Trade, Cities, and the Growth of the Economy
Agricultural production was only one part of the transformation.

Cities developed into political, military, and commercial centers.
Craft production expanded.
Bronze casting, pottery, textiles, woodworking, and other forms of specialized production supported both ordinary life and elite consumption.
The development of roads and waterways also made it easier to move people, food, raw materials, and military supplies.
Economic exchange gradually became more sophisticated, and forms of coinage appeared in different regions of China.
These changes were not identical everywhere, nor did they happen simultaneously.
But together they reveal a broader transformation:
China was becoming an increasingly interconnected economic world even as it remained politically divided.
