Yumen

Yumen is a prefecture-level city in the northwestern Gansu Province of China. It is situated in the Hexi Corridor, a historically significant route connecting China to Central Asia. The city's name, "Yumen," translates to "Jade Gate" or "Jade Gate Pass," referring to its historical role as a crucial gateway on the Silk Road. This ancient pass was a vital point for trade and cultural exchange for centuries.

The economy of Yumen has historically been tied to its strategic location. In more recent times, it has become known for its petroleum industry. The Yumen Oilfield, discovered in 1939, was one of China's earliest and most significant oil production bases, playing a vital role in the country's industrial development. Beyond oil, agriculture is also practiced in the region, with crops suited to the arid climate.

Geographically, Yumen is characterized by its desert and arid steppe landscapes. It lies at the foot of the Qilian Mountains to the south. The city experiences a continental climate with significant temperature variations between seasons. Yumen is an administrative center and a transportation hub within its region, connecting to other parts of Gansu and neighboring Xinjiang.
