Why is it called Turpan Basin?

According to The Journey to the West's book, it is difficult for Tang Priest and his disciples to walk through the "Flame Mountain" on their way to the Western Heaven to learn Buddhist scriptures. The Monkey King borrowed a banana fan from Princess Tiefan. The banana fan put out the fire and set foot on the road to the west again. Does the Flame Mountain depicted in the book exist? In fact, this fiery "Flame Mountain" refers to the Turpan Basin in China. There is no fire in Turpan basin. Why does the book say "Flame Mountain"?

As we all know, Turpan basin is a basin in Tianshan Mountains, with an altitude of-155 meters. The climate there is dry and the temperature rises very high in the hot sun in summer. Moreover, the subsidence of the basin is deep, and hot air is not easy to disperse, so the average maximum temperature in June-August is above 38℃, and it will be above 40℃ for about 40 days, and the maximum temperature is as high as 48.9℃. The highest surface temperature in summer is 70℃. The surface temperature of the desert can reach 82.3℃, so there is a saying that "roast chicken eggs in the sand and bake cakes on the Gobi desert". In addition, there is a kind of red sandstone lying in Turpan basin, which makes the surrounding area appear red in the hot summer sun. Extremely hot temperature, scalding surface temperature and red light are mixed together to form a veritable "Flame Mountain".
