Tibetan pinyin in the context of "Ngari Prefecture"

The Tanggula (Chinese: 唐古拉山, p Tánggǔlāshān, or 唐古拉山脉, p Tánggǔlāshānmài), Tangla, Tanglha, or Dangla Mountains (Tibetan: གདང་ལ་།, w Gdang La, z Dang La) is a mountain range in the central part of the Qinghai-Tibet Plateau in Tibet. Administratively, the range is in the Nagqu Prefecture of the Tibet Autonomous Region, with the central section extending into the Tanggula Town and the eastern section entering the Yushu Tibetan Autonomous Prefecture of Qinghai province.

Tanggula is the source of the Ulan Moron and Dam Qu Rivers, the geographic headwaters of the Yangtze River. It functions as a dividing range between the basin of the Yangtze in the north and the endorheic basin of northeastern Tibet in the south.

The Yarlung Tsangpo, also called Yarlung Zangbo (Tibetan: ཡར་ཀླུངས་གཙང་པོ་, Wylie: yar kLungs gTsang po, ZWPY: Yarlung Zangbo) and Yalu Zangbu River (Chinese: 雅鲁藏布江; pinyin: Yǎlǔzàngbù Jiāng) is a river that flows through the Tibet Autonomous Region of China and Arunachal Pradesh of India. It is the longest river of Tibet and the fifth longest in China. The upper section is also called Dangque Zangbu meaning "Horse River".

Originating from the Angsi Glacier in western Tibet, southeast of Mount Kailash and Lake Manasarovar, it later forms the South Tibet Valley and Yarlung Tsangpo Grand Canyon before passing into the state of Arunachal Pradesh in India. Downstream from Arunachal Pradesh, the river becomes far wider and is called the Siang. After reaching Assam, the river is known as the Brahmaputra.

Bon or Bön (Tibetan: བོན་, Wylie: bon, ZWPY: Pön, Lhasa dialect: [pʰø̃̀]), also known as Yungdrung Bon (Tibetan: གཡུང་དྲུང་བོན་, Wylie: gyung drung bon, ZWPY: Yungchung Pön, lit. 'eternal Bon'), is the indigenous Tibetan religion which shares many similarities and influences with Tibetan Buddhism. It initially developed in the tenth and eleventh centuries but retains elements from earlier Tibetan religious traditions. Bon is a significant minority religion in Tibet, especially in the east, as well as in the surrounding Himalayan regions.

The relationship between Bon and Tibetan Buddhism has been a subject of debate. According to the modern scholar Geoffrey Samuel, while Bon is "essentially a variant of Tibetan Buddhism" with many resemblances to Nyingma, it also preserves some genuinely ancient pre-Buddhist elements. David Snellgrove likewise sees Bon as a form of Buddhism, albeit a heterodox kind. Similarly, John Powers writes that "historical evidence indicates that Bön only developed as a self-conscious religious system under the influence of Buddhism".

Lha-bzang Khan (Mongolian: ᠯᠠᠽᠠᠩ ᠬᠠᠭᠠᠨ Lazang Khaan; Tibetan: ལྷ་བཟང༌, ZWPY: Lhasang; alternatively, Lhazang or Lapsangn or Lajang; d.1717) was the ruler of the Khoshut (also spelled Qoshot, Qośot, or Qosot) tribe of the Oirats. He was the son of Tenzin Dalai Khan (1668–1701) and grandson (or great-grandson) of Güshi Khan, being the last khan of the Khoshut Khanate and Oirat King of Tibet. He acquired effective power as ruler of Tibet by eliminating the regent (desi) Sangye Gyatso and the Sixth Dalai Lama, Tsangyang Gyatso, but his rule was cut short by an invasion by another group of Oirats, the Dzungar people. At length, this led to the direct involvement of the Chinese Qing dynasty in the Tibetan politics.

Nagqu (also Naqu, Nakchu, or Nagchu; Tibetan: ནག་ཆུ།, Wylie: Nag-chu, ZWPY: Nagqu; Chinese: 那曲; lit. 'black river') is a prefecture-level city in the north of the Chinese autonomous region of Tibet. On May 7, 2018, the former Nagqu Prefecture was officially declared the sixth prefecture-level city in Tibet after Lhasa, Shigatse, Chamdo, Nyingchi and Shannan. The regional area, covering an area of 450,537 km (173,953 sq mi), is bordered by Bayingolin and Hotan Prefectures of Xinjiang to the north, Haixi, Yushu Prefectures of Qinghai and Chamdo to the east, Nyingchi, Lhasa and Shigatse to the south, Ngari Prefecture to the west. As of the 2010 census, it had a population of 462,381. Since its official establishment in 2018, it is the largest prefecture-level city by area in the world, being slightly larger than Sweden.According to the population sampling survey, the resident population of the city by the end of 2024 will be 514,300.

Nagqu contains 89 townships, 25 towns, and 1,283 villages. The main city of Nagqu is along the China National Highway 109, 330 kilometres (210 mi) northeast of Lhasa. Amdo, Nyainrong and Xainza are other towns of note. Extremely rich in water resources, with 81% of Tibet's lakes, covering a total area of over 30,000 square kilometres (12,000 sq mi), it contains lakes such as Namtso, Siling Lake and rivers such as Dangqu.

Yushu Tibetan Autonomous Prefecture (Tibetan: ཡུལ་ཤུལ་བོད་རིགས་རང་སྐྱོང་ཁུལ།, ZWPY: Yüxü Poirig Ranggyong Kü, Chinese: 玉树藏族自治州; pinyin: Yùshù Zàngzú Zìzhìzhōu, retranscribed into Tibetan as ཡུལ་ཤུལ།), also transliterated as Yüxü or Yulshul, is an autonomous prefecture of Southwestern Qinghai Province, China. Largely inhabited by Tibetans, the prefecture has an area of 188,794 square kilometres (72,894 sq mi) and its seat is located in the town of Gyêgu in Yushu County, which is the place of the old Tibetan trade mart of Jyekundo. The official source of the Yellow River lies within the prefecture. Historically, the area belongs to the cultural realm of Kham in Eastern Tibet.

On 14 April 2010, an earthquake struck the prefecture, registering a magnitude of 6.9 (USGS, EMSC) or 7.1 (Xinhua). It originated in the Yushu Tibetan Autonomous Prefecture, at 07:49 local time.

The Ulan Moron (Mongolian: ᠤᠯᠠᠭᠠᠨᠮᠥᠷᠡᠨ, Ulaan Mörön, lit. "Red River"; Chinese: 乌兰木伦, p Wūlánmùlún), Mar Qu (Tibetan), or Tuotuo River (沱沱河, p Tuótuó Hé, lit. "Tearful River"; Tibetan: ཐོག་ཐོག་ཆུ་, ZWPY: Togtog Qu) is the second longest source of the Yangtze River after Dangqu River, with a total length of 361.4 km (224.6 mi) long, located in Qinghai province in the People's Republic of China.

The Ulan Moron begins as melt-off from the Geladandong glaciers and runs to a confluence with the Dangqu or Dam Chu River, where they form the Tongtian River, which subsequently becomes the Yangtze River. Although the Dangqu has been found to be the longest source of the Yangtze under the usual modern criteria, the Ulan Moron has been traditionally regarded as the main river and source. It belongs to the East China Sea watershed basin.
