In the Tang Dynasty, Luo Feng, the prince of Nanzhao, left an envoy to Chang 'an to worship the king of Tang Dynasty. The remote guide said: under the clouds in the south. So in the eyes of the imperial court, Yunnan was synonymous with the southwest frontier region of the motherland. In the sixteenth year of Kaiyuan, the Tang King named Ge Luofeng as the king of Yunnan. In the 11th year of Yuan Dynasty, Yunnan and other places were set up as the book provinces, and Yunnan was officially determined as the name of Yunnan.
Yunnan county once had Yunnan County, Yunnan Huang and Yunnan Prefecture, and the word Yunnan has always been used. As early as 19 BC, Emperor Wu of the Han Dynasty established Yunnan County in Yunnan. From the Ming Dynasty to the Qing Dynasty, it was a leisure time for the use of the names of Yunnan counties and provinces, and Yunnan counties were often called Little Yunnan. In the seventh year of the Republic of China, Yunnan County was renamed Xiangyun County to avoid having the same name.
Extended information
Yunnan Province, referred to as Yun for short, is a provincial-level administrative region of the People's Republic of China and the capital of Kunming. Located in the southwest border of China, it is bounded by 21 8 ′-29 15 ′ north latitude and 97 31 ′-16 11 ′ east longitude. It is adjacent to Guizhou and Guangxi in the east, Sichuan in the north, Tibet in the northwest, Myanmar in the west, Laos and Vietnam in the south, with a total area of 394, square kilometers.
In the 14th year of Hongwu in the Ming Dynasty, a general with a strong army entered the border of Yunnan from a place called Kedu, and the wind on the plateau made the flag of the Ming army hunt. This man was Fu Youde, the founding star of the Ming Dynasty. A thousand years later, in the same place where the Ming army stopped to look around, Zhuge Liang, another more famous strategist, also stopped here when he marched back to the DPRK in Qujing, Yunnan.
Because the surging waters of Beipanjiang River cut off the way of the Shu army, "Kedu" became the name of this important traffic station in ancient times. The difference is that Zhuge Liang and his men have gone through all the hardships in the barbarian land, and the triumphant move of troops is in sight. And Fu Youde's army took the first step from here. After entering Yunnan, this famous general in Zhennan was invincible, and the Tusi regime, which was scattered in the wild, succumbed to the wind.
