There are 18 in the palace, 19 in Langzhong Palace, 20 in Guo Xiang Palace, 2 1 in Fengchang Hall, 22 in Danong Hall, 23 in Neiting Hall and 23 in Shaofu Hall, all of which are places where Gong Bei and Fuya were built in the early days of the People's Republic of China, and the rest still maintain the basic pattern of 12 gates and 24 streets in the Eastern Han Dynasty. In 227 AD, Wei built palaces, temples, clubs and yamen on a large scale in Luoyang. Based on Yecheng, he formally abandoned the Nangong and built the North Palace, and moved the central axis of the original city to the west, making its north face the main entrance of Gong Bei. Build official offices on both sides of this avenue. According to the theory of "Zuo Zu You She" in Li Zhoukao Gong Ji, ancestral temples and ancestral houses were built on the east and west sides of the southern section of the avenue, and bronze camels were arranged on the roadside at the north end. Cao Weishi also built three small towns in the northwest corner of Luoyang, connecting the north and the south. They are called Jinyong Town or Luoyang Town, with a length of1080m from north to south and a width of 250m from east to west. The palace is built inside, and there are many buildings in the city. It was a defensive stronghold built under the influence of three stations built in the northwest of Yecheng, and it was the product of the war environment at that time. The residential and commercial areas in Luoyang are still blocked by Lihe City. With the strengthening of Wei and Jin Dynasties, cities and residential areas appeared outside Luoyang. After the Western Jin Dynasty unified the whole country, Luoyang became the capital of the whole country. Its characteristic is that the palace is in the middle of the north, and there is a north-south street in front of the palace, which leads directly to the main entrance of the south of the city. The yamen, ancestral hall and Taishe are built on the street, forming the axis of the whole city, and the rest areas are arranged in Fangshi. Because it was the capital of the unified dynasty after the Eastern Han Dynasty, it was modeled by its successor, the Eastern Jin Dynasty, and the sixteen-country regime that appeared in the north one after another, and the capital was imitated and attached to Luoyang to varying degrees. Luoyang had an important influence on the capital of China before the Sui Dynasty.
When the rulers of the Northern Wei Dynasty restored Luoyang city and palace, they did not make any major changes, but built squares around the city, forming a foreign country with a distance of 20 miles from east to west and a distance of 0/5 from north to south. In the Northern Wei Dynasty, there was a city wall outside Luoyang, which was also divided into closed rectangular squares and cities, forming a grid-like street. The transformation of the inner city in the Northern Wei Dynasty was mainly to straighten the streets and concentrate the main office on the Bronze Camel Street outside the main entrance of Gongnan, so as to strengthen the central axis of the city and highlight the center of gravity of Miyagi in the city. The newly-built Waiguo surpassed Chang 'an and Luoyang in Han Dynasty, both in founder and scale. Luoyang City has disappeared in the Northern Wei Dynasty, but the architectural splendor can be imagined from the building materials unearthed from the site. In addition, from the murals of McKee in Tianshui, Gansu, we can also see the face of the northern city at that time. Jianye, the capital of the Eastern Jin Dynasty, was renamed Jiankang. In order to gain a firm foothold in politics and show that it is the continuation of the orthodox dynasty in the Western Jin Dynasty, the Eastern Jin Dynasty reformed Jiankang in terms of capital construction according to the Wei, Jin and Luoyang models. Moving eastward to Miyagi, it is adjacent to the Imperial Street of Wu Dynasty in the south, and the Imperial Street extends southward, crossing the Suzaku navigation pontoon of Qinhuai River and offering sacrifices to heaven in the southern suburbs, forming the north-south central axis of the city facing the main entrance and main hall of Miyagi. The official offices were built around the Imperial Street, and the ancestral hall and Taishe were built around the Qinhuai River at the southern end. After this reconstruction, the palace in Jiankang City is in the north, with streets in the north and south, government offices in the left and right, and Curie outside the palace. The number of city gates has also increased to 12, following the old name of Luoyang, which basically conforms to the Luoyang model. The population of Jiankang moved to the south was very large, and the local gentry had to open up new residential areas along the outside of Qingxi in the east of the city. Jiankang has the convenience of shipping along the river and various water networks. Zhoushan can reach Jiankang City on the east and west sides through Qinhuai River, and some settlements appear along the river water network. In order to defend Jiankang, a number of military bases in small towns have been built around it; Some overseas Chinese counties were built in order to resettle the scholars who moved south. In 420 AD, Song Wudi established the Song Dynasty in the Eastern Jin Dynasty, known as Liu Song in history. Since then, it has entered the Southern Dynasties, where Qi and Liang flourished and the economy became more prosperous. The urban settlements around Jiankang, such as Shicheng, Dongfu, Xizhou, Yecheng, Yuecheng, Baixia, Xinlin, Danyang County and Nanlangya County, have gradually developed residential areas and commercial areas and gradually become one. In the heyday of the Liang Dynasty, Jiankang has developed into a big city with a population of about two million, starting from Shitou Town in the west, east to Downey, north to Zijin Mountain and south to Yuhuatai. Jiankang did not build a foreign country, but only used fences as the outside world, with 56 fences. It can be seen that it was the largest and most prosperous city in China at that time.
