These population migrations in the Tang Dynasty are not these two, just to mix sand with the newly occupied places.

Take the plateau as an example, many of the newly occupied places of the Tang Dynasty are from the former Subi country, and this country has a lot of exchanges with the Central Plains, and there is no great hostility towards the Tang Dynasty that defeated the Tubo people who destroyed them, but in the end, the people here have not accepted the rule of the Han people.

Therefore, in a place like this where the influence of the Han people is very blank, it is inevitable to emigrate to it, otherwise if it is still the same as before, the plateau people are plateau people, then they will never have a sense of belonging to the Han regime.

Not to mention that there are still many occupied places that are the inherent sphere of influence of Tibet, and the people there are all deep-rooted Tubo ethnic groups, if such people do not mix some sand into it and get some Han people, they will not be able to plot rebellion every day and drive the Han people out of the plateau.

Therefore, in addition to sending monks to take the opportunity of promoting Buddhism to positively promote the beauty of the Tang Dynasty and the friendliness of the Han people, the people under the rule of the Tang Dynasty should also migrate in.

Not only the Han Chinese, but also other ethnic groups, such as the sultry people, the Qiang people, and some Turkic people who migrated to Longnan.

The more ethnic groups that migrate, the better the sand will be mixed up, because the more ethnic groups there are, the lower the likelihood of coming together.

As for Wu Yuanqing's fear of causing trouble, the main reason is that in addition to the Han people, sultry, the Qiang and Turkic people are relatively strong, to put it bluntly, their brains are not so sufficient, and they are easy to cause trouble.

Speaking of which, it can support the relocation of people in many places, thanks to the recuperation of Datang since the founding of the People's Republic of China.

If it weren't for the fact that there were not many wars in recent years, the development of various places was very stable, the economy recovered, and the natural disasters were relatively much less than at the end of the Sui Dynasty, so that the people lived a richer life than before, and the population was increasing.

During the five years of Emperor Yang of the Sui Dynasty, the population of the country was more than 8.9 million households, about 46 million people. By the time of the establishment of the Tang Dynasty, during the Wude period, there were only more than two million households. Of course, there must be moisture in this, because there are many fugitives who are not registered in the secluded mountains, and there are also many hidden people in the family, which is to evade taxes.

Therefore, roughly speaking, the population of Wude should be less than 3 million households and more than 10 million people.

After nearly 20 years of development, especially in the past ten years of Zhenguan, the population of Datang has grown considerably.

The population growth at this time was not like the kind of population growth that later generations were affected by family planning.

At this time, there is no entertainment at night, and most of the people still have night blindness, and they can't see things clearly when it's dark, so they don't go out at night.

What can you do if you don't go out, sleep, where can you sleep for so long, of course, you have lived a married life, and there is no contraception, of course, people at this time will not use contraception, everyone knows that spreading branches and leaves is the embodiment of filial piety, haven't you heard, unfilial piety has three no after the greatest, as for saying that you can't afford to raise, who cares so much, and then you will talk about it after birth. And so the children were born one by one.

Think about it, even the emperor is like this, the eldest grandson gave birth to his eldest son Li Chengqian in 619, that is, after the establishment of the Tang Dynasty, and a total of seven children have been born over the years.

Ordinary people will not be worse than the eldest grandson, so over the years, it is absolutely not a problem for each household to have five or six, and then the probability of dying is very high, remove half, and each household will add at least two or three children.

So there is a demographic dividend to enjoy. The so-called "demographic dividend" refers to the fact that a country's working-age population accounts for a large proportion of the total population and has a relatively low dependency rate, which creates favorable demographic conditions for economic development.

Some people may say that in the past 20 years, the children born are still children, how can they be counted in the working population.

This is to say that in ancient times, or in poor families, children at the age of six or seven could be counted as working population.

You must know that at this time, you will get married at the age of twelve or thirteen, and if you have children and become a father, you may have to support the family.

Four or five-year-old children who are still nursing in the future are likely to follow the field to do what they can, and those who have livestock at home may have to mow grass and feed, and it is not uncommon for five or six-year-old children to feed cattle in the countryside.

Some people may say that after 20 years, many people have become old people, and they cannot be counted in the working population. Let's not talk about this problem, let's not talk about the old people of poor families in ancient times as long as they can go to the ground, they will definitely work, just say that the average life expectancy in ancient times was only thirty or forty years old, and we know that there was basically no problem of population aging in ancient times.

In the era when you can call yourself an old man in your thirties, it is pure nonsense to say that you can't do work when you are old, how many such people can there be, only a handful.

Therefore, twenty years of vigorous development have allowed Datang to add a considerable number of laborers. It is with such a demographic dividend, these children who can be counted as working population, can the Tang Dynasty migrate to the grassland and plateau.

People in the hinterland of the Central Plains will not be willing to go to the grasslands and plateaus, but for people in the bitter cold land on the border, they can obtain far more land than in their hometown, and they can also enjoy the generous policy of five years of exemption from taxation and forced labor, and the imperial court also issued a year's rations, which is enough for them to willingly leave their homeland to a strange environment to develop from scratch.

People are cheap when they leave their hometowns?

If life is not easy, it is a cheap life, and you still care about leaving your hometown.

The population of the plateau is not large, and it only occupies more than half of the territory of the original Tibet, and only more than 200,000 migrants on most of the plateau are enough, which is about 50,000 households according to a family of four.

Speaking of the population of the plateau, there is a big joke, the statistics of the Tang Dynasty are calculated according to the approximate strength of Tubo, saying that Tubo has about 300,000 standing troops, according to ten to one, at least 3 million people.

There should be more than 1.5 million people under the rule of the Tang Dynasty, so it is just enough to relocate 500,000 people.

Then many courtiers began to object, saying that the cost of moving 500,000 people was too great and too much.

When Li Chengqian went to the prison and talked to Wu Yuanqing, Wu Yuanqing almost stopped laughing.

Million? Are all the officials of the household department pigs? In the plateau environment of Tibet, can there be so many people in the standard of living of the slave society?

Three million, this Nima is more than the population of the Eastern Turkic Empire that was destroyed by the Tang Dynasty, and the population of the Eastern Turks is less than one million in the end.

Li Shimin, who dared to fight, signed the Weishui Alliance, and dared to go from Goguryeo in the east to the Western Regions in the west, and Tuyuhun surrendered to the Turks.

There are 3 million people in Tibet, and all the surrounding countries must be wiped out.
