, located in the river's last valley before the North China Plain, a great delta created from silt dropped at the Huang He's mouth over the millennia. The North China Plain extends over much of Henan, Hebei, and Shandong provs. and merges with the Chang (Yangtze) delta in N Jiangsu and N Anhui provs. The Huang He meanders over the fertile, densely populated plain to reach the Bohai. The plain is one of China's most important agricultural regions, producing corn, sorghum, winter wheat, vegetables, and cotton.
Its nickname is "Land of the yellow earth."

Historical significance

The geography of the North China Plain has had profound cultural and political implications. Unlike areas to the south of the Yangtze, the plain generally runs uninterrupted by mountains and has far fewer rivers, and as a result communication by horse is rapid within the plain. As a result, the spoken language is relatively uniform in contrast to the plethora of languages and dialects in southern China. In addition the possibility of rapid communication has meant that the political center of China has tended to be located here.

Although the soil of the North China Plain is fertile, the weather is unpredictable, being at the intersection of humid winds from the Pacific and dry winds from the interior of the Asian continent. This makes the plain prone to both floods and drought. Moreover, the flatness of the plain promotes massive flooding when river works are damaged. Many historians have proposed that these factors have encouraged the development of a centralized Chinese state to manage granaries

Granaries are often built above the ground to keep the stored food away from mice and other animals.-Early origins:From ancient times grain...
