Yi people in the context of "Nanman"

China proper, also called Inner China or Han China, are terms used primarily in the Western world in reference to the traditional "core" regions of Chinese civilization centered around the Yellow River and Yangtze River valleys. There is no fixed definition for China proper as many administrative, cultural and territorial shifts have occurred throughout history. One definition refers to the original heartland regions of the Chinese civilization, the Central Plain (southern North China Plain around the lower Yellow River valley) as well as the historical Nine Provinces; another to the Eighteen Provinces inside Shanhai Pass designated by the Qing regime. In contrast, Outer China is a term usually includes the peripheral marchland regions such as Gobi Desert,, Tarim Basin, Northeast China, Dzungaria, Tibetan Plateau and Yungui Plateau, which were historically autonomous regions with unstable allegiance to the authority of Chinese monarchs.

The term was first used by the Europeans during the 17th century to distinguish the historical "Han lands" (Chinese: 漢地, i.e. regions long dominated by the majority Han Chinese population) from "frontier" regions of China where Han populations intermix with other indigenous ethnicities (e.g. Turkic peoples such as Uyghurs, Kazakhs and Uzbeks, Mongolic peoples, and Tibeto-Burmese peoples such as Tibetans, Yi and Bai) and newer foreign immigrants (e.g. Slavic colonists such as Russians and Ukrainian Cossacks), sometimes known as "Outer China". There was no direct translation for "China proper" in the Chinese language at the time due to differences in terminology used by the Qing regime to refer to the regions.

The Han Chinese are the largest ethnic group in Mainland China. In 2010, 91.51% of the population were classified as Han Chinese (~1.2 billion). Besides the Han Chinese majority, 55 other ethnic (minority) groups are categorized in present-day China, numbering approximately 105 million people (8%), mostly concentrated in the bordering northwest, north, northeast, south and southwest but with some in central interior areas.

The major ethnic minorities in China are the Zhuang (19.6 million), Hui (11.4 million), Uyghurs (11 million), Miao (11 million), Manchus (10.4 million), Yi (9.8 million), Tujia (9.6 million), Tibetans (7 million), Mongols (6.3 million), Buyei (3.5 million), Dong (3.5 million), Yao (3.3 million), Bai (2 million), Koreans (1.7 million), Hani (1.7 million), Li (1.6 million), Kazakhs (1.5 million), and Dai (1.2 million). In addition, there are a number of unrecognized ethnic groups which together comprise over 730,000 people. Collectively, the ethnic groups of China are referred to as the Zhonghua minzu (Chinese: 中华民族; pinyin: Zhōnghuá mínzú; lit. 'Chinese ethnicity'). However, being part of the Zhonghua minzu (i.e. being part of one of the 56 ethnic groups) does not necessarily mean one must have Chinese nationality (Chinese: 中国国籍; pinyin: Zhōngguó guójí) or be loyal to the People's Republic of China.

Sichuanese, also called Sichuanese Mandarin, is a branch of Southwestern Mandarin spoken mainly in Sichuan and Chongqing, which was part of Sichuan Province from 1954 until 1997, and the adjacent regions of their neighboring provinces, such as Hubei, Guizhou, Yunnan, Hunan and Shaanxi. Although "Sichuanese" is often synonymous with the Chengdu-Chongqing dialect, there is still a great amount of diversity among the Sichuanese dialects, some of which are mutually unintelligible with each other. In addition, because Sichuanese is the lingua franca in Sichuan, Chongqing and part of Tibet, it is also used by many Tibetan, Yi, Qiang and other ethnic minority groups as a second language.

Sichuanese is more similar to Standard Chinese than southeastern Chinese varieties but is still quite divergent in phonology, vocabulary, and even grammar. The Minjiang dialect is especially difficult for speakers of other Mandarin dialects to understand. Sichuanese can be further divided into a number of dialects: Chengdu–Chongqing, Minjiang, Renshou–Fushun, and Ya'an–Shimian. The dialect of Chengdu, the capital of Sichuan province and an important central city, is the most representative dialect of Southwestern Mandarin and is used widely in Sichuan opera and other art forms of the region.

A saddle is a supportive structure for a rider of an animal, fastened to an animal's back by a girth. The most common type is equestrian. However, specialized saddles have been created for oxen, camels and other animals. The trade of making saddles is saddlery.

It is not known precisely when riders first began to use some sort of padding or protection, but a blanket attached by some form of surcingle or girth was probably the first "saddle", followed later by more elaborate padded designs. The solid saddle tree was a later invention, and though early stirrup designs predated the invention of the solid tree, the paired stirrup, which attached to the tree, was the last element of the saddle to reach the basic form that is still used today. Present-day saddles come in a wide variety of styles, each designed for a specific equestrianism discipline, and require careful fit to both the rider and the horse. Proper saddle care can extend the useful life of a saddle, often for decades. The saddle was a crucial step in the increased use of domesticated animals, during the Classical Era.

Lisu (Fraser alphabet: ꓡꓲ-ꓢꓴ, ꓡꓲ‐ꓢꓴ ꓥꓳꓽ or ꓡꓲꓢꓴ; Latin: Lisu ngot; Lisu syllabary: ; Chinese: 傈僳语; pinyin: Lìsùyǔ; Burmese: လီဆူဘာသာစကား, pronounced [lìsʰù bàðà zəɡá]) is a tonal Tibeto-Burman language spoken in Yunnan (Southwestern China), Northern Burma (Myanmar) and Thailand and a small part of India. Along with Lipo, it is one of two languages of the Lisu people. Lisu has many dialects that originate from the country in which they live. Hua Lisu, Pai Lisu and Lu Shi Lisu dialects are spoken in China. Although they are mutually intelligible, some have many more loan words from other languages than others.

The Lisu language is closely related to the Lahu and Akha languages and is also related to Burmese, Jingphaw and Yi languages.

The She–An Rebellion (Chinese: 奢安之亂), also called the Yongning Rebellion, was a Yi uprising that occurred in Sichuan and Guizhou in late fall of 1621. As a consequence of the taxes imposed by the Ming dynasty, the Yi chieftains She Chongming and An Bangyan rose up in revolt. The rebellion lasted almost eight years and was eventually suppressed in the summer of 1629.
