It is considered 'Ly Ly School in Underground', why Chinese people are also less knowledgeable about this project.0: 00/2: 04 Southern domains mentioned the great Chinese buildings to leave , posteround can think immediately to the thousands of schools built by Qin Thuy Hoang, with a huge resume and material. However, there is a building that can match the Great Wall, it has existed more than 2,000 Year and raising thousands of Chinese people, which is Karez underground channel in Xinjiang. In the Karez underground channel system (Source: Sohu) drought has long been a problem that causes Xinjiang farmer headache . Xinjiang areas are located on a plateau, the sun is fiercely causing the amount of evaporating water farout the rainfall
. Whether the rainy season, Xinjiang crops are difficult to develop green well. His harshness has turned Xinjiang into a barren land so people living here often in hunger. Noticing the inadequate issue here, Emperor Han De De (156 BC - 87 BC) ordered the construction of the Karez groundwater system to support agricultural development
Dao Xuyen Xuyen Mount Karez - Great Wall Earth (Source: Sohu) Taking advantage of melting water in the summer of snow mountains and glaciers in Xinjiang, workers dug a channel lead at the foot of snow mountains and link these channels With the glaciers to create the underground channel system Karez.When the water flows into the underground channel system, people will dig deep wells to get water to use. The channel is also dug deep into the ground, so it avoids evaporating water in the summer. The operation of the underground channel system Karez (Source: Smithsonian) After Karez completed, the problem of water shortage and drought of farmers In Xinjiang has been resolved, and their lives like stepping into a new page. QUA time, channel length and the number of wells is increasing. Up to now, the channel length has doubled the length of the length of the world, equivalent to 5,000 km, the number of wells is dug up to 1700 wells. The wells are deepened to get water (source: kknews) Constructing the same time with the Greatgesis, the role of Karez is to help develop agriculture, not a tourist attraction so far the existence of the giant canal system is not well known, told Both the Chinese. Thanks to the appearance of this irrigation project, the Turpan region, Xinjiang has become one of the largest green grape production places in the world. Rolled products here have a special sweet taste thanks to the cooling water from the mountain flowing through the ancient tunnel system.Theo Kim Dung / Fatherland newspaper
