The Yangtze, Yangzi, or officially Chang Jiang is the longest river in Asia, the third-longest in the world and the longest in the world to flow entirely within one country. It rises at Jari Hill in the Tanggula Mountains and flows 6,300 km in a generally easterly direction to the East China Sea.

The video shows a ship sailing in the Xiling Gorge of the Three Gorges of the Yangtze River in Yichang, Hubei Province, China. The Yangtze River Navigation Administration of the Ministry of Transport will carry out the action of sealing the direct discharge valves of domestic sewage and oil sewage in the three gorges reservoir area, which is an ecologically sensitive water area, and implement the "zero discharge" plan of "storage on board and disposal on shore".
