Why is it said that the Spring and Autumn and Warring States periods formed the "soul" of Chinese culture?

Starting around the Xia Dynasty, China entered the Bronze Age. By the time of the Shang Dynasty, bronze tools were used in almost every aspect of social life. As the sharpness of bronze tools was much better than that of stone tools, and the casting technology at that time could produce a variety of hand tools and agricultural implements suitable for different purposes, which vigorously promoted the development of social production. As a result, cities with large populations emerged. In these cities, huge palaces were built, large royal tombs were constructed, and defense facilities such as walls and ditches were built.

There were carriages and boats connecting the capitals to each other; there were inscribed oracle bones to record social events; and the sciences of astronomy, calendaring, and medicine were developed. Bronze tools were used in the mining industry to extract more ores. The development of the smelting industry, in turn, prompted the development of the bronze casting industry. This virtuous circle led to the full development of the Bronze Age in China.

The splendid bronze culture it created occupies a unique position in the world's cultural heritage.
