I make a popular science video and all the emperors learn from it!

[Popular science continues. ]

[Why did the small Huaihai region gather at least thirty insurgents and founding emperors in history? ]

[The Huaihai region includes four areas: northern Anhui, eastern Henan, northern Jiangsu, and southern Shandong. ]

[First, these four areas are adjacent to each other. ]

[The Central Plains Mandarin is widely used, and the language and customs are similar. In ancient times when there was no Mandarin, there was no communication barrier. ]

[The second reason is the geographical location. ]

[That is, the curse from the Yellow River. ]

[Although the Yellow River gave birth to the earliest Central Plains civilization. ]

[However, the mother river has a bad temper! ]

[Since ancient times, there has been a saying that "the river bursts its banks every three years and changes its course every hundred years." 】

【Until now, Zhengzhou and Kaifeng on the banks of the Yellow River are both rivers on the ground, especially the ancient city of Kaikai, which has been buried several times. 】

【When the river floods, the land is covered with mud and sand, and the original fertile fields quickly become salinized. 】

【Grain production has decreased. 】

【The people nearby who rely on the land for food have become even poorer. 】

【If this extreme survival mode comes once in a lifetime, maybe we can still bear it. 】

【But the Yellow River has always been a time bomb. 】

【Three years a small flood, five years a big flood, is commonplace. 】

【Under such repeated torture, no matter you are a poor peasant or a wealthy family, when the flood comes, everyone will lose everything. 】

【Either drown or starve to death. 】

【Become a mule and horse kneeling tribe overnight! 】

【Those who were lucky enough not to be drowned or starved to death had to become refugees and flee for their lives. 】

【Along the way, they only wanted food, stole, and robbed houses. 】

【As long as they could survive, they dared to do anything! 】

【Therefore, they left a bad impression on outsiders that "poor mountains and bad waters produce unruly people." 】

【After the flood, they returned to their hometown. 】

【What they found was a mess. The original boundaries had been washed away by the flood. 】

【So, the brave people began to rob the weak. 】

【Under the rules of the jungle, whoever has the strongest fist can survive. 】

【After experiencing countless floods of the Yellow River, the local people were even more reluctant to buy land to grow crops. 】

【Because once the flood washed away, there was nothing left. 】

【Those wealthy villagers prefer to buy knives and practice martial arts, so that they can hurt others if they are close to them, and protect themselves if they retreat. 】

【Over time, the people in the Huaihai area have developed a folk custom of being competitive, brave and aggressive. 】

【If it happens that the old emperor is incompetent at this time, then the spring of their entrepreneurship has come! 】

【As long as they raise their arms and shout, "The court is a bastard, bullying the people" and "Are there any kings, princes, generals and ministers?"】

【There will be a group of people who will follow and start a rebellion. 】

【Therefore, the countless floods on this land have caused countlessCommon people, parents are gone, wives and children are separated. 】

[This group of people who have nothing but a strong desire to survive, once pushed to the extreme, will easily rise up. 】

[Become heroes competing for the Central Plains. 】

[......]

"So that's how it is, thank you for the light curtain!"

"I was wondering why the people in that place are so fierce, it turns out there is this reason."

"Alas, nothing is absolute in the world, being close to a river may not be a good thing."

"......"

After reading the light curtain's explanation, the ancients suddenly realized.

Understood why the Huaihai area was prone to rebels.

It's really sad and lamentable.

Qin Dynasty.

Ying Zheng didn't realize it until now.

Applying the above two reasons to the fact that the Huaihai region is prone to the emergence of rebels, everything seems reasonable!

First of all, the language is common and it is all plains.

When communicating, it is almost like being from the same hometown.

Secondly, it is because of the Yellow River.

Ying Zheng pressed his finger between his eyebrows and said angrily: "Yellow River, how should I deal with it?"

Even if he is the emperor and the master of the world, he can't control a river.

Just at this time, he glanced at the light screen.

Just then, the question and answer pop-up window popped up!

[Quick answer session! ]

[Which of the following areas does not belong to the Huaihai region? ]

[Option 1: Central Anhui. ] (To read the exciting novels, go to Feilu Novel Network!)

[Option 2: Eastern Henan. ]

[Option 3: Northern Jiangsu. ]

[Option 4: Southern Shandong. 】

Ying Zheng's eyes lit up, and he blurted out "Option 1!" almost instantly.

[Correct answer. ]

[Congratulations to Qin Dynasty Ying Zheng for answering the question successfully and winning: a manual on water prevention and flood control. ]

[Hint: This manual records the experience and actual cases of water prevention and flood control in all dynasties. ]

In an instant.

A small booklet appeared in Ying Zheng's hand.

Then he happily opened the manual to check.

After a while.

He laughed up to the sky and said, "I have nothing to worry about!"

Tang Dynasty.

Li Shimin was a little upset. []

The area near Huaihai is really "a place of outstanding people and beautiful scenery"!

It turns out that it is really inherited from ancestors!

How to do this?

Especially after knowing that a great traitor would pop up in that place at the end of the Tang Dynasty, Li Shimin couldn't keep his temper.

763 "What should I do!"

"Can you give me some advice?"

He glanced at the ministers around him.

Changsun Wuji stood up and replied: "Your Majesty, there are only two ways now."

"One is to separate the people in the Huaihai area and relocate them to various parts of the country to prevent them from rebelling together."

"The second is to increase the management of the Yellow River and reduce the number of dike breaches."

"I can only think of these two ways at the moment."

The other ministers looked at each other and nodded. They had no better solution.

We can't just kill all the people in Huaihai area for no reason, right?

Li Shimin sighed and said, "Then let's use both methods together."

"Yes, Your Majesty."

The ministers responded in unison.

Ming Dynasty.

Zhu Yuanzhang couldn't help but glance at the Huaixi officials nearby.

These ministers are all from his hometown.

So, these people are the same as us!?

From our ancestors, we like to be brave and aggressive.

Then we have to be more careful about them.

Zhu Yuanzhang thought in his heart, but remained calm on the surface.

We can't be stabbed in the back by our fellow villagers!
