When Zhongjing City was first built, it was designed to accommodate a total population of 20,000, but the population moved in that year was less than 10,000, and the total population of Zhongjing City was about 18,000 in the following years.

When Zhongjing City was built, the specifications of the house were divided into three classes:

The first class is the royal palace, covering an area of nine acres, with dozens of houses, the north is the residential area, and the south is the office area;

The second class is the residence of senior officials, which covers an area of half an acre and one acre, and both have multiple houses, which are suitable for large families of dozens of people;

The third class is a three-room ordinary residential house, suitable for small families with a population of less than 10 people, but when a family has more than 6 people, it can be crowded, and many families will build a lower house in the courtyard to store objects or people.

With the rapid increase in the population of Xia Kingdom, the population of Zhongjing City has also increased, and the first expansion of Zhongjing City began, and the population of Zhongjing City after the expansion has reached 50,000.

However, at that time, Su Yan set the rule that the population of Zhongjing City should not exceed 30,000 people, because the population of Zhongjing City is larger, and the grain produced by the farmland around Zhongjing City cannot meet the needs of the residents of Zhongjing City, so it is necessary to transport a large amount of grain from other places, wasting manpower and material resources, which is not feasible for the Xia Kingdom, which is short of manpower.

In the first expansion, the houses in the capital city were added by one level, ranging from 100 square meters to 300 square meters, and the houses of more than 100 square meters were suitable for families with a larger population.

When large-scale homes were clearly priced, many families began to save up money to live in larger houses.

Because the population of the Xia Kingdom continued to increase, Su Yan also carried out a second expansion of Zhongjing City during his reign, and the Zhongjing City after the completion of the expansion can accommodate a maximum of 200,000 people, and at the same time, after the completion of the expansion, the Zhongjing City no longer has an outer city wall, and even the inner city wall has been demolished, only the courtyard wall of the palace is used as a city wall.

At the time of the second expansion of Zhongjingcheng, the Xia Kingdom was already strong enough, and it did not encounter an opponent who could make the Xia Kingdom take out one-tenth of its strength, and there would be no enemy to hit the Zhongjing City, and there would be no beasts around the Zhongjing City, so it was already unnecessary to build a tall city wall in the city, after all, the construction of the city wall was also a large-scale project.

The current Xia King Long Chi is the fifth Xia King, and also the great-great-grandson of Su Yan, the fourth Xia King carried out the third expansion of Zhongjing City during his reign, which is now Zhongjing City, and the Zhongjing City after the completion of the expansion has very big changes compared with the previous Zhongjing City.

At present, Zhongjing City is still a relatively regular square, with a side length of nine kilometers, covering an area of about 81 square kilometers, which can accommodate a million people.

Zhongjing City is divided into nine districts from north to south and west to east, namely due north, northeast, northwest, east, central, west, south, southeast and northeast.

Each area is a square of nine square kilometers with a side length of three kilometers, and the current Zhongjing City is equivalent to eighty-one Zhongjing cities that have not been expanded, or twenty Zhongjing cities at the time of the first expansion, or nine Zhongjing cities at the time of the second expansion.

The north area is the royal palace, and the previous palace is still divided into two areas, the upper and lower (north and south) two areas, the palace covering an area of nine square kilometers is divided into two parts, the lower palace is the area where the Xia king and the Xia officials deal with political affairs, and the upper palace is the living area of most of the descendants of the Xia family in the middle of the capital, and now many descendants of the Long family will move out of the palace after they become a family.

The Northeast and Northwest Districts are the residential areas of some of the Long's children, middle-level senior officials (including military officers), and wealthy people, all of which are mansions (manors) with a large area, and the smallest mansions will not be less than two acres.

The central area is the center of Zhongjing City, there is a tall bell tower in the middle, and most of the central area is a square, mainly a place where the residents of Zhongjing City gather, and the Xia King will hold many large-scale activities such as military parades here.

The East and West Districts, also known as the East Market and the West Market, are the two most important commercial areas in the city, with a variety of medium-sized large restaurants, restaurants, teahouses, theaters, casinos, etc.

There are casinos, but there is no women's branch, and the casino is not open by anyone, there are all kinds of strict regulations, for the Xia Dynasty, which has been established for more than 170 years, gambling / Bo can not be blocked, small gambling pleasure, big gambling hurts, people who open casinos must dissuade those who want to gamble, and will be punished if they do not dissuade.

The southern, southeastern, and southwestern districts are the main residential areas of the middle and lower class residents, and the southern, southern, and southwestern districts should be separated from the southeastern and southwestern districts.

Zhengnan District is dominated by houses (villas) of 150 square meters to 2 acres, and the highest floors will not exceed three floors, mainly middle-class nationals with a certain amount of wealth, a small number of small wealthy families, most of the middle-level officials and a small number of low-level officials live here.

The southeast and southwest districts are the so-called ordinary people's residential areas, but also building areas, the two areas are dominated by six-storey residential buildings, a suite area ranges from 30 square meters to 150 square meters, the higher the floor, the cheaper the price of the house, after all, there is no elevator, it is very tiring to go upstairs back and forth, so only ordinary people with low income live in buildings.

The southeast and southwest districts are also the most densely populated areas in the city, nearly one million people in the city, 80 percent of the population live in these two districts, dense but not crowded, there are very spacious streets extending in all directions when building, all kinds of civil facilities are complete, the dense population does not make the southeast and southwest districts dirty and messy, and the diligent "road sweepers" keep these two areas relatively clean.

On the surface, people with different status live in different areas, but the vast majority of residents in Zhongjing City do not have this idea, they mostly think that income is the most important point to determine the area of residence, and a small number of people are status and origin.

I've seen too many people make a lot of money because they come up with a good idea, moving from the civilian area (southeast and southwest) to the villa area (due south) or even to the elite area (northeast and northwest), and they are all thinking about how they can make more money.

Of course, the method of making money must be formal, and those who make money in violation of regulations are not executed or locked up in a small black house, the Xia Dynasty has been established for more than 170 years, and many things have stabilized, and it is very low to find a way to make a lot of money.

In fact, in the Xia Dynasty, there was a very simple way to make a lot of money and change to a new home - to be an official.

The salaries of officials (including officers) in the Xia Dynasty were relatively high, the higher the rank, the salary would continue to increase, and the residence would be allocated according to the rank of the official, and the senior officials lived in the elite area, which was not bought by the senior officials, but was assigned to them to live, and when they retired or were resigned or demoted, they also needed to give up the mansion.

King Xia had a large number of properties in various parts of the Xia Dynasty, and King Xia often took out his real estate to reward officials and even non-officials, which was permanently rewarded, and basically would not be recycled, and all the people were proud to be rewarded by King Xia.

Being an official is a difficult thing and a simple thing, saying that the difficulty is calculated by the population of the Xia Dynasty, the total population of the Xia Dynasty is more than 1.2 billion, and the proportion of officials (including small officials, or all civil servants) in the total population is very low, and there will be an official among more than 150 people, and most of the officials are very low-grade officials and soldiers, and the grade from bottom to top is at least based on the decimal system.

To put it simply, all adults who have not violated serious laws can pass the examination to become officials, this examination is called the imperial examination, divided into liberal arts and martial arts, and there are detailed divisions within the liberal arts and martial arts, according to the number of people admitted to the imperial examination each year, the difficulty of the examination will also change, anyway, as long as you study carefully, you have a chance to pass the examination to become an official.

Only the children of the Long family are an exception, the children of the Long family directly become the rulers or managers of a place, and they do not need to pass the exam, all the people of the Xia Dynasty except the children of the Long family must participate in the exam, even those children of the family with a terrifying identity background must also participate in the exam.

This is something that Su Yan stipulates, passing the exam means that the person has a certain ability, if he can't even pass the exam, it can only be said that this person has no ability at all, how can he become an official, and a person who is incapable becomes an official, chaos arises.

Those with a background pass the exam to become a low-level official, at this time their identity background begins to work, compared with people without a background, they are easier to promote, but in general, it also depends on ability, people with a background but low ability are likely to be slower than those without a background but with high ability, meritocracy, the background of the children of the big family is just to give them some help.

In this case, there was hardly much class separation in the Xia Dynasty, and many times in the same restaurant, officials could talk loudly with merchants and workers during rest, as long as the two sides did not curse and did not have rebellion against the state, they could speak casually, and their speech was relatively free.

This is the Xia Dynasty built by Su Yan in hundreds of years, a relatively fair and harmonious Xia Dynasty.

……

Da! Da! Da!

A four-wheeled luxury carriage pulled by two white horses headed towards the palace of Zhongjing City, and the doors and windows of the carriage were installed with large pieces of glass that were once very expensive, and with the industrial production of glass, ordinary families in the Xia Dynasty used doors and windows with large pieces of glass.

However, the glass on this carriage is specially made, stronger than ordinary glass, not easy to break, and the glass is non-transparent, people outside can not see the people in the car through the glass, but people in the car can see the people outside through the glass, these properties make the glass on the carriage a hundred times the price of ordinary glass.

There were three people in the carriage, a middle-aged coachman, and two passengers in the carriage, one in green clothes and one in purple clothes, sitting diagonally opposite each other, it was Su Yan and Su Zi.

Su Yan put her eyes outside the car, looking at the scenery on the road, Su Zi's eyes were also put outside the car, but she often peeked at Su Yan, and then quickly turned her eyes away as if she was afraid of being seen by Su Yan, even if Su Zi knew that her son-in-law could feel her gaze, Su Zi still couldn't help but "secretly" put her eyes on Su Yan.

Su Zi was a little different from the previous dress on the bell tower, with a purple veil hat on her head, and the veil covered most of Su Zi's face.

Wearing a veil hat is a popular way of clothing and accessories in the Xia Dynasty a few decades ago, mainly those young women who have reached adulthood but are not married and have a certain status wear veil hats when they go out, covering most of their faces and preventing outsiders from easily seeing their faces.

Su Zi has a variety of identities such as maid, housekeeper, assistant, etc., but because of Su Yan's relationship, Su Zi has a relatively high status, and even the younger children of the Long family have to call Su Zi a sister, and they have great respect for Su Zi.

Soon, the carriage came to the front of the palace, not the main gate of the palace (south gate), but the side gate of the palace (east gate), the palace is the area of concern of all forces in the capital, Su Yan is unwilling to be paid too much attention by all forces, even if all the forces know that there is a person with an extraordinary status of "Su Yan".

The carriage stopped when it came to the east gate of the palace and did not continue to move forward, because the current Xia King Long Chi was standing at the east gate of the palace, and Su Zi had already sent someone to tell King Xia that Su Yan was going to come to the palace to discuss matters with King Xia, and the current King Xia was Su Yan's great-great-grandson, and with such a big gap in seniority, Long Chi could only honestly wait for his grandfather to arrive at the east gate.

It stands to reason that Long Chi should go to Su Yan's mansion in person, but Long Chi's movement from the palace as the king of Xia will be relatively large, so it is better for Su Yan to come to the palace.

Su Yan's seniority is so high that the juniors don't know what to call him, and Su Yan directly asks them all to call themselves grandfathers.

The carriage stopped, an old man and a middle-aged man stepped forward, the old man was full of silver hair, but he walked steadily, and his physical fitness was not much worse than other middle-aged people, he was the current Xia Wang Longchi, who was one hundred and nine years old this year, and according to his body, he was expected to live for twenty or thirty years, but he had decided that he would abdicate within two years and be succeeded by his eldest son Long Shao.

Obviously, the middle-aged man next to Long Chi is Long Shao, don't look at Long Shao as a middle-aged person, in fact, Long Shao is eighty-three years old.

Very helpless thing, Su Yan was already a hundred years old when he abdicated, and Long Ping was seventy-seven years old when he took over the throne, and every Xia King took the initiative to abdicate, but the age of the new Xia King when he took over was very high compared to others, and it was difficult for others to live to this age, but the age at which the new Xia King ascended the throne was already so old.

Fortunately, the children of the Long family are all famous for their longevity, and there are some good aspects of ascending the throne at an older age, at least after so many years, the new king is absolutely stable.

It has been more than 170 years since the founding of the Xia Dynasty, and everyone knows the longevity of the children of the Long family, and those who are close to them even know the reason for the longevity of the children of the Long family.

Who doesn't admire immortality, Su Yan was worried that there would be forces that would hit the Long family's disciples with thoughts because of the longevity of the Long family's disciples, so he threw out some simple martial arts exercises early, mainly health preservation exercises, and let those people learn and practice.

Many people have a higher lifespan because of martial arts, but there are almost no lifespans of more than a hundred, without the support of high-year medicinal materials, it is very difficult to have a higher entry in the martial arts, and most of the high-year medicinal materials in the Xia Dynasty are under the control of the Long Clan.
