Dujiangyan sends a circle of friends.

Dujiangyan's circle of friends said this:

Dujiangyan is a magnificent project, which witnessed the wisdom and courage of ancient humans. The river flowing for thousands of years tells the story of the years.

When I came to Dujiangyan, I was shocked by its natural beauty. This ancient water conservancy project not only shows the wisdom of the ancients, but also provides us with a livable environment.
