What counties and districts are included in Longzhong area of Gansu Province?

Longxi is "in the middle of Longxi" and "on Longshang", and Gansu's abbreviation "Long" comes from the historical and cultural area of Longxi. Now there is only one county in this historical region, and Longxi will soon disappear in Gansu. Only the high-powered electric locomotive in Longxi Locomotive Depot, with a small trunk, has traveled between Lanzhou and Tianshui every day for 5 1 year. At the same time, it is silently telling countless people who transit here about this forgotten 600-mile hot land, its aura in China history and the scorching cultural atmosphere that has been covered so far. Longxi is a regional concept relative to history and culture. For example, Li Bai was recorded in ancient books as a person born in Longxi, and Li Shimin was born in Longxi. If we divide Li Bai and Li Shimin into Qin 'an people or Lintao people, the Longxi Courtyard in Jiangyou, Sichuan and Longxi Hall in Longxi County will be replaced by Qin 'an Courtyard and Lintao Hall. As a result, the title of "Longxitang" in overseas programs of CCTV International Channel had to be cancelled or renamed. At the same time, tens of thousands of overseas Li descendants have to give up the customary title of "Longxi", which will become an international joke. In 266 BC, Zhao Haoqi established Longxi County, and after Qin Shihuang unified the six countries, Longxi County was still established. Until A.D. 1669, it was the largest military and cultural center in the west except Chang 'an, Kyoto. He has been exercising the first-and second-level military power under the central government in Longyou. Longxi County was originally under the jurisdiction of Lanzhou City, Dingxi District, Tianshui City and Longnan District. Later, due to its large jurisdiction, it was separated from them and Tianshui County was established: Jincheng County (now Lanzhou City), Wudu County and Anding County. In the Qing dynasty, the governor of Shaanxi and Gansu was enfeoffed, and then Gansu Province was established. The provincial capital is located in Longxi, and it was moved to Lanzhou in A.D. 1669, and then the economic and cultural center was transferred from Longxi to Lanzhou. From thousands of years of history, there are countless historical and cultural celebrities who have been crowned as Longxi. "It is difficult to count the talents in Longxi who entered the official position in the Tang Dynasty for nearly three hundred years. It can be said that in history, there are only a handful of places like Longxi that directly or indirectly transported many talents to the country. The ancients said:' The treasure of heaven and earth is outstanding', which makes Longxi culture crown China "(see" Longxi Literature and History Draft ") follow the names of large regions in history, which is conducive to the continuity of cultural inheritance and the unity of people's understanding of important historical figures. Longxi carries the history and culture of Gansu, which is recorded in historical materials (see the relevant items in the book Twenty-five History for the history of Longxi, and there is a detailed textual research in the Draft of Longxi Literature and History).

Longxi County before Qin and Han Dynasties included Lanzhou, Tianshui and Longnan.
