What is the mysterious Xixia civilization under the cover of the desert, the Black Water City?

Heishui Town used to be an important frontier fortress, but it was abandoned due to the diversion of Heishui River, war and other factors. Because of the drought and lack of rain here, the cultural relics were completely protected. However, at the end of the Qing Dynasty, the great powers forcibly opened the door to China, and carried out robbery against some cultural relics in China? Excavate? So many cultural relics have been stolen here, and many cultural relics and documents have been lost overseas, which is really a pity.

Black Water City is also called Black City. It was named Black Water City because it was located on the former Black Water River, which has long since become a desert. It used to be an area rich in water and grass, so in ancient times, ancestors lived and cultivated here. Because of its convenient transportation, it is also a place that everyone competes for in the later period. Black Water City was first established in the Xixia period, when the Xixia Dynasty set up a "Black Water City" here in order to control this area. Yanjunsi of Heishui Town? . At that time, the Black Water City was one of the important frontier defense lines of Xixia.

Later, the Mongols attacked Xixia and occupied this place. Mongolia did not abandon this city, but put more efforts into development. The rulers of the Yuan Dynasty sent a large number of troops to station here and moved people here, making the Black Water City develop into an important town integrating economy, culture and politics, which is very prosperous. There are temples, schools, post stations, hotels, restaurants, money houses and other facilities in the city, which can be said to be a very prosperous town.

however, since 135, the situation here has changed. Perhaps it is because the water volume of Heishui River is getting less and less, or perhaps it is because human activities have destroyed nature, and the once lush oasis has become a vast desert. Black Water City was abandoned, leaving only fragments, pagodas and human bones in the city. A prosperous town has gradually become so desolate and embarrassing. It wasn't until the early 2th century that the Russian kozlov carried out three bandit-like excavations on the Black Water City and transported a large number of cultural relics back to their countries for exhibition, and the Black Water City once again appeared in everyone's eyes.
