Datang Chang'an... In 618 AD, Li Yuan proclaimed himself emperor, established the Tang Dynasty, changed Daxing to Chang'an, and further built and improved it after that.

The circumference of Tang Chang'an City is 35.56 kilometers long, with an area of about 87.27 square kilometers, which is 9.7 times the area within the city wall of Xi'an today, 2.4 times the Chang'an City of the Western Han Dynasty, 1.7 times that of the Yuan Dadu, 1.4 times that of Beijing City in the Ming and Qing Dynasties, 7 times that of Constantinople built in 447 AD, 62 times that of Baghdad built in 800 AD, and 7 times that of ancient Rome.

By the Tang Dynasty, Chang'an was the largest and most prosperous international city at that time.

Chang'an City is magnificent in scale, rigorous in layout, symmetrical in structure, and neatly arranged. There are three gates on each side of the outer city, and the six main streets that run through the twelve gates are the main traffic arteries of the city.

The Suzaku Avenue that runs through the north and south is a standard central axis, which connects the Chengtianmen of the palace city, the Suzaku Gate of the imperial city and the Mingde Gate of the outer city, and divides Chang'an City into two parts of east-west symmetry, the east is Wannian County, the west is Chang'an County, and the east and west have a commercial area each, called the East City and the West City. There are 11 main streets in the north and south, and 14 main streets in the east and west, dividing the residential area into 110 squares, which are shaped like a Go board.

In addition to residents, royal families, dignitaries, soldiers, slaves and miscellaneous servants, Buddhist monks and nuns, and ethnic minorities, the total number of foreign merchants, envoys, foreign students, and overseas monks was no less than 30,000.

At that time, as many as 300 countries and regions came to Chang'an and Tang Tong. Tang's science and technology culture, political system, and food fashion spread from Chang'an to the rest of the world. In addition, Western culture was digested and recreated through Tang Chang'an City, and then spread to neighboring countries and regions such as Japan, Korea, and Myanmar. Tang Chang'an became the gathering place of commercial and cultural exchanges between the West and the East in the world, and was the largest international metropolis in the world at that time.

.........................

The next morning, a carriage with the logo of Lu Guogong's Mansion stopped at the door of Li Zhan's house.

Li Zhan explained to his family, and then rode up, Li Qian, Zhang Gong, Li Sheng and others on the side... looked at Li Zhan with envy, without him, they also wanted to take the carriage to Chang'an for a while.

It's just that if it were normal, Li Zhan would bring them with him, but today Li Zhan is going to the Qinglou, so he can't bring these little guys.

The carriage moved forward slowly, and it took more than an hour to reach the front of the Chang'an city wall, and after arriving in Chang'an, Li Zhan stopped the carriage for a while, looking at the majestic city wall, Li Zhan was full of feelings.

You must know that Li Zhan has also seen the old city wall of Chang'an in modern times, but compared with the present, it does not have a sense of majesty and strength.

Li Zhan waved his hand, and the carriage entered Chang'an directly, and the soldiers guarding the city gate on both sides saw that it was the carriage of the Duke of Lu's mansion, and immediately gave way to enter.

The carriage took Li Zhan slowly into the mysterious and ancient capital of Chang'an, at this moment Li Zhan really felt an unprecedented Tang Dynasty, the style here is not a noble concubine swinging, not a splendid city, not the bullshit Tang in "The Legend of the Demon Cat", but an open, tolerant, and confident world cultural center, and also the world's power center.

The neighborhoods and buildings of Chang'an City are thick and elegant, and the people of Chang'an City are proud and gentle.

Tang people's self-confidence, tolerance and kindness, a small owner of a shaving shop, when he said that he was from Chang'an, his eyes were shining; A poet who was locked up in prison talked about the Tang Dynasty with a heroic posture as if he was talking about his home.

This Datang is strong, open, and prosperous, but it is not a dream, but it is very real.

Walking on the street of Chang'an, the street is not too clean, the ancient streets, it is impossible to be spotless with bluestone paving everywhere, you know, ancient Paris is a pile of and urine, even if we are advanced and have a developed drainage system, it is impossible to be a clean metropolis like in the usual film and television dramas.

Chang'an City, a world metropolis with a population of one million, where all countries come to the dynasty and all ethnic groups live together, it should be that every corner has the smell of fireworks, the smell of people, and the smell of earth. When two people fight and a group of people fight, it is impossible not to have mud on their bodies and a little blood and feces on their faces.

Chang'an City is not only a magnificent and magnificent palace, not only a splendid aristocratic woman, a generous and heroic poet and knight, but also a slum in the dark quagmire of sentient beings, this Tang Dynasty is not only a stage for heroic heroes, poets and celebrities to scold Fang Xuan, but also a miserable world for the grass people to survive.

"This is the real Tang Chang'an...!" Li Zhan looked around with a faint smile.

Through the window on the carriage, Li Zhan carefully looked at everything outside, and after a while, the carriage stopped, and then Li Zhan heard Cheng Chumo's voice outside: "Brother Zhan, you are finally here." ”

Opening the carriage, Li Zhan saw Cheng Chumo standing in front of the carriage with a flattering smile, and a group of people followed behind Cheng Chumo.

"Hurry up and call Brother Zhan...!"

Cheng Chumo was obviously the head of this group of people, and after he said a word, the others immediately shouted in unison: "Brother Zhan." ”

"Well... Good...! Li Zhan jumped out of the carriage and came to Cheng Chumo's side and said with a smile: "Brother Cheng, these brothers are...?" ”

"Ahh Cheng Chu smiled and began to introduce his friends to Li Zhan.

The first is Cheng Chumo's younger brother Cheng Chuliang, this guy is very blessed, and he has paid off Li Shimin's daughter Qinghe Princess Li Jing with his meritorious son, and the next one is Cheng Chubi, the official to the right Jinwu general, and one of Cheng Chumo's doglegs, who listens to his eldest brother the most and listens to Cheng Chumo for everything.

There is another person below who is heroic, this one is called Qin Huaiyu, who is Qin Qiong's son.

He was followed by two brothers, Yu Chi Baolin and Yu Chi Baoqing of the Yu Chi family.

The last one is a man in a wheelchair, his eyes are a little gray, a little forced to smile, this is the only son of Langya County Bull Jinda Niu Qi after Cheng Chumo's introduction.

"Are you the son of General Niu?" Li Zhan looked at Niu Qian in a wheelchair with some surprise.

Why Li Zhan is interested in Niu Qian, it is because Li Zhan is very respectful of Niu Jinda, there are many famous generals in the Tang Dynasty, but there should only be Niu Jinda among the incorruptible famous generals.

Niu Jinda has a rough and savage appearance, a black face and hairy hair, and often shows a fierce face, and is often ridiculed by others as the ugliest general.

But he is kind and upright by nature, and in the process of assisting Li Shimin, he did his best and contributed a lot to Li Shimin. After Li Shimin ascended the throne, Niu Jinda was named a general, but Niu Jinda still maintained a hard and simple style of life, and he was quite low-key, and he didn't even fit the aura of a general at all. At home, apart from his wife and a son with a broken leg, there was only one old woman who helped them with household affairs, which was not superior to the ordinary people's life in terms of social conditions at that time.

You tell me, there is no name that will have such hardship as Niu Jinda, almost nothing, which is why Li Zhan admires Niu Jinda very much.
