Yunnan topics

Yunnan , () is a landlocked province in the southwest of the People's Republic of China. The province spans approximately and has a population of 48.3 million (as of 2018). The capital of the province is Kunming. The province borders the Chinese provinces of Guizhou, Sichuan, autonomous regions of Guangxi, and Tibet as well as Southeast Asian countries: Vietnam, Laos, and Myanmar. Yunnan is China's fourth least developed province based on disposable income per capita in 2014.

Yunnan is situated in a mountainous area, with high elevations in the northwest and low elevations in the southeast. Most of the population lives in the eastern part of the province. In the west, the altitude can vary from the mountain peaks to river valleys by as much as . Yunnan is rich in natural resources and has the largest diversity of plant life in China. Of the approximately 30,000 species of higher plants in China, Yunnan has perhaps 17,000 or more. Yunnan's reserves of aluminium, lead, zinc and tin are the largest in China, and there are also major reserves of copper and nickel.

The Han dynasty first recorded diplomatic relations with the province at the end of the 2nd century BC and the province became part of the Silk Road to Bhitargarh in Bangladesh. The area was ruled over by the Sino-Tibetan-speaking kingdom of Nanzhao (738–937), followed by the Bai-ruled Dali Kingdom (937–1253). After the Mongol invasion of the region in the 13th century, Yunnan was conquered by the Ming dynasty.

From the Yuan dynasty onward, the area was part of a central-government sponsored population movement towards the southwestern frontier, with two major waves of migrants arriving from Han-majority areas in northern and southeast China. As with other parts of China's southwest, Japanese occupation in the north during World War II forced another migration of Han people into the region. These two waves of migration contributed to Yunnan being one of the most ethnically diverse provinces of China, with ethnic minorities accounting for about 34 percent of its total population. Major ethnic groups include Yi, Bai, Hani, Zhuang, Dai, and Miao. Yunnan has also been identified as "the birthplace of tea ... the first area where humans figured out that eating tea leaves or brewing a cup could be pleasant", and as the region of origin of the genus ''Cannabis'' plant.

Etymology

The name "Yunnan" first referred to a place when the Han dynasty created Yunnan County near modern Xiangyun. During the Tang dynasty, Emperor Xuanzong gave Piluoge, the chief of Nanzhao, the title of "King of Yunnan", because Nanzhao originated from Yunnan county. Gradually the king of Yunnan controlled more and more territory, and "Yunnan" became the common name of this area. Therefore, the Yuan dynasty created the Yunnan Province after it occupied the Dali Kingdom.

Han dynasty literature did not record the etymology of "Yunnan", and there are many theories about its origin. One common theory states that the name means "south of colorful clouds" (). Some annals in the Ming dynasty, for example ''Dian Lüe'' () and ''Yunnan General Annals'' (), support this. However, modern historian Tan Qixiang states that this theory is a superficial explanation of the literal meaning. Another common theory is that the name means "south of Yun Range" () However, this has been disproven because the name "Yunling Mountains" first appeared in Tang dynasty (618–907) literature, but the name "Yunnan" first appeared during the Han dynasty (202 BC – 220 AD). Modern research gives more conjectures. You Zhong said "Yunnan" means "south of the mountain (referring to the Cang Mountain) with clouds". Wu Guangfan said "Yunnan" might be a Loloish or Bai name.

History

Prehistory

The Yuanmou Man, a '' Homo erectus'' fossil unearthed by railway engineers in the 1960s, has been determined to be the oldest-known hominid fossil in China. By the Neolithic period, there were human settlements in the area of Lake Dian. These people used stone tools and constructed simple wooden structures.

Dian Kingdom

Around the 3rd century BC, the central area of Yunnan around present day Kunming was known as Dian. The Chu general () entered the region from the upper Yangtze River and set himself up as "King of Dian". He and his followers brought into Yunnan an influx of Chinese influence, the start of a long history of migration and cultural expansion.

Han conquest

In 221 BC, Qin Shi Huang unified China and extended his authority south. Commanderies and counties were established in Yunnan. An existing road in Sichuan – the "Five Foot Way" – was extended south to around present day Qujing, in eastern Yunnan. In 109 BC, the Han dynasty invaded Dian during its southern expeditions. Under orders from Emperor Wu, General () was sent south to Yunnan, eventually establishing the Yizhou commandery. By this time, agricultural technology in Yunnan had improved markedly. The local people used bronze tools, plows and kept a variety of livestock, including cattle, horses, sheep, goats, pigs and dogs. Anthropologists have determined that these people were related to the people now known as the Tai. They lived in tribal congregations, sometimes led by exiled Chinese.

During the Three Kingdoms, the territory of present-day Yunnan, western Guizhou and southern Sichuan was collectively called Nanzhong. The dissolution of Chinese central authority led to increased autonomy for Yunnan and more power for the local tribal structures. In AD 225, the famed statesman Zhuge Liang led three columns into Yunnan to pacify the tribes. His seven captures of Meng Huo, a local magnate, is mythologized in the Romance of the Three Kingdoms.

Cuan Kingdom

In the 4th century, northern China was largely overrun by nomadic tribes from the north. In the 320s, the Cuan () clan migrated into Yunnan. Cuan Chen () named himself king and held authority from Lake Dian, then known as Kunchuan. Henceforth the Cuan clan ruled eastern Yunnan for over four hundred years.

International trade flowed through Yunnan. An ancient overland pre-Tang trade route from Yunnan Province passed through Irrawaddy in Burma to reach Bengal. Yunnan was inhabited by so-called barbarians not fully under the control of the Tang government and the route, though ancient, was not used much in pre-Tang times, and Chinese attempts to control the route were disrupted by the rise of Nanzhao.

Nanzhao period

Yunnan was settled by several local tribes, clans, and cultures before the 8th century. Around Lake Erhai, namely, the Dali area, there emerged six zhao: Mengzi (), Yuexi (), Langqiong (), Dengdan (), Shilling (), and Mengshe (). Zhao () was an indigenous non-Chinese language term meaning "king" or "kingdom." Among the six regimes Mengshe was located south of the other five; therefore given the new, larger context, it was called Nanzhao (Southern Kingdom).

By the 730s Nanzhao had succeeded in bringing the Erhai Lake–area under its authority. In 738, the western Yunnan was united by Piluoge, the fourth king of Nanzhao, who was confirmed by the imperial court of the Tang dynasty as king of Yunnan. Ruling from Dali, the thirteen kings of Nanzhao ruled over more than two centuries and played a vital role in the dynamic relationship between the Tang dynasty and the Tibetan Empire as a buffer state.

By the 750s, Nanzhao had conquered Yunnan and became a potential rival to Tang China. The following period saw several conflicts between Tang China and Nanzhao. In 750, Nanzhao attacked and captured Yaozhou, the largest Tang settlement in Yunnan. In 751, Xianyu Zhongtong (), the regional commander of Jiannan (present-day Sichuan), led a Tang campaign against Nanzhao. The king of Nanzhao, Geluofeng, regarded the previous incident as a personal affair and wrote to Xianyu to seek peace. However, Xianyu Zhongtong detained the Nanzhao envoys and turned down the appeal. Confronted with Tang armies, Nanzhao immediately turned its allegiance to the Tibetan Empire. The Tubo and Nanzhao agreed to be "fraternal states"; Geluofeng was given the titles zanpuzhong ("younger brother"). The Nanzhao-Tubo alliance ensured a disastrous defeat for Xianyu's expedition, with the Tang general's army of 80,000 men being reduced to a quarter of its original size.

Tang China did not give up after one failure. In 753, another expedition was prepared, but this was also defeated by Nanzhao. In 754, the Tang organized an army of more than 100,000 troops that advanced to the Dali plain, resulting in only another slaughter. By the end of the eighth century, Tang was no longer a major threat to Nanzhao.

Nanzhao's expansion lasted for several decades. In 829, Nanzhao suddenly plundered Sichuan and entered Chengdu. When it retreated, hundreds of Sichuan people, including skilled artisans, were taken to Yunnan. In 832, the Nanzhao army captured the capital of the Pyu kingdom in modern upper Burma. Nanzhao also attacked the Khmer peoples of Zhenla. Generally speaking, Nanzhao was then the most powerful kingdom in mainland Southeast Asia, and played an extremely active role in multistate interactions.
In 859, Nanzhao captured Bozhou, and this event exacerbated the Nanzhao-Tang clashes. When the Tang governor of Annam took Bozhou back in the following year, Nanzhao, with the help of native peoples, occupied Hanoi as the Tang army moved to Bozhou. When the Tang forces returned, Nanzhao troops retreated from Hanoi but attacked and plundered Yongzhou. In the winter of 862, Nanzhao, allying with local groups, led an army of over 50,000 men to invade Annam again. It is reported that the Tang forces lost over 150,000 soldiers (either killed or captured by
Nanzhao) in the two Annam battles. The autumn of 866 saw Tang victory in Hanoi and soon all of the Nanzhao forces were driven away. But Tang China had lost its ability to attack Nanzhao.

While Nanzhao was being defeated in Annam, it still occasionally attacked Sichuan. In 869, Shilong (), the eighth king and the first empire of Nanzhao, invaded Sichuan. In 874, Nanzhao attacked Sichuan again.

In 902, Zheng Maisi, the ''Qingpingguan'' (,"Prime Minister") of Nanzhao, murdered the infant king of Nanzhao, and established a new kingdom called Dachanghe. Nanzhao, a once-powerful empire, disappeared. In 928, Yang Ganzhen (楊干貞) usurped the Dachanghe king and established Zhao Shanzheng, a qingpingguan as emperor of Datianxing (大天興). In 929, Yang Qianzhen abolished Zhao Shanzheng and established himself as Emperor of Dayining (大義寧).

Dali Kingdom

In 937, Duan Siping overthrew the Dayining Kingdom and established the Dali Kingdom. The kingdom was conquered by the Mongol Empire in 1253 after Dali King Duan Xingzhi defected to the Mongols. The Duans incorporated into the Mongol dominion as Maharajas of the new province. The Mongolian prince sent to administer the region with them was killed. In 1273, Kublai Khan reformed the province and appointed the semu Ajall Shams al-Din Omar as its governor. The Yunnan Province during the Yuan dynasty included significant portions of Upper Burma after the First Mongol invasion of Burma in the 1270s and 1280s. With the fall of the Yuan dynasty in 1368, the Ming dynasty destroyed the Yuan loyalists led by Basalawarmi and the remnants of the House of Duan in the Ming conquest of Yunnan by the early 1380s.

Ming and Qing dynasties

The Ming installed Mu Ying and his family as hereditary aristocrats in Yunnan.

During the Ming and Qing dynasties, large areas of Yunnan were administered under the native chieftain system. Under the Qing dynasty a war with Burma also occurred in the 1760s due to the attempted consolidation of borderlands under local chiefs by both China and Burma.

Yunnan was a destination for Han Chinese during Yuan rule. Colonizers moved into the area during Ming and Qing rule. During the Ming dynasty, 3 million Han Chinese mostly from Nanjing (the original Nanjing population was later largely replaced by Wu-speakers), and some from Shanxi and Hebei, settled in Yunnan.

Although largely forgotten, the bloody Panthay Rebellion of the Muslim Hui people and other local minorities against the Manchu rulers of the Qing dynasty caused the deaths of up to a million people in Yunnan.Gernet,
Jacques. ''A History of Chinese Civilization''. 2. New York: Cambridge
University Press, 1996. The Manchu official Shuxing'a started an anti-Muslim massacre, which led to the rebellion. Shuxing'a developed a deep hatred of Muslims after an incident in which he was stripped naked and nearly lynched by a mob of Muslims. He ordered several Muslim rebels to be slowly sliced to death. Tariq Ali wrote about the real incident in one of his novels and claimed the Muslims who had nearly lynched Shuxing'a were not Hui but belonged to another ethnicity. Nevertheless, the Manchu official blamed all Muslims for the incident. A British officer testified that the Muslims did not rebel for religious reasons and that the Chinese were tolerant of different religions and were unlikely to have caused the revolt by interfering with the practice of Islam. Loyalist Muslim forces helped Qing forces crush the rebel Muslims. The Qing armies massacred only Muslims who had rebelled or supported the rebels and spared Muslims who took no part in the uprising.

In 1894, George Ernest Morrison, an Australian correspondent for ''The Times'', traveled from Beijing to British-occupied Burma via Yunnan. His book, ''An Australian in China'', details his experiences.

The 1905 Tibetan Rebellion in which Tibetan Buddhist Lamas attacked and killed French Catholic missionaries spread to Yunnan.

Post-Imperial

Yunnan was transformed by the events of the Second Sino-Japanese War, which caused many east coast refugees and industrial establishments to relocate to the province. It assumed strategic significance, particularly as the Burma Road from Lashio, in Burma to Kunming was a fought over supply line of vital importance to China's war effort.

University faculty and students in the east had originally decamped to Changsha, capital of Hunan. But as Japanese forces were gaining more territory they eventually bombed Changsha in February 1938. The 800 faculty and students who were left had to flee and made the 1,000 mile journey to Kunming, capital of Yunnan in China's mountainous southwest. It was here that the National Southwest Associated University (commonly known as Lianda University) was established. For eight years, staff, professors and students had to survive and operate in makeshift quarters that were subject to sporadic bombing campaigns by the Japanese. There were dire shortages of food, equipment, books, clothing and other essential needs, but they managed to conduct the running of a modern university. Over those eight years of war (1937–1945), Lianda became famous nationwide for having and producing many, if not most, of China's most prominent academics, scholars, scientists and intellectuals. Both of China's only Nobel laureates in physics studied at Lianda in Kunming.

Naturalists

Thousands of plant, insect and mammal species were described in the 19th century by scientists of the French National Museum of Natural History, Paris, in connection with permanent settlements of missionaries of the in north-west Yunnan, among them noticeably Jean-André Soulié and Felix Biet. From 1916 to 1917, Roy Chapman Andrews and Yvette Borup Andrews led the Asiatic Zoological Expedition of the American Museum of Natural History through much of western and southern Yunnan, as well as other provinces of China. The book, '' Camps and Trails in China'', records their experiences. Other notable explorers include Heinrich Handel-Mazzetti; George Forrest; Joseph Francis Charles Rock, who from 1922 to 1949 spent most of his time studying the flora, peoples and languages of southwest China, mainly in Yunnan; and Peter Goullart, a White Russian who studied Naxi culture and lived in Lijiang from 1940 to 1949.

Geography

Yunnan is the most southwestern province in China, with the Tropic of Cancer running through its southern part. The province has an area of , 4.1% of the nation's total. The northern part of the province forms part of the Yunnan–Guizhou Plateau. The province borders Guangxi and Guizhou in the east, Sichuan in the north, and the Tibet Autonomous Region in the northwest. It shares a border of with Myanmar ( Kachin and Shan States) in the west, Laos (Luang Namtha, Oudomxay, and Phongsaly Provinces) in the south and Vietnam (Hà Giang, Lào Cai, Lai Châu, and Điện Biên Provinces) in the southeast.
For practical purposes, all of Yunnan province falls within the Zomia region of Asia.

Geology

Yunnan is at the far eastern edge of the Himalayan uplift, and was pushed up in the Pleistocene, primarily in the Middle Pleistocene, although the uplift continues into the present. The eastern part of the province is a limestone plateau with karst topography and unnavigable rivers flowing through deep mountain gorges. The main surface formations of the plateau are the Lower Permian Maokou Formation, characterized by thick limestone deposits, the Lower Permian Qixia Formation, characterised by dolomitic limestones and dolomites, the Upper Permian basalts of the Ermeishan Formation (formerly Omeishan plateau basalts), and the red sandstones, mudstones, siltstones, and conglomerates of the Mesozoic– Paleogene, including the Lufeng Formation and the Lunan Group (Lumeiyi, Xiaotun, and Caijiacong formations). In this area is the noted Stone Forest or Shilin, eroded vertical pinnacles of limestone (Maokou Formation). In the eastern part the rivers generally run eastwards. The western half is characterized by mountain ranges and rivers running north and south.

Paleontology

*Yunnanozoon – Lower Cambrian possible chordate
* Jingshanosaurus – Early Jurassic long-neck prosauropod dinosaur

Climate

Yunnan has a generally mild climate with pleasant and fair weather because of the province's location on south-facing mountain slopes, receiving the influence of both the Pacific and Indian oceans, and although the growing period is long, the rugged terrain provides little arable land. See '' Agriculture in Yunnan''. Under the Köppen climate classification, much of the province lies within the subtropical highland (Köppen ''Cwb'') or humid subtropical zone (''Cwa''), with mild to warm winters, and temperate summers, except in the almost tropical to truly tropical south, where temperatures regularly exceed in the warmer half of the year. ''In general'', January average temperatures range from ; July averages vary from . Average annual rainfall ranges from , with over half the rain occurring between June and August. The plateau region has moderate temperatures. The western canyon region is hot at the valley bottoms, but there are freezing winds at the mountaintops.

Topography

The terrain is largely mountainous, especially in the north and west. A series of high mountain chains spreads across the province. There is a distinct canyon region to the west and a plateau region to the east. Yunnan's major rivers flow through the deep valleys between the mountains.

The average elevation is . The mountains are highest in the north where they reach more than ; in the south they rise no higher than . The highest point in the north is the Kawagebo Peak in Deqin County on the Diqing Plateau, which is about ; and the lowest is in the Red River Valley in Hekou County, near the Vietnamese border, with an elevation of .

The eastern half of the province is a limestone plateau with karst scenery and unnavigable rivers flowing through deep mountain gorges; the western half is characterised by mountain ranges and rivers running north and south. These include the Nu Jiang (Salween), the Lancang (Mekong), and the Jinsha (Yangtze), which flow in close proximity in the Three Parallel Rivers protected area. The rugged, vertical terrain produces a wide range of flora and fauna, and the province has been called a natural zoological and botanical garden.

Borders

Bordering Chinese provincial-level divisions are Tibet, Sichuan, Guizhou and Guangxi. Starting from the east and working clockwise, bordering countries are Vietnam (Hà Giang, Lào Cai, Lai Châu and Điện Biên provinces), Laos (Phongsaly, Oudomxay and Luang Namtha provinces), Myanmar (states of Shan and Kachin). The main border crossings are:

* Hekou–Lào Cai, by road and rail, is the only Sino-Vietnamese land border crossing open to non-Chinese/non-Vietnamese.
*Sino-Laotian at Boten
*Ruili–Muse is the only Sino-Burmese border crossing open to non-Chinese/non-Burmese.

Lakes

There are several major lakes in Yunnan. The province has nine lakes with areas of over . They include:

* Dianchi Lake, near Kunming
*Fuxian Lake, in Yuxi, the second deepest lake in China
* Xingyun Lake, directly south of Fuxian Lake and connected with it by a short river
*Qilu Lake, south of Fuxian and Xingyun Lakes, separated from them by mountains, in Tonghai County
*Erhai Lake, near Dali City
*Lugu Lake, in Ninglang near the border with Sichuan
*Yangzong Lake, in Yiliang County
*Yilong Lake

Rivers

Yunnan is the source of two rivers, the Xi River (there known as the Nanpan and Hongshui) and the Yuan River. The Hongshui is a principal source stream of the Xi River. Rising as the Nanpan in eastern Yunnan province, it flows south and east to form part of the boundary between Guizhou province and Guangxi autonomous region. Flowing for , it unites with the Yu River at Guiping to form what eventually becomes the Xi River.

The province is drained by six major river systems:
*the Yangtze River, here known as the Jinsha Jiang (River of Golden Sands), drains the province's north.
*the Pearl River, with its source near Qujing, collects the waters from the east.
*the Mekong (Lancang), which flows from Tibet into the South China Sea forming the boundaries between Laos and Burma, between Laos and Thailand and through Laos, Cambodia and Vietnam
*the Red River (Yuan or Honghe) has its source in the mountains south of Dali and enters the South China Sea through Hanoi, Vietnam
*the Salween (Nujiang), which flows into the Gulf of Martaban and the Andaman Sea through Burma
*the Irrawaddy, which arises from the confluence of two rivers in Kachin State in Burma, has a few small tributaries in Yunnan's far west, such as the Dulongjiang and Taping River, and rivers in the prefecture of Dehong.

Biodiversity

Yunnan is China's most diverse province, biologically as well as culturally. The province contains snow-capped mountains and true tropical environments, thus supporting an unusually full spectrum of species and vegetation types. The Yunnan camellia (''Camellia reticulata
