How many parts will Nanjing Miyagi be divided into after its completion?

After the completion of Nanjing Miyagi, it is 2500 meters long from north to south and 2000 meters wide from east to west. The plane is rectangular, facing south, and it is divided into two parts: three halls and six palaces. The gates of Miyagi City Wall include the Meridian Gate, the Left Gate, the Right Yemen Gate, the Donghuamen Gate, the Xihuamen Gate and the Xuanwu Gate.

The imperial city is the nearest wall to protect Miyagi. There are Hongwumen, Chang 'an Left Gate, Chang 'an Right Gate, Dong 'anmen, Xi 'anmen and Bei 'anmen on the wall.

Outside the imperial city, there are also capital city walls to strengthen defense. The southeast corner of this part of the capital is connected with the old city of Jinling in the Song and Yuan Dynasties near Tongjimen.

After the completion of the Imperial City, Zhu Yuanzhang set out to widen the capital to the north. But at the beginning, he still couldn't make up his mind whether to build it westward along Zhoushan on the south bank of Xuanwu Lake and the northern wall of Jiankang City in the Six Dynasties at the foot of Jilong Mountain, or northward along the west bank of Xuanwu Lake.

At first, he tended to use the north wall of Jiankang City to extend westward to the Drum Tower and Liang Qing. A section of the wall behind Jiming Temple was commonly known as "Taicheng" in the Six Dynasties. It was reinforced and rebuilt in the Ming Dynasty and ended at the northern foot of Jilong Mountain. According to this plan, the capital of the early Ming Dynasty will be only 2/3 of its size.

Why are the patterns of Nanjing city walls rare?

Kings in China used to use squares to build their capitals, but the Ming city violated the ancient system and showed an irregular shape, which was formed by mountainous terrain. It widens and heightens the city walls in the south and west of the capital of the Southern Tang Dynasty, extends eastward and westward, and then closes.

Regarding the shape of Nanjing city wall, there are some sayings such as gourd shape, palace fan shape and zongzi shape, and some even say it looks like Zhu Yuanzhang's face. In fact, the construction of the ancient capital of China pays attention to geomantic omen. They highlight the sanctity, orthodoxy and mystery of imperial power through the theories of law, image, heaven and earth and the center of the universe.

The overall layout of the Ming City Wall in Nanjing is the intersection of the "North-South Fight" and the "Big Dipper". Because the Big Dipper is seven stars and the Southern Dipper is six stars, Nanjing has 13 gates.

For example, the layout of Miyagi is based on Ziwei Garden where Ziwei Star is located, followed by Gai Huaxing, and there is also Gai Hua Hall behind the most important palace in Miyagi. The trend of Jinshui in Miyagi is exactly the same as that in the Milky Way.

The imperial city is arranged according to Taiwei Courtyard, which is mainly composed of ten stars. The Imperial Capital also has five departments of officials, households, ceremonies, soldiers and workers on both sides of the Imperial Road, and the five armies in the middle, left, right, front and back are governors. Duanmen Star is the south gate of Taiwei Courtyard, and the Imperial City also has Duanmen.

The capital is designed according to the wall of Shi Tian. The most typical example is that punishments are not in the imperial city with the other five departments, but are placed outside the emergency exit in the north of the imperial city with Dali Temple and Duchayuan, corresponding to the stars in the Shi Tian city wall, that is, the heavenly prison.

According to Ming Taizu's records, Zhu Yuanzhang said, "I want to see the sky at night. If a meteor passes through Guansuo Star, it means that there is an unjust case, and I will punish you. "

The building material of Nanjing Ming City Wall in Nandou is bluestone, while Beidou is city brick, also called official brick, so ordinary people can't buy, sell and use it at will.

Even at that time, Shen Wansan, who was rich, only donated to repair the city wall in Nandou, and the official bricks could not be used. The use of bluestone and official bricks clearly distinguishes Beidou and Nandou, and also clearly shows the pattern of Nanjing Ming City Wall to people.
