The word "Kun" is the language of "Yi language", that is, the "Kun" family; In ancient China, people on the mainland recorded it in Chinese characters according to the local pronunciation and wrote it as "Kun" or "Kun" or "Kun Mi".
In BC 109 (the second year of Han Yuanfeng), the Western Han Dynasty established Yizhou County in present-day Yunnan Province. There are 24 counties under the jurisdiction of the county, including a famous "Chang County", which is located in the urban area of Kunming today.
In A.D. 1276 (13th year of Yuan Dynasty), the Yuan government changed the Qianhu office in Kunming to Kunming County, which was under the jurisdiction of Zhongqing Road. The organizations of Zhongqing Road and Hangzhongshu Province in Yunnan both live in Kunming County. Since then, Kunming County has become the capital of Yunnan, the political, economic and cultural center of the whole province, and its prosperity is described in the famous book "Travel Notes of Marco Polo" in the 4th century A.D./KLOC-0.
In this travel book, Kunming County is called "Duck Chicheng". In the Ming Dynasty, Zhongqing Road was changed to Yunnan Province, and Kunming County was one of its subordinate counties. Kunming county is not only the capital of Yunnan, but also the capital. This situation remained unchanged throughout the Qing Dynasty.
Extended data:
"Kunming" was originally the name of an ancient nation in southwest China.
The "Kunming State" in China's ancient books refers to the area around Erhai Lake in Dali. Because there are a large number of Kunming ethnic groups here, with concentrated residence and closed geographical location, it is by no means a country established by Kunming ethnic groups in southwest China.
Like other ancient ethnic groups in China, Kunming ethnic groups have formed some new ethnic groups after thousands of years of integration and differentiation. Sui and Tang Dynasties were divided into Wuman, Baiman, Hehan, Mohan, Dong and Luluman. Its various names are too numerous to mention. After the Song and Yuan Dynasties, it gradually divided into Yi, Bai, Naxi, Hani, Lisu and Lahu ethnic groups.
Generally speaking, the word "Kunming" is the name of an ancient nation living in the southwest of China, not the name of a city, not the meaning of "big city" in ancient Thai. This ancient nation is the ancestor of the Yi, Bai, Naxi, Hani and Lisu nationalities in the southwest of China today.
No matter from the basic vocabulary or customs, Kunming people are not the ancestors of Thailand, Shaanxi, China and Zhuang. Tangte Lozanashan (Chen) thinks that Kunren is "another branch of the Thai nation" in the history of the ancestral struggle of the Thai nation, which is far from the objective historical facts.
