen Confucian classics. The authors of Zuo Zhuan, Sima Qian and Ban Gu have all been proved to be Zuo Qiuming, which is the most credible historical data at present. Some scholars think it was written by people in the early years of the Warring States, but they all question it, because the narrative style of some articles in Zuo Zhuan is inconsistent with others, and there is no historical evidence to support it, so it can only be classified as speculation.

The influence of Zuo Zhuan on later generations is first reflected in history. It not only developed the chronological style of Spring and Autumn Annals, but also recorded and preserved a part of the popular practical writing at that time, which provided reference for the development of applied writing in later generations. According to Chen Xun, a poet in the Song Dynasty, there are eight kinds of life, such as oath, alliance, prayer, remonstration, concession, writing and reciprocity, which are far more than these. Later generations believe that prose also originated from Zuo Zhuan. Moreover, this book is of great artistic value in China's literary world and contributes a lot to history!
