Zhao Long's unintentional interjection was about to the point, and Han Gang was reminded by him, and his spirit suddenly shook: "If you go outside, you must first settle inside!" If there are too many constraints behind you, how can you achieve success? Open the market, the market is easy, not unbeautiful. Only the officials and families of Qinzhou have many things to change back, if the market suddenly prospers, and the people and wealth are cut off, they will provoke the anger of the public. When the bullets are added to the top, who can open up the river with peace of mind? ”

Han Gang was talking about Wang Hou's heart knot, his eyebrows were slightly furrowed, and he was a little helpless. Looking at Han Gang, he got up and asked humbly, "So you want Tuntian first?" ”

"Compared with the city of Yi, Tuntian is not difficult, Qinzhou along the border is sparsely populated, as long as you see the seams, build a fort and defend the reclamation, there will be a small success in two or three years. Through the Tuntian soldiers to deter the surrounding Tibetan tribes, crack down on the rebellious generation, and then fairly deal with the disputes between the Tibetan and Han families, and give the chiefs of the Han family to official positions to win people's hearts. that it may be used by me, and not by the Western Xia. In the future, they will also help to attack the Western Thieves! ”

The method of stabilizing the frontier mentioned by Han Gang has been inherited from ancient times to the present, and it is not an original opinion. But Wang Hou was already moved by Han Gang's previous words, and he couldn't stop nodding, only feeling that Han Xiucai in front of him was really knowledgeable and knowledgeable.

Han Gang no longer said anything about the ease of Tuntian City, he said everything he could say, and if he continued to talk deeply, he would reveal his bottom, and he turned his head and sighed softly: "However, Kansai has long been a resort, and the production is far less than that of the Han and Tang Dynasties, otherwise there is no need to go to Tuntian with hard work." Many of the best fields were washed away by the flowing water of the Yellow River, and the Yellow River turned yellow as a result. That's not a good thing! Not only was the good land in Guanzhong lost, but even the world suffered. ”

Han Gang said solemnly, and Wang Hou leaned forward and listened attentively.

"Like the Yellow River, a bowl of water, half a bowl of sand, and sand all come from Guanzhong. If it is before Tongguan, the Yellow River is turbulent, and the sediment flows with the water, but after leaving Tongguan, the river water slows down, and the sediment carried in it will be deposited. Han Gang raised the wine bowl to Wang Hou, in the turbid wine that had not been sifted, many wine lees were floating and sinking with the shaking of the wine bowl, and the 'Green Ant New Brew Wine' said that it was this kind of unfiltered wine pulp, "I heard that the Bianhe River is the Yellow River and the sediment is silted, and the river must be cleaned up every year, but even so, it can't catch up with the speed of the river bottom rising." ”

Wang Hou nodded yes, he had been to Bianliang, Tokyo, and also knew that the road was near the mouth of the Bianhe River connecting the Yellow River, and the boats in the embankment were even higher than the roofs outside the embankment, all because of the sediment backflow of the Yellow River. The people on both sides of the Bianhe River are suffering unspeakably.

Han Gang put down the wine bowl, and the turbid wine in the bowl gradually settled, and the sake lees sank to the bottom of the bowl: "You see, as long as the water flow is gentle, the sand in the water will naturally settle down. If you want to control the water of the Yellow River, you must first control the sand of the Yellow River. If you want to control the sand of the Yellow River, you must first start from the source of sand. Otherwise, if you pile up the embankment and dig deep into the bottom of the river, it will only be an emergency measure to cure the symptoms but not the root cause, and it will be a matter of time before the embankment breaks and is rerouted. ”

"What Brother Han said is exactly right." Hearing what Han Gang said clearly, Wang Hou unconsciously took a sip of the tasteless turbid wine, and sighed, "In June of the eighth year of Qingli [1048], the Yellow River broke in Shanghu [now Puyang County] in Lanzhou, and flowed north to the Bohai Sea. In order to fill the breach or divert the river to the north, the ministers of the court did not know for several years, and then reluctantly acted and did not succeed.

In the fifth year of Jiayou [1060 AD], the sixth silica of Wei County, the Daimyo Prefecture, broke the embankment, separated a tributary, and entered the sea from the Duma River to the east. The Yellow River flows into the sea at the same time as the original northward flow through the east, and is called the Ergu River. The Yellow River is divided into two, whether it is blocked or sparse, or let it flow, from the Renzong Dynasty to the present. The rich, Korean, and literary ministers have argued in the court.

And Liangshanbo! Where does the 800-mile water surface come from? It was not the first year of the Later Jin Dynasty [944 AD] that the Yellow River broke in Huazhou, flooding Cao, Shan, Pu, and Yun prefectures, and the flood was accumulated in Juye, and Juyeze became Liangshanbo. ”

"I heard that a few months ago, the Yellow River seemed to be diverted again?" Zhao Long interjected and asked.

"That's right. In August, the Beiliu failed to fill the river, and the Xujiagang River burst. The five military states of Shuipan Daimyo, En, De, Cang, and Yongjing. Tens of thousands of soldiers and civilians drowned. Wang Houchang sighed, "For this river, I don't know how much money it spent, and I don't know how many people died, but it can't be cured after all." ”

Han Gang lowered his head and took a sip of wine. Just looking at Wang Hou's discussion, he definitely worked the river defense. Han Gang knew that in terms of details such as the water conservancy of the Yellow River, he was definitely inferior to Wang Hou, who had studied deeply. Unable to go into more detail, Han Gang brought the topic back to soil erosion, which he is good at: "This is the harm of too much sediment, the rain in the south is ten times that of the north, and the water potential of the Yangtze River is far greater than that of the Yellow River, why does the Yangtze River rarely break its banks?" It's not because there is less sand in the Yangtze River and more sand in the Yellow River. Too many trees were cut down, and there was no grass and trees on the mountain, and when the rain came, the mud and sand would fall. Look at the clarity of Jingshui, and then compare the turbidity of Weishui, why is there a clear distinction between Jingshui and Weishui? ”

"There are many trees in Jingyuan, which can solidify the soil, and the Wei River is full of light mountains from Fuqiang upwards." Wang Sunchen replied quickly, Han Gang said in simple terms, he could also understand and think thoroughly.

"Well said!" Wang Hou raised his hand and saluted Wang Sunchen with a bowl of wine. Wang Sunchen smiled and took the drink very freely.

"Although General Wang Jun is young, he has traveled a lot in Kansai, and he knows a lot about the geography of various places! The martial arts are also outstanding, and the bead archery is a must. Han Gang patted Wang Sunchen on the shoulder and introduced it to Wang Hou, and a few words made Wang Sunchen grateful.

The more the three people in the room listened, the more fascinated they became, and few people could explain the Yellow River flood from the root cause so clearly. Han Gang said on a whim, swept away the clutter on the table, dipped his fingers in the wine, and drew on the light table. First, I drew a 'several' shape with the tail dragged up. Han Gang pointed and said, "This is the Yellow River!" ”

What is really useful through the millennium? It is the understanding of the geography of the country! - At least for Han Gang now, it is.

An atlas that is only worth a dozen yuan after a thousand years, put it a thousand years ago, don't say a thousand gold, ten thousand gold can also be exchanged. It was a map drawn by millions of people and various advanced instruments, and it was not comparable to leisure.

Han Gang's history is not good, and he is ignorant of the details of future historical development, but his understanding of geography is very good. Coupled with his eloquence, even if the understanding of the place name has been deviated for thousands of years, it is easy and effortless to fool Wang Hou, a hairy boy.

Just this stroke of 'several' has already made Wang Hou admire Han Gang even more. If you haven't read a lot of geoscience books and carefully deduced the geography of rivers and mountains, how many people in this world know the direction of the great rivers and the Yellow River? On the "Water Scripture Note" that has been circulated in the world, there is never a page of the world's map. Wang Houneng learned the general direction of the Yellow River and the Yangtze River, or was stained with the light of his father Wang Shao, and from Cai Ting, the envoy of Weizhou Zhizhou and Jingyuan Road, he saw the map of the world copied from the Chongzheng Palace.

"What does the Yellow River look like?" Wang Sunchen and Zhao Long also looked at the table curiously, although they had both seen the Yellow River, they also drank the water of the Yellow River tributaries every day. But let them say one, two, three, the Yellow River is definitely a black eye, and I may not be able to burst out a word for a long time.

"That's right! Exactly! Wang Hou helped Han Gang prove that he nodded a little at the bottom right of the word 'several', "This is Tokyo." ”

"This is Tokyo......" Wang Sunsin and Zhao Long nodded intently, but they didn't know if they understood.

Over the millennium, many of the specific geographical terms have changed. Han Gang may not be as good as Wang Hou in terms of place names, but Han Gang in the large area is familiar with each other after confirming each other with the memory of his predecessor. He pointed to the empty space on the right side of the word 'several', "This is Hedong [now Shanxi]. Because it is located on the east side of the Yellow River, it has the name of Hedong! ”

The finger pushed up from the east of the river again, stopping at a horizontal place on the head of the word 'several', Wang Hou immediately said: "It's the Xijing Road of the Khitan." ”

Han Gang dipped some more wine, dragged it horizontally, and almost sealed the opening under the word 'several', "This is Weishui." And we're in ...... right now."

After a light pause, Wang Hou wisely nodded under the horizontal on behalf of the Wei River, and said in a deep voice: "Fuqiang City." ”

"And the thief is here." Han Gang pointed to a piece of land surrounded by the Wei River and the Yellow River, "This piece of land, surrounded by the Yellow River on three sides, is shaped like a cloth cover. That's why I call it the Loop! ”

"Hetao!?" Wang Hou repeated. He muttered a few times in his mouth, as if chewing on the meaning of the word. He nodded heavily after the last, "Good up, good up, it does look like a pocket, it's exactly what a sleeve looks like." ”

Han Gang straightened his waist, opened his arms exaggeratedly, and said loudly: "The Yellow River is harmful, and it is only profitable. The party members occupy this place, and the water network in Xingling [Note 1] is intertwined, as if it is plugged into the south of the Yangtze River, whether it is farming or grazing, it is far superior to other lands. In addition to Xingling, there is the Hanhai Sea, which makes it difficult for foreign enemies to invade, and this natural danger is especially the Yangtze River, which is as wide as the abyssal sea. If you want to go straight to the nest of the Westerners, you must first consider how to cross the 700-mile Hanhai Sea, and also consider how to ensure that the grain route is unblocked, otherwise there is a danger of annihilation. ”

Wang Houkou said, "If you attack the western thieves from Hedong, Yanyan, and Huanqing, you will definitely be blocked by Hanhai. If you attack from Qinfeng and Jingyuan to the north, there are Tiandu Mountain and Douling to block it. Even if all roads attack at the same time, as long as they rely on natural danger, the western thieves can defend their forces when they disperse their forces. But if it is on the westerly side, such as Lanzhou, a surprise soldier can be put on it, but it can make the western thief unbearable. ”

"Lanzhou? Is that the possession of the thief? Zhao Long asked.

Note 1: Xingqing Mansion, Lingzhou, that is, the current Yinchuan, Wuzhong.
