Xining

Xining[a] is the capital of Qinghai province in western China[4] and the largest city on the Tibetan Plateau. The city lies in the Huangshui River Valley, also known as Tsongkha (Tibetan: ཙོང་ཁ་), and owing to its high altitude, has a cool climate on the borderline between cool semi-arid and dry winter humid continental. It was a commercial hub along the Northern Silk Road's Hexi Corridor for over 2000 years, and was a stronghold of the Han, Sui, Tang, and Song dynasties' resistance against nomadic attacks from the west. Although long a part of Gansu province, Xining was added to Qinghai in 1928. Xining holds sites of religious significance to Muslims and Buddhists, including the Dongguan Mosque and Kumbum Monastery. It is connected by the Qinghai–Tibet railway to Lhasa, Tibet and connected by a high-speed railway to Lanzhou, Gansu and Ürümqi, Xinjiang.
