How was transportation standardize under the Qin?

Transportation was standardized under the Qin Dynasty through the construction of an extensive network of roads and canals.

One of the key infrastructure construction projects of the Qin Dynasty was the establishment of a standardized road system known as the "Li Bing's Road" or "Qin's Road." This road system spanned across the entire empire, connecting different regions and facilitating trade and communication. The construction of roads allowed for faster and more efficient transportation of goods and military forces.

To ensure uniformity and standardization, the roads were built with consistent width, layout, and construction materials. Stone and gravel were used to reinforce the roads, making them durable and withstand heavy traffic. Regular maintenance and repair of roads were also carried out to ensure their functionality.

In addition to roads, the Qin Dynasty also focused on the construction of canals to improve transportation. The most famous canal built during this period was the Lingqu Canal, which connected the Xiang River and the Li River. This canal facilitated transportation between the regions of the Yangtze River and the Pearl River, contributing to increased trade and economic growth.

The standardization of transportation under the Qin Dynasty played a crucial role in the empire's centralization and efficient governance. It allowed for faster movement of armies, efficient trade and communication, and facilitated the cultural assimilation and control over the newly conquered regions.
