Humans learn to record their own history with words or pictures, and many nationalities in the world, including Mayan civilization, etc. Archaeologists can find clues in the remains of this civilization. Archaeologists believe that in addition to the civilizations we know now, there have been four generations of civilizations in the world, namely Maya civilization, Sanxingdui civilization in China, ancient Egyptian civilization and Atlantis civilization.

Among them, the Mayan civilization is the most mysterious, because four of the five predictions left by the Mayans have been realized. However, with the in-depth development of archaeology, it is found that there is an extremely mysterious civilization circulating in the western regions of China, and their history can even be compared with Mayan civilization.

This once famous ancient civilization is "Loulan". No one knows what the real ancient country of Loulan looks like, but this does not prevent people from being full of expectations for the ancient country of Loulan. Archaeologists even used computers to restore the glorious scene of the ancient country of Loulan at that time.

The ancient city of Loulan is a world-famous and important relic. Located in the west of Lop Nur, it is an important transportation hub of the Silk Road and a relic of the Western Regions. According to historical records, the ancient country of Loulan was founded in A.D. 176. China's silk, tea, horses, grapes and jewels in the western regions are all traded through Loulan.

In Historical Records Biography of Dawan and Hanshu Biography of the Western Regions, the ancient city of Loulan was once called "a country with walls", and Loulan was also one of the 36 powerful countries in the Western Region. Connected with Dunhuang, it is between Han and Xiongnu, but because of its strong national strength, even Xiongnu, who was famous for its bravery at that time, did not dare to cross the Loulan border.

But now, only broken walls is left in this once prosperous country. Archaeologists reconstructed the picture of Loulan at that time according to the remaining buildings. The ancient city of Loulan is square, with an area of about100000 square meters, but now it has become lifeless, especially desolate and tragic.

The reason for its decline is nothing more than war or natural disasters. Scientists believe that the drought at that time was the main reason for the disappearance of Loulan. In the 6th century AD, the lakes in Lop Nur showed signs of moving northward, and the increasingly arid environment caused the Loulan people to lack water and food. As a result, residents had to give up this land and move to other places.
