Chang'an, its city is roughly in modern Xi'an.

As a native of Sichuan, Shaanxi is a province in Lin, and she has been to Xi'an too much.

The difference between Xi'an and other cities is that it wears a beautiful necklace - Xi'an City Wall, also known as Xi'an Ming City Wall, as the name suggests, was built in the Ming Dynasty, in the third year of Hongwu by Ming Taizu Zhu Yuanzhang, the Ming City Wall is still intact and wraps the ancient city of Xi'an, the circumference of the city wall is 13.74 kilometers, and the area of the city is 11.32 square kilometers.

And how big is Chang'an at this time?

The area is 87 square kilometers, if you divide it by 11.32, that is, Chang'an at this time is more than 7 times larger than Ming Xi'an, and more figuratively, it is more than 7 times the area within the city wall of Xi'an.

Speaking of the area, and then the perimeter, its circumference is nearly 36 kilometers, which is slightly longer than the length of the current Beijing Second Ring Road.

Therefore, 87 square kilometers is really a very large number, and if the subway can be built at this time, it is estimated that at least more than 10 stations will be needed.

Especially at the moment when science and technology are extremely low, all the way from Qinghe County, most of the places are wilderness, at first glance I saw such a huge city, even if it is a large and medium-sized city today, Liu Chenxing only opened his mouth all the way after entering the city.

Looking down at the road, it is still an earthy yellow rammed earth road, but this road surface is too wide!

Liu Chenxing estimated that it was at least 150 meters wide, twice as wide as Chang'an Avenue in front of Tiananmen Square in Beijing, and thought about the area of the city, the roads should not be so wide, so he raised his head and said: "Uncle, are we walking on Zhuque Street?" If you follow this road, you should be able to reach the Imperial City, and then Miyagi. ”

Liu Wensu saw Liu Chenxing stepping on the ground in disbelief, thinking that when he first arrived in Chang'an from a small county town, he was not shocked in his heart, so he could only act calmly, and he smiled when he saw this, and was about to introduce it, but Liu Chenxing was still shocked and sighed one moment ago, and he had already guessed it the next moment, which seemed to be far better than his own calm on the surface but turned the river and the sea in his heart.

And so determined......

Liu Wensu's eyes deepened, looking at Liu Chenxing, who had a childish face, he remembered Liu Chenxing's amazing memory when he was a child, and now it seems that it is far more than that.

I don't know how far I've grown over the years?

A thought flashed, and remembered the stack of letter paper received every year, sprinkled with a record of learning and life, unconsciously, the yellowed rice paper on a boxy small block letter, all turned into a pear vortex in front of the smiling girl, as if he had never been absent from the girl's growth in the past eight years.

That's good, but the strangeness of eight years is gone.

Liu Wensu's thoughts changed instantly, he only looked at Liu Chenxing with a smile and introduced: "Yes, the street we are standing on now is Suzaku Street, which is the central axis of Chang'an City, and it is also the widest street in Chang'an City. Walk down Suzaku Street, and when you pass the Suzaku Gate, you will see the Imperial City, and then the Miyagi where the saint is located. ”

“…… Suzaku divided Chang'an City into two parts, east and west, the east of the street is under the jurisdiction of Wannian County, and the west of the street is under the jurisdiction of Chang'an County, that is to say, the entire Chang'an City is composed of two counties of Wannian and Chang'an. ”

In the afternoon of this day, Liu Wensu's gentle and clear voice kept talking slowly.

The brother and sister seem to have returned to their childhood, and Liu Wensu opened the door to study for them, and now they follow Liu Wensu into Chang'an City, the foot of the Son of Heaven.

While following along, I listened to Liu Wensu explain to them.

Many years later, the first impression of recalling the huge Chang'an City will always be the Chang'an in Liu Wensu's mouth that afternoon.

Chang'an City covers an area of 87 square kilometers and is divided into three parts: the palace city, the imperial city and the outer Guo city.

Miyagi, located at the north gate of Chang'an City, is the location of the imperial palace, where the saints went to the early dynasty, reviewed the chapters, and harem.

The Imperial Castle, to the south of Miyagi, is separated from Miyagi by a 440-meter-wide side street. This place is the location of the imperial court office, which is equivalent to what modern people call the government affairs office.

And all the places except the palace city and the imperial city are the outer castles, which are the residences of the common people and officials and the location of the industrial and commercial markets.

As an ordinary person, the imperial city and the palace city naturally cannot enter and exit casually, and the outer Guocheng is the main place where the common people live.

Chang'an's Waiguo City and the prefecture and county cities seen along the way are actually similar in concept, both are composed of Fangfang, but Chang'an's Waiguo City is much larger.

There are 8 north-south streets and 14 east-west streets, dividing the residential areas in Chang'an into 108 squares of comparable size, making the entire Chang'an City present a chessboard-like layout.

These 108 squares are 108 squares, and a wall about 3 meters wide is built around the square, and the doors are generally opened on all sides. Each square is responsible for opening and closing the door of the fang, the left and right street envoys are responsible for public security, and Wuhou shop is set up in the corner of the square, which is the modern street police station.

In short, the setting and management of Guocheng outside Chang'an is almost the same as that of Qingyang County, which Liu Chenxing is familiar with, and Beizhou City, where he has lived for a while.

At this time, Liu Wensu talked about the distribution of the fang, "Since the imperial court is located in the north of Chang'an City, the princes and clans roughly live in the fangs around the imperial city of Miyagi, and most people live in the south of the city. ”

This is easy to understand, modern cities have a rich area and ordinary citizens live in the living area, Liu Chenxing nodded, and then "Fang" asked: "Uncle, I heard that Pingkangfang is a gathering place for people to be raised, selected and officials who go to Beijing to report on work, so is the Fang where we live close to Pingkangfang?" ”

Liu Qingshan was surprised that the person who walked by by mistake was a red-haired foreigner, but as soon as he heard the word "Pingkangfang", his eyes immediately lit up, and he didn't look east and west, just stared at Liu Wensu.

At this time, the brother and sister who hated each other were surprisingly consistent, and their eyes were full of anticipation when they looked at him.

The curvature of Liu Wensu's mouth remained unchanged, but the smile in his eyes faded, and he raised his eyebrows lightly and said: "Indeed, Pingkangfang is the most frequented place for all kinds of people who come to Chang'an, and it is also the largest brothel gathering place in Chang'an. ”

Liu Chenxing had a strong desire to survive, and noticed that Uncle Liu's expression was wrong, so she immediately changed the conversation and said: "Uncle, Ah Xing wants to talk about Liquanfang, I heard that there are many restaurants and restaurants in Liquanfang, and Ah Xing wants to go to Liquanfang the most!" What is Pingkangfang, what kind of place is that, it's very boring! ”

Liu Wensu had seen Liu Chenxing's ability to see the wind and turn the rudder, but he had seen it as early as when he was four or five years old, but he didn't expect that it was still the same as when he was a child, and he was happy in his heart, so he didn't say much about "Pingkangfang", and changed the topic as he wished: "Uncle will rest the day after tomorrow, and then I will take Ah Xing to Liquanfang for a good meal, and I should also wash the dust for your brothers and sisters." ”

Hearing this, Liu Chenxing suddenly breathed a sigh of relief.

Liu Wensu said again: "Okay, the place where my uncle lives has arrived." ”
