Which country did Yunan County in Guangdong belong to in ancient times?

Yun 'an County belongs to Yunfu City, located in the west of Guangdong Province, on the south bank of the middle reaches of Xijiang River. Nanguang High-speed Railway, Guangkun Expressway and Yunfu-Luoding Expressway pass through the territory.

In 206 BC, Qin died and Han Sheng flourished. Zhao Tuo, the former captain of Nanhai County, took the opportunity to establish Nanyue State in Lingnan, and he also accepted the title of Han Dynasty. In the sixth year of Emperor Ding Yuan (1 1 1), Nanyue State was destroyed and nine counties were established in its territory. One of the counties is Cangwu County, which has 10 counties, and one of the 10 counties is Duan Xi County. Today's Yunan County is a part of Duan Xi County at that time.

During the reign of Taikang in the Western Jin Dynasty (280-289), Duluo County (now the capital of Yunnan) and Wucheng County were added to Duan Xi County.

In the seventh year of Yonghe in the Eastern Jin Dynasty (35 1), Jin Kang County was separated from Cangwu County, and Duan Xi County and today's Yunan and Deqing counties were under the jurisdiction of this county.

At the end of the Eastern Jin Dynasty, Jinhua County was established in Jin Kang County (now Nanjiangkou Town, Yunnan Province).

During the Yuanjia period of the Southern Song Dynasty (424-453), Duluo and Wucheng counties merged, renamed Ducheng County (hence the name of Ducheng), separated from Duan Xi County, and merged into Ansui County (Liantan Town, Yu Ling). During the Southern Qi Dynasty (479-502), Weicheng County was separated from Duan Xi County (the county is now a town in Yunnan).

In the fourth year of the Southern Liang Dynasty (523), Luoyang County was established in Guluoshui (namely Wenchang Water) basin, and now part of Yunan County is included in this county. At the beginning of Sui Dynasty, Luoyang County was changed to Luoyang County.

In the ninth year (589), due to the abolition of Jin Kang County, Ducheng County was placed under Cangwu County.

In the 12th year (592), Jinhua and Weicheng counties were merged into capital counties.

In the 18th year (598), Luoyang County was renamed Zhengyi County.

In the third year of Daye (607), Zhengyi County was merged into Longshui County of Yongxi County. Ansui County was also classified as Yongxi County.

The state-county system was implemented in the Tang Dynasty. Ducheng County was placed under Kangzhou, and Ansui County was placed under Kangzhou from Yongxi County and renamed as Jin Kang County.

In the fifth year of Song Kaibao (972), Ducheng County and Jin Kang County were merged into Duan Xi County, which belonged to Deqing House of Guangnan East Road.

The Yuan Dynasty followed the Song system. Only Deqing House was renamed Deqing Road. Yunan County is also one of the jurisdictions of Deqing Road.

In the Ming Dynasty, Deqing Road was renamed Deqing House, and soon Deqing House was reduced to Deqing State, which belonged to Zhaoqing House.

In the fourth year of Wanli (1576), the Ming government set up Luoding Zhili Prefecture in this area as the Minister of Public Affairs of Guangdong. Zhili Prefecture governs not only Longshui County, but also the newly established Dong 'an County (now Yunfu County) and Xining County (now Yunan County). The following year, Xining County built a town in present-day Yunnan, and began to build a city as a county government, which is the origin of the name of the city.

The Qing Dynasty adopted the organizational system of the Ming Dynasty, but in the 22nd year of Qianlong (1757), part of Xining County was transferred back to the original Xinyi County. In the third year of the Republic of China (19 14), Xining County was renamed Yunan County because it had the same name as Xining City in Qinghai Province, which was located on the south bank of Guyujiang River (now Xijiang River).
