Just as Yang Chengying was about to discuss with Zheng Zhilong about going to sea, Liu Xingzuo came.

He didn't come alone.

In addition to Liu Xingzuo, there are also Sun Degong, the secretary of the Ministry of Industry, Luo Xiujin, the left waiter of the Ministry of Industry, Ma Mingpei, the right waiter, Jierharang, the governor of Liaobei, Yang Fangxing, the governor of Jilin, and Luo Huijin, the governor of Changchun Prefecture.

The Ministry of Industry is different from the Ministry of Agriculture and Commerce.

The Ministry of Industry follows the tradition and is mainly responsible for the construction of infrastructure within the territory, which is about the same as the Ministry of Communications and the Highway Transportation Bureau.

The "industry" of the Ministry of Agriculture and Industry refers specifically to "industry".

Coming to such a group of people made Yang Chengying feel that things were a bit big, so he asked Zheng Zhilong to leave.

He summoned these ministers in the middle of the room.

He also asked the attendant to bring a charcoal basin, and everyone sat around it.

"You came all the way to see me, I don't know what's the big deal?" Yang Chengying asked.

As soon as the expo ended, Zilharang and others were going to Jilin to take up their posts.

This made Yang Chengying feel the seriousness of the matter even more.

Liu Xingzuo didn't answer, and glanced at Yang Fangxing.

It was clear that Yang Fangxing was the leader of the meeting.

Yang Fangxing didn't speak immediately.

Glancing at it again, his immediate boss, Zilharang, saw that he also nodded, Yang Fangxing said:

"When the king went to the northeast, he sent someone to measure the height of the river and recorded it in the book."

"That's right." Yang Chengying watched them fight the lawsuit, and was a little funny, "I hope that after you go to the Northeast, the grain road will not be interrupted due to the change of water." ”

"The king's heart is good, but there is one thing that the minister disagrees with."

"What's the matter? But it doesn't hurt to talk about it. ”

"The further northeast you go, the more the river is geographically constrained, and the flow becomes shallower and shallower. The famous Nenjiang River will also have times when it is impossible to sail. ”

"I know that."

"The king, if you want to dig up the Yitong River and use the river water to irrigate the rice fields, the minister thinks it is inappropriate."

"Why?"

"The great river sails by the depth of the water. Digging up large rivers and building irrigation canals is indeed a good way to grow rice, but it will not last long. ”

"At least not until the railway opens," Yang said. The king knows that last year alone, millions of people poured into the country, and the water consumption was extremely large.

If the rice fields are re-irrigated, the consequences are unimaginable. ”

As he spoke, Yang Fangxing took out the hydrological data that Yang Chengying had initially measured, as well as his own observation data of the river channel when he was on an errand in Houjin.

The ancients were far inferior to today's people in terms of mathematical calculations. But in terms of data analysis, especially Yang Fangxing, a master of river management, is quite good.

Through analysis and calculation, it is clear how many estuaries can be excavated and how much fertile land can be irrigated in each area.

Yang Chengying raised his head in surprise and looked at Yang Fangxing.

In the era when there was no computer, Yang Chengying didn't expect his subordinates to engage in fine management, but he didn't expect Yang Fangxing to be so capable.

"This is obtained by the minister from visiting the new strongholds of Qingyangbao (Changtu) and Lishucheng, through the observation and statistics of last year."

Yang Fangxing introduced.

"Amazing!" Yang Chengying gave a thumbs up.

This kind of data analysis ability is the most lacking.

"The minister asked the king to temporarily withdraw his order and put the matter of rice on hold for the time being. When the railway is repaired to Acheng, it is not too late to proceed. ”

Yang Fangxing clenched his fists and said seriously.

"Your idea is very good, and I couldn't agree more." Yang Chengying nodded.

The mountains and rivers in Northeast China are vast, and there are two major water systems in total - the Liao River water system and the Heilongjiang River water system.

The Liao River flows into the Bohai Sea, and the Heilongjiang River flows into the Pacific Ocean.

The upper reaches of the Heilongjiang River are the Krulun River, the middle reaches are the Ergun River, and the lower reaches are the Heilongjiang River.

The northern tributaries are the Nan River, the Shilka River, the Jieya River, the Burea River, and the Amugun River.

The southern tributaries, Hailar River, Huma River, Nenjiang River, Songhua River, Ussuri River.

However, unlike the great rivers in the south, many rivers in the north will break for a while, and there will be long ice periods in winter.

Historically, in the last years of Kangxi, there was already a situation where the grain road was not smooth.

Yang Chengying's era has not been interrupted for the time being, because the population is temporarily insufficient.

Although the Manchu Qing Dynasty closed the northeast, it could not stop the land crisis, and many people broke into the eastern part of the country.

In the absence of detailed planning, river water is used for irrigation, resulting in land erosion, desertification and silt accumulation in river channels.

Eventually, long-distance shipping disappeared.

Short-distance river transportation also disappeared with the advent of railways.

Liu Xingzuo spoke: "King, look! Yang Fangxing is more suitable than me to be the governor of Caoyun, and the minister wants to change positions with Yang Fangxing, and the minister is the governor of Jilin. ”

Yang Chengying listened, his eyes swept over everyone present, and they all showed a look of approval.

However, Yang Fangxing was a little flustered and refused: "Caoyun has river workers and soldiers, and he has to face possible looting, but the minister has never brought troops, no." ”

"If you don't lead the army from the beginning, you can't learn."

Yang Chengying agreed with what Liu Xingzuo said, "If you are afraid that you will not be able to lead the soldiers, you can ask Liu Xingzuo's brother Liu Xingpei to assist you." ”

Liu Xingzuo nodded in agreement.

"Thanks to the king's attention and your trust, the minister is willing to give it a try."

Yang Fangxing saw that he couldn't get rid of it, so he had to clench his fists and say.

Yang Chengying saw him accepting, nodded and said: "Okay, in the future, you will be the governor of Caoyun, and I will give you the title of superintendent of the imperial history, in charge of Caoyun and river affairs." ”

"Minister, take the order!" Yang Fang rose up and thanked him.

Yang Fangxing's incident reminded Yang Chengying that he should vigorously cultivate "science students" and handle some government affairs through data statistics, calculation and analysis.

If you don't make a careful calculation, you can't get it done.

However, for now, there are very few people who have this ability.

Babyy.

Yang Chengying set his sights on the children he raised, so he summoned Huang Zongxi.

Huang Zongxi thought at first that Yang Chengying was still for the sake of Jiangnan literati, so he said:

"Your Majesty, the minister has already written a letter, and it will take some time before there is a reply."

"I'm not here for this."

Yang Chengying said: "I want to ask you, have you seriously taught children mathematics. ”

"Yes. Computational methods, sampling, and variable analysis are all areas of my teaching. ”

Huang Zongxi replied.

Half of these skills are taught by Professor Yang Chengying.

"Who do you think stands out in this regard?" Yang Chengying asked.

"In terms of the number of techniques, the minister thinks that the second son is quite suitable. He is young, but he is quite talented in this area. ”

"Oh, then you should focus on developing his talents in this area."

"I see."

Huang Zongxi suddenly remembered something and asked Yang Chengying: "Your Highness, although you are in the prime of the Spring and Autumn Period, why haven't you established a son for a long time?" ”

"Huh?" Yang Chengying was stunned.

"Some words are a bit outrageous. For example, the king loved his second son and intended to make him his son. ”

"What are these words?"

"It's normal for you to let the second lady manage those children and let outsiders know that they want to get into the air.

They all think that you are letting the second lady train a new team so that they can replace the eldest son in the future. ”

"It's all bastard!" Yang Chengying was a little angry.

"Historically, there have been a lot of disagreements between fathers and sons and brothers because of this kind of thing."

"Don't talk about it, I know it in my heart."
