Problems are piled up, and to fundamentally solve the problem, the Ministry of Works' opinion is to not only silt and dredge the waterways and ditches in the capital, but also form a long-term system to avoid accumulating small amounts and having to deal with them. After Zhao Bing looked at it, he felt that it was necessary to plan the overall situation, and it was not just a headache to treat the head and feet. In this way, the fundamental problem could not be solved.

Zhao Bing checked the old files and found the city map of Hangzhou after the imperial court moved south. He found that the ancients also had the idea of ​​big planning and strictly planned the city. However, more than a hundred years later, with the increase in population and the changes in the city, there was no modification, resulting in a chaotic situation.

Lin'an City is a water town city, facing the Qiantang River in the east, the south, and the Grand Canal in the northwest. With rivers as the main trunk and combined with other large and small river channels in the suburbs, a large water transportation network around the city is formed. The overall layout of Lin'an City is to give full play to the advantages of the water town city, with Lin'an City as the center, this water transportation network as the main vein, and cooperates with the Jingji Post Road, gathering a series of large and small satellite towns and the port of Zepu in the surrounding suburbs.

The satellite towns in the suburbs of Lin'an are all built by the Linjiang River. These towns use the convenience of river shipping to connect with Lin'an cities and become economic bridges that connect Lin'an cities with the vast suburbs and rural areas and surrounding cities. The sizes of each town vary in size, such as Jiangzhangqiao and Kuangping, and the scales are quite impressive. In addition to the suburbs of Chi County, there is also the Lin'an seaport. Although this town is not under the jurisdiction of Chi County, it is a Lin'an foreign trade port, and can be directly connected to Lin'an City from Qiantang River. This port town is an important gateway to Lin'an city and should become the seaport area of ​​Lin'an City.

There are three main rivers in the city, Maoshan River, Yanqiao River and Longshan River, to maintain shipping in the city. Later, due to the construction of the Deshou Palace and the continuous invasion of rivers on both sides of the river, the Maoshan River became increasingly blocked, and the water transportation in the city was mainly Yanqiao River, which was connected to the Longshan River outside the southern city. After Zhao Bing chose the Beigong as the palace, Maoshan River was dredged again, but it was difficult to reappear the scale of the day, so he could only pass small boats.

Roads are not only a transportation line for a city, but also have the function of dividing the city. Since Lin'an's urban shape is long in the north and south, narrow in the east and west. In addition, the undulating terrain and lateral rivers, the urban road layout has to adapt to the requirements of these conditions. In general, Zhao Bing's perspective, the urban road network structure of Lin'an is basically planned according to the meridian and latitude map.

Due to the limitations of the specific conditions in Lin'an, there are many roads running east-west and few roads running north-south. Secondly, the roads are often tortuous, and even the main roads are difficult to straighten. Some roads are evenly composed of sections. As for the spacing of the main roads, the situation is more complicated. Except for the relatively uniform spacing of some streets and alleys in the western part of the middle section of Yu Street, most of the others are different from each other.

The main roads of the road network on Yujie are also the north-south main axis planned by the whole city, starting from the north and Ningmen of the old imperial city in the south and reaching the slanting bridge in front of Jingling Palace in the north. There are four north-south roads roughly parallel to Yujie. One road is longer and is the north-south main road in the western half of the city. The second and three are located in the east of Yujie, between Xiaohe and Taihe, and are composed of two sections. The second road starts from Chaotianmen in the south and reaches the east Chunfeng Tower of Zhong'an Bridge in the north. The third is the south-Water East Zhonggong Bridge to the west of Yanqiao. The fourth road in the east of Yujie is from the south-Water East around Deshou Palace and to Changlefang in the north. These three roads are all connected to the district-to-connected roads between the Qingbomen to the east-west main roads and Qiantangmen to the east-west main roads of Dongqingmen, rather than the main roads that run through the north-south main roads of the city.

There are four main roads in the east and west. The first one is Houchaomen to Qiantang Gate; the second one is from Xinmen to Qingpo Gate; the third one is from Chongxin Gate to Fengyu Gate; the fourth one is from Dongqing Gate to Qiantang Gate. These four roads are all main roads that span the Yu Street and connect the city gates corresponding to the east and west. In addition, since Lin'an is a water network city, there are many bridges and beams on the roads. Among these bridges, except for Zhong'an Bridge and Guan Bridge, which are flat-girder bridges, the rest are basically arch bridges, and boats can be connected under the bridge.

Since Lin'an decided to be the leader, the Central Plains people who followed Emperor Gaozong's royal family, noble relatives, ministers, and military subordinates went south to Lin'an one after another. In order to resettle a large number of people coming from the south, they had to move the original indigenous people outside the city, which led to the sudden increase in the population of suburbans in Shaoxing. Due to the sudden concentration of population in the city, most of the people coming from the south were royal families, noble relatives, prominent officials, and wealthy businessmen, which would inevitably cause changes in the class structure of urban residents. This change must also be reflected in the planning of residential areas.

Lin'an residential areas can be divided into two categories. The first category is the mansion area, which includes the emperor's residence, royal family and noble family, and royal ministers' residence, and various official houses are also attached to this category. The second category is general residential areas, that is, residential areas for residents of all classes of the city. It is arranged according to the production of alleys and alleys. Not only are there urban residential houses, but also commercial outlets in the streets and alleys, forming a unified integration of city and yards.

There are two types of mansion areas in Lin'an City. The first area is west of Yujie, and the second area is east of Yujie. The first area is wider, starting from Qinghefang in the south, along the Qinghu River to the north, and extending to the south of Wulinfang near Guanqiao. Some areas in the meantime are parallel to local administrative areas and general residential areas, resulting in an intermittent trend. The second area is east of Yujie and Yanqiao River. north of Deshou Palace, south of Fengle Bridge, and in the east of Fenglefang. This area is smaller and mainly serves as the residences of royal relatives and nobles. Therefore, this area is relatively neat and does not intersect with other areas.

Generally, residential areas are based on Yu Street and can be divided into two districts. The east of Yu Street, north of Xinmen, south of Baiyangchi, and in the narrow area between the Shihe and Yanqiao River, is the first residential area. The west of Yu Street, south of Qiantangmen, and north of Fengyumen, and between the central commercial area and the local administrative area is the second residential area. Some areas of this area are intertwined with the mansion area, so they are not as regular as the first residential area. Outside these two districts, there are also residential alleys interspersed in the corner of the city.

Due to the scale of the streets and alleys in the Song Dynasty, the streets and alleys have the characteristics of commercial outlets. The streets and alleys are actually Lin'an urban organization and management units. There are chases on the streets and alleys, and the chassis is still in the Baojia system of the Northern Song Dynasty. In it, shops can be opened and some industry grassroots outlets closely related to residents' daily lives. These grassroots commercial outlets distributed in the streets and alleys are not only the grassroots organizations of the commercial network, but also an integral part of the streets and alleys, and schools are also set up.

However, generally residential areas have a high population density and high building density. These two residential areas are adjacent to downtowns, so some alleys have more shops. Therefore, fire management has become a crucial issue. After building their own capital, in order to strengthen urban fire protection, on the one hand, on the one hand, on the other hand, there are mostly empty spaces in front of important buildings and in the city where people are more crowded, and squares are set up. Military patrol shops are also set up. Stone tower-type collapsed houses are also built in the alleys to prepare residents to store important items during fire alarms. The construction of the alleys does not build a table. It is also related to fire protection requirements.

In addition, as a capital of a country and a commercial capital, Lin'an City must also have palace areas, central and local administrative areas, granaries, wharfs, handicraft areas, cultural and educational areas, urban defense areas and scenic areas. However, some areas have been adjusted accordingly since Zhao Bing. First of all, due to malicious destruction by the Mongolian Yuan Dynasty, Zhao Bing moved the Imperial Academy and Martial Arts capitals there from the north of the city to this place.

In addition to the renovation of the military villages around the city, the city defense zone concentrated the past military camp from outside the Dongjiang River to the old imperial city. In addition, he also planned to move some of the granaries to this area. The handicraft zones, commercial zones and residential zones have basically remained unchanged, but these two areas have now become the main source of urban pollution and are also the long-standing areas for governance.

Zhao Bing communicated several times with the Ministry of Works. He planned to move the military industry and handicraft areas out because this was not only a pollution problem, but also a threat to urban safety. At present, the military industry workshops no longer produced cold weapons such as crossbows and guns, but involved gunpowder manufacturing and various explosives powered by gunpowder. In addition, if an accident occurs in the neighboring residential area, it will be earth-shaking and causing great casualties. He still remembers that similar accidents occurred in the capital of the Ming Dynasty, which resulted in thousands of houses being destroyed and countless casualties. As for how it happened, it has become an insolvent mystery.

Handicrafts are mainly divided into official and private. The official business includes Shaofu, which will work, printing and ceramics, which are basically industries that serve the palace, maintain the needs of the royal family, and are also close to the palace. The private business is mainly silk weaving workshops and printing workshops, concentrated in Sanqiao, Xifang and Muqinfang, and Pengqiao's residential areas, which aggravates the pollution in residential areas.

At present, handicraft workshops need convenient transportation and near water. After some discussion, Zhao Bing decided to go all the handicraft zones and military production to the original city defense zone in the east of the city, which is close to Qiantang River and is in the downstream. The pollution to urban water sources can be minimized, and the riverside can be conveniently transferred from the waterway and sent to various places. He also wanted to re-refine the partition during the relocation, especially military-related workshops, which can be upgraded and transformed, increase the application of new technologies, and increase production.

Next, Zhao Bing decided to harden and widen the main and secondary roads in the city to achieve the thirty-step width as previously regulated, and at the same time improve the drainage road system. The project seems not complicated, but it is not small, because the current street invasion phenomenon is serious, and to broaden the road, those illegal buildings must be demolished first. Demolition is a difficult problem that is easy to intensify contradictions in modern times. It also existed in the Song Dynasty, and the difficulty is so high that it often ends in vain.

As Zhao Bing knew, there was a phenomenon of invasion of streets in Kaifeng. When the capital of Kaifeng was established, invasion of streets not only made the streets narrow, but also caused the streets to be tortuous. Therefore, the court started to control the invasion of streets from these two aspects. On the one hand, the streets were straightened, and on the other hand, it stipulated that the streets must be wide to thirty steps. However, the phenomenon of invasion of streets was even more serious.

There is such a material in "The Successful Zizhi Tongjian Changbian": Quxiang in the capital city is narrow, (Zhenzong) ordered the right attendant to serve the monarch, and the chief marquis of the cabinet and Xie Dequan Guangzhi. After Dequan received the imperial edict, he first removed the noble and asked the residence. The discussion was complicated and there was an imperial edict to stop him. Dequan asked in person: "Now those who are worried about the matter are all powerful people, and they are stingy in the house and the house are worthy of their own resources. If there is no such thing, I dare not follow the imperial edict." The emperor had no choice but to follow it.

Look at the time when Emperor Zhenzong of Song issued an edict to demolish the buildings invading the streets, but was boycotted by the "prime and important" major families, and the emperor had to take back the order. However, the phenomenon of invading the streets was too serious, especially the "those who were in trouble were all powerful and powerful", which forced Xie Dequan, who was determined to be on the streets, to die. The biggest resistance came from those in power. At that time, the most serious invasion was the residence opened by the former prime minister Xia Shun. The governor Zhou Zhan was falsely accused of disturbing the people during the rectification, so that he was transferred from his county and moved to the governor of Xiangzhou.

During the Zhezong Dynasty, Fan Zuyu wrote a letter to Emperor Song, pointing out: "There is a company that destroyed houses too much, and the residents are not unavailable. Even though the people invaded the streets and built houses, they dare not complain." They thought that if they were ordered to demolish houses, they would not cause resentment, so as not to cause unrest and public grievances. As a result, roads and bridges were occupied by public and private houses, merchants and shops, which greatly damaged the urban environment of the Song Dynasty.

After crossing the south, the phenomenon of invasion of streets was even better than that of the Northern Song Dynasty. The scene in Lin'an City was "the city was vast, the household registration was rich, the houses were high, the eaves were connected, the streets were blocked, the streets were blocked, and the streets were narrow, which was unbearable." Some people in later generations once said that it was not "to demolish houses", which led to the prosperity of the capital of the Song Dynasty. However, Zhao Bing believed that the widespread existence of streets was affected by the excessive pursuit of money and interests in the Song Dynasty. While the economy was prosperous, it caused the result of chaos and disorder in the city. From a development perspective, it was not worth the loss.

The same result will also be produced by managing the river. According to Zhao Bing's plan, the Maoshan River, which has been severely silted, is transformed from the Ming River into a crypt. Of course, it must also be silted, built and covered, as the main pipeline for urban drainage, and then the sewage from various places is collected here through branch roads and discharged from the city.

According to Zhao Bing's vision, this culvert should be used as a century-old project, with sufficient internal leniency, and the regulations can be comparable to the underground pipelines in Berlin, Germany in modern Germany. The culvert can be used for sewage discharge, and the accumulated water in the city can be discharged out of the city when encountering floods to prevent the occurrence of internal waterlogging. Of course, it can also play a role in preventing enemy water attacks in the military.

At the same time as the urban renovation project begins, residential areas must be upgraded and renovated. The first thing is to turn the "doi well" into a "ceramic well" to prevent water pollution. In addition, the regulations on centralized garbage storage, cleaning, street cleaning and other regulations must be carried out at the same time, and a long-term mechanism will be formed. The problem follows. There is no urban management in this era, so Zhao Bing must also consider establishing such a "great" army 800 years ago.
