Introduction to the ancient Loulan City model: Ruoqiang was originally "婼Qiang", which is the name of an ancient country. It was first seen in the Western Han Dynasty (36 BC) and was one of the thirty-six kingdoms. In the fourth year of the Yuan Dynasty (176 BC) by Emperor Wen of the Han Dynasty, it became the "Loulan" country. In 108 AD (the third year of the Yuan Dynasty), it surrendered to the Han and the neighboring Xiongnu. In the museum, there is also a model of the ancient country of Loulan, which is based on the three existing rooms in the Loulan ancient city ruins.
