The rise of the Han people in Central Plains increased the efficiency of agricultural production under the artificial control of water conservancy facilities with flat land and abundant rainfall. In the subsequent outward expansion, the emperor, on the basis of such criteria, conquered areas that could be rebuilt according to such criteria instead of being scorched-out. As can be imagined, the same way of thinking lasted for thousands of years.
