What is the watershed between the Yangtze River system and the Yellow River system?

The watershed between the Yangtze River system and the Yellow River system is the Qinling Mountains, which is about 1.600 km long. It is the watershed between Weihe River, a tributary of the Yellow River, and Jialing River and Hanshui River, a tributary of the Yangtze River.

The main peak of Qinling Mountains and Taibai Mountain is 377 1.2m above sea level. These peaks are more than 2000 meters above sea level. Qinling Mountain can block the winter wind from going south, which is an important dividing line of China's physical geography.
