In the side hall of Xuanwu Hall, Yang Ji made a gesture of inviting tea to Yang Lun, picked up the tea cup, took a sip, closed his eyes and savored the taste, and said: "In hot weather, drink cold drinks, ice." Tea, although it feels cool at first, becomes unbearably hot afterwards. This is not the case with this tea. It can dissipate the heat from the body from the inside out and use heat to relieve the heat. It is amazing. Please, my brother."
Yang Lun took a sip of the tea without any condiments. He didn't know whether it was because Yang Ji had led him away or something else. As expected, he felt a special and refreshing fragrance. It’s really a unique experience.”
Yang Ji smiled and said, "I can only say that everyone has their own habits and preferences. I can drink the boiled tea that can satisfy my hunger, but I can't stand the mushy taste of vegetable soup. So it's a little simpler. At first I just felt refreshed and relieved, but now I’m really addicted.”
There was a small red clay stove next to the table with a tea pot on it. Yang Ji sifted another cup of tea for Yang Lun and asked with a smile, "When will you go to Yanzhou?"
"Leave tomorrow!" Yang Lun said with a bitter smile: "It's impossible not to go. Yanzhou governs eight states, and now all eight states are flooded. I don't know what the situation is there, and I am very worried."
"You should indeed go there early." Yang Ji nodded understandingly.
Yanzhou is located in the lower reaches of the Yellow River. The Grand Governor's Palace and the Grand Governor's Palace govern eight states. From west to east, they are Caozhou, Huazhou, Yunzhou, Weizhou, Jezhou, Beizhou, Dezhou, and Cangzhou. The first four states are located on the south bank of the Yellow River. The middle three states are located on the north bank of the Yellow River. The last Cangzhou is not only the mouth of the Yellow River, but also divided into two halves by the Yellow River.
It is precisely because of Yanzhou's unique division method that all eight states were affected by the flood. The three states in Hebei with higher terrain were slightly better off, while the four states in the south were quite miserable. Although Caozhou is not on the bank of the Yellow River, But after the surge of river water flooded Guanzhou in Yuzhou, it rushed down along the ancient path of the Yellow River.
Fortunately, Jishui diverts part of the Yellow River water to Juye Ze, and part to He Ze, and then flows southward from He River to Surabaya; and Bianshui River in Songzhou diverts part of the water to Surabaya, and from Si River to the Huaihe River. If these rivers had not played a huge role, Due to the flood diversion effect, the Huanghuai land south of Jishui cannot escape the fate of being flooded, and the yellowing area will also appear in advance in the Sui Dynasty.
Yang Lun, the new general manager of Yanzhou, not only has to restore people's livelihood, but also regulate the Yellow River, which can be said to be a heavy responsibility.
"The bitterness in my heart is just like this tea soup." Yang Lun picked up the tea cup and took another big sip, and asked: "The victims rioted yesterday, and they have only received good resettlement today. How was the situation when you came?"
Yang Ji put down the tea cup and sighed: "When I came, Yongzhou Prefecture had organized officials and assigned various families to provide disaster relief. The mood of the victims has been stabilized, and there will be no major chaos for the time being."
"Temporarily? Why do you say temporarily?" Yang Lun asked again.
Yang Ji pondered for a while and said: "In my memory, Jizhou and Youzhou in Hebei Province were hit by drought seven years ago and almost lost their harvest. It was the imperial court that used Liyangcang for relief, which enabled nearly ten million people to survive the disaster. Five Two years ago, it was Bingzhou's turn to suffer a severe drought, and three years ago, northern Yongzhou and Liangzhou experienced severe drought. Floods occur almost every year in the Huanghuai area. Anyway, my impression is that the disasters are getting worse year by year. Aggravated."
Yang Lun followed Yang Ji's words and thought about it for a while, then sighed: "Don't tell me that I haven't discovered it yet. The number of droughts and floods is really increasing every year. Why do you think so?"
Yang Ji said: "It seems that there is an alternation between the old and the new in the sky and the earth, and the collision of the old and the new creates abnormal weather. As for what it is and what it is called, I don't know."
Yang Lun sneered: "Is it possible that the world will also change dynasties?"
"It seems to be true. Changes in dynasties often make people miserable. But we are the people of heaven and earth. When heaven and earth change dynasties, we will naturally suffer."
"Absurd talk!"
"Let's not talk about it." Yang Ji himself couldn't explain a reason, and he didn't expect Yang Lun to believe it. He pondered for a long time and said: "When disasters occurred in the past, one state or one county could solve it on their own, and the victims hardly had to leave the state. There is a way to survive. But this time, the victims of the disasters in Yuzhou and Bingzhou came all the way to Guanzhong. This is a very incredible thing. Brother, have you ever thought about the problems involved?"
"It's really incredible." Yang Lun frowned and said, "It stands to reason that after paying taxes, people will still have a lot of surplus food on their hands. Even if a famine occurs, after the disaster is over, the victims can still plant some food on their own land. Other crops are used to resist disasters. Moreover, the people are very fond of home. As long as they still have the fields in their hands, they will not leave their hometown. But now they come all the way to Guanzhong, why? "
"First of all, large-scale land annexation occurred in the local area, turning these victims into landless tenant farmers. When the disaster occurred and the owners were unwilling to provide food relief, they had no choice but to seek help from the court; secondly, some people deliberately failed to act, Drive and trick the victims to come to Guanzhong to reduce their own burden. As for the land vacated after the victims leave, they can be allocated to their own people to win people's hearts." Yang Ji glanced at Yang Lun and continued: "I Today I asked the officials who counted the hometowns of the victims, and they said that among the more than 200,000 victims, 80% were from Bingzhou, and the number of victims from Yuzhou and Yanzhou was less than 20,000. Brother, you should understand now, right?"
"You mean to say that Yi Qian (Yang Liang's diminutive) is up to something?" Yang Lun suddenly realized that Yang Liang's disobedience of the court's orders was not a secret among the senior officials of the Sui Dynasty. It is obvious.
"I think so!" Yang Ji said calmly: "The seat of Yanzhou has been Huazhou, Henan since ancient times. However, your general office has been arranged to Weizhou, Hebei. This shows that you also have the intention of defending against the King of Han."
Xiangzhou in the west of Weizhou is connected to Luzhou under the jurisdiction of Bingzhou by Fukouxing. Fukouxing is a relatively long passage among the eight passes of Taihang. If Yang Liang marches from Luzhou to Hebei, he must pass through this road. Southwest of Weizhou is Weizhou under the jurisdiction of Yanzhou, where Liyangcang is located. The southern three of the eight Taihang counties are all in Weizhou. From north to south they are Baixing, Taihangxing, and Zhiguanxing. Their strategic position is even more important than Xiangzhou. .
If Weizhou and Weizhou were captured by Yang Liang, he would not only be able to contain the imperial army south of the Yellow River and intimidate the land of Henan, but he could also wipe out the loyal army in Hebei without any worries and secure the eastern parts of Bingzhou, Jizhou, Youzhou, and Yanzhou. Stay in control.
Yang Jian has now set up the Yanzhou Governor's Office in Weizhou, Hebei Province, obviously letting Yang Lun guard the South Sixing. Once Yang Liang rebels, he can quickly lead his army westward to block the Sixing.
However, Yang Lun was not a time traveler, and he did not know about Yang Liang's rebellion. How could he focus on these four war preparation routes in a peaceful and prosperous era? If Yang Liang were to surprise him, the consequences would be serious. That's why Yang Ji specially reminded Yang Lun.
Yang Lun was not an idiot. After Yang Ji's reminder and combined with Yang Liang's performance, he looked at the location of the Yanzhou General Manager's Office and immediately realized the seriousness of the problem. He nodded suddenly and said: "I will be more careful and send people to keep an eye on it." Death to Weizhou.”
"That's good." Yang Ji stopped and changed the topic: "Who are your assistant officers?"
"The chief historian is Yan Bi, and the Sima is Wei Jin." Yang Lun said with a smile: "Yan Bi is good at building construction and has great ability in water control; Wei Jin is the sixth son of Wei Xiaokuan, the Duke of Yun State, and has the ability to fight. No problem."
Yang Ji was silent for a while and then asked: "I also know Yan Bi's abilities. My uncle appointed him as the governor of Yan. He is obviously planning to let him help you manage the Yellow River. Do you have a plan to manage the Yellow River?"
"I have had some discussions with Yan Bi." Yang Lun sighed and said: "The only thing that can be used as a reference at present is Wang Jing's river management method of the Han Dynasty. Wang Jing was ordered to repair the Bian Canal. After many years of inspection, he discovered that the Yellow River The river course is unstable and changes its course frequently. This makes it difficult to control the water diversion of Bian Canal, and the water volume exceeds the capacity of Bian Canal, causing the danger of Bian Canal embankment bursting. So Wang Jing first built the Yellow River embankment from Xingyang Banzhu to the mouth of the sea, and then Then we started to manage Bianqu."
"According to historical data, after the Yellow River embankment was built by Wang Jing, there was no major diversion in the course of several years or hundreds of years, and there were not many overflows. But as you said, I seem to have encountered a world that is undergoing a change of dynasties, so in the Sui Dynasty, The Yellow River repeatedly broke its banks and overflowed its banks. The newly raised river banks were always washed away because they were not integrated with the old ones. Yan Bi and I thought like Wang If the scenery is like that, we need to conduct a thorough renovation of the river embankment."
"It will cost a lot to do this. Will uncle agree?" Yang Ji asked.
"Uncle said that money, food and manpower are not the problem, the key is that he has high requirements!"
"How high?"
"We are required to build a river embankment that will completely solve the flood problem in the Yellow River, instead of spending countless money and having another major embankment break in the coming year." Yang Lun said with a bitter smile: "What we have said over and over again is based on the experience of previous generations, and there is nothing new. And improvements, if this thing uses the entire river, I’m afraid it will be a waste of time and money in the end.”
Yang Ji thought for a while and then asked: "What is the situation of the Yellow River? What are the existing problems? You should know these, right?"
"Of course I know!" Yang Lun also did a lot of homework. When he saw a map hanging on the wall, he walked over. When Yang Ji came over, he pointed at the long Yellow River with a wooden stick and said: "The ancients based on the water flow of the Yellow River The water regime is divided into four sections: the upper reaches, the middle reaches, the upper middle reaches, and the lower reaches. The upstream refers to from the source to Shengzhou. This section has high mountains and steep slopes, large differences in the river bed, clear river water, and uniform flow, which are the most remarkable features of this section. Characteristics. The middle reaches refers to Shengzhou to Tongguan. This section runs from north to south and runs through the Qin-Jin Grand Canyon. Even if the water is strong, it will not affect the east and west banks."
"The middle and upper reaches are from Tongguan to Taohuayu in Xingyang, Guanzhou. This section of the river is fed by major tributaries such as Weishui, Fenshui, Luoshui, Qinshui, Danshui, and Sishui. It is characterized by water and sand, canyons and wide valleys. On the other hand, the mountains such as Zhongtiao Mountain, Wangwu Mountain, and Taihang Mountain on the north bank of the river are natural river embankments, which protect the north bank from floods; while on the south bank after passing the Xiaoshan Mountain, a large gap will appear, and this big gap is Shaanxi County, Yuzhou. Floods After being blocked by the mountains on the north bank, they violently attacked the Shaanxi County river embankment. Once this embankment is washed away, the Heluo Plain where Yuzhou is located will suffer."
"The downstream is from Xingyang Taohua Valley to the mouth of the sea. The water in this section of the river, which is more than 1,600 miles long, is gentle. In addition, the width of the river is different, so the sedimentation is serious, the river bed is rising all the time, and the river embankments It is intermittent and incomplete. If a certain embankment is built, the breach will be widened by fire. Even if it is blocked later, it will still be repaired on the original old embankment. In a few years, danger will appear again. This is what we must focus on management. section of the river."
After Yang Lun introduced him, he sighed and said: "The eight unfortunate states of Yanzhou happen to be located in the north and south of the lower reaches, so they were all affected this time. It's easy to restore people's livelihood, but my uncle asked me to manage the Yellow River, and also asked the Yellow River to stop poisoning both sides of the river. This is really hard. It’s so difficult for me. Sigh, I don’t even know what to do now.”
Yang Ji thought for a while and said, "I have some ideas that you may be able to learn from."
"tell me the story!"
"I'd better draw it for you!"
Based on Yang Ji's understanding of Yang Jian, since he was determined to build a new Yellow River embankment, he would definitely overcome all difficulties to build it in the end, so he sketched the Yellow River embankment he had seen in his previous life and used it as a three-dimensional The method was presented in front of Yang Lun, and then he drew a cross-section diagram.
He introduced it to Yang Lun in detail: "For a riverbed that is wide at the top and narrow at the bottom, I build a river embankment on both sides of the riverbed. This type of embankment has the effects of 'stretching the river to attack sand' and 'widening the river to consolidate the embankment'." "Shu River Sand Attacking" refers to the narrow lower part that serves to contain water, attack sand, and store water for navigation during low water seasons; while "wide river embankment embankment" refers to the wide upper part that prevents floods, diverts water, and fixes the river course in high water seasons. "
"Among them, 'Shu River Sand Attack' uses embankments on both sides to stabilize the river bed, tighten the river channel, increase the speed of water flow, increase the impact of the water flow, and prevent sediment in the river from being deposited in the river bed. As long as the sediment is washed away , then the rate of river bed uplift will be greatly reduced. The 'wide river embankment consolidation' corresponding to the 'shuhe sand attack' uses the wide area on the upper part of the two embankments to accommodate a large amount of water, thereby reducing the pressure caused by floods on the embankments. This prevents trapped floodwaters from breaking through the river banks, and at the same time, a wide area can be used to detain floodwaters and reduce the pressure on the downstream riverbed."
Yang Lun's eyes lit up and he said excitedly: "It makes sense, it makes sense..." He looked at the complete river and the countryside, then pointed at the strange and weird river embankments that were drawn separately, and asked: "These embankments What else is there to be famous for?"
"The river embankment I painted is composed of four parts." Yang Ji explained to Yang Lun one by one: "The low long embankment close to the river bed is called Ludi. The function of Ludi is to confine water, shrink the riverbed, and enhance the flushing of the river. The ability to sand the river in the dry season relies on it to "stretch the river and attack the sand". However, the low levee causes the river channel to narrow, and if it comes to the rainy season, the flood will overflow it; therefore, a moon similar to the river channel is built after the levee. Whenever the swollen river water exceeds the moon dike, the water will enter the moon dike and then continue to flow eastward. After the moon dike, there is a grid dike that is rammed into a tidal flat, and its function is to carry the water that overflows the moon dike; after the grid dike, there is The remote embankment that slopes downward further increases the flood storage capacity of the river and can accommodate floods exceeding the monthly embankment."
Yang Ji finally said: "Diverting the flood in this way will inevitably fix the flood in the river bed. But this kind of river embankment is thick and high. If these embankments were built on both sides of the lower reaches, it would be more than three thousand miles long. The distance, coupled with the fact that the tributaries merge into estuaries, wharves, ports and other facilities, require more engineering work. As a result, the amount of manpower, material and financial resources consumed will be an unimaginable astronomical figure."
"Then let's implement the work-for-relief method!" Yang Lun thought for a moment and said with a smile: "And you also said before that the more disaster years come, the more the court will carry out major projects; only when people have something to do, they will have money. Buy food and have food to eat, so you don’t gather people to rebel. Now Yanzhou has been hit by the disaster, the people have been displaced, and there is almost no way to make money. If I build this embankment in Yanzhou, the young and middle-aged victims of the disaster can just work in exchange for it. Money and food.”
"The truth is correct." Yang Ji smiled bitterly: "I'm worried that you will end up enriching officials and killing the people."
"Don't worry!" Yang Lun said solemnly: "During the construction process, I will build and supervise each section. If there is a problem or someone dies in any section, I will cause trouble for the officials in that section. At the same time, I will send Facao officials to supervise each section. In addition, please ask the Yushitai to supervise the Yanzhou Facao officials."
"It is best to set up a reporting point in each river section and send trustworthy people to sit there for people to complain." Yang Ji nodded and reminded: "Before you start construction, you must let the people know how much the wages will be and how much they will work every day." How long does it take? If people don't get their due wages, encourage them to go to the reporting point to complain. Such layered supervision can reduce corruption incidents."
Yang Lun put down the wooden pole, carefully put the drawings away, and said to Yang Ji: "I will take it to discuss with Yan Pi to see how to repair it and how high and thick it is."
"If this embankment is built for thousands of miles, it will be a huge project that consumes countless manpower, material and financial resources. There is no room for your sloppiness. You must find more officials and craftsmen who are proficient in water control to discuss it. Don't get bored. Just do it." At this point, Yang Ji reminded him uneasily: "None of us know how to be craftsmen or architects, and what I drew was just a sketch. I don't know whether it is reasonable or not, so when it came to the actual construction, I didn't know how to do it. It depends on skilled craftsmen. Brother, please don’t let the self-righteous layman command the expert. If you give blind orders and mess up, this project that benefits the country and the people will most likely become a project that will be infamy for thousands of years.”
"I understand." Yang Lun nodded solemnly, cupped his hands and said, "Vajra slave, time has not waited for us, we brothers say goodbye."
"Brother, take care of me!" Yang Ji bowed to the ground.
Yang Lun helped Yang Ji up with both hands and patted him heavily on the shoulder, "The situation in Liangzhou is countless times more complicated than that in Yanzhou. Your responsibility is heavier than mine, so you must also cherish it."
