Explanation:

The Yellow River is located in Central China and is known as "the cradle of Chinese civilization". Archaeological records show its basin has been inhabited since prehistory by various cultures. The Han civilization, one of the most important civilizations in China, also developed in its basin.

However, the river has also created various difficulties due to flooding and its sudden course changes. For this reason, it was nicknamed "The Sadness of China", due to the various deaths caused by drowning and the loss of crops.

Thus, to cultivate on the basin of the Yellow River a lot of organization was required; to cultivate at the appropriate times, to build dams that would stop the floods, and take advantage of the fertile lands to the maximum.
