After listening to Pei Yuanjin's words, Emperor Han thought that he was also afraid of offending people, so he said it so tactfully, so he also had an idea in his heart, "Since this is the case, announce that the two of them will go to the palace first and then make a decision!" ”

Suddenly, Yao Qian and Gao Han entered the hall one after the other to salute.

At first sight, Emperor Han saw Yao Qian's heroic appearance, and his eight-character beard was extremely beautiful, so he asked Yao Qian first: "Yao Aiqing, how many years have you been in the Ministry of Industry?" ”

Yao Qian bowed, but his voice trembled slightly, and said, "Back to Your Majesty, it's ...... It's been over eight years! ”

Emperor Han saw that although his demeanor was a little out of shape, he generally felt that this person was still good, and asked lightly: "Hmm!" So you already know a lot about the situation in the Ministry of Industry, right? ”

Yao Qian smiled slightly and said, "All this has to be thanks to Pei Shangshu's careful guidance!" If there is no old man for him, Weichen would not be able to progress. ”

Gao Han listened to it on the sidelines, how could the two of them still pull up their parents, the more they talked about at this time, the more their chances of promotion might become.

Emperor Han continued to ask Yao Qian: "Did you know about the flooding of the Yellow River two days ago?" ”

"Back to Your Majesty, this report was only learned by our Ministry of Industry last night, and this morning Pei Shangshu must come to report to His Majesty despite his illness, and the minister only learned about it in the morning." Only then did Yao Qian gradually overcome his fear and replied in an orderly manner.

Emperor Han twisted his beard and said, "Then Yao Aiqing, can you tell me if there is any way?" ”

Yao Qian pondered: "The minister has a word, as long as the Yellow River reaches the flood season every year, either the river overflows, or the estuary bursts, Weichen has surveyed the Yellow River along the spot, mainly because the lower-level officials are not firm in building the embankment, or the embankment is too low, so Weichen feels that the dam should be increased high, widened and thickened, and the farmland along the river can be subsidized by the imperial court to relocate to the upstream to reclaim wasteland, and the towns along the river can be moved to a high place, so that the wasteland can be reclaimed, and the people can avoid floods for many years. If we could send another overseer, it might be better! ”

Emperor Han nodded, and also felt polite, "Yao Aiqing is really experienced, well, the position of the waiter of the Ministry of Works will be ......."

Before Emperor Han finished speaking, Gao Han hurriedly said: "Your Majesty, Weichen also has a method to control the flood!" ”

"Oh?" Emperor Han looked at Gao Han curiously, "Tell me about it!" ”

"Yes!" Gao Han swore and said, "Wei Chen thinks that although what Lord Yao said is a good way, it is a good strategy. If the dam can not withstand the river water, then the lethality of the flood will be stronger, the scope of the impact will be wider, and the people will only be more affected, then it is not a good intention to do bad things, then the money of the imperial court is still not spent on the real place, and let the people along the river move to other places, I am afraid it is difficult, after all, the people on both sides of the Yellow River live here, the relocation is time-consuming and laborious, and the people are easy to accumulate grievances. ”

After Yao Qian listened to Gao Han's words, he only felt a chill down his back, beads of sweat rolling on his forehead, and he couldn't help but curse in his heart.

Emperor Han listened to it with relish, and it seemed that what Gao Han said was not unreasonable, if the rain in the flood season was stronger, maybe the embankment would be useless, not only that, but it could also cause more serious consequences, "Then Gao Aiqing, what can you do to solve this problem?" ”

Seeing that the emperor was getting more and more interested, Gao Han was secretly happy in his heart, and said with a smile: "Weichen thinks that artificial diversion and river flow are more reliable than building embankments!" ”

"Artificial diversion? River water flow? Emperor Han asked curiously.

Gao Hanzhi explained proudly: "That's right! After the Yellow River has undergone many embankments and dams, the river channel has become narrower and narrower, and the embankment line is also meandering, if there is a flood, it is easy to have poor discharge, then there will be a problem of breaching, so if you carry out artificial excavation and divert the river water, then you can solve the problem of bursting the embankment. Then dig the canal and then divert the water from the river, so as to reduce the intensity of the flood and let the flood water go through the floodway, which can solve the problem of overflow of the river and reduce the risk of the levee bursting. In addition, it is supplemented by dredging the river channel, which can also make the river water smoother. ”

Although Yao Qian also felt that what Gao Han said was very reasonable, but if he surrendered so soon, wouldn't the position of the squire of the Ministry of Works have to be given up again, so he raised his eyes and glanced at Gao Han, and said in a non-yin and non-yang manner: "Lord Gao, you may not have much experience in the Ministry of Industry for a few months, and you don't know the difficulty of dredging the river." Dredging the river is not only time-consuming, labor-intensive, but also useless, and after a few years, the Yellow River will still be deposited with sediment and the river will be blocked. ”

Yang Youxian, the secretary of Dali Temple, also said: "Yes, dredging the river has been done in previous years, but in the end it is useless!" ”

As soon as Yang Youxian said it, many ministers also echoed it, saying how could this method not work, and saying that Gao Han would only talk on paper.

The crown prince Liu Yan saw that those ministers secretly changed their concepts, and he was quite dissatisfied in his heart, and said in the class: "Grandpa Huang, I think the ministers may misunderstand what Lord Gao meant, since dredging the river is useless, then there is no need to do it, but Lord Gao's first two opinions, the diversion of the river and the diversion of Sun Er, I think it is feasible, and it is more prudent than what Lord Yao said about building a dam!" ”

Emperor Han glanced at Pei Yuanjin, and when he saw that he closed his eyes and didn't speak, he frowned again and asked Gao Han: "Gao Aiqing, the two opinions you said earlier are good, but do you have any methods for dredging the river?" ”

Gao Han smiled slightly, he had already expected everyone's thoughts, and replied unhurriedly: "The ministers are right, dredging the river is time-consuming and laborious, and once the sediment accumulates in the coming year, then it will have to be cleaned up again, which really doesn't make sense." But Wechen has a way! ”

The crowd's eyes widened and they looked at Gao Han curiously. Emperor Han was also quite curious, and couldn't help but look up and ask, "Oh? Gao Aiqing, please come soon! ”

Gohan continued: "Narrow the river! ”

"Narrowing the river?" Yao Qian smiled disdainfully and bitterly, "Once the river channel is narrowed, I am afraid that it will accelerate the flow of water, so if we do it, it may accelerate the danger of breaking the embankment, right?" ”

"Lord Yao doesn't seem to have heard what I said before!" Gao Han sneered, "Narrowing the river channel can speed up the flow of water, but it can also allow the flow of water to automatically wash away the sediment, if you build a flood distribution area as mentioned above, then you can solve these problems together!" ”

Gao Han said that, the prince and others clapped their hands one after another, and even Pei Yuanjin nodded silently on the side at this time.

At this moment, Emperor Han already knew in his heart, and said with great satisfaction: "Since this is the case, I will appoint Gao Han as the squire of the Ministry of Works, and go to work on the same day, and cooperate with Pei Lao to control the floods of the Yellow River clearly!" ”
