The most important tax revenue of the Han treasury is grain.

The country of Nanyue was too far away from Chang'an.

Qian Rujun Rujun's planned rail transit is east-west, not north-south.

Qian Rujun's north-south rail transit is at most connected to adjacent territories.

The original traffic situation in Dahan was not good.

The South Vietnamese State will not build a passage to the Han Dynasty to facilitate the other party's army to visit here.

Therefore, if the grain of South Vietnam is to go up to Chang'an, it may take up to half a year or a year, and the new grain will become the old grain.

For such a long time, the transportation on land was not good, and most of the grain, if it could really be transported, had already entered the stomach of the food deliverer.

Unless the big ship built by Qian Rujun sails to Panyu and uses Qian Rujun's big ship to transport these grains.

For the sake of the stability of this place, and let the Han people exercise the right to rule this place as soon as possible, Qian Rujun had better make this suggestion to the emperor.

It was even proposed to replace the grain received in this place with the grain purchased by Jinmai City.

Let the food of this place be eaten or sold on the spot.

The problem is that most of the grain is very difficult to sell in the south.

The big landlords, who bought the grain, did not need the grain.

The poor need food, but they can't afford it.

The biggest food deficit is in the military.

However, if it is transported by Jinmaicheng, then the transportation cost must be borne by Jinmaicheng.

The imperial court will benefit, but it will not produce a little more food.

So things went back to square one, and most of the grain was eaten by the people who delivered it.

Most of it was left only for a part of the emperor, representing the emperor's rule.

For the emperor, there were too many places for this symbolism, and the national court would lose money.

If this place is the place ruled by the traditional emperor Liu Heng, and it is a place that the orthodox court must recover, Emperor Liu Heng, he will have to recognize it when he touches his nose.

"It seems that this matter really has to be done to show the emperor, so that they know that there is a good mode of transportation, and how much there is to improve the transportation and his grain. ”

For the Han Dynasty, the Kingdom of South Vietnam was just a new land.

Although the place has been attacked, the rule can actually be a real headache.

However, the detailed governance has not yet penetrated into the mainland.

Moreover, the people here obviously do not belong to the Han nationality, although they do not necessarily have a rebellious mentality against the rule of the Han nationality. But it's always a difficulty.

Zhao Tuo actually ruled this place with foreign tribes, but he was more popular.

Qian Rujun didn't think that the officials sent to this place by the Han could be very good.

If there are excellent officials, they will basically be assigned to Guanzhong.

The South Vietnamese can tell from the appearance of the people that the people in this place are particularly short, far from being as tall as in the north.

At this time, the tallness of the north was far taller than later generations imagined.

Perhaps in each dynasty China was actually a different race, but no matter which race it was, it had been integrated by the Han people, and the self-proclaimed Han people were orthodox.

So as long as this person rules in the way of the Great Han, or even continues in the way of the Hundred Schools of Thought, then he will be recognized by this place, and the Great Han will continue to devour the nearby ethnic groups and absorb the nutrients into it. It has also caused the expansion of this nation, and the reason why the Han people are called Huaxia is because he never hesitates to learn the good things of the outside world, and after learning, he can carry forward and become his own things.

In later generations, it began to close the country, which is actually no longer the tradition of the Han people.

It's about starting to get scared about the progress of the world.

In fact, this part of South Vietnam has also begun to absorb the local culture with Han culture, and has developed its own characteristics, but what is really worth learning is actually the food in the folk.

Food is the most acceptable and unacceptable thing for human beings.

In Dahan, the food is often made from local ingredients, and the ingredients of Nanyue are not necessarily available from Dahan.

At least, in this era, it is very difficult to transport lychees.

In this era, in addition to grain, basically all kinds of vegetables and fruits are still relatively regional. Fruits with the same appearance may vary from extremely difficult to extremely tasty.

Moreover, different grains, in different eras, have different evolutions, and there are also processing methods.

What really matters is the method of these dishes.

Cooking methods often use different ingredients to bring out a richer flavor.

If the cooking method is learned by other places, it can often be introduced to different grains and trigger different practices, which can greatly enrich the food and eating methods of the Han Dynasty.

At present, the cooking methods of the Han Dynasty are still relatively monotonous, and the diet in the central water tower area of Chang'an and Jinmaicheng has not yet developed to various places.

One of the most important things is that you don't have access to the most basic ingredients.

The night market is only so delicious, and now there are a large number of oil mills in these two places.

In many places, there are not enough tools, or they have not learned how to make oil extraction tools, and the lack of oil makes it impossible to make many delicious ingredients.

Qian Rujun knows that there is already sesame oil in this era.

But there seems to be no way to find something that can be extracted from other ingredients.

And the tools.

Originally, I thought that as long as it spread, there would be many races.

Later, it was discovered that the official need to receive food is the most important thing for people to grow.

If you plant something else, you will be punished.

The reason why Jinmaicheng is far ahead is because Jinmaicheng does not have this rule.

In Qian Rujun's impression, the people here would flee to the south.

When they defeated South Vietnam, they couldn't completely keep these people, and the war of this era was tantamount to plundering and looting, rather than taking care of the local people.

Therefore, the defeat of a war often causes the movement of people in many failed countries.

They want you not to remember that they are the people of a defeated country.

It's a pity that the Han is very strict about household registration management, and it is useless for all those who flee to the Han, so they can only flee south.

As for the south, it is now being devoured by Qian Rujun's Xuetang Island students.

However, in the south of South Vietnam, there should still be empty land.

Because of Qian Rujun's slow attack, let these people see that Qian Rujun did not intrude on the ordinary people, so this time he fought Nanyue, which was different from the past, and there was no large-scale population flow in this place.

Qian Rujun thought to himself, if these people stayed here, then the race of Guangdong and Guangxi would become shorter at that time.

She has changed history, so will her future change? If she does, then her memory should change with it!

Qian Rujun found that the memories in her mind had not changed.

Could it be that she is traveling through a different dimensional space, and if this is the case, all the changes she has made to Dahan are not very meaningless?

For the spearmen and the army led by Bo Qing, those who stayed and did not flee were the people of the Han Empire.

As for before that, if they can be expelled, they will expel these people who don't look like themselves on the outside, if they can't be expelled, it will take at least a few decades, and slowly they will be able to obtain equal rights, and then with the passage of time, or even the change of dynasty, people's memories will gradually forget that they were once people of different races, unless the appearance leaves them too many traces.

For example, people have blue eyes.

But if you want to let a large number of people in the south integrate into the Han nation, the biggest problem is that the people south of the Yangtze River are basically different ethnic groups from the people in the north.

If the Han Dynasty was under the influence of Qian Rujun and did not have the affairs of the Five Hu and Sixteen Kingdoms, then the great integration caused by Nandu would not have happened.

Maybe Qian Rujun's ancestors would not have developed southward.

If so, then the source of the migration may have to be manpower to get these people to migrate.

Otherwise, this place remains purebred and will be a source of division in the future.

In history, the Han people have been massacred many times, especially during the Wuhu and Sixteen Kingdoms era, and without these massacres, the number of Han people would not have decreased dramatically.

There will be no drastic reduction, and the sooner the population boom may come, when there is not enough farming technology and tools, the lack of food means that people will have to go to war for the right to survive for their children.

Otherwise, only famine awaits them.

In this way, it is actually necessary to emigrate to places outside the core area of the Han Dynasty, improve farming techniques, and get a lot of new food.

Qian Rujun thought of the Han Dynasty at this time, in fact, the population growth rate was very fast, and the population could increase by half to double in 30 years.

People also don't have the concept of birth control.

When you have enough life, how to make people have birth control may become a very difficult thing.

Now there are tens of millions of people, and it may not take 100 years to reach 100 million, which is actually a very scary thing.

But in this case, the population does not need to be controlled in large quantities, but Qian Rujun thought that in the last years of the Manchu Qing Dynasty, it was 100 million compatriots, which had already caused a shortage of food in many places.

It is very important to let the people move outward early, to improve the technology of governance early, so that effective governance can reach farther.

In fact, the food of this era is not really lacking.

The most important thing is the hungry, who do not have access to enough food.

Those who are full have no way to sell their food.

In fact, the most important thing is that there is no way to get food to those who need it in time, because if there is no way to produce enough food, how can he have money to exchange it for more food to get to his place?

Because there is no money to exchange, where there is a surplus of grain production, there will be no flow of grain to that place.

And once there was a famine, the people began to move, and the Han Dynasty could not withstand such a change.

Because the court of the Han Dynasty did not have any surplus grain to distribute to these people, when the new land was cultivated, there would be no grain in the first year.

It is no longer enough to give food to hundreds of officials and soldiers, and it is often necessary to use the name of the emperor to rob and use the rich, and take advantage of the opportunity to exterminate the rich to collect enough food to supplement the shortage.

In fact, they like to kill the rich, in addition to the fact that the rich deserve to die, the main reason is because they are very short of food, and only in this way can they obtain it to maintain the operation of the imperial court.

Speaking of which, the main reason why the imperial court does so little is that the salaries of officials really account for too much food.

But are the salaries of officials really high? In fact, if we make a comparison, we will find that the salaries of hundreds of officials are just enough for them to eat or support their families.

It's not like you can't eat too good things, but it's not as good as those who do well in business in the private sector.

Only people with relatively large official qualities have more than what is required to be fed.

However, these people often have to give money out during certain festivals, so these people's salaries in the court are not his most important expenses, in the court, their most important task is actually to grasp power, and after having power, their salaries are deducted by the emperor, in fact, they all feel that it doesn't matter.

I often see a lot of Internet, saying that the imperial court has withheld your salary for how long and for how long, even decades later, but these magistrates seem to feel that it doesn't matter, because they can do some business outside through the power in their hands, because they are familiar with the people who are officials, so they can get more benefits than ordinary people. It's also easier to make money.

After all, in their time, there is no sense of secrecy, and they are the first to know a lot of news.

For these people who can make money, they know that it is possible to make money by seeking innovation and change.

The person who is most afraid of change is actually the person who is the least able to change at all, because once he changes his money in hand, he will have no money in hand, and his future life will become very miserable, because he has no money to buy enough food, and he cannot cope with any of these changes.

For example, if someone in the family is sick, it is equivalent to a catastrophic change for the family, if it is a child, they may just leave it alone, anyway, they can have children in the future, but in this period of the Han Dynasty, it is not good to worship the elders, but the elders will have some diseases before they die, and there are very few people who can die well, and when the elders are sick, they must spend a lot of resources at home to help him treat the disease.

When he dies, the family must be buried thickly, if there is no way to bury it, it will be considered unfilial piety, but if the burial is thick, it often hollows out a person's family foundation, so whenever someone in the family dies, the family is equivalent to going through a reincarnation.

The upstarts tend to get the most money to spend, but they get more of the right to buy more land. Because when there is no money, giving land is the best way for the imperial court.
