Explanation:

The greatest canal built under Qin Shi Huangdi was the Lingqu Canal, which was built to transport supplies for the army. It connected two major rivers and allowed Qin Shi Huangdi's empire to expand in the southwest. A common Chinese saying is, "In the North there is the Great Wall; in the South there is the Lingqu canal."
