The historical position of Zuo Zhuan;
The appearance of Zuo Zhuan marks that the compilation of China's ancient history books has entered a new stage of development.
Zuo Zhuan provides a great deal of important information about the academic history of the Spring and Autumn Period and its previous stages, such as ideological history, economic history, social history and so on, which is unmatched and compared by any other history before or at the same time.
It reliably recorded an important historical stage from the 8th century BC to the 5th century BC, filled the blank, and was valuable for future generations to fully understand the progress of ancient civilization in China.
As a historical work compiled more than 2,000 years ago, another remarkable feature of Zuo Zhuan is that its annotations also reflect the guiding ideology and writing principles with positive significance, thus creating a fine tradition of compiling ancient history books in China.
In the face of all kinds of historical facts, Zuo Zhuan dares to write straight, not empty beauty, not hiding evil. The events and characters recorded in Zuo Zhuan have high historical authenticity.
