Spring and Autumn Annals is a chronicle of Lu, which was revised by Confucius. It recorded the history from the year of Luyin (722 BC) to the fourteenth year of Lu Aigong (4865438 BC+0 BC), and it is the earliest chronological history book in China and one of the Confucian classics. Traditionally, Chunqiu is regarded as the work of Confucius, while some people think it is the collective work of Lu historians.
Sun Tzu's Art of War was written by Sun Wu (word evergreen), a native of the State of Qi at the end of the Spring and Autumn Period.
