During the Spring and Autumn and Warring States periods, Chinese society entered a golden age of free thinking and a proliferation of competing academic schools flourished. The field of geography at that time also ushered in unprecedented rapid development, with the emergence of several milestone geographical works that laid the preliminary theoretical and practical foundations for various branches of the discipline. It can be said that this period was the first peak in the development of ancient Chinese geography and the start of building the essential framework for the ancient system of geoscience.
