After the Battle of Jinzhong, the Han Dynasty experienced a smallpox epidemic, which made the Han Dynasty a little gloomy. Until Zhang Yuanjin was named queen, the Han Dynasty was finally out of the gloom.

The sixth day of April in the first year of the rise of the Han Dynasty (AD 240).

One month after Jin was granted the title of Empress, Zhang Yang was in a good mood today. She did not put on her luxurious clothes, but wore simple clothes, and appeared thirty miles south of Chang'an City with the emperor Liu Chan.

"Your Majesty!"

"This is our royal farm?"

Zhang Yang asked, pointing to a piece of farmland in front of him. A few days ago, Liu Chan had told him that starting from this year, they would go out of the city to help farmers in the fields every year.

In the past, kings from various countries actually helped farmers during spring plowing, but most of them just went through the motions, just going to the fields and doing whatever they wanted.

Liu Chan wanted to change this rule. At the end of last year, he asked Xu Shu to find him an uncultivated field, and he wanted to improve it into a royal farm.

It's early spring now, and people are busy planting rice and so on.

Liu Chan has no interest in growing rice now. He has done the best he can in improving rice. As for the ability of later generation Grandpa Yuan, he really doesn't have it.

He can only plant at intervals and raise seedlings in greenhouses. So far, this method has greatly improved Dahan's grain output.

As for the field of this royal farm, it is not very wide. It is just a dry field of nearly ten acres. The population in Guanzhong is still sparse. Years ago, Liu Chan asked Xu Shu about the total population of the Han Dynasty.

According to Xu Shu, the current population of Yizhou is 320,000 registered households and 1.63 million people;

Liangzhou has 60,000 registered households and a population of 310,000;

Yongzhou has hundreds of thirty thousand registered households and a population of 690,000;

The number of registered households in Bingzhou is 53,000, with a population of 28.

The total number of registered households in the four prefectures of Yi, Yong, Liang and Bing is 563,000, with a population of 2.91 million.

As for the Western Regions, Nanzhong, and Southwest regions, the imperial court did not directly govern them, but were managed by local clans. However, the number of registered households in these three regions is more than 300,000, and the population is more than 1 million.

Liu Chan was naturally speechless when he heard this population figure. When later generations read the Romance of the Three Kingdoms or the Chronicles of the Three Kingdoms, they became a little curious. In history, when the Shu Han Dynasty fell, the country's population was only more than one million.

But, is this really the real population?

Of course not. After talking about the registered population, Xu Shu also has another data on the number of households in each state:

Yizhou has 840,000 households and a population of 4.26 million;

Liangzhou has 123,000 households and a population of 695,000;

Yongzhou has 189,000 households and a population of 1.33 million people;

Bingzhou has 87,000 households and a population of 422,000 people;

According to this data, the Han Dynasty has a population of more than 6.7 million, including only Yiyongliang and the four prefectures, but the registered population is only more than 2.9 million.

No need for Xu Shu to explain, Liu Chan certainly knew that the extra data between the two data was naturally the household registration concealed by the wealthy families.

Although the total number seems pretty good, counting only four states, Dahan now has a population of close to 7 million, but compared with some first-tier cities in later generations, which often have a permanent population of more than 20 million, it is still too small.
p>

In this era, population is a very important asset to any country.

It was also because the population was too small that Liu Chan wanted to open up a royal farm, which did not trouble Xu Shu. He didn't worry too much and found this fairly good dry land thirty miles south of Chang'an City.

Liu Chan has been waiting these past few months for the arrival of spring.

Now is the spring plowing season. This morning Liu Chan led Queen Zhang Yang, Prince Liu Chen, King Liu Tan of Qin, Princess Liu Rongyue of Hanyang, and a group of civil and military ministers.

"Chen'er, Tan'er!" Liu Chan called.

Liu Chen and Liu Tan hurried over. Liu Chan pointed at a bag of corn kernels and asked them, "Do you know what this is?"

Liu Chen was the first to answer: "Go back to my father, this is the golden grain of the Sasanian people!"

Liu Tan echoed.

But Liu Chan waved his hand with a smile and said: "Don't listen to the nonsense of those businessmen. They named this thing golden grains just to sell it at a good price."

"Then..." Liu Tan frowned and asked, "Father, what should this thing be called?"

Liu Chan glanced at the two of them and said affirmatively: "From now on, this thing belongs to me, and I will name it - corn."

"Corn?" Xiao Jindou said with a smile: "Father, why do you call it corn?"

Xiao Jindou's words suddenly made Liu Chan speechless. He had never thought about why this thing was called corn, but he couldn't tell because his father was a time traveler. In his previous life, this thing was called corn.

However, Liu Chan looked at the prince Liu Chen and deliberately asked: "Chen'er, tell me, why did your father name him Corn?"

Liu Chen was also a little confused. He looked at the corn kernels carefully, pondered for a while, and then said noncommittally: "Father, this thing should be as crystal clear as jade. My father said that day that this thing has full grains and is a high-yielding grain.

So call it corn?"

Listening to Liu Chen's answer, Liu Chan also felt a little embarrassed for his son, but it sounded good. When the corn is mature, it is not crystal clear. Although it is not as good as jade, the answer is not bad. After all, he is only eight years old now.

So Liu Chan nodded slightly and said with satisfaction: "Yes, what Chen'er said is good." He changed the topic and preached: "Chen'er, Tan'er, you must remember that a king must always think of the people.

."

"As a monarch, you must first let the people have food to eat and clothing to wear." He looked at the two of them and asked seriously: "If the people don't have enough to eat and don't have enough clothes to wear, do you think the people will still support you?"

?"

Liu Chan originally wanted to educate his son in this way. When he becomes emperor, he must always think about the people and ensure that the people have enough food and clothing. Because in his memory, whenever there was rebellion in the past dynasties, it was more or less because the people could not afford to eat.

Fan, had no choice but to choose to rebel against the imperial court, and then rose up.

However, as soon as Liu Chan finished speaking, Qin King Liu Tan said: "Father, the people who do not support the monarch are all rebellious people. In the future, if anyone dares not to support father or the prince..." Liu Tan just said this, Liu Chan couldn't help but feel

He was stunned for a moment, wanting to hear what else he wanted to say, and deliberately asked Liu Tan: "If this is the case, what will Tan'er do?"

"Go back to your father!" Liu Tan slapped his chest hard with his small hand and said firmly: "I should ask for orders to send troops to annihilate them."

"Suppress... suppress... destroy?" Liu Chan was stunned for a moment, and then asked: "If all the people in the world rebel, what can be done?"

Liu Chan's tone was obviously not quite right. Liu Tan did not dare to answer. He felt that his answer did not satisfy his father. He turned to look at his younger brother Liu Chen, who was also a little panicked.

Seeing that the two sons were silent, Liu Chan patted their shoulders lightly, and then said seriously: "Remember, people will not rebel for no reason. Once they rebel, they will either be bewitched by others, or they will

Our failure as kings makes it difficult for them to survive and forces them to stand against us."

"You all must remember that water can carry a boat and also capsize it;" Liu Chan said: "The boat is like the court of a country, and the water is the subjects of the world. They can support the court and overthrow the unethical court.

”

"I have remembered it!" Liu Chen saluted. Liu Chan immediately looked at Liu Tan and asked, "Tan'er, do you understand?"

Liu Tan was stunned, because he was just a king, and naturally he would not be a monarch in the future. This matter seemed to have nothing to do with him, as long as he assisted the king with his heart.

"I understand!" Liu Tan also responded.

After Liu Tan finished speaking, Liu Chan said with satisfaction: "In the future, you brothers will all become the kings of a country, so you must remember your father's words. Those who win the hearts of the people will win the world, and those who lose the hearts of the people will lose the world no matter how big it is."

."

"No!"

Seeing the obedient responses from his two sons, Liu Chan was satisfied. However, the Queen Zhang Yang beside him seemed a little embarrassed, and she frowned slightly.

After talking to his two sons, Liu Chan asked the eunuchs to summon the ministers to him.

"My dear friends!"

Liu Chan grabbed a handful of corn, smiled and said to several ministers: "This is the food of the Sassanid people in the Western Regions. The grains of this corn are full and crystal clear as jade. Today I will plant this corn on this royal farm. If it is

We can have a good harvest and we will promote it nationwide in the future."

Here we go again——

The ministers were a little stunned. Not many people knew about this thing. Only Xu Shu and Zhuge Liang, a few high-level officials, had heard Liu Chan talk about it before.

However, this is the first time they have encountered this thing. Can it really be a good harvest?

Liu Chan didn't care about them. After a brief conversation, he led several eunuchs and Queen Zhang Yuan to personally go down to the fields and start planting corn.

When it comes to growing corn, Liu Chan was a child in the countryside in his previous life, so this will naturally not be a problem for him.

Leveling a small piece of land, then spreading corn on it, adding manure and water, and finally covering it with tent cloth, this is the cultivation of corn seedlings, which made the ministers stunned.

One of the middle-aged officials couldn't hold it back and asked: "Your Majesty, why is this so troublesome? Wouldn't it be better to just scatter it on the ground?"

"Haha!" Liu Chan rolled his eyes and said angrily: "It's okay to spread it on the ground, but it's difficult to achieve a bumper harvest. Does Aiqing still remember how to grow rice?"

As soon as Liu Chan said this, the man immediately shut his mouth.

Because the current rice cultivation in the Han Dynasty is because Liu Chan improved the planting methods, and the current harvest is more than twice that of the past. Since the emperor said this, he naturally has his reason.

If it were just corn seedlings, Liu Chan wouldn't have spent so much time today. The corn seedlings were actually completed very quickly, mainly because there were not many corn seeds.

After more than an hour, the corn seedlings were completed. Looking at a row of ground tents made of tent cloth, everyone thought that today's work was over.

But at this moment, Liu Chan asked two eunuchs to carry a bag of potatoes over.

These potatoes were also brought by the Sasanian merchant Salotto, but there was only one bag, which was about a hundred pounds.

These potatoes had been stored in Weiyang Palace for three or four months. When they were taken out, they had basically begun to sprout. Looking at these sprouted potatoes, Liu Chan was very satisfied.
To be continued...
