There is no doubt that the Tang Dynasty continued some of the systems of the Sui Dynasty.

At the same time, the Tang Dynasty inherited both the good and the bad, but during these years, the two emperors Li Yuan and Li Shimin were gradually changing those bad aspects.

For example, the law, during the period of Emperor Yang of the Sui Dynasty, the law once stipulated that those who stole a piece of money should be beheaded, and in the later period, some officials began to use this law to retaliate, as long as the other party could not tell the origin of the money, it would be punished as theft, and there was no room for relaxation at all.

This is also the reason why the Sui Dynasty rose up to attack it, Li Yuan abolished this law at the beginning of his accession to the throne, although this law actually no longer existed after the death of Emperor Yang of Sui, but at the legal level, this was not officially abolished.

The same is true of the Juntian system, which combined with the two decrees of the Rent and Yong Adjustment to create a strong Sui and Tang dynasties, and it can be said that the early Tang Dynasty was able to gain a firm foothold in the wars and destroy the Turks, and these two systems contributed greatly.

But there is also a problem, every Ding needs to pay the state two stones every year, which is called rent.

Pay two zhang of silk, three taels of cotton, or two zhang and five feet of cloth, three catties of hemp, which is called tune.

If the state does not need his service, he may pay 3 feet of silk or 3 feet 7 inches and 5 cents of cloth per day, and pay the amount of 20 days in lieu of service, which is called Yong.

Na Juan substitute service is Yong, also called Yong substitute service.

If the state requires him to serve, he shall be exempted from transfer for every 20 days of service, and if he has served for an additional 25 days, he shall be exempted from transfer, and for an additional 30 days, he shall be exempted from rent and transfer.

Normally, regular duty shall not exceed 50 days. In the event of a serious natural disaster such as floods and droughts, more than four-tenths of the crop loss will be exempted from rent, more than six-tenths of the loss will be exempted, and more than seven-tenths of the loss will be exempted.

This law is very good, and it has lightened the burden on the people to a certain extent.

However, there is a premise, that is, the state has enough land to distribute to the people.

In fact, from the beginning of the Wu and Zhou dynasties, with the rapid increase in the population of the Tang Dynasty, there began to be an avalanche of the Juntian system, and the rent-yong adjustment system based on the Juntian production naturally collapsed.

Of course, Li Shimin knew this truth, and he also knew that this was always a hidden danger, but before that, he couldn't think of a better solution.

"The people live on the land, how much land can be allocated to them overseas? Can the imperial court support these burdens? Li Shimin sighed secretly in his heart.

"This ......" Fang Xuanling was a little puzzled, and immediately set his eyes on Li Yuanjing.

He really doesn't know much about overseas, and the only ones he knows are three or two kittens, and it is okay to solve one state, but he is still very unconfident in his heart to solve the problem of the entire Datang.

"At present, it is known that Tamna can house at least 50,000 households, about hundreds of miles east of Tamna, that is, the southern part of the Wa Kingdom where Fang Xiang went before, and the courtiers and his soldiers have learned about the situation there, it is not the Wa country itself, and it is not far from the Wa country, but it is also an island, and there are not many people living on the island, most of them are mainly defeated Japanese people in the local war, and these Japanese people loot and make a living on weekdays.

The island is much larger than Tamna, and the climate is better than Yangzhou, and it is estimated that it can accommodate at least 200,000 households.

Then there is the southwest of the Ryukyu Island, Emperor Yang of the Sui Dynasty has sent Zhu Kuan, Chen Ling and others to go, the island is also a pleasant climate, there are not many aborigines, according to the available information, the Ryukyu Island can be resettled at least 500,000 households. Li Yuanjing first said the three known places.

Those unknown ones have not yet been explored, so he can't say so surely, and even these known, he didn't say too absolutely.

The island in the south of the Wakoku Kingdom is Kyushu Island, not to mention 200,000 households, it is easy to resettle one million households, and Ryukyu Island is the bay of the later generations, and it is like playing with one million households.

Therefore, in Li Yuanjing's eyes, the original sin of the large number of people and the lack of land lies in the fact that the imperial court does not want to forge ahead, and the place is not enough to think about opening up.

"These are just a rough estimate, how many people can be resettled, it depends on the next field trip to reach a conclusion, but the minister's personal feeling is that there is no problem in relocating three million households in these three places!" Li Yuanjing continued.

"Do you know how many people Datang has now?" Li Shimin frowned and said a little unpleasantly.

"There are always tens of millions, right?" This Li Yuanjing really doesn't know, anyway, he knows that the population of Datang is really a lot, look at the street, although not to mention that there are people everywhere, but walking around the mainland is full of population gathering areas.

"2.8 million households, with a population of about 15 million!" Li Shimin gave an accurate figure.

"How many people were there during the Great Cause?" Li Yuanjing was stunned, and immediately remembered another special group of people in this period, the hidden family!

"In the five years of the great cause, there are nearly 50 million people and 8.9 million households!" Fang Xuanling responded closely.

Where did the few go? Can just a few decades of war reduce the population by 80%? No one would believe it.

Whether it was the eight-year War of Resistance or the more than ten years of the War of Resistance, although there were many war losses in China, there was no avalanche of the total population.

And a phenomenon that did not occur under such difficult conditions, can it happen now?

Of course, it can't, some of the small eighty percent of the population really died from various natural and man-made disasters, and some of them fled to other places to seek a way to survive, but more people chose to go incognito and become recluse.

"What is the number of people in the class?" Li Yuanjing thought for a while and asked.

"Probably nearly two and a half million people!" Fang Xuanling followed closely in response.

"Two and a half million people support the entire imperial court, no wonder the imperial court is so poor!" Li Yuanjing couldn't help but bury his sentence, you can imagine how hard these people who need to pay taxes are.

"The life of the hermit is more comfortable than that of the people of the Tang Dynasty, even if the main family collects more than the imperial court, it is worth it, at least there is no need to serve labor, and only the main family is responsible."

"If you don't be sarcastic, you won't feel comfortable in your heart, will you?" Li Shimin looked at Li Yuanjing angrily, do you want so many hermits? Of course I don't want to, but what can I do?

"Not really!" Li Yuanjing shook his head with a smile, the way to deal with the hidden household is actually very simple, the premise is to find the right direction.

"There are only more than 2 million households in the entire Tang Dynasty, but even so, each household cannot be granted enough land, which shows that the situation of land annexation is not optimistic, and if the imperial court does not pay attention to it, I am afraid that the number of students will continue to decrease in the future.

So, the first thing to do next is to force these hermits out......"

(The data on the number of households are referred to in the General Dictionary 7 and the Book of Sui, volume 29, and the number of households in the data is reduced according to the timeline of the fifth year of Zhenguan, so as to be closer to the actual situation.) ）
