Abstract: The transition from the Spring and Autumn Period to the Warring States Period was an important watershed in the development of traditional Chinese history and culture. The transition from the Zhou Dynasty's feudal system to a monarchy state after the collapse of the feudal system can be seen as a shift from classicism to "modernity" under the framework of the big history. The changes from the Spring and Autumn Period to the Warring States Period determined the basic trajectory of the subsequent development of traditional Chinese history. The Chinese traditional society after the Warring States Period was essentially a "modern society" at the philosophical and cultural level, with the rise of secularism, materialism and individualism. The cultural significance of "modernity" has important reference and practical significance for the present.

Key words: The Warring States Period, change, modernity, cultural significance
