The exact location of the ancient capital of Japan, Ping An Jing (Kyoto).

Ping An Beijing is located in the center of Kyoto, and now it is the capital of Kyoto.

Cross the mountains and return to Ge Ye? Aidang County, a rectangular capital, is 4.5 kilometers long from east to west and 5.2 kilometers long from north to south. At the northern end of Ping 'an Beijing, the center is Danili (Imperial City), starting from Danili, which is Suzaku Avenue running through the city center. Suzaku Avenue divides Ping An Beijing into sakyo and Youjing (sakyo in the east and Youjing in the west). Among them, Beijing follows the design of Chang 'an City in Sui and Tang Dynasties, and Zuojing follows the design of Luoyang City. The walls of this city no longer exist. The choice of this land is said to be based on the correspondence of the four geomantic gods in China.
