Ding'an Town

Prior to the Han Dynasty, this region belonged to the Gouding tribe. During the reign of Emperor Wu of Han, the King of Gouding submitted to the Han Dynasty, and the area was incorporated into Zangke Commandery. From the Three Kingdoms period through the Western Jin Dynasty, it was part of Xinggu Commandery's Jouting County. From the Eastern Jin Dynasty to the Southern Liang Dynasty, it belonged to Xiping Commandery. During the Northern Zhou Dynasty and early Tang Dynasty, it was part of Nanning Prefecture (present-day Yunnan). The Tang and Song Dynasties implemented the system of tributary states, while the Yuan and Ming Dynasties enforced the Tusi system. During the Tang Dynasty, it was a tributary state under the jurisdiction of the Qianzhou Military Governorate. In the Song Dynasty and Yuan Dynasty, it belonged to Shanglin Dong. In the seventh year of the Yongle reign of the Ming Dynasty, it was under the Shanglin Chieftain's Office. During the Wanli reign of the Ming Dynasty, it was merged into Sicheng Prefecture. ^[1]

In the fifth year of the Kangxi reign (1666) of the Qing Dynasty, the Reform of the Tusi System was implemented. Xilin County was established on the territory of the former Shanglin Chieftain's Office, with its seat at Zhejiao Village (present-day Ding'an Market). Xilin County was the highest-level administrative division with its seat within the present-day territory of Ding'an Town. In the 28th year of the Guangxu reign (1902), Qing military commander Fang Fugong returned to his hometown. Finding the local name "Zhejiao" (meaning "frog-filled ditch" in Zhuang languages) unsuitable, he consulted local gentry to rename it. He composed a poem on the spot, from which the gentry extracted "Ding'an" as the new place name. Thus, Zhejiao in Xilin County was renamed Ding'an. In 1908, the Central District of Xilin County was established (with its seat at Ding'an Market). In the 22nd year of the Republic of China (1933), Ding'an Township was established within Xilin County.

In March 1950, the Xilin County People's Government was established, with Ding'an Township belonging to the First District. In August 1951, the Guangxi Provincial People's Government abolished Xilin County. The four large townships including Ding'an from the former Xilin County were merged into Tianxi County (later renamed Tianlin County), with Ding'an's territory becoming part of Tianlin County's Seventh District (administered from Ding'an). In 1958, the Xingfu People's Commune of Tianlin County was established (renamed Ding'an Commune in 1961). In 1984, it was reorganized into Ding'an Town.

The town's terrain is predominantly mountainous, classified as a hilly region. Elevations peak in the north, decline in the south, and feature a lower-lying river valley corridor running east-west through the central area. There are 24 peaks exceeding 1,000 meters in elevation, with major summits including Guolipo, Pomoshan, and Guanshan. The highest peak within the township is Guolipo, located north of Balai Village in the northeastern part of Ding'an Town, reaching 1,252.3 meters above sea level.^[1]

Major rivers include the Tuoniang River and the Qingshui River (Namen River). The Tuoniang River is the largest tributary of the Yu River, flowing eastward from Xilin County through four villages—Naxiong, Baxin, Ding'an, and Weimi—in Ding'an Town before exiting Tianlin County via townships such as Badu, Bagui, and Liulong. The Qingshui River enters Ding'an Town from the north, passing through Yangrong, Nameng, and Ding'an villages before joining the Tuoniang River east of Ding'an Market.

Ding'an Town lies within a Humid subtropical climate zone at low latitudes, characterized by strong solar radiation, abundant heat, long summers, short winters, warm temperatures, and moderate rainfall. The annual average temperature is 21°C, with average annual precipitation of approximately 1,280 mm. Primary meteorological hazards include floods and early-season disasters.
