What outstanding historical traditions did Confucius create in the ancient history of China?

Confucius wrote Spring and Autumn Annals.

Left a historical tradition of "all talk and no action"

The so-called "all talk and no action" means:

Writing history books is completely described from an objective standpoint, without personal feelings, and everything is left to the readers to experience.

This tradition has been circulating for a long time, which prevents the author from deliberately belittling or praising someone and ensures the principle of justice in history books.
