In fact, Chang’an has never changed its name, because Chang’an has always been a county-level administrative district. In the Han Dynasty, Chang’an County was established. After the central government directly under the central government, it set up “Jingzhao Yin” to govern Chang’an County, and during the Tang Kaiyuan period, it was changed to “Jingzhao House”. In the Yuan Dynasty, the “Jing Zhao Fu” was changed to “Fengyuan Road”.
In the early Ming Dynasty, it was changed to “Xi’an”, the name of Xi’an was born, and Xi’an Prefecture governed Chang’an County and Xianning County.
In the early years of the Republic of China, the county was abolished, and all the states, prefectures, and halls were abolished. Xi’an was abolished, and Xi’an was set up in Shaanxi Province.
After liberation, it became the provincial capital, and it was under the jurisdiction of the former Chang’an County. In 2002, the county of Chang’an County was renamed Chang’an District, so Chang’an has always been there, but it has become the name of a district.
