B
Daban town is famous for girls and windmills（风车）, while Loulan is a myth（神话）in the desert. From Daban, we move to another ancient city, Loulan.
Two thousand years ago, beside the beautiful and rich Luobu Lake, there lay Loulan, ancient city on the Silk Road. Businessmen from every country gathered here and there were dancing parties. Everything shows that people in Loulan lived a rich life then.
However, two thousand years later, this rich land suddenly disappeared from the map of China. Then it became an area covered with sand and dead tree trunks.
Loulan was first “discovered” by a Swedish man Sven Hedin in 1900. People from America, Britain, Japan and Sweden, all set foot here. Then in the 1930s, a Chinese named Huang Wenbi came to Loulan for the first time. He visited and studied this area and found many relics that were beautifully and carefully made.

Lying on the northwest of the Lop Nur area, the Loulan Kingdom is now a lifeless area with endless “forests” of mounds（小丘）which aren’t easily seen in other parts of the world. Its mystery (神秘) has been attracting so many people from so many countries.
