What river did Chinese civilization develop by?

The Yangzi River and Yellow River

Two great rivers flow from west to east in China. The Huang He, or Yellow River, stretches for nearly 3,000 miles across northern China. The river often floods, and the floods leave behind layers of silt on the surrounding countryside. Because these floods can be very destructive, the river is sometimes called "China's Sorrow." Over the years, millions of people have died in Huang He floods.
To the south, the Chang Jiang, or Yangzi River, cuts through central China. It flows from the mountains of Tibet to the Pacific Ocean. The Chang Jiang is the longest river in Asia.
In early China, the two rivers helped link people in the eastern part of the country with those in the west. At the same time, the mountains between the rivers limited contact.
