The square is surrounded by a wall of the square, four doors are opened, and there are cross streets in the square, and the cross streets and smaller cross alleys divide the whole square into sixteen districts. The supervision system is implemented in the workshop, and the management is strict. Commercial activities are restricted to the eastern and western cities, which are also closed.

This kind of planning of placing the palace city and the government office area in the northwest corner of the city and adopting a square layout was mostly adopted by the local prefectures and counties at that time and even in later generations.

The area of large and medium-sized state capital cities and county towns is generally equivalent to the area of 16 squares, 4 squares and even one square in the Beijing Division, and the layout is roughly the same, that is, a gate is opened in the middle of each side of the city that is roughly square, and the whole city is divided into four districts with cross streets in the city, and the number of squares in each district varies according to the order of the state capital and county. In each district, there are small cross streets and smaller cross lanes. The planning of layers of cross streets and alleys is one of the characteristics of the layout of the city site in the Sui and Tang dynasties, reflecting the unique urban form of the feudal hierarchy.

At the same time, it is clear enough, at least it is much better than the messy layout of the past, and the infrastructure can also be built according to the number of squares.

For such an architectural pattern, I can only be deeply impressed, and the current population of Chang'an City is not much, in the ninth year of the Sui Dynasty, the "Sui Book and Geographical Chronicles" recorded: Jingzhao County has 308,499 households, and each household has a population of more than five people, even if it is calculated according to 5.5 people, the population of the entire Jingzhao County is 1.69 million.

The Sui Dynasty set up Jingzhao County, which was established as a county-level system to unify more than 21 counties such as Chang'an and Daxing. The long-term resident population of Chang'an City in the ninth year of the great cause has reached the scale of 500,000, coupled with the natural increase over the years, coupled with the chaos in the world, the general environment of Guanzhong'an has made the resident population of Chang'an City grow day by day.

But even so, there are still many places that are empty, and these are naturally for the sake of giving rewards to those princes, grandsons, princes and nobles in the future.

At present, according to the location of the eight fire squadrons, in these eight square cities, hospitals, tax offices, primary and secondary schools, theaters, and public toilets have been set up.

Well, the two institutions that have already been set up are the fire squadron and the tax office, and the others are still recruiting personnel for preparation and construction. However, the public toilet, this son is going to build one in every square. No one wants Chang'an, a magnificent and majestic historical giant city, to be full of yellow mounds or puddles of dirt in the streets and corners.

After thousands of years, when the excavation and research work of Chang'an City was carried out, a lump of fecal fossils was excavated, which was too strange.

And all the public toilets flow into the unified sewage treatment system of each district, that is, the septic tank, but this son made it out before the farmer watched them repair the house, and he also invited the technician in the town to guide and make it, anyway, it is a bit similar to the biogas tank. That's what the magician said.

As early as in Hancheng County, Ben Gongzi designed the drawings according to the three-grid septic tank in later generations and handed them over to those construction personnel to build according to them. The so-called three-grid septic tank is composed of three pools that are connected, and the middle is connected by a fecal pipe, mainly using the principle of anaerobic fermentation, the proportion of the middle layer of fecal and parasite eggs is greater than the specific gravity of the general mixture and easy to precipitate, the feces are fermented and decomposed in the pool for more than 30 days, and the middle layer of fecal liquid flows from the first pool to the third pool in turn, so as to achieve the purpose of precipitating or killing the parasite eggs and intestinal pathogenic bacteria in the feces, and the fecal liquid of the third pool becomes a high-quality chemical fertilizer.

There is no way, there is no chemical fertilizer in this era, and there is only farmhouse fertilizer that can be found to get it, and the farmhouse fertilizer in this era is often very incomplete, so the fertility is not enough, and the parasite eggs and intestinal pathogenic bacteria in those feces have not yet been hiccuped, which is likely to cause re-infection of the disease.

So when Hancheng County built these septic tanks on a large scale, the people often complained about it, but when the effect came out, those guys cried and shouted hoping to help their families build such things.

Nowadays, every household in this era uses a commode, that is, night incense, and someone will come to collect it. Nowadays, there is no need to be so troublesome, all of them are poured into the septic tank of each square, and only two staff members are busy to ensure the neatness and cleanliness of the entire square area.

And the public health system is naturally more than that. After the capital of this son, Chang'an City has begun to dig deep and dig hard, naturally according to the example of Hancheng County to get the sewer project.

Sewers are a type of urban public facility that has been used as early as the ancient Roman period. The prototype of modern sewers originated in Paris, France, and Paris still has the largest urban sewer system in the world. Generally speaking, the sewer system is used to collect and discharge domestic wastewater generated in the city and industrial wastewater, as well as rainwater.

The most magnificent sewer in the ancient world is the Roman Maxim sewer, ancient Rome was extremely clever in terms of public facilities, and was also proficient in the construction of public facilities, until 315 AD, there were more than 140 public toilets in Rome.

Even the sociable Romans developed public toilets as places of recreation and recreation, and like public baths, for a small fee, people could gather in the public toilets and engage in natural behaviors such as gossiping with neighbors, planning gatherings, discussing politics, or engaging in business.

Anyway, I can't believe that there are people who use public toilets as entertainment venues, and if it is a bathhouse, it is almost the same, but from this point of view, the ancient Romans were indeed very sociable, and they could brag and fart when squatting.

Yes, in the later generations, I read the history of the world, and for the ancient civilization, this son studied it quite carefully. The ancient Greeks had profound attainments in philosophical thought, history, architecture, science, literature, drama, sculpture and many other aspects. After the demise of ancient Greece, this civilizational heritage was destructively perpetuated by the ancient Romans, thus becoming the spiritual source of the entire Western civilization.

And ancient Rome in the construction of public facilities, is beyond the predecessors, the proportion of public buildings in the ancient Roman city is very amazing, a large number of Colosseum, baths, theaters, libraries and public spaces and markets, the use of these public facilities, in most cases is free, all urban pleasures are provided by the city, the ancient Roman city not only provides citizens with "urban space", but more importantly, provides "public life".

In complete contrast to the long Middle Ages, which belonged to the "city of the gods", ancient Rome can be said to be a "city of citizens". On the other hand, the Gentiles or subordinate provinces only had a weak sense of worship for ancient Rome, and the urban construction and social life of ancient Rome were completely unimaginable in that era. "When the Colosseum stands, Rome will exist" – any enemy of ancient Rome, after witnessing the incredible construction of ancient Rome and the naked strength and slaughter of the Colosseum, will agree in their hearts that Rome is invincible and will not dare to rebel against the tyrannical rule again.

The ancient Roman city was a discursive medium that drove the citizens of the city crazy and the enemies outside the city fearful. For the first time, ancient Rome showed the charm of urban civilization in front of the wild world - population gathering is not really a city, only the great prosperity of space and public life, the power that makes citizens cheer and outsiders shock, is the foundation of the concept of the city, and it is also the secret of the ancient Romans to make the city great.

However, what I admire most about these barbarians is their drainage system, and the Romans built the most magnificent sewer in the ancient world, the Maxim sewer built by the Idalarians for Rome BC. The Idalarians flourished in north-central Italy between the 8th and 6th centuries BC, and the rise of Rome led to their eventual assimilation into the Roman Empire.

Around the sixth century B.C., the Idalarians dug the sewers that drained into the Tiber River, the main channel was more than sixteen feet wide, and was later expanded for the Romans. The seven branches of the sewer flow through the city streets and eventually merge into the main road, the Maxim sewer. When a storm comes, the sewers are cleaned by the tremendous force of the flowing water. The Roman scholar Pliny hailed it as Rome's "most remarkable achievement". More than 2,500 years after its construction, the sewer was still in use in Rome in the 21st century.

And in the land of China, even in the 21st century of modernization, our drainage system is simply a luxury that we dare not have, and the newly built road sections that can be seen everywhere in the city, even the pavement that has just been paved with floor tiles, may be dug up the next day.

Why? Naturally, it is to facilitate the production and life of the people, what a warm and reason. Under the sidewalk, many horizontal pipelines belong to various management departments, and they are in their own ways in construction and maintenance, messy and wasteful, and it is common to see the same road section constantly being dug up and buried by this department, and soon being dug up again by another department.

China's drainage system is not learned from the West, but learned from the Soviet big brother, the drainage system built by the hands of the big brother, and then copied to the land of China, this kind of drainage pipe is about to be climbed by people, anyway, I have not seen anyone dare to really drill in, and even in the city where I lived, I saw the drainage pipe that was only not much thicker than the waist, so the impact of such a small-caliber drainage pipe is that we have a place, the light rain is nothing, and the heavy rain is pouring as a swimming pool.

I remember seeing the news broadcast that Beijing was flooded, and I finally had a sense of accomplishment at that time, and I never imagined that Beijingers would have the same experience as people in a small town like me. The square is surrounded by a wall of the square, four doors are opened, and there are cross streets in the square, and the cross streets and smaller cross alleys divide the whole square into sixteen districts. The supervision system is implemented in the workshop, and the management is strict. Commercial activities are restricted to the eastern and western cities, which are also closed.
