Yi people
The Yi or Nuosu people (historically known as Lolo), are an ethnic group in China, Vietnam and Thailand. Numbering nine million people, they are the seventh largest of the 55 ethnic minority groups officially recognized by the People's Republic of China. They live primarily in rural areas of Sichuan, Yunnan, Guizhou and Guangxi, usually in mountainous regions. Liangshan Yi Autonomous Prefecture is home to the largest population of Yi people within mainland China, with two million Yi people in the region. For other countries, as of 1999, there were 3,300 Mantsi-speaking Lô Lô people living in  the Hà Giang, Cao Bằng and Lào Cai provinces in Northern Vietnam. The Yi speak various Loloish languages, closely related to Burmese. The prestige variety is Nuosu, which is written in the Yi script. Location. Of the more than 9 million Yi people, over 4.5 million live in Yunnan Province, 2.5 million live in southern Sichuan Province and 1 million live in the northwest corner of Guizhou Province. Nearly all the Yi live in mountainous areas, often carving out their existence on the sides of steep mountain slopes far from the cities of China. The altitudinal differences of the Yi  areas directly affect the climate and precipitation of these areas. These striking differences are the basis of the old saying that "The weather is different a few miles away" in the Yi area. Yi populations in different areas are very different from one another, making their living in completely different ways. Subgroups. Although different groups of Yi refer to themselves in different ways (including Nisu, Sani, Axi, Lolo, Acheh) and sometimes speak mutually unintelligible languages, they have been grouped into a single ethnicity by the Chinese and the various local appellations can be classified into three groups: History. According to  Yi legend, all life originated in water and water was created by snowmelt, which as it dripped down, created a creature called the Ni. The Ni gave birth to all life. Ni is another name for the Yi people. It is sometimes translated as black because black is a revered color in Yi culture. Yi tradition tells us that their common ancestor was named Apu Dumu or ("Axpu Ddutmu" or "Axpu Jjutmu"). Apu Dumu had three wives, each of whom had two sons. The six sons migrated to the area that is now Zhaotong and spread out in the four  directions, creating the Wu, Zha, Nuo, Heng, Bu, and Mo clans. The Yi practiced a lineage system where younger brothers were treated as slaves by their elders, which resulted in a culture of migration where younger brothers constantly left their villages to create their own domains. Guizhou kingdoms. The Heng clan divided into two branches. One branch, known as the Wumeng settled along the western slope of the Wumeng Mountain range, extending their control as far west as modern day Zhaotong. The other branch, known as the Chele, moved along the eastern slope of the Wumeng Mountain range and settled  to the north of the Chishui River. By the Tang dynasty (618-907), the Chele occupied the area from Xuyong in Sichuan to Bijie in Guizhou. The Bu clan fragmented into four branches. The Bole branch settled in Anshun, the Wusa branch settled in Weining, the Azouchi branch settled in Zhanyi, and the Gukuge branch settled in northeast Yunnan. The Mo clan, descended from Mujiji (), split into three branches. One branch known as the Awangren, led by Wualou, settled in southwest Guizhou and formed the Ziqi Kingdom. Wuake led the second branch, the Ayuxi, to settle near Ma'an Mountain south  of Huize. Wuana led the third branch to settle in Hezhang. In the 3rd century AD, Wuana's branch split into the Mangbu branch in Zhenxiong, led by Tuomangbu, and Luodian () in Luogen, led by Tuoazhe. By 300, Luodian covered over much of the Shuixi region. Its ruler, Mowang (), moved the capital to Mugebaizhage (modern Dafang), where he renamed his realm the Mu'ege kingdom, otherwise known as the Chiefdom of Shuixi. After the Han dynasty, the Shu of the Three Kingdoms conducted several wars against the ancestors of Yi under the lead of Zhuge Liang. They defeated the king of  Yi, ("Mot Hop", ) and expanded their conquered territory in Yi area. After that, the Jin Dynasty succeeded Shu as the suzerain of Yi area but with weak control. Yunnan kingdoms. Some historians believe that the majority of the kingdom of Nanzhao were of the Bai people, but that the elite spoke a variant of Nuosu (also called "Yi"), a Tibeto-Burman language closely related to Burmese. The Cuanman people came to power in Yunnan during Zhuge Liang's Southern Campaign in 225. By the fourth century they had gained control of the region, but they rebelled against the Sui dynasty  in 593 and were destroyed by a retaliatory expedition in 602. The Cuan split into two groups known as the Black and White Mywa. The White Mywa (Baiman) tribes, who are considered the predecessors of the Bai people, settled on the fertile land of western Yunnan around the alpine fault lake Erhai. The Black Mywa (Wuman), considered to be predecessors of the Yi people, settled in the mountainous regions of eastern Yunnan. These tribes were called Mengshe (蒙舍), Mengxi (蒙嶲), Langqiong (浪穹), Tengtan (邆賧), Shilang (施浪), and Yuexi (越析). Each tribe was known as a "zhao". In academia, the ethnic  composition of the Nanzhao kingdom's population has been debated for a century. Chinese scholars tend to favour the theory that the rulers came from the aforementioned Bai or Yi groups, while some non-Chinese scholars subscribed to the theory that the Tai ethnic group was a major component, that later moved south into modern-day Thailand and Laos. In 649, the chieftain of the Mengshe tribe, Xinuluo (細奴邏), founded the Great Meng (大蒙) and took the title of Qijia Wang (奇嘉王; "Outstanding King"). He acknowledged Tang suzerainty. In 652, Xinuluo absorbed the White Mywa realm of Zhang Lejinqiu, who  ruled Erhai Lake and Cang Mountain. This event occurred peacefully as Zhang made way for Xinuluo of his own accord. The agreement was consecrated under an iron pillar in Dali. Thereafter the Black and White Mywa acted as warriors and ministers respectively. In 704 the Tibetan Empire made the White Mywa tribes into vassals or tributaries. In the year 737 AD, with the support of the Tang dynasty, the great-grandson of Xinuluo, Piluoge (皮羅閣), united the six "zhao"s in succession, establishing a new kingdom called Nanzhao (Mandarin, "Southern Zhao"). The capital was established in 738 at Taihe, (the site  of modern-day Taihe village, a few miles south of Dali). Located in the heart of the Erhai valley, the site was ideal: it could be easily defended against attack and it was in the midst of rich farmland. Under the reign of Piluoge, the White Mywa were removed from eastern Yunnan and resettled in the west. The Black and White Mywa were separated to create a more solidified caste system of ministers and warriors. Nanzhao existed for 165 years until A.D. 902. After 35 years of tangled warfare, Duan Siping () of the Bai birth founded the Kingdom of Dali , succeeding the territory of Nanzhao. Most Yi of that time were under the ruling of Dali. Dali's sovereign reign lasted for 316 years until it was conquered by Kublai Khan. During the era of Dali, Yi people lived in the territory of Dali but had little communication with the royalty of Dali. Kublai Khan included Dali in his domain, grouping it with Tibet. The Yuan emperors remained firmly in control of the Yi people and the area they inhabited as part of Kublai Khan's Yunnan Xingsheng () at current Yunnan, Guizhou and part of Sichuan. In order to enhance  its sovereign over the area, the Yuan dynasty set up a dominion for Yi, Luoluo Xuanweisi (), the name of which means local appeasement government for Lolos. Although technically under the rule of the Yuan emperor, the Yi still had autonomy during the Yuan dynasty. The gulf between aristocrats and the common people increased during this time. Ming and Qing dynasties. Beginning with the Ming dynasty, the Chinese empire expedited its cultural assimilation policy in Southwestern China, spreading the policy of "gaitu guiliu" (, 'replacing "tusi" (local chieftains) with "normal" officials'). The governing power of many Yi feudal lords had previously been  expropriated by the successors of officials assigned by the central government. With the progress of "gaitu guiliu", the Yi area was dismembered into many communities both large and small, and it was difficult for the communities to communicate with each other as there were often Han-ruled areas between them. The Kangxi Emperor of the Qing dynasty defeated Wu Sangui and took over the land of Yunnan and established a provincial government there. When Ortai became the Viceroy of Yunnan and Guizhou during the era of Yongzheng Emperor, the policy of "gaitu guiliu" and cultural assimilation against Yi were strengthened . Under these policies, Yi who lived near Kunming were forced to abandon their convention of traditional cremation and adopt burial, a policy which triggered rebellions among the Yi. The Qing dynasty suppressed these rebellions. After the Second Opium War (1856–1860), many Christian missionaries from France and Great Britain visited the area in which the Yi lived. Although some missionaries believed that Yi of some areas such as Liangshan were not under the ruling of Qing dynasty and should be independent, most aristocrats insisted that Yi was a part of China despite their resentment against Qing rule. Modern era. Long Yun , a Yi, was the military governor of Yunnan, during the Republic of China rule on mainland China. The Fourth Front Army of the CCP encountered the Yi people during the Long March and many Yi joined the communist forces. After the establishment of the PRC, several Yi autonomous administrative districts of prefecture or county level were set up in Sichuan, Yunnan and Guizhou. With the development of automotive traffic and telecommunications, the communications among different Yi areas have been increasing sharply. Yi people face systematic discrimination and abuse as migrant laborers in contemporary China. Language. The Chinese government recognizes six  mutually unintelligible Yi languages, from various branches of the Loloish family: Northern Yi is the largest with some two million speakers and is the basis of the literary language. It is an analytic language. There are also ethnically Yi languages of Vietnam which use the Yi script, such as Mantsi. Many Yi in Yunnan, Guizhou and Guangxi know Standard Chinese and code-switching between Yi and Chinese is common. Script. The Yi script was originally logosyllabic like Chinese and dates to at least the 13th century, but seems to be completely independent of any other known script. Until the early  20th century, usage of this script was primarily the domain of "bimo" priests for transmitting ritual texts from generation to generation. It was not until the mid-twentieth century that elite families in Liangshan began to use the script for non-religious purposes, such as letter writing. There were perhaps 10,000 characters, many of which were regional, since the script had never been standardized across the Yi peoples. A number of works of history, literature and medicine, as well as genealogies of the ruling families, written in the Old Yi script are still in use and there are Old Yi  stone tablets and steles in the area. An attempt to romanize the script was made in the 1950s but it failed to gain traction. In the 1970s and 1980s, the traditional script was standardized into a syllabary. Syllabic Yi is widely used in books, newspapers, street signs, and education, although with increasing influence from Chinese. Culture. Gender. Descent and inheritance in Yi society was traditionally patrilineal and men were generally considered superior to women. In certain locales, Yi women still lag behind men in terms of primary education and very few Yi women become educational instructors or political leaders. Yi  women noticeably drank and smoked more than Han Chinese women. Slavery. Traditional Yi society was divided into four castes, the aristocratic "nuohuo" Black Yi, the commoner "qunuo" White Yi, the "ajia", and the "xiaxi". The Black Yi made up around 7 per cent of the population while the White Yi made up 50 per cent of the population. The two castes did not intermarry and the Black Yi were always considered of higher status than the White Yi, even if the White Yi was wealthier or owned more slaves. The White and Black Yi also lived in separate villages. The  Black Yi did not farm, which was traditionally done by White Yi and slaves. Black Yi were responsible only for administration and military activities. The White Yi were not technically slaves but lived as indentured servants to the Black Yi. The Ajia made up 33 per cent of the population. They were owned by both the Black and White Yi and worked as indentured laborers lower than the White Yi. The Xiaxi were the lowest caste. They were slaves who lived with their owners' livestock and had no rights. They could be beaten, sold, and killed for sport. Membership of  all four castes was through patrilineal descent. The prevalence of the slave culture was so great that sometimes children were named after how many slaves they owned. For example: Lurbbu (many slaves), Lurda (strong slaves), Lurshy (commander of slaves), Lurnji (origin of slaves), Lurpo (slave lord), Lurha, (hundred slaves), Jjinu (lots of slaves). Cases of the caste slavery system's influence could be found as late as the 1980s and early 1990s, when "nuohuo" clans prevented marriage with "qunuo" or punished members who did. Folklore. The most famous hero in Yi mythology is Zhyge Alu. He was the son of  a dragon and an eagle who possessed supernatural strength, anti-magic, and anti-ghost powers. He rode a nine-winged flying horse called "long heavenly wings." He also had the help of a magical peacock and python. The magical peacock was called Shuotnyie Voplie and could deafen the ears of those who heard its cry, but if invited into one's house, would consume evil and expel leprosy. The python, called Bbahxa Ayuosse, was defeated by Zhyge Alu, who wrestled with it in the ocean after transforming into a dragon. It was said to be able to detect leprosy, cure  tuberculosis, and eradicate epidemics. Like the Chinese mythological archer, Hou Yi, Zhyge Alu shoots down the suns to save the people. In the Yi religion Bimoism, Zhyge Alu aids the bimo priests in curing leprosy and fighting ghosts. Jiegujienuo was a ghost that caused dizziness, slowness in action, dementia and anxiety. The ghost was blamed for ailments and exorcism rituals were conducted to combat the ghost. The bimo erected small sticks considered to be sacred, the kiemobbur, at the ritual site in preparation. Torch Festival. The Torch Festival is one of the Yi people's main holidays. According to Yi  legend, there were once two men of great strength, Sireabi and Atilaba. Sireabi lived in heaven while Atilaba on earth. When Sireabi heard of Atilaba's strength, he challenged Atilaba to a wrestling match. After suffering two defeats, Sireabi was killed in a bout, which greatly angered the bodhisattavas, who sent a plague of locusts to punish the earth. On the 24th day of the 6th month of the lunar calendar, Atilaba cut down many pine trees and used them as torches to kill the locusts, protecting the crops from destruction. The Torch Festival is thus held in his honor . Music. The Yi play a number of traditional musical instruments, including large plucked and bowed string instruments, as well as wind instruments called "bawu" (巴乌) and "mabu" (马布). The Yi also play the hulu sheng, though unlike other minority groups in Yunnan, the Yi do not play the hulu sheng for courtship or love songs (aiqing). The kouxian, a small four-pronged instrument similar to the Jew's harp, is another commonly found instrument among the Liangshan Yi. Kouxian songs are most often improvised and are supposed to reflect the mood of the player or the surrounding environment. Kouxian songs  can also occasionally function in the aiqing form. Yi dance is perhaps the most commonly recognized form of musical performance, as it is often performed during publicly sponsored holidays and/or festival events. Literature. Artist Colette Fu, great-granddaughter of Long Yun has spent time from 1996 till present photographing the Yi community in Yunnan Province. Her series of pop-up books, titled "We are Tiger Dragon People", includes images of many Yi groups. Religion. Other religions. In Yunnan, some of the Yi have adopted Buddhism as a result of exchanges with other predominantly Buddhist ethnic groups present in Yunnan, such  as the Dai and the Tibetans. The most important god of Yi Buddhism is Mahākāla, a wrathful deity found in Vajrayana and Tibetan Buddhism. In the 20th century, many Yi people in China converted to Christianity, after the arrival of Gladstone Porteous in 1904 and, later, medical missionaries such as Alfred James Broomhall, Janet Broomhall, Ruth Dix and Joan Wales of the China Inland Mission. According to missionary organization OMF International, the exact number of Yi Christians is not known. In 1991 it was reported that there were as many as 1,500,000 Yi Christians in Yunnan Province, especially in Luquan  County where there are more than 20 churches. Medicine. The Yi are known for the extent of their inter-generational transmission of traditional medicine through oral tradition and written records. Their traditional medicine system has been academically inventoried. Since the prefecture the Yi medicinal data was collected from also contains the cave containing human-infectable SARS clades and it is known that people living in the vicinity SARS caves show serological signs of past infection, it has been suggested that the Yi were repeatably exposed to coronavirus over their history, passively learned to medicinally fend off coronavirus infection centuries ago , and committed the results into their inter-generational record of medicinal indications.
