After Guo Duanduo completed the established peace conference tasks in Jinling and Donghu one after another, he rushed to Shouchun in early December, and temporarily stayed in Shouchun to coordinate the transfer of reinforcements.

Although the other bank of Shouchun is Yingzhou controlled by Xu Mingzhen, the Shaying River (Yingshui), which leads to Xuzhou and the northern part of Ruzhou, and leads to Xingzhou through the tributary Jialu River (chasm), and connects with the Yellow River, enters Huaikou in Yingzhou on the other side of Shouchun.

With six or seven million catties of grain and other materials per month, waterway shipping is always the most trouble-saving and labor-saving.

Otherwise, it is necessary to requisition tens of thousands of people, tens of thousands of mules and horses, and the corresponding carts to travel from south to north, and a large number of people must be requisitioned to ensure that the post roads and gallops along the way are smooth, which will cost the people and money.

The reinforcements provided by Tangyi were extremely important for the Hehuai coalition forces to fight on the western flank at this time, and also involved the transit from the two states of Qianying.

In addition, Liang Chu concluded a peace agreement that some of the Liang army in Guanzhong would return from Liangzhou on the merchant ships of the Chishan Society, and Shouchun was also the designated transit point.

Guo Duanduo, as a ministerial-level official of the Liang State, naturally wanted to stay in Shouchun to supervise everything at such a difficult time, so as not to go wrong.

On the Tangyi side, Tian Cheng, who also led the Shouzhou Thorn History, and Wang Zhe, who were in charge of the affairs of the Central Plains, Heshuo and other northern regions, were mainly handed over to Guo Duanduo.

Since the Qin and Han dynasties, Shouchun has a very important strategic position and military value, located in the pivotal point of water and land transportation, and is conducive to the natural ring of defense, and the water and soil are fertile, the products are abundant, and it has always been the core of the contention of all parties in the Central Plains when the chaos was great.

After the large-scale excavation of the Grand Canal on the eastern route in the previous dynasty, and the serious siltation of the Yuxi River (wet water) and Anfeng Canal leading from Chaohu Lake to the Yangtze River, the strategic position of Shouchun and Huaixi was slightly reduced.

If you look at it from the perspective of the entire Jianghuai and Hehuai land, the core of water transportation between the Hehuai and the Jianghuai is still the eastern waterway dominated by Hangou (Shanyangdu), but from the perspective of Tangyi or Huaixi, the waterway that communicates the Jianghuai River from the Yuxi River through Chaohu Lake and the Huishui River can be said to be the lifeline of Huaixi.

After the restoration of the Anfeng Canal at the beginning of the year, the continuous dredging of the Anfeng Canal and the more than 200 miles of waterway connecting the Chaohu Lake with the Weishui River has not stopped, but as a regular work, it has been decomposed into the counties and townships along the coast to continue to carry out.

Han Qian wants to further build the Yuxi River, Chaohu Lake, and Weishui River into the core waterways connecting the Jianghuai River, so that the East Lake can surpass Yangzhou in a strategic geographical location.

As the northern mouth of this core waterway, the importance of Shouchun on the territory of Tangyi in the future is needless to say.

Of course, before that, Shouchun was the seat of Emperor Tianyou when he served as the envoy of Huainan Jiedu in his early years, and then it was always the place where Xu Mingzhen served as the envoy of Shouzhou Jiedu and the government office.

Shouchun city is majestic, the outer city is Guocheng or Luocheng, the circumference is thirteen miles, and the city wall is rammed earth.

When the Shouzhou army withdrew, nearly 60,000 people lived in Guocheng, cultivating nearly 400,000 acres of fields inside and outside Guocheng.

The inner city is the sub-city or called the golden city, in Thursday, the city wall is covered with bricks and stones, high and steep, and there is a deep hao outside the city wall, which can be described as impregnable.

Shouchun City leans on Bagong Mountain in the north, and the Beiqishui River goes around the city from the east, and there are many channels to lead water into Guocheng for irrigation and living in Guocheng; There were also six fortified fortifications built inside and outside the city.

More than 20 miles to the north of Shouchun City, on the remaining vein of the northern foot of Bagong Mountain, it is the danger of the shape of the middle reaches of the Huai River, and the Kip Stone Mountain (Kip Shikou) known as the first gorge of the Huai River.

The Huai River goes from west to east, and after reaching the west foot of Bagong Mountain, it is blocked by the mountain, turns to the northwest, and continues to flow eastward through Kip Shi Mountain.

The Huai River is mighty and mighty, and the narrowest part of the river section flowing through this Kip Shikou is only 70 zhang wide at the narrowest point of the cliff stone shrinkage on both banks, so that in summer and autumn, the upper reaches of the Huai River are flooded every year, and the narrow Kip Shikou can not be discharged in time, and a large area of flood detention zone is often formed in the upper reaches of the Kip Shikou area, which infringes on agricultural production very fiercely.

Xu Mingzhen built two fortified camp cities on each side of Kip Shi Mountain, and at the same time built another camp city on the gentle slope of the Huai River at the western foot of Bagong Mountain to protect the pass between Dong Kip Shi and Shouchun and prevent the enemy from forcibly crossing the Huai River from the opposite bank; Fengtai City is located only 123 miles east of Kipshikou.

Such a dense group of fortresses—most of which have survived for thousands of years, and Emperor Tianyou and Xu Mingzhen have only repaired and strengthened the ruins or ruins—plus the special geographical location and topography of Kip Shikou, Bagong Mountain, Huai River, and the Huangshui River and Wabudang in the northeast of the city, constitute a unique and easy to defend and difficult to attack tight defense system in Shouchun.

For more than 30 years, the Liang army crossed the river from Huaixi to the south many times, and there was no time to successfully tear through such a complete defense system in Shouchun.

If Xu Mingzhen did not take the initiative to withdraw from Shouchun City this time, Han Qian could only capture Huoqiu and Fengtai first, and then occupy Bagong Mountain, cut off the communication between Shouchun City and Kipshikou, and then besiege the soldiers and civilians in the city.

Otherwise, if they really want to attack Shouchun City directly, the Tangyi army doesn't know how many casualties they will have to pay.

The streets and alleys of the inner and outer cities of Shouchun are vertical and horizontal, the houses are neat, and there are many shops along the street, which are also dazzling. There are also dozens of large and small workshops in Guocheng.

Shouchun has long been the economic, political, military, and cultural center of Huaixi.

At present, in addition to stationing more than 8,000 horse infantry troops and sailors in Shouchun, Han Qian also transferred thousands of engineers, craftsmen and families to Shouchun to restore the production of Shouchun's craftsman workshop based on armor and weapons, and also determined that a fourth comprehensive school will be established in Shouchun in addition to Qianyang, Chenzhong and Donghu after the year.

In addition to the assassin Tian Cheng, Governor Shi, Sima, Zhu Cao joined the army, and the Shouchun County Commander were all capable officials personally selected by Han Qian - considering that Xu Mingzhen was not so honest, Wang Zhe temporarily settled in Shouchun, and a long-term job to do was to find out how many of the 60,000 people in Shouchun were secretly sent by Xu Mingzhen to lurk.

After the East Lake embankment, a new large-scale water conservancy project, Longchi Mountain Weir Lake, will also start at the northern foot of Longchi Mountain in the southwest of Shouchun City after the year.

The southwest of Shouchun City, that is, the Longchi Mountain area located in the west of the Beishui River and the junction of the western part of Shouzhou and Huozhou, is the remaining vein of Huaiyang Mountain.

There the peaks and mountains crisscross and crisscross, especially the east, south and west sides of the terrain are higher, and the north side is low-lying, inclined to the Huai River, every summer and autumn rainy season, flash floods, the Huaibin area forms a serious flood disaster, roads, houses, fields are washed away.

When the rainy season passes, or the rainy season is not strong, it will be because the Beiqishui River and the stream from the source of the Huaiyang Mountain are blocked by Longchi Mountain and other stretching peaks, irrigation cannot be there, and there are frequent droughts.

Huaixi is thousands of miles of fertile wilderness, only this area is located between Shouhuo, even in the Chengping era are extremely poor, the post road and Chi Road on the south bank of the Huai River are also built in this area.

The Department plans to build a weir embankment in the low-lying area at the northern foot of Longchi Mountain, and collect the streams and canals of the upper peaks into a large lake artificially blocked in front of the weir embankment, so as to regulate the water consumption in the north in the dry and rainy seasons, so that hundreds of thousands of acres of fields can be reclaimed and irrigated, and the frequent floods and droughts in the local area can be effectively controlled

It will also ensure the cultivation and bumper yield of the existing farmland in the west wing of Shouchun City.

Of course, this is also the first step of Han Qian's plan to govern Shouzhou on a large scale, and the problem of flood detention of the Huai River through Kip Shikou has been left from the ancient Yu water control period - legend has it that Kip Shikou is split by Dayu with an axe.

This is not without a solution, in the south side of the Bagong Mountain excavation of the flood channel, the water from the upper reaches of the Huai River into the lower reaches of the Bei Weishui River Wabudang, and then from the Wabu Dang into the downstream Huai River waterway.

It's just that to form a sufficient scale of flood distribution, this section of the flood distribution canal is expected to be about fifty or sixty miles, and the amount of excavation work is too huge according to the current standards, and Han Qian will not think about this problem for the time being, preferring to continue to strengthen the embankment on the foundation of the south embankment built by Xu Mingzhen in his early years, and dump the stranded flood water into Yingzhou on the north bank.

Xu Mingzhen can't say that he is poisonous, and the Changhuai South Dike was built by Xu Mingzhen after he was appointed as the envoy of Shouzhou Jiedu, unless the flood problem on the north and south banks should be considered as a whole in the future, and then the excavation of flood channels should be considered.

After recovering Shouchun, Huoqiu, and Fengtai, Tangyi did not add new counties in the buffer open area with the Shouzhou army, but opened more than 20 camps of displaced people according to local conditions, and received more than 70,000 old and weak women and children who fled from the north bank - most of Ding Zhuang were forcibly requisitioned by the Hehuai Liang army or the Shouzhou army along the way - concentrated on ensuring food and lodging and the most basic medical aid.

Among them, there are nine large camps of displaced people set up around Longchi Mountain, taking in nearly 40,000 displaced people, which is convenient for the construction of Longchi Mountain Weir Lake, and can recruit enough labor on the spot.

In terms of the organization of the grassroots poor, Tangyi has long been perfect.

Each camp of displaced people sent only a dozen or so staff, including directors, doctors, engineers, teachers, secretaries, and assistants selected from the Liyang School, and managed a large camp with a capacity of three or four thousand people, mainly for the elderly, weak, women and children, in an orderly manner.

In addition to building a fixed walled house nearby and renovating the living environment, a very small number of young and strong men, young and middle-aged women with the highest proportion and teenagers over 14 years old will be organized to carry out some basic drills and training, so as to prepare for the start of construction of Longchi Mountain Yanhu Lake after the year.

Compared with the escape from famine and famine, the material supply of the camp of the displaced people is still quite sufficient, and the main labor force will initially ensure the ration of one and a half catties of brown rice rations one day - if you really go up to the embankment to carry out high-intensity labor, the standard will be raised, and the old and weak and children will be guaranteed with one pound of rations per day, and they will improve their food by catching fish according to local conditions as much as possible, and will provide some necessary oil; Elementary schools have also been set up in the camps for literacy calculus for teenagers between the ages of 10 and 14.

Except for the camp for displaced people near Longchi Mountain, the setting up of other camp for displaced people is combined with the construction of large and medium-sized water conservancy facilities to be started in the local area.

The technical work of cash-for-work has long been played by Tangyi.

Guo Duanduo was over forty years old, and his father was a guest of Liang Taizu's staff.

At the age of eighteen, Zhu Yu led more than 100 subordinates to lead the Luozhou Thorn History, and Guo Duanduo was among them.

At that time, Heluo was devastated by the repeated bloody wars for many years, and all the counties were broken, when Zhu Wen was crowned the king of Liang, the Heluo area was less than 10,000 households, and it was Zhu Yu who recruited displaced people to divide into 18 counties, and in just three years, more than 300,000 households were enriched, and nearly 20,000 hectares of land were restored.

At that time, Guo Duanduo felt that Taizu did not pass on the throne to His Majesty, and it was really unreasonable.

He stayed in Shouchun for more than ten days, and before passing through Huaixi, even if he was more inclined to His Majesty in his heart, he also deeply felt the greatness of the world, and it was not that there were no people who were bright with His Majesty.
