The East China Sea is mostly Pingchuan Lake, and only the west side of the tomb is close to Baishi and there is a low hill.

In the territory of Wanling Mansion in the northwest of Donghai County, there is a big lake called Ze Lake, with a circumference of about 800 li, and the Huai River runs through it to make it open to the sea. Wanling Mansion Wuyi and a military town are all located between Zehu Lake and Huaishui waters. The northwest of Zehu Lake is Zedangyi, the southwest is Xinfengyi, the southeast is Qichuanyi, the east side is Wanlingyi, where Wanling Mansion is located, Wanling is Yuza military town to the east along the Huaishui, and then the east near the sea is Pingyi, also known as Pingcheng. Pingyi produces fine wine, its name is "Pingcheng Autumn Dew", the surname is Lie, ranking first in the world.

Shangnan Town is a market town without city walls, connecting Gucheng Mansion of Jinyang County, Nanyang Mansion of Yongning County, Henan Mansion of Fenyang County, it is the place where the three counties are accessible, the Guanghan Canal of Jinyang County and the Danjiang River meet in Shangnan Town, it is the northwest entrance of the Nanyang Basin of Yongning, and the southern Henan Mansion of Fen County is the border of Henan Prefecture through the Funiu Mountain Pass to the north. Four hundred years ago, the Yuan clan of the old dynasty built a middle city here and took a valley more than 50 miles southeast of Shangnan, which was really a mistake. Four hundred years ago, Nanyang was the hinterland of the Yuan clan, and the construction of the city was more about feng shui, and there was a lack of consideration for economic and military use. After the rise of the Fu family in Nanyang Mansion in Yongning County, they considered building a city in Shangnan, but under the pressure of the Huo family in Jinyang and the Xun family in Fen County, they had to give up. Shangnan does not have high walls and deep gates, but three horizontal, three vertical and six long streets are six miles long, making it seem to have the momentum of the first important town in the old Chu.

Qingjiang Mansion is located in the southwest of Yue County, known as Yuetou Jingwei in ancient times, the gate of Fujian, the Wuling Mountains of 600 miles in the south, the Huaiyu Mountains in the west and Jing County are separated, and the topography of Qingjiang Mansion is poured from south to north. The Qingjiang River originates in Yunling, flows through the valley and hilly belt between Wuling Mountain and Huaiyu Mountain and enters the territory of Qingjiang, and several water flows originating from Wuling Mountain such as Lishui flow into Qingjiang, which makes the flow of Qingjiang increase suddenly, which is conducive to the navigation of giant ships. Xuancheng is located in the southwest of Qingjiang Mansion, backed by Wuling Mountain and Huaiyu Mountain, and Lishui joins the Qingjiang River close to the south wall of Xuancheng.

The distribution of mountains and rivers in Qingjiang Prefecture is intricate, forming a series of small bead-shaped basins, the topography of these basins is relatively closed, becoming a small area with relative reading power, connected by a series of rivers and ditches such as Qingjiang River and Lishui, which is very easy to form some important military towns and important passes, which is also the root of the bandits' entrenchment. It is rare that they are all facing east and north, which is conducive to going out and not conducive to attacking. In the southeast and southwest of Qingjiang Prefecture, there are high Yunling, Wuling Mountain, Huaiyu Mountain and the outside world, and there are Qingjiang, Lishui, Shouchang River and other river sources flowing through Yunling, Wuling Mountain, Huaiyu Mountain and other river valley lowlands as a traffic channel through the mountains, which can communicate with Jingjun, Nanmin and Nanning.

Lishui and Qianjiang all originate from the middle mountains of Wuling Mountain, Qianjiang River enters the sea to the east, absorbs many tributary water systems along the way, converges into the sixth water flow in the world, the amount of Lishui is much smaller, when the west flows into the Qingjiang River, the mouth of the river is not more than 300 steps wide, and the depth is not more than six or seven zhang. Lishui and Qingjiang River valley low place circle dozens of miles, is the largest of more than 100 hilly basins in the south of Yue County, there are towering and upright Huaiyu Mountains in the west, Wuling Mountains filled with miasma in the south, Taishan Mountain Range, a branch of Wuling Mountains in the east, and endless low hilly belt in the north. If you have enough strength to occupy the surrounding mountains and dangerous land, you can get millions of acres of fertile land, plus tea plantations and mulberry gardens on the hills, this river valley alone can support hundreds of thousands of people.

The following is a detailed description of the topography of the Lishui River Valley: Lishui River Valley, with Taishan Mountain on the east side, Wuling Mountain on the south side, Huaiyu Mountain on the west side, and hilly belt on the north side; The Qingjiang River passes through the Lishui River Valley from south to north, and the Lishui River flows into the Qingjiang River from east to west, and the Lishui River and the Qingjiang River divide the Lishui River Valley into three parts: the south bank, the north bank, and the west bank; At the beginning of Xu Ruyu's entry into the Lishui River Valley, the Qingyan Army occupied the south bank, Xiangfan would occupy the north bank, and the west bank would continue to be deserted; Xuancheng City, the seat of Xuanchengyi, was built on the north bank near the mouth of the Lishui River, and the circumference of the whole city was eight miles, which was not large; The west side of Taishan is the Lishui River Valley (Xuanchengyi), the east side is Fuzhou Yi, Taishan is connected with Wuling Mountain, in the place close to Wuling Mountain, there is a big passage, there are four villages along this passage, that is, the four villages of Taishan. The section of the passage close to Xuancheng is Lishui, Yuanqiao Village is on the north bank of Lishui, and Shengyun Village is on the south bank of Lishui, but both villages are in Taishan; Lishui enters the middle side of Taishan and traces back to Wuling Mountain in the south, and passes through Shaozhai before Lishui enters Wuling Mountain. There is a long and narrow canyon to the east of Shaozhai, this canyon is the eastern half of the passage between Fuzhou and Xuancheng, and Jizhai is at the other end of the canyon, which actually belongs to the boundary of Fuzhou; On the south bank, along the Lishui River, Xu Ruyu built three forts and one city, close to Taishan is Gaotang Fort, down is Jiuqu Fort, Kaiyang Fort. On the south bank near the mouth of the Lishui River, Lishui City was built. Lishui City and Xuancheng are opposite each other, and they are only four or five miles away; Xiangfan will build two dock fort groups on the north bank, distributed on the inner side of the hilly zone, Beilingbao is close to the Qingjiang River, Ulunbao is fifty or sixty miles away from the Qingjiang River, close to Taiwan, the Ulun River originates in the hills near Ulunburg, almost parallel to the Qingjiang River, but the flow direction is to the south into the Lishui, the night battle of Ulun River is on the west bank of the Ulun River; There are several cottages of the rogue forces at the western foot of Taishan, among which Yuantun and Gaotang are more famous. Gaotang Village is in the north of Yuanqiao Village, Gaotang Creek originates there, Gaotang Creek flows into Lishui to the southwest, the mouth of the stream is Gaotang Fort built by Xu Ruyu, and Yuantun is further north; In the middle hilly belt north of Beiling Fort and Ulunburg, there are 12 Liukou cottages, called the Twelve Kou League, among which Tiankui Village and Dark Village are more famous; Tiankui Village is directly north of Beiling Fort, adjacent to the Qingjiang River. The village is in the middle of the hilly belt, close to Ulenburg, and the battle of the village took place near the village; In the land on the west bank, the Hongjiang River originates from Huaiyu Mountain, flows from northwest to northeast, until it merges into the Qingjiang River, the confluence point is some north of Tiankui Village, and the water village forces on the Qingjiang River are sealed in the Hongjiang River by the Qingjiang Water Camp in the later period; In the land on the west bank, the Hongjiang River originates from Huaiyu Mountain, flows from the northwest to the northeast, until it joins the Qingjiang River, the confluence point is in the north of Tiankui Village, and the water village forces on the Qingjiang River are sealed in the Hongjiang River by the Qingjiang Water Camp in the later period. That's it.

The river flows into the sea in Yanling, and the river is vast and more than ten miles wide.

There are two large sandbanks not far from the east side of Yeonryung-eup, one Dongbuzhou and one Hudouzhou, both of which are large sandbanks that are hundreds of miles around, and have been on land for hundreds of years, and were originally the places of the old Chaolius. Both sandbanks were formed by river floods, and the land was fertile, and the families of the East China Sea gradually moved to the sandbanks and reclaimed wasteland to set up salt farms. The Puji bandits arose in the new dynasty, and most of the inhabitants on the two sandbanks were taken captive by the Puji bandits, and the two sandbanks were abandoned.

Xu Xing drove the Puji bandits out of the East China Sea, but the two sandbanks were left on land, and the family had no intention of risking their business and left them to waste.

The ocean between Hudouzhou and Yeonling-eup is only 20 miles away, and the five islands connected at the base in the middle are lifted out of the water for nearly 30 zhang, and it looks beautiful and tall in Donghai County, which is thousands of miles flat.

Xu Xing was the East China Sea to reject the help of bandits, and had established a military base on five peak islands, so it was named the military mountain.

In the early days of Xu Ruyu's county restructuring in Yongyang, Hailing County was established with Dongbuzhou as the main body and Jinghai County was established on Hudouzhou.

The four counties of Yanling, Qingpu, Jinghai and Hailing set up a defense area, which will also be the Yanling Mansion in the future.

The Longyou city in the northwest of Yongyang was temporarily under the jurisdiction of the Chen clan, and Xu Ruyu set up Guangling County between Longyou and Yongyang.

There are only four prefectures in Southern Fujian, the Ryukyu and Penghu Islands are Fengzhu Prefecture, the northern part is Zhangzhou Prefecture, Quanzhou Prefecture is located in the southeast, and Putian Prefecture is located in the southwest.

The Tea Horse Trade Road, all the way through the Qingjiang River into the Yunling Mountains, all the way along the Lishui into the Wuling Mountain.

Lishui originates from Cuishi Ridge, after Cuishi Ridge is a hundred miles of Qingfeng Long Gorge, through Qingfeng Gorge zigzag to the southeast, out of Wuling Mountain is Wulingyi, Zhangzhou capital of Nanmin County.

Wulingyi is next to the southern foot of Wuling Mountain, the Southern Fujian family will block Baiyi in Wuling Mountain, and there are many disputes with Baiyi in Wulingyi, for decades, plus Wulingyi is more hilly and less flat, so the population is scarce, and the power of the family is not strong.

To the east of Wulingyi is Zhangtaiyi, Zhangtai Binhai, Puji bandits invade there from time to time, where ten households and nine emptiness, people's livelihood withered, not much better than the early Qingjiang Mansion.

Longyanyi is located in the southeast of Wulingyi, which is close to Quanzhou Prefecture and is an important town in northern Southern Fujian, where the Zongzheng family stationed heavy troops.
