After the spring ploughing, there was a big war, and after the war, the prisoners of war were used to exchange food and equipment with the Tang Dynasty.

After Xia Geng, there will be a big battle, and after the battle, he will still use prisoners of war to exchange food and equipment with Datang.

This has become a kind of norm in Byzantium, and in this normality, they gradually regain lost territory, earn profits, and enjoy it.

And Sun Xiangfu's normal state is to give lectures to the people, in the field, teach everyone to farm, since the end of spring ploughing, the content of his lectures, is no longer simply farming, some can impact the local people's thoughts, often will be mentioned in his teaching.

Moreover, the scope of his lectures is no longer limited to the vicinity of Constantinople, but extends all the way to Northern Europe, so that those regions with more backward civilizations can feel the glory of Han culture.

Advanced civilization always has an irresistible influence on backward civilization, as long as it is an individual, they are willing to live a comfortable life of food and clothing, and the Han culture is attached to this characteristic, so that people can no longer resist it.

For more than a year, more than 2,000 members of the art troupe, divided into dozens of groups, continued to tour in the major cities of the Byzantine Empire, gaining countless fans, many Byzantine people with high comprehension and sensitivity to sound, can use Chinese to shout a few ballads from the Tang Dynasty, which is a kind of progress.

As for places like hospitals, after it was established, it quickly became one of the most sacred places in the local area, and in the early years, merchants on the side of the Byzantine Empire could make a lot of money as long as they could get the Chinese patent pills from the Shanyang Pharmaceutical Factory.

However, when they bring these proprietary Chinese pills back to China, they sell them as if they were commodities, because they do not have the techniques of TCM to diagnose patients, and they do not know how to prescribe medicines according to the patient's symptoms.

Therefore, pills for headaches and colds are sold to almost all people who are not diarrhea or have suffered trauma.

The antidote pill is used on all people who are suspected of being poisoned or have a stomachache.

Many times, usually because of improper medication, and the condition is more serious, people who buy pills to eat, may spend a lot of money, but they also have to buy, because these pills, as long as they are taken correctly, can indeed cure the patient, if you don't take medicine, many people may be directly dragged to death by a small illness.

The existence of the hospital completely subverts the local people's perception of taking medicine to treat diseases, it turns out that there are so many reasons for people to get sick, as long as they take medicine for the symptoms, they can cure most common diseases in just a few days, and even the external injuries of deep visible bones, as well as serious diseases such as broken bones, the hospital can also be cured quickly, which makes them feel magical.

After that, the hospital became an important place to spread Han culture.

Because, if the people want to learn the medical skills of the Tang Dynasty, they must first learn Chinese, Chinese characters, Ivan almost every hospital is equipped with hundreds of staff, called assistance, in fact, they just want to learn some of the medical skills of the Tang Dynasty from the medical officers of the Tang Dynasty, and the traditional Chinese medicine of this era is supported by a set of mysterious Han philosophical theories.

Others, such as commerce and trade, factories, etc., were also influencing the Byzantines quickly and on a large scale, and the units of measurement and weight were soon newly unified by them, and the astronomical calendrical calculations were also made, which would make them less and less hindered to their integration into the Han culture in the future.

Of course, at the end of the eighteenth year of Zhenguan, the question of returning had to be raised by Sun Xiangfu.

In Heraclius's view, the visit of the Tang Dynasty mission in this round is positive and vital for them, without the support of the Tang Dynasty, they could not quickly recover the lost territory after the defeat, and improve the domestic productivity, so he led all the ministers and people of the Byzantine Empire to retain Sun Xiangfu.

In the case of their great intentions, Sun Xiangfu finally decided to stay for half a year, and in the summer of the nineteenth year of Zhenguan, he got up and returned to Broken Leaf City in the territory of Datang.

Here, now is no longer the border town area of the Tang Dynasty, thousands of miles to the west, are the territory under the rule of the Tang Dynasty, because Li Shimin has been working here for a long time, so, this city, has not stopped the construction of infrastructure, now, is already a Chang'an a few years ago, or Jiangling as big as the Tongdu Dayi.

In the crowd of people greeted outside the city gate, Sun Xiangfu saw Yu Xiu'er at a glance, singing can really delay people's aging, Yu Xiu'er is in her thirties, and she still looks like a little girl in her twenties, of course, in this era, only Sun Xiangfu treats women over twenty years old as little girls.

Sun Jing is an adult this year, and he is thicker than Sun Xiangfu, and the sixteen-year-old Sun Feng is also like an adult, standing behind Chun Tao, Sun Xiangfu doesn't know why the eldest daughter Sun Wanting is a little dodgy when she sees her eyes, but she still reaches out and pinchs her little face, saying that the eighteenth female college has changed, and the second daughter Sun Wanyu has not changed much, her cheeks still look a little like Sun Xiangfu, seeing her, Sun Xiangfu's mood will be much better.

"Husband, Your Majesty is waiting at the gate of the city, if you want to talk about the old days, you will talk about it when you go home, you are not allowed to drink and feast in the palace today, and the family banquet is prepared at home." Yu Xiu'er saw that Sun Xiangfu wanted to get close to every child, and reminded him.

Not to mention, Sun Xiangfu was reminded by Yu Xiu'er that he realized that he had so many children, and it was estimated that a quarter of an hour had passed if he said hello and chatted a few words one by one, so he waved his hand at many concubines and children, "Go back first!" I'll be back later. ”

Then, Sun Xiangfu broke his promise.

How could Li Shimin simply let him go back, for the situation in Byzantium and the follow-up plan for the big food, at the beginning of the conversation, it was not a matter of a few words, and it could be finished.

"I originally thought that after laying more territory and no external troubles, life would be easier, but I didn't expect that the more I got to the last step, the more pressure became, and Zhengming could have a way to solve the worries in my heart?" After talking about business, Li Shimin asked.

Sun Xiangfu replied, "The difficulty of governance will increase with the increase of territory and the increase of the population under the rule, and it will become larger and larger, so for a long time in the future, we must be in a state of upgrading the political system, respect the customs of various ethnic groups, and formulate different relevant systems according to different regions, which is very necessary."

As the country enters a period of stability, the population will continue to grow, and the pot will be so big, but there are more and more people eating in this pot, and if you don't manage it carefully, there will be problems as the days go by.

Like farming, we should change the state management from shallow and extensive cultivation to intensive cultivation, divide the administrative area into smaller areas, manage more comprehensively, link the degree of regional development with the speed of population growth, reserve land, reserve minerals, and forest resources, all make it clear, and make timely adjustments when there is a situation where per capita land, income, and imbalance and local resources do not have sustainable development, so that it may be better. ”

"The administrative area is smaller, and the management is more detailed." Li Shimin accurately captured the central idea of Sun Xiangfu's words, and after taking out this sentence and repeating it, he felt that it made sense.

As for how to make your own things clear, the relationship between consumption and output, and the follow-up reserves, so that all aspects of the industry can continue for a long time, this is also a university question, when the data of all aspects are really counted, so that the supply layer of the whole country, when there is no break, then the development of the whole country will be stable.

This is some of the later generations of management science, in this period, can take into account this aspect of the very few people, ancient society, often because there is no such planning, a dynasty, in the middle and late period, land annexation will become more and more serious, population multiplication and expansion, resulting in the common people do not have enough to feed their own arable land, and then there is a little famine, when everyone has no food to eat, it is strange not to rebel to death.

"Do you have any specific thoughts?" Although it was not early, Li Shimin, who felt that he had gained a lot from the conversation with Sun Xiangfu, continued to ask.

Sun Xiangfu almost didn't think much about it, so he replied, "It would be more appropriate to divide the state roads into provinces according to certain regional customs and population numbers, and let the government affairs hall manage the affairs of each province in detail."

As far as the state roads we set up at present are concerned, most of them can be divided into three or four provinces, with an average of five or six states, which can be divided into one province, and the whole country can be divided into nearly 100 provinces.

In addition, the political hall and the ten departments should also be expanded, left and right servants and a few flat affairs, to manage such a large area of the country, just to go through all aspects of the data, it will take ten days and half a month, do you think this management, can it be efficient? ”

Sun Xiangfu said this, Li Shimin also nodded again and again, Li Chengqian had complained to him more than once, the country is too big, government affairs are too busy, the current territory of the Tang Dynasty is several times larger than the first year of Zhenguan, and the population has reached more than 110 million, just to read the list of more than 800 states to you, it will take more than half an hour.

It often takes more than a year for officials in the Ministry of Officials to hand over the performance appraisal reports of the county ordinances of more than 5,000 counties, and other departments such as the Ministry of Households, the Ministry of Finance, and so on are all like this.

If the original official system is still adopted, it will never be feasible.

"Zhengming thinks that how should it be reformed?" Regarding the major reform of the entire imperial court system, it is not a trivial matter, Li Shimin asked very cautiously.

Sun Xiangfu thought for a while and said, "Actually, it's not difficult, like the Pingzhang matter of the Political Affairs Hall, we can get thirty or fifty for him, and there is no need to limit the number of people."

According to the actual needs, five people can meet the needs, appoint five, ten people can meet the needs, appoint ten, or even more.

In this way, it is much better to give all people more upward channels, and to maintain a style of teamwork on big things than to stick to a solidified system and let all people fight for a position because of one position. ”

"Fifty flat chapters?" Li Shimin was frightened by a number that Sun Xiangfu casually said, but after thinking about it carefully, he felt that it seemed to make sense.

The reason why Sun Xiangfu dared to think so much was because he lived in the era of such a system in later generations, at that time, there were at least several ****** in our country, and the number of political commissars was so many that ordinary people could not count them at all, and the deputy ministers of various departments generally had as many as ten or eight, and this was only to manage the territory of our country in later generations.

After the unification of the Eurasian continent, the Tang Dynasty will be several times larger than the territory of our country in later generations, and it is normal for the population to reach one billion and eight billion within one or two hundred years.
