But Gu Tianya stretched out his hand, pointed at the first small plate, and said: "First, let's talk about the Youyun States."

However, he did not speak directly. Instead, he looked at the children and said with a smile: "Uncle, let me ask you a question first. Does anyone know how vast this area is?"

This is Gu Tianya's habit. He likes to teach through learning.

Whenever he talks about government affairs, he always poses a few questions first, so that he can not only test the children, but also deepen their understanding.

His question is not difficult.

As the crown prince of the Tang Dynasty, Li Chengqian had begun to study government affairs two years ago. This boy was the first to raise his hand and said confidently: "Uncle, nephew, can you answer?"

Gu Tianya glanced at him and encouraged him with a gentle voice: "Speak."

Li Chengqian took a breath and said loudly: "Since ancient times, the land of Yanzhao has been called sixteen states, and the area you are currently in charge of, uncle, is the five northernmost states..."

"They are Youzhou, Jizhou, Ruzhou, Shunzhou, and Zhuozhou."

"In addition to these five states, there are also Tanzhou in Hebei Province and Yunzhou in the northwest border. In total, there are seven major states, which are now called the new Youyun states."

"If you go here from Yunzhou in the west, the distance is about 800 miles, and from here to Jizhou in the east, the distance is about 300 miles. Eight hundred plus three hundred is one thousand miles.

First, from this we can clearly know that the territory of the Seven Youyun States is eleven hundred miles."

Gu Tianya laughed and praised: "Cheng Qian is very good and studies very hard. Uncle, when I was thirteen or fourteen years old, I didn't know as much as you did."

Li Chengqian quickly leaned over to salute and said respectfully: "This is what my father and uncle taught me well."

Gu Tianya laughed again, looked at the children present, and asked: "As for the size of the territory, Li Chengqian has already answered, so my uncle will ask you a second question, what is the population of the seven Youyun states now?

?”

Gradually, the problems begin to become more difficult.

This question is obviously not something that children can answer.

Cheng Chumo suddenly stood up and mustered up the courage to say, "Master, I know."

Gu Tianya smiled happily and praised without hesitation: "Once upon a time, you guys were most afraid of answering questions. Whenever you asked a question for the teacher, you would always shrink back. Now that you can answer proactively, you can see that you have made great progress."

Cheng Chumo took a deep breath and said softly: "This is because Master has put in countless painstaking efforts to make my disciple make some progress. Three years ago, Master took back the Youyun Prefectures from the Turks. From that day on

, you have been cultivating me."

"In the past three years, you have asked me and my junior brothers to serve in various yamen. When we did something wrong, you did not punish us. When we made some achievements, you praised us. It is precisely because of your continuous encouragement that we have achieved success."

Let us gradually master a lot."

Cheng Chu paused silently, and then continued: "For example, the population of Youyun states can be answered by Tu'er and others in one sentence. Tu'er first answered the population of Youzhou, because Youzhou is the entire Youyun state.

center of."

He paused again and said again: "Three years ago, the population of Youzhou was more than 80,000 households, and the other six prefectures combined, barely only about 60,000 households. A total of ten

Forty thousand households, this was the total population of the seven Youyun states at the time."

Gu Tianya nodded and asked with a smile: "What about now?"

Cheng Chumo took another deep breath, his voice gradually became more proud, and he said loudly: "Three years have passed, and the Youyun states have become prosperous under the rule of Master. Now the population has increased dramatically, and it is no longer what it was before...

…”

"First of all, there were two large-scale migrations of people. One was the people from the pass voluntarily fleeing the famine, and the other was the people from the aristocratic families who wanted to grow cotton. These two migrations were less than a year apart, but they brought more people to Youyun Prefectures.

It has a population of 200,000 households.”

"There are 200,000 households, each with about five to seven people. These people have become Youyun people, and the total number is about 1.2 million."

"Hey, no, it's not just 1.2 million, but 1.5 million. Since Master encourages people to have children, many children have been born in the past two years... Although these children have not yet become adults, they should

Be included in the population count.”

"In addition to these two large-scale migrations of people, our Youyun Prefectures also had another population explosion. What was it? It was the Han women who returned from the grasslands."

"At the beginning, we defeated the Turks and forced them to release 300,000 Han women. The fate of these Han women once caused a headache for many people, but after three years, it has been gradually resolved."

"Nearly all of the 300,000 Han women are married. Each Han woman helps us Youyun find a husband, which increases our population by another 600,000."

At this time, I suddenly heard a little guy chuckle and remind me: "Elder brother, you are negligent again. After the Han women form a family, the babies they give birth to will also be included in the population."

Cheng Chumo was startled at first, then nodded quickly and said, "Yes, yes, it is true. Three hundred thousand Chinese women form a family, and in the past two years, at least one hundred thousand babies have been born."

The boy calculated silently in his mind for a long time, and finally gave a solemn answer, saying: "Today, the total population of the entire Youyun States should be about three million..."

"How did you get this number?" Gu Tianya asked with a leisurely smile.

Cheng Chumo said without hesitation: "The original 140,000 households were 600,000, the two migrations added 1.5 million people, and after the Han women formed families, the number increased to 700,000.

"

Three million people, this is the total number of the entire Youyun States today.

…

Gu Tianya slowly exhaled and said: "The territory is 1,100 miles, and the population is about 3 million. It sounds good at first glance, but things in the world need to be compared..."

He paused slightly as he spoke, and suddenly asked: "Who can tell my uncle what the territory and population of the Tang Dynasty are?"

This question is not difficult, everyone present knows it.

Li Chengqian stood up again and replied: "There are now ten roads in the Tang Dynasty. The territory from south to north is 4,500 miles, and if the distance from east to west is calculated, it is more than 6,000 miles. Last year

At the beginning of the year, the Chaotang Household Department conducted a population census, which showed that there were 15 million people in the country, which is equivalent to about 3 million households."

"That's not right!" Gu Tianya shook his head slightly and said: "There will be huge deviations in the population statistics of the previous dynasties. In fact, according to my uncle's speculation, the total population of the Tang Dynasty is at least 20 million."

At this time, Li Shimin interjected and said: "Yes, it should be 20 million people."

Gu Tianya looked at the children present and said with profound meaning: "Can you understand now? Why I want to build a vassal state. The Tang Dynasty has a territory of 6,000 miles and a population of 20 million. What about the Youyun states?

?The territory and population are all very different..."

Suddenly, a little girl stood up and said crisply: "But uncle, you have just conquered Goguryeo. This part of the territory and population already belongs to you. If they are included, your power has surpassed that of the vassal states."

Gu Tianya chuckled and said: "As you little girl said, the words 'just laid' are worth noting. Since it was just laid, it means that it has not yet been completely laid. How can a place that has not yet been completely stabilized be

Does it count as the foundation of the founding of the country?”

He sighed softly as he spoke, and said with emotion: "My strength is still too weak. As a human being, you must recognize reality."
