Karez is a water conservancy system in the arid area of Xinjiang. It is formed by underground channels connecting wells. The system collects a large amount of rainwater and snow melt water that seep into the ground in spring and summer, and draws it to the ground through the natural slope of the mountain to irrigate farmland and meet people's daily water needs. Karez reduces the evaporation of water on the ground and does little damage to the surface, thus effectively protecting the natural resources and the ecological environment. Kanerjing embodies the wisdom of the harmonious coexistence of our people and nature, and is a great contribution to human civilization.
