Chapter 123 South Low North High
The geography teacher noticed that Ji Chenxing was staring at the map in a daze.

The geography teacher is a middle-aged man, and he is also a professional teacher at the university.

But unlike the retired history teacher, he is still teaching in school. He comes to the Ji family to tutor Ji Chenxing, just to give face to Ji Huaiyu.

Before coming, Ji Huaiyu told him that his daughter had never studied geography and might have to start from the basics, and hoped that he could be more patient.

The geography teacher was actually a little unwilling at the time. He thought that we could ask the middle school teachers to lay the foundation, so asking him to come was like "killing a chicken with a butcher's knife".

Ji Huaiyu shook his head and said, "Although my daughter has never studied geography, she is very intelligent. I am afraid that if she asks some fundamental questions, the middle school teacher will not be able to answer them.

"You should come. You professors can teach more completely."

The geography teacher wanted to decline, but he heard Ji Huaiyu say, "Try to teach first. If it doesn't work, I'll let you go and you'll still get your salary."

I had some friendship with Ji Huaiyu in the past, and after hearing what Ji Huaiyu said, I had no choice but to come and give it a try.

Ji Chenxing stared at the map in a daze, and the professor asked, "What did you see?"

The university professor still had some pride, so from the very beginning, Ji Chenxing's ignorant look when he looked at the world map made him firmly believe that he was right.

He asked Ji Chenxing this question because he wanted to hear what Ji Chenxing saw as the key point.

If what Ji Chenxing said was not what he wanted to hear, he would go to collect his salary after teaching the class and would not come again in the future.

Ji Chenxing thought for a few seconds and pointed to the river that ran from north to south. "When was this river dug?"

The middle-aged professor was stunned.

He had thought that Ji Chenxing would ask any number of questions, but he had never thought that she would ask when this river was dug.

At first glance, this question may seem a bit brainless, but if you think about it carefully, it is a complex question that involves history and geography.

"This is the Grand Canal." The professor pushed his glasses.

“When it comes to the history of this river, we have to start from the Spring and Autumn Period.

During the Spring and Autumn Period, the State of Wu dug the Hang Canal in order to conquer the State of Qi. Later in the Sui Dynasty, Emperor Yang of Sui mobilized workers from all over the country to dig, connect, and significantly expand and renovate the canal to the capital Luoyang and connect to Zhuo County, thus becoming the Grand Canal of Sui and Tang.

Later, it was renovated during the Yuan Dynasty... It has a history of more than 2500 years since its opening."

The geography teacher was indeed professional. He answered Ji Chenxing’s simple question very seriously.

The Liang Dynasty was only a very short dynasty, and if there had been no intervention, this river would not have appeared in Daliang.

Ji Chenxing observed the head and end of the river and asked the question he wanted to know most.

“What was this river used for when it was dug?”

"Hmm." The professor sighed softly. The question asked by this little girl seemed to have some purpose.

"It is used for commercial trade and the South-to-North Water Diversion Project."

Sure enough, Ji Chenxing's heart moved.

The issue of floods in the south and drought in the north will ultimately have to be implemented through the "South-to-North Water Diversion Project", and from a historical perspective, this river must be dug; it is only a matter of time.

In addition to Ji Chenxing, there were many people watching the live broadcast in ancient times. Especially those officials related to disaster relief, they were all smart when they saw this.

They have been paying attention to this matter for a long time and have been studying whether to dig the river, but they have no clue yet.

Ji Chenxing simply forced them to understand the answers to a few questions.

Although it is not early morning yet and this year's disaster has not yet begun, this does not prevent them from studying secretly at home.

What’s more, what Ji Chenxing broadcast was not ordinary either, it was definitely the standard answer.

An official was in a daze, and his wife grabbed his ear and said, "Why are you still in a daze? Write it down quickly, so you can raise your hand to show your ability next time you go to court!"

"Yes, yes, yes." The official said, and quickly wrote down what the geography teacher had said on paper so as not to forget it later.

When Jun Heng, who was reviewing memorials, heard the term "Water Diversion from South to North", he raised his head abruptly as if a keyword was triggered to see what Ji Chenxing was broadcasting live.

"South-to-North Water Diversion?" Ji Chenxing thought carefully.

In ancient times, there were floods in the south and droughts in the north. She had thought of the term "South-to-North Water Diversion".

However, in terms of terrain, the southern part of Daliang is low and the northern part is high. If they simply and crudely want to dig a river, they probably won't achieve the desired effect.

Ji Chenxing directly expressed his doubts.

As soon as she finished speaking, a comment appeared in her live broadcast room, asking the same question she had just thought of.

[I am really not the Son of Heaven (Jun Heng): Can this river really achieve water transfer from the south to the north? How can water flow from low to high places? ]

[I'm really not the emperor (Jun Heng): Why does Ji Chenxing think the same as I do? Hiss, Ji Zunxing is such a fool, he doesn't even want such a good precious girl, what is he thinking? ]

The ministers who were watching the live broadcast also saw this comment, but they could not see Jun Heng's name. They could only see this person with the nickname "I'm Really Not the Son of Heaven" calling Ji Zunxing a fool over and over again.

The ministers first marveled at who this person was and found that he was more thoughtful than themselves.

Then he suddenly realized that Ji Chenxing, a woman, could think of a problem that he couldn't even think of. He was simply unworthy of being a minister.

The ministers wiped the sweat from their foreheads with their wide sleeves, and then cursed in their hearts several times, "Ji Zunxing is really a piece of shit."

At the Ji family, Ji Chenxing is waiting for the answer from the geography teacher.

If it were in ancient times, she might not be able to find the right person to answer her questions; but in modern times, geography teachers are professional.

After Ji Chenxing asked this question directly to the geography teacher, the geography teacher did not keep him in suspense, and the indifferent expression on his face disappeared, replaced by a serious look.

For someone who has just started learning geography, it is actually very good to be able to think about questions about the terrain.

Moreover, the map he took out was not a map with contour lines. The fact that it could tell the height of the terrain showed that Ji Chenxing had either accumulated some knowledge in his daily life and had now mastered it;
Or maybe she has been paying attention to this issue for a long time.

No matter which one it was, it made the somewhat arrogant professor look at her with admiration.

The professor didn't say much and directly told Ji Chenxing the answer.

"Look, this river is not straight here, but has a bend, which is called Jiezhiqushi. The bend in the river can effectively eliminate the water level difference caused by the different ground heights and ensure that the river surface is flat. And here, ..."

After a few minutes of explanation, Ji Chenxing nodded, she understood.
