"Deputy Administrative Center" is not a strange term in China. As early as the Xia Dynasty, it was said that there were three "deputy administrative centers" called the capital-Anyi (now Xiaxian, Shanxi), Pingyang (now Linfen, Shanxi) and Jinyang (now Taiyuan, Shanxi); At the end of Shang Dynasty, Chao Ge became the "deputy administrative center". Although there was no capital at that time, Yin lived and worked here most of the time. Before the demise of the Shang Dynasty in the Western Zhou Dynasty, Fengyi and Gaoyi (both near Xi 'an) separated by a Feng Shui River were designated as capitals, among which Fengyi, the oldest, was the "Deputy Administrative Center". After the demise of the Shang Dynasty, a "Deputy Administrative Center" was established in Luoyi (now Luoyang, Henan Province) in the Central Plains.

According to "History of Zhang Han Liangchuan", Sean thought that Luoyang was "a small country, but hundreds of miles, with a thin land and being attacked on all sides, not a country that used force"; Chang 'an is "Huang Jincheng thousands of miles away, a land of abundance".
