After saving the money, Li Jing took everyone to his shop in Jinling to settle down with luggage, the Li family's shop is on the northwest bank of the Qinhuai River, and they will immediately go to the inner city (capital) Xishui to close the city gate, this place. Along the riverbank road, the area is not small, but the location is a bit too remote, near the Xishuiguan where the Qinhuai River is about to flow out of the city wall, it is not a bustling commercial area, and it is also far away from the Confucius Temple. But fortunately, there is a stone arch bridge that connects the two sides. The east of the river is a prosperous urban area, and from this pontoon bridge along the Qinhuai River to the southeast is the legendary ten-mile Qinhuai. But across the river, the price of land is very different. And the inner side is the most prosperous area of Nanjing, Sanshan Street, Dagongfang is inhabited by nobles, officials, and senior military attachés.

After settling down, Li Jing found a map of Jinling and began to carefully study the urban layout of Nanjing. This will be an important fulcrum for Li Jing's future development in the future. In the next 24 years, the north of the Yangtze River will be in turmoil, and the south of the Yangtze River will remain peaceful. It was not until the Qing soldiers went south to break through Yangzhou that the soldiers pointed directly at the south of the Yangtze River.

The city of Nanjing in the Ming Dynasty is a rare and irregularly shaped city in Chinese history, which is divided into four parts: the outer city, the inner city (the capital), the palace city, and the imperial city. The outer wall is large and roughly a square, except that the western and southern walls are wavy. The walls along the Yangtze River in the east and north are straight. Because there are Zhongshan Mountain, Xuanwu Lake and Mochou Lake in the inner city, the inner city is squeezed on both sides, and the inner city presents a gourd shape with a gourd mouth rushing to the north, and the two waists are Mochou Lake and Xuanwu Lake. The bottom of the gourd is larger, and the east corner of the city wall is against Zhongshan. The Imperial City is built in the middle of Xuanwu Lake and Zhongshan to the south, and it is very square, and the palace city is in the imperial city, just like Beijing.

The main gate of the imperial city is called Hongwu Gate, and it is Zhengyang Gate to the south straight out of Hongwu Gate, which is also the south gate of the inner city of Nanjing. The upper reaches of the Qinhuai River flow from southeast to northwest here. It flows directly south of the U-shaped city wall of Zhengyangmen. There is a bridge on the river, called Zhonghe Bridge, and after crossing the Zhonghe Bridge, it is the main gate of the capital, Zhengyangmen.

It can be understood in this way, regardless of the outer city surrounded by the outer city, the eastern part of the inner city probably accounts for one-fifth of the area of the inner city is very regular, from the Zhengyang Gate into the inner city, not far from the main gate of the imperial city Hongwu Gate. Further inside are the palace castle and the harem, and the imperial city and the palace castle are strictly rectangular walls. The south and east sides of the imperial city are not far from the inner city wall, and the east gate of the inner city is called Chaoyang Gate. Not far from the west side of the Imperial City, there is a north-south street called Taiping Street that runs parallel to the west wall of the Imperial City, and this street is so long that it directly separates the rest of the inner city from the Imperial City. The imperial city is very small because there are Zhongshan Mountain and Taiping Lake in the north, so it cannot be expanded to the north. The western half of the inner city stretches all the way to the Yangtze River. The inner city looked like a pregnant woman, and the small area on the east side of Taiping Street, that is, the part where the imperial palace and the central government of the imperial court were concentrated, was the bulging belly.

The Qinhuai River continues southwest outside the south gate of the inner city and flows into the inner city of Nanjing through the water pass, forming a U-shape, and then flows out of the inner city from the west water pass. In the inner city, the flow is exactly ten miles of road, so it is called ten miles of Qinhuai. These ten miles of Hebei flow through Nanjing Gongyuan (imperial examination room), Nanjing Guozijian (Jiangning Fuxue in the Qing Dynasty), Qian Workshop and so on. These gentlemen who read live in Hebei, and across the river is a street of Qing/Lou in Qinhuai, ten miles away. It is equivalent to Sanlitun or Houhai Bar Street at the end of the Ming Dynasty.

The west side of the inner city is the main body, and the south gate of this part is called Jubao Gate. Entering the west side of the Jubao Gate is Fengtai, and it is the top of the U-shape of the Qinhuai River in the inner city all the way around. There is a bridge here called Qianhuai Bridge, and after the bridge is a long north-south street like Taiping Street. This street is the central street of the inner city, and at the northern end of this street is Yingtianfu, the city government of Jinling, to the west, and to the east is Cheng'en Temple.

The size of the inner city is only about a quarter of the size of the outer city, and the size of the imperial city is only about one-tenth of the size of the inner city. There are noon gates, Dong'an, Xi'an, and Bei'anmen. Surrounded by a moat. The main gate on the south side is called "Hongwu Gate", and behind it is a wide imperial road that runs through the north and south. At the end of the royal road is the "Outer Five Dragons Bridge", and to the north of the bridge is the "Purple City". The main gate of the "Purple City" is the Chengtian Gate. Then came the end gate and the noon gate.

To the east of Chengtianmen, Duanmen and Wumen, there is a temple dedicated to the emperor's ancestors, and to the west there is a shrine altar dedicated to the god who dominates the fate of the country. Inside the noon gate is the "front court". The three main halls located on the central axis are the "Fengtian Palace", the "Huagai Palace" and the "Jinshen Palace", commonly known as the "Three Great Palaces". To the east of the three major halls is the "Wenhua Palace", to the west is the "Wuying Palace", and there are the symmetrical "Wenlou" and "Wulou". On the east side of the Wenhua Palace, there is the "Donghua Gate", and on the west side of the Wuying Palace, there is the "Xihua Gate".

To the north of the three halls is the "Houting" - the place where the emperor lived in his daily life, including the Fengxian Palace, the Rouyi Palace, the Chunhe Palace, the Qianqing Palace, the Kunning Palace, and the Imperial Garden, until the Yudai River in the Houzaimun.

But the location of the Imperial City and the Imperial City is located on the eastern edge of the bottom of this gourd-shaped inner city as a whole. It belongs to the corners of the inner city. However, Taiping Street, which separates the Imperial Palace from the central government office and the main inner city from east to west, is also quiet. It is also easy to manage. The people were scattered and scattered, and there was nothing to do, so they walked to the east side of Taiping Street.

The walls of the inner city, the imperial city, and the palace city are real rammed earth and brick solid walls, although irregular, but they are all built by relying on the terrain, mountains, lakes, and rivers. The outer kingdom is an earthen city, which mostly relies on the natural formation of hills and hills, and only in the weak parts is the brick and the city gate is built. Among them, the inner city (capital) city wall winds for 35.3 kilometers, which is the largest existing city wall in China, and the largest city wall in the world, and has been selected as the world's largest city wall by the World Record Association, and the outer city wall outside the capital is more than 60 kilometers, which is the largest in world history. Nanjing Ming City Wall was built in 1366 (Yuan to Zheng 26 years), all completed in 1393 (Ming Hongwu 26 years), the use of the country's 1 department, 3 Wei, 5 provinces, 37 prefectures, 152 prefectures and counties a total of 280,000 workers, at the same time in the five provinces to burn city bricks, the use of about 350 million city bricks, lasted 28 years, and finally completed the pattern of the four city walls of Beijing Shiying Tianfu.

Originally, the inner city was not prepared to build the outer Guo, Ming Taizu Zhu Yuanzhang spent more than 20 years, using more than 200,000 craftsmen to build the city wall, the built area of 43 square kilometers, the total length of the capital city wall is 35.267 kilometers kilometers, including the Jiankang City of the Six Dynasties and the Jinling City of the Southern Tang Dynasty, 14-26 meters high, 2.6 meters wide at the narrowest point, 19.75 meters at the widest point, about 14.5 meters wide at the bottom, 13,616 battlements, 200 majestic strong cities.

In the twenty-third year of Hongwu in the Ming Dynasty (1390), after the construction of the capital city was completed, Zhu Yuanzhang and the ministers and princes of Zhu Yuanzhang climbed to Zhongshan to observe the shape of Nanjing City.

At the same time, Yuhuatai in the south of Nanjing and Shogunate Mountain in the north remained outside the city, which was extremely unfavorable to the defense of the capital.

Then Zhu Yuanzhang ordered the construction of the outer Guo city wall, in order to make up for the shortcomings of the capital city wall, the outer Guo is called 180 miles, in fact, about 60 kilometers. The brick-built sections add up to about 40 li, and the height of the outer earthen castle is about 8-10 meters, and the width of the upper part is 6-8 meters. In the twenty-sixth year of Hongwu in the Ming Dynasty (1393), the four walls of the Ming City Wall of Nanjing were completed.

After all, the Li family is a local gentry who is not in the stream, and there is no comparison with the great gentry in the south of the Yangtze River, so it is not easy to find a cost-effective place in the corner of the inner city of Jinling City. And this place is the core city across the river. To the east is the red-light district. To the south is Fengtai. This triangular place has a place, and it can be regarded as the best choice for the Li family to get their hands on.

Li Jing handed over the vegetable oil to the old shopkeeper, because at the end of the year, the retail sales of vegetable oil have risen to three and a half cents of silver, and 100,000 catties of oil and three cents of silver a pound of wholesale to major grain and oil stores and hawkers walking the streets and alleys, the sales are hot, the output of this era is low, and the supply of materials for the New Year's holidays is relatively tight. So it sold out in three days. The net profit of 20,000 taels has been received, and 30,000 taels of silver are deposited into the money bank through Li Zhe.

Previously, he endorsed the credit of the Li family from large and small vendors, and purchased 36,000 taels of silver for half a year's inventory of rapeseed on credit, but this time Li Jing added 10,000 taels himself, a total of 40,000 taels were remitted back to Taohuawu, and 36,000 taels were returned to the payment. Four thousand taels were handed over to Lao Wu for management as the working capital of the oil mill.

Li Zhe's eyes were full of ingots in his excited eyes, this thigh had only been hugged for less than five days, and there was a business of 40,000 taels, Li Zhe handed over the other customers to his men and ran the street this time, and he followed Li Jing to serve without doing anything.

The Li family's industry is a row of small buildings facing the street, each with three doors and three deep. Along the riverside path on the north side of the Qinhuai River, the river embankment is lined with green willows, and the environment is elegant. Li Jing counted it, there were eleven buildings in total, and the buildings were close to each other. Li Jing was very strange, why didn't he build a row and save materials, so he had to use two walls in one of the three rooms.

The old shopkeeper Li Deshui introduced: "My dynasty is very hierarchical in terms of the hierarchy of the first house. In the twenty-sixth year of Hongwu (1393 AD), it was customized: five and nine official halls of the first and second grades, seven of the three official halls of the sixth to ninth grades, and three of the main entrances; down to the Jiupin official hall with three rooms and seven frames; There are no more than three rooms and five frames in the common people's houses, and it is forbidden to fight and color. The main hall of the common people shall not exceed three rooms and five seats. ”

"Hongwu reiterated in the 30th year: there can be as many as one or twenty houses, but the number of rooms and shelves cannot be increased. In the twelfth year of Orthodoxy (1447 AD), the number of frames could be increased, but the number of intervals could not be changed. The grade of the dwelling is mainly limited to the number of rooms and shelves, and the number of building floors can be adapted to local conditions. ”

Li Jing's grandfather was a five-rank official from the Jingshi Hanlin Academy, and his father, Jingshi Shuntianfu, was a sixth-grade official. Li Jing thought about it for a while, and probably understood the low-key meaning of the Li family in this southern capital, where the dragon and the tiger were hidden.
