What's the name of Ping An Jing in Japan now?
Ping An Jing, which means "the capital of peace and stability", was built by Emperor Kanmu following the example of Chang 'an and Luoyang in Sui and Tang Dynasties. The buildings are arranged in a rectangle, with Suzaku Road as the axis, running through the north and south, divided into east and west Beijing, with a palace in the middle.
Outside the imperial city, it is the capital city. The streets in the city are chessboard-shaped, with east-west, north-south direction and uniform layout. Palace, government, residential area and commercial area are clearly defined. The shrine is located in the north, and the streets intersect at right angles.
Ping An Beijing is about 5.2 kilometers long from north to south, 4.5 kilometers long from east to west and covers an area of 23.4 square kilometers, which is equivalent to one fifth of Chang 'an, the capital of China in the Tang Dynasty. As the capital, Ping An Beijing has lasted for nearly a thousand years.
