There are a total of 160 Lu li in the city of Chang'an in the Han Dynasty, "the living rooms are lined up, and the doors and alleys are straight". The most famous ones are Xuanming, Jianyang, Changyin, Shangguan, Xiucheng, Huangjiao, Beihuan, Nanping, Dachang, Qili, etc., when Emperor Xuan of Han was in the people, he lived in Shangguanli. In addition, there are Wuli, Qianli, Nanli, Xuanli, Jiaoyangli, Lilili, Lianglingli, Danglili, Xiaoli, Anyangli, etc., which are also found in the literature or "Juyan Hanjian". Chen Zhi believes that the Lingli in the literature is the provincial name of Lianglingli, and Xuanli and Jianli are also the provincial names of Xuanming and Huangjiaoli respectively. In the second year of the first year of the Yuan Dynasty (2 A.D.), "another five miles were raised in the city of Chang'an, and the house was 200 districts to live in the poor." If it is five miles, it is about forty districts per mile. Because the southern half of the city is basically occupied by the palace, the general residents can only live in the northern half of the city or near the city gate, and only a few powerful people can live near the north of Weiyang Palace, so there is the title of "North Que Jiadi". There are many powerful people living near Xuanping Gate, which is called "Xuanping Guili". Because the northern half of the city is mainly inhabited, there are many trading markets in between.

It is said that there are nine cities in Chang'an City in the Han Dynasty, with 260 steps on all sides. The nine cities are mainly set up with Hengqiao Avenue, "six cities are in the west of the province, and three cities are in the east of the province", "to the people of Kyushu in the Tumen (i.e., Hengmen)", "the city buildings are all heavy houses", indicating that there are many shops and prosperous business, which has the basic characteristics of ancient Chinese cities where people come and go and are bustling. In order to manage market transactions, "to inspect the business and property of the trade", "the market building has an ordinance". The names of the cities recorded today include eight cities: Liushi, Dongshi, Xishi, Zhishi, Jiaomen, Xiaoli, Jiaodaoting, and Gaoshi. There are also names of four cities in the literature, apparently referring to the four cities. It is generally believed that the nine cities of Chang'an in the Han Dynasty refer to the eastern, western, southern, and northern cities, as well as Liushi, Zhishi, Xiaoli, Jiaomen, and Jiaodaoting cities. Among them, Xiaoli City is in the east of Yongmen. Jiaodaoting City is in the east of the bridge, and Zhishi and Jiaomen City are in the north of Weiqiao. It proves that the markets of Han Chang'an were mainly distributed in the northwest of the city and near Hengqiao. This is because after the Silk Road was opened up as a communication road to the Western Regions, merchants from the Western Regions first crossed the Wei River from the Bianqiao or Zhongwei Bridge (i.e., Hengqiao) into the northwest of Chang'an City. Since the northwest part of Chang'an City has become a place where merchants gather, it has become natural for commerce to flourish. In addition, the east-west avenue that crosses the Guanzhong Plain also crosses the Wei River from the cross-bridge and the temporary bridge, and there are many trading markets near the cross-bridge and the temporary bridge, and the business is developed, which is also the inevitable result of the convenient transportation. The market of Chang'an City in the Han Dynasty was prosperous, and many millionaires appeared, among which Wanzhang of Dongshi and Liushi (Xicheng) were representatives. In the fourth year of the first year of the Yuan Dynasty (4 A.D.), "it is also the gate of Fangshi." Zhou Huan is lined up, merchants live in it, and all merchants are outside it", which proves that since the Han Dynasty, merchants have settled in the market, creating a new situation in China's urban commercial trade.

The palace building is the core of the capital, and the palace of Chang'an City in the Han Dynasty occupies almost half of the Chang'an City. If it is divided according to the area where the palace is located, it can be roughly divided into Weiyang Palace District, Changle Palace District and Jianzhang Palace District, which are all a huge building group. It not only occupies a vast area, but also has a high hall and a low space, and the rows are lined up one after another, each with its own characteristics.

Weiyang Palace is located in the southwest of the city. Magnificent. Due to its location in the west, it is also known as the "West Palace". There are 43 halls in Weiyang Palace, and there are 22 miles in circumference. In fact, there are 50 places in the names of the main halls recorded in the records, such as the front hall, the high gate, the Yilan, the Chengming, the Qingliang, the Xuan Room, the greenhouse, the Jinhua, the Yutang, the White Tiger, the Qilin, and the Jiaofang Palace. There are not many names. The scale of Weiyang Palace is large, and the palace is prosperous. It has indeed reached a new peak. It is centered on the front hall (located in the north of Ximazhai Village in the northwest suburb of present-day Xi'an) and spreads out in all directions. The layout of the palace is coordinated and generous, neat and beautiful. The front hall is located at the highest point of the whole palace, and its base site is about 350 meters long from north to south, about 200 meters wide from east to west, and about 15 meters from the highest point in the north. About 200 meters on the north side of the ruins of the front hall of Weiyang Palace, the ruins of a large hall are located in a large hall, covering an area of 40 acres, cleaning up the foundation site of the house and paving tiles, steps, wells, etc., as well as other relics, winding corridors and loops, there are many buildings, it is said that it may be the Jiaofang Hall where the queen lives in the Weiyang Palace. In addition to the palace, there are many platforms, pavilions, que, rooms, etc. The collection of the world's secretaries includes Tianlu Pavilion (now the north of Xiaoliuzhai Village), Shiqu Pavilion (now the northwest of Kejiazhai) and Qilin Pavilion; In charge of the secretary of the book, the imperial historian lived in Lantai, the emperor and his ministers ascended to look out at Bailiangtai, and there was a gradual platform in the pond; There is a weaving room for making beautiful silk fabrics for the court, a storm room for exposing to the fabric and dyeing materials, and a Ling room for collecting ice cubes. According to exploration, the whole palace is a regular square, there are walls on all sides, the circumference is nearly 9 kilometers, 21 miles in the Han Dynasty, the area is about 5 square kilometers, accounting for one-seventh of the total area of Chang'an City. Weiyang Palace is a typical representative of palace architecture in the early Han Dynasty, with a grand scale and a long duration, which has a profound impact on the palace architecture of that time and later generations.

Changle Palace is located in the southeast of Chang'an City in the Han Dynasty, it is repaired on the basis of Qin Xingle Palace, because of its location in the east, it is called "East Palace". At the beginning of the Han Dynasty, Liu Bang once "looked at the court" here, and later it was the place where the empress dowager lived. Xingle and Changle are named after their auspicious names. Changle Palace is more than 20 miles around, and there are 14 main halls. In fact, there are 17 palace names in the record, such as the front hall, Xuande, Gaoming, Tongguang, Changqiu, Yongshou, Yongning, greenhouse, and pepper room. The detection results prove that the shape of Changle Palace is an irregular rectangle, with a circumference of 10 kilometers, more than 20 miles in the Han Dynasty, and an area of about 6 square kilometers, accounting for one-sixth of the total area of Chang'an City.

Jianzhang Palace was built during the time of Emperor Wu of the Han Dynasty, located in Jianzhang Township in the west of Chang'an City, and the palace was named after the township. It is said that due to the fire in the Bailiang Terrace of Weiyang Palace, the big house was revived to win it, "so it was built as a chapter palace, and the degree was thousands of households." Jianzhang Palace was built outside the city because Weiyang Palace "built a wide area", and there was really no place in the city. Therefore, in the west of the city, it is determined by the topographical characteristics of the suburbs and the water supply situation. Jianzhang Palace is more than 20 miles around, the scale is grand, and there is a flying pavilion across the city wall to connect with Weiyang Palace. It is composed of 26 palaces such as Xiaodang, Yusa, Fangyi, Tianliang, Qibao, Drum Spring, etc., 26 halls such as Yutang, Shenmingtang, Shupu, Mingluan, Qihua, Tongzhu, Hande, Taiye Pond, Tangzhong Pond, Fengque, Shenmingtai and so on. In addition to the palace building, there is Taiye Pond in the northwest of the front hall, there are Jade Hall, Bimen, and the genus of the big bird in the south, there are Shangzhong (Shang Ting) and Tiger Circle in the west, and there are Fengque in the east, etc., which complement each other with the palace, and it is very spectacular. The Taiye Pond is 10 acres around, the blue waves are rippling, and there is "Penglai, Abbot, Yingzhou, Huliang, like the genus of the turtle and fish of the sacred mountain in the sea", it is the resort of the emperor's amusement. In the northwest of the pond, there is also a 50-zhang high god platform, Jingganlou, which is the place where the emperor worships the gods.

The palace buildings of Chang'an City in the Han Dynasty, in addition to the above three palaces, also have the North Palace, the Gui Palace and the Mingguang Palace (the northeast corner of the city), etc., all of which are gold and jade households, and are magnificent. These palaces mainly occupy the southern half of the city, because the south of the Han Chang'an city is leaning on the Longshou Plain, and the southern part of the city is higher.

The layout of Chang'an City in the Han Dynasty is in line with the Zhou Li. The basic principle of the "Examination of the Gongji", that is, the south is the palace area, and the north is the market, residents, and handicraft area, which is very neat. It should be said that for the first time, it completely embodied the principles of urban layout stipulated in the "Zhou Li", created a new regulation for the overall layout of China's capital, and set a model for the planning and design of the capital city in the future. This is to make full use of the geographical advantages, plan out areas with different functions, so that various terrain characteristics can play a role. In particular, the wide opening of water sources and the digging of a complete network of water supply canals have opened up a new situation for the water supply of China's capital.

Chang'an is a city with a unique charm, as the imperial capital that has existed for many years, there are things that other cities can not match, from the inside to the outside are full of a king's atmosphere, the building here is so magnificent, magnificent, even after the baptism of war is still heavy, the grass and trees here are even more unique, whether it is the imperial palace or the folk architecture here is not lost atmosphere, Guan Yu is in Chang'an City, personally feel the prosperity and vicissitudes of this imperial capital, can not help but sigh with emotion.

This is the second capital he has won, Chang'an City used to be a place that many people yearn for, a place that many people dream of, and when he sets foot on this land, he will still think of some swan songs about this imperial capital: "Lu Zhaolin's "Knot Guest Youth Field" Chang'an Ancient Meaning Lu Zhaolin Chang'an Avenue is even narrow and sloping, and the green ox and white horse are seven incense cars. The jade chariot crossed the main house, and the golden whip flocked to the Hou family. The dragon title covers the sunrise, and the phoenix spits tassels with the sunset. A hundred zhang gossamer competes around the tree, and a group of delicate birds cry flowers. Crying flowers and butterflies on the side of a thousand doors, green trees and silver platforms of ten thousand colors. The double road crosses the window as a acacia, and the double que is connected with the wings of the phoenix. The Liang family painting pavilion rises in the sky, and the Han Emperor's golden stem is straight outside. I don't know each other in front of the building, and I don't know each other. borrowed a to Ziyan, and once learned to dance for a long time. If you have to become a muddle, why die, and be willing to be a mandarin duck and not an immortal. The flounder mandarin duck is really enviable, and the double goes and the double comes to the king. The hated account is embroidered with a lonely luan, so as to take the door curtain and double swallow. Shuangyan flies around the painting beam, and Luo Weicui is tulips. Pieces of clouds are lined with cicada sideburns, and the slender early moon is crow-yellow. The crow yellow powder white car is, and the delicate and delicate attitude is not one. The demon boy BMW is even rich, and the prostitute is on his knees. The dark night cries in the Imperial History Mansion, and the birds in front of the Tingwei Gate want to perch. Faintly Zhucheng Linyu Road, far away Cui Wan no golden embankment. Bomb flying eagle Duling north, Tan Pill borrowed the west of Weiqiao. Invite the chivalrous Furong Sword to stay with the prostitute. The prostitute skirt at dusk, the atmosphere of the song is full of mouth. The north hall is like the moon at night, and the south is like a cloud. Nanmo and Beitang are connected to Beili, and three of the five dramas control three cities. The weak willow and green acacia are hanging on the ground, and the good air is red and the dust rises in the dark sky. In the Han Dynasty, Jin Wuqian rode in, and the jade slaughtered Su parrot cup. Luo Xiangbao belt is the king's solution, and Yan Ge Zhao dance is the king's opening. Don't have a luxury called the general, and the day will not give in. The origin of the spirit is the drain and irrigator, and the dictatorship does not tolerate Xiao Xiang. The authoritarian spirit is heroic, and the green and purple swallows sit in the spring breeze. He said that he had been singing and dancing for thousands of years, and he called himself arrogant and extravagant. The scenery of things does not treat each other, and the mulberry field and blue sea must be changed. In the past, the gold-level white jade hall was now only seen in the green pines. Lonely and lonely Yangzi dwelling, a bed of books every year. The unique Nanshan osmanthus hair, flying around and attacking people. (To be continued......)
