Flaming Mountains(火焰山):
In Chinese, it is pronounced as: huǒ yàn shān，Written as:

Located in the central and northern part of the Turpan Basin in Xinjiang, China, along the northern route of the ancient Silk Road, the Flaming Mountains stretch from east to west. Their intense heat and dryness are attributable to the unique natural geographic conditions of the area. The Flaming Mountains are one of the branches of the Tianshan Mountains, formed during the Himalayan orogeny about fifty to sixty million years ago. Over millions of years, the lateral movements of the earth’s crust created numerous fold belts, which, along with natural erosion from wind and rain, shaped the undulating terrain and the crisscrossing ravines of the Flaming Mountains.
The Flaming Mountains became world-renowned through the famous mythical novel “Journey to the West” by Wu Cheng’en during the Ming dynasty. In “Journey to the West,” Tang Seng and his disciples, on their quest for sacred texts, are blocked by a place called the Flaming Mountains. The mountains unleash fierce flames, not ordinary fire, which can only be extinguished with the Banana Fan, owned by the Bull Demon King and Princess Iron Fan. This leads to the story of “Sun Wukong Borrowing the Banana Fan” three times.
According to “Journey to the West,” the reason the Flaming Mountains spew fire year after year is because, five hundred years earlier, Sun Wukong knocked over Lord Lao’s Furnace. The residual embers from the bricks of the furnace fell to the ground, giving rise to the Flaming Mountains.
