The city's name is often confused with the Yumen Guan or Jade Gate which is the frontier-pass of ancient times, the entrance to the old Silk Roads, which was situated not far to the west of Dunhuang. Although both Yumen City and Yumen Gate are within Jiuquan, the latter is some 400 kilometres (250 mi) to the west from the former.
In 2014, areas of the city were sealed off after a resident died of the bubonic plague. Districts of the city which house up to 100,000 were turned into quarantine zones. The city allocated 1 million yuan to be used for emergency vaccinations.[2]
History edit
The site of Yumen was brought under Chinese control around the end of the 2nd century BCE. Yumen was known as 'Huiji' in the 5th century when the area was reclaimed by the Northern Wei dynasty (386–534/535) and was soon after renamed back to Yumen in 581. Under the Tang dynasty (618–907), Yumen's county seat was located at Chijinzhen which is east of the present Yumen City. The city was then under Tibetan control around 770 CE for some 70 years. After the Tang dynasty, Yumen became a part of the Western Xia (1038–1227). During the Ming dynasty (1368–1644), the area came under Tibetan control again and was only reestablished later on in the early Qing dynasty (1644–1912).[3]
In 1939, the first oilfield in China was established at Yumen.[3]

Economy edit
The overland route to Western Asia from China flourished until the end of the Tang dynasty. Furthermore, due to increased use of sea transportation, Yumen became a backwater.
There were two catalysts for Yumen's rapid revival in the 1930s and 40s. The construction of a modern highway over the old caravan route from Yumen to Ürümqi (capital of the Uygur Autonomous Region of Xinjiang) and continuing on-wards to Kazakhstan. The railway of Yumen is the linking point of the railway line between Lanzhou (capital of Gansu) and Ürümqi.
After the discovery of oil in the Jiuquan basin, to the north of the Qilian Mountains the city's economy was given another major push. The first oil was drilled at Laojunmiao near Yumen in 1939 where an appreciable production was achieved in 1941. Only until 1949 did large-scale development begin, and prospecting in 1950 revealed much larger reserves than had been speculated. Yumen has its own refinery but is also linked by pipeline to a refinery at Lanzhou. Other than oil drilling and refining, Yumen also has thermal and wind power-generating facilities. Manufacturing includes machinery, building materials, chemical fertilizers and process agricultural products.[3]
China appears to be constructing 120 missile silos near Yumen.[5]
