Zhuanglang River has a long history. As early as the Paleolithic, people lived and multiplied on both sides of the river. It is one of the activity areas of the legendary Fu and Nu Wa. According to legend, Yu Xia divided the world into Kyushu, and Zhuanglang belonged to "the domain of Yongzhou" in Xia and Shang Dynasties. The Western Zhou Dynasty was a nomadic place in Xirong, which was within the scope of "waiting for clothes"; During the Spring and Autumn Period and the Warring States Period, it was still occupied by Xirong. In the middle of the Spring and Autumn Period, it belonged to the territory of Qin State. After Qin Shihuang destroyed the Six Kingdoms, Zhuanglang area has been under the jurisdiction of Longxi County (now Lintao County, Gansu Province), the five counties in Guanzhong of Qin Dynasty. In the 5th year of the Han and Yuan Dynasties (BC 106), Zhuanglang area belonged to Tianshui County, the secretariat of Liangzhou (Longcheng belongs to the state, now Longcheng Town, Qin 'an County). County belongs to Tianshui County (now Qin 'an County, Gansu Province) Lueyang Road. ), Jiequan County (located in Handian Township, southeast of Zhuanglang County, Gansu Province) and Ji Cheng County (located in Zhiping Township, Jingning County, Gansu Province). The northeast of the county belongs to Jingyang County of Anding County (now Jingyuan County of Ningxia Hui Autonomous Region). Wang Mang usurped another water county in the Han Dynasty as "Chongrong County" and once set up a county. Zhuanglang area belongs to the above two counties. 17 (74), Emperor Yongping of the Eastern Han Dynasty changed Tianshui County of Liangzhou secretariat to Hanyang County (now Gangu County, Gansu Province), abandoned Jiequan County and merged into Lueyang County. Zhuanglang belongs to Lueyang County and Ayang County. In the fourth year of Xian Di Chuping (139), Yongyang County was separated from Hanyang County, Lueyang County was changed to Jieting County, and Zhuanglang area belonged to Ayang and Jieting County of Yongyang County (this county is now Handian Township in southeast Zhuanglang County, Gansu Province).
During the Three Kingdoms period, Zhuanglang County was under the jurisdiction of Cao Wei and Zhou Yong. Dixian Jian 'an is 19 (2 14), Yongyang County is Guangwei County (which governs Lin Wei, now southwest of Qingshui County in Gansu Province), and Jieting County is changed to Lueyang County. Zhuanglang belonged to Lueyang County in Guangwei County at that time. During the Taishi period of the Western Jin Dynasty (265-274), Guangwei County was restored to Lueyang County. During the Sixteen Kingdoms Period of the Eastern Jin Dynasty, the "five shells" such as Xiongnu, Bian, Qiang, Xianbei and Jie moved in one after another, with frequent wars and numerous national regimes. Zhuanglang county is all under the state power. During the 200-year period from 3 17 to 589, the minority regimes that generally ruled our country successively included, pre-Qin, post-Qin, Northern Wei, Western Wei, Northern Zhou and other countries. Among them, Zhuanglang of former Zhao belongs to Lueyang County. In the second year of Yongxing in the former Qin Dynasty (385), Emperor Fu Li was named "Pingliang County in Gaoping Town". At this time, a small part of the northern part of Zhuanglang County is under the jurisdiction of Pingliang County, Jingzhou, and most of the northern and southern parts are still under the jurisdiction of Lueyang County, Qin Zhou. In the seventh year of Emperor Andi in the Eastern Jin Dynasty, he begged for help to return to his hometown for three years (465,438+065,438+0). After the Western Qin Dynasty begged for help to return to his hometown, Wang Jing, the magistrate of Nan 'an in Qin Dynasty, was in Shuiluo, which is the earliest record of the existing place names of Zhuanglang in history. The name "Shuiluo" continued in the historical trend 1587. When Emperor Tuoba Tao of the Northern Wei Dynasty was in power, Zhuanglang County belonged to Ayang County, Lueyang County and Qin Zhou in the north and Longcheng County in the south. It belongs to Huating County, Pingliang County, Jingzhou. In the third year of Yong 'an (530), King Xiao Zhuang, one of the leaders of Guanlong Rebel Army, once proclaimed himself emperor in Shuiluo, Lueyang County, and captured by two pillars of skylight. This historical material can be found in the History of the North. Li Daoyuan called Shuiluo Town Shuiluo Pavilion in the Notes on Shuijing. Pavilion was then a local grass-roots organization, equivalent to the current village-level institutions. In 543 AD, the Northern Wei Dynasty was divided into the Eastern Wei Dynasty and the Western Wei Dynasty, which were replaced by the Northern Qi Dynasty and the Northern Zhou Dynasty respectively. Wei Shizhuang Lang is under the jurisdiction of Anyang County in northern Qin Zhou; The Northern Zhou Dynasty changed Beizhouqin to Jiaozhou, and Zhuanglang belonged to Anyang County of Jiaozhou.
