Hongqi Canal is a great project, with a total length of 65,438+0,500 kilometers, involving nearly 654,380+million people and taking nearly 65,438+00 years. It is a miracle of new China, and is known as the eighth wonder of the world.

The total length of the main canal is 70.6 kilometers, the bottom of the canal is 8 meters wide, the wall of the canal is 4.3 meters high, the longitudinal slope is 1/8000, and the designed maximum flow is 23 cubic meters per second. All the canals are dug in the waist of Taihang Mountain, where the peaks and peaks overlap. This project is both difficult and dangerous.
