There are two major river systems that provide fresh water to the vast agricultural regions of the central part of China Proper. They flow from the Tibetan Highlands to the East China Sea and Yellow Sea. These rivers are:

The Yellow River (Huang He River) and The Yangtze River (Chang Jiang River).

Explanation:

The Yellow River and The Yangtze River are the two river systems that produce freshwater to the farming regions of China.

The Yellow River got its name after the sand that washes into the river. The river flows from the Tibetan mountains the goes into the Yellow Sea. Canals, dams, and irrigation projects provide water for agriculture. Farmers grow crops like sorghum, wheat, corn, soybeans, and vegetables.

The Yangtze River runs out of the Tibetan Plateau and at last, falls into the East China Sea. Agriculture includes farming of wheat and rice. This river follows from the Sichuan Province and moves to the Three Gorges region.
