Wikpedia says that Guangxi China became autonomous 50 years ago on Dec 11, 2008. So, 1958 they became an autonomous region.
Thinkquest says that: Self-government in ethnic group autonomous areas is affected through the local people's congress and people's government at the particular level. There are currently five autonomous regions in China. They are Inner Mongolia Autonomous Region founded on May 1, 1947, Ningxia Hui Autonomous Region founded on October 25, 1958, Xinjiang Uygur Autonomous Region founded on October 1, 1955, Guangxi Zhuang Autonomous Region founded on March 5, 1958 and Tibet Autonomous Region founded on September 9, 1965. In addition, China also has 30 autonomous prefectures and 121 autonomous counties (or in some cases, banners). The committee of the People's Congress and the head of the government of an autonomous region, autonomous prefecture or autonomous county belong to the area's designated ethnic group.
Organs of self-government in regional autonomous areas enjoy extensive self-government rights beyond those held by other state organs at the same level. These include enacting regulations for self-government and specialized regulations corresponding to local political, economic and cultural conditions; making independent use of local revenue, and independently arranging and managing construction, education, science, culture, public health and other local undertakings. The Central Government has greatly assisted in the training of ethnic group cadres and technicians through the establishment of institutes and cadre schools for minority ethnic groups to supplement regular colleges and universities. It has, in addition, supplied the ethnic group autonomous areas with large quantities of financial aid and material resources in order to promote their economic and cultural development.http://library.thinkquest.org/05aug/01780/chinese-ethnic-group/index.htm
Our guide in Guangxi said he thought Lil M was part of a "minority" group in China.
(this is also from the thinkquest site) - China is a large country noted for its dense population and vast territory. There are 55 minority ethnic groups in addition to the Han who represent 92% of the population. The defining elements of an ethnic group are language, homeland, and social values. 53 minority ethnic groups use spoken languages of their own; 23 minority ethnic groups have their own written languages.
Most of the 7 percent of the minority ethnic groups live in the vast areas of the West, Southwest (Mia is from Southwest China) and Northwest. The largest is the 12 million-strong Zhuang in southwestern China. Although minority ethnic groups account for about 7% of the population, they are distributed over some 50% of Chinese territory, mostly in the border regions. Equality, unity and common prosperity are the fundamental objectives of the government in handling the relations between minority ethnic groups. China exercises a policy of regional autonomy for various minority ethnic groups, allowing ethnic group peoples living in compact communities to establish self-government and direct their own affairs.Peace
