The Minjiang River, a tributary of the upper reaches of the Yangtze River, not only has the effect of preventing floods and disasters, but is also a wonder in the history of world water conservancy projects.

Landscape of the middle reaches of the Yangtze River. The Yangtze River is the "golden waterway" that runs from east to west in my country.

The landscape of the upper reaches of the Yangtze River is located between the first ladder and the second ladder in my country. The terrain changes greatly, and the water flows deeply into the cross-cutting mountains, forming steep and spectacular canyons.
