All the infrastructure of Datang is being strengthened rapidly, and the efficiency of manufacturing, production and transportation is getting higher and higher.

From Li Shimin's ascension to the throne in the ninth year of Wude, to the eleventh year of Zhenguan, it has been almost 12 years, this time span, in this era, is almost a generation, and later generations, the implementation of the open policy, our country has spent about 30 years to change the whole country, and realize the transformation from poverty and backwardness to modern industry.

At that time, we had many shortcuts to learn from foreign countries. And now, it is all necessary to rely on their own research to explore and advance, and I don't know how many levels it is slow.

Therefore, although in the eyes of people in this period, the changes in the Tang Dynasty are quite incredible, but in the eyes of later generations like Sun Xiangfu, there are still too many deficiencies.

In February, Sun Xiangfu received the members of the art troupe and all kinds of condolence materials have been assembled, Sun Xiangfu took Yu Xiuer, Li Xiangdie, Yao Hongsleeve three daughters, and the overall plan planned at home during this time, and set off on the road.

And at this time, Ma Zhou, who had collected a circle of accounts in the Western Regions, finally returned to Broken Leaf City.

"Your Majesty, the minister has reached a new repayment agreement with the countries according to the plan, and in three months at most, they will continue to deliver the materials we need here and to Talas City." In the government affairs hall of Shattered Leaf City, Ma Zhou reported to Li Shimin.

"Ma Aiqing has worked hard."

Li Shimin nodded with satisfaction, and said, "Next, we must organize everyone to complete the spring ploughing, so that the grain reserves in the Anxi Dadu Hufu this autumn will be more sufficient."

At the beginning of winter, the production of building materials will begin, and the territory of the surrounding subject kingdoms will be incorporated, and I will build fast and accessible roads as soon as possible in all the newly incorporated territories of my Datang, complete the construction of cities in strategic areas, and expand wherever I want. ”

"The ministers receive orders."

After more than two million young people from the Western Regions countries completed the cement road leading from Broken Leaf City to Guanzhong, Li Shimin did not mean to disband them at all, a large amount of cement, bricks, gravel, and carts transporting these materials were constantly collecting and firing.

The entire organizational management ability and efficiency are tempered in such continuous work, who is called Datang has such financial resources to support so many people who are professionally engaged in such work.

In Chang'an City, Li Chengqian's son Li Heng successfully learned a simple dance and performed it for Li Chengqian, for which Li Chengqian was very happy, so he agreed to Li Heng and took him to the playground outside the palace to play.

In fact, in the harem, there is a special playground, which is completely no less than the children's play facilities of several commercial squares outside the palace, and it is even more advanced and diverse.

But Li Heng prefers to go to the playground outside the palace to play, because there are more children over there, and he likes the lively scene of crowds of people.

So, the father and son, dressed in civilian clothes and with three or five guards, went out into the street.

That's right, today's prince of the prison country doesn't need any support when he goes out, and he doesn't need the escort of the brigade to open the way and empty the scene.

Now, no one would want to assassinate him, and even because of the onlookers, it would cause a siege or inconvenience in a public place.

He has taken the pro-people route to the extreme, and he can often be seen on the streets of Chang'an. Or grab a snack at a roadside stall and listen to the diners tell some folk anecdotes.

Or, ask the people who are transporting their own produce and selling it in the city, how the harvest is, and if there are any difficulties that need to be solved.

Some small people in the market, for the future development of the country, what suggestions and so on, he will listen carefully, and will also go down to various industries from time to time to see their work process, output efficiency, etc.

Li Heng, it was precisely because he ran out with him a few times that he liked the matter of going out of the palace to play.

And Li Chengqian still remembers the painful scene when he was a child and was confined to studying in the palace.

He didn't want his own pain to happen to his son again, and he had proven that it was wrong.

As the prince of a country and the future helmsman, he should be well aware of all walks of life in the people, and know the living conditions, living needs, and market prices of the people.

Today, he encountered a small incident.

The price of grain in Guanzhong, and even across the country, began to rise, although each bucket only fluctuated by one penny, but one stone, that is, the price of ten cents, on average, to each family that grows grain, it is a lot.

Because, most families who make a living from farming will generally plant more than 50 acres, and with the current average yield, each household can have more than 200 stone of surplus grain in one season.

After three or four years, the price of grain finally fluctuated, and it rose, which was a great joy for the people of the peasant gate, and then the people began to inquire why the grain had risen.

Yes, just ask, if it had been ten years ago, the people would have never had such a hobby, and these things were not at all something they could control.

Now it's different, not to mention that food prices fluctuate, that is, vegetables, egg prices temporarily fluctuate slightly, they will inquire clearly, this is why, their own eggs, vegetables, at this time, is it appropriate.

This is a kind of progress of the people, they know how to look at the market, calculate the numbers clearly, and do everything, they need to know why, that is to say, they are gradually getting out of the era of foolish people who are controlled by others.

"His Royal Highness the Prince, the grass people want to ask you something, will the policy in the west continue?" In the seating area for adults to rest next to the playground, a strong man wearing cotton clothes and long sleeves and trousers also came here to play with his three babies.

Don't look at this man dressed very decently, but, from the thick calluses on his arched fingers, Li Chengqian can see at a glance that he is just a farmer around Chang'an City, of course, from an ordinary farmer, can also wear Zhou Zhouzhengzheng's cotton clothes, leather boots, and come to the city to play, it can be seen to what extent the economic level of the people of the Tang Dynasty has reached.

Li Chengqian's accustomed smile raised his hand to signal him to excuse him, and said, "Why are you asking this question?" ”

The man smiled and said, "The grass people listened to the agricultural officer in the civil science class and said that the reason why our Datang's grain has risen is because of a series of major projects in the west of the imperial court, and I came to inquire to you, just to know if the price of grain will continue to rise, if it continues to rise, the grass people will work harder this year, and after going back, they will find a few acres of land in the village and plant grain, anyway, they will come to the village to rush to plant, so that when the autumn harvest comes, the income will be more." ”

Li Chengqian looked at this strong man with interest and said, "If you plant more fields, people will work hard, just plant according to the actual situation of your own ability, you can't ask for money and die!" ”

Hearing this, the man was a little shy and said, "The grass people already had three babies before, and last year they took two more orchid concubines, and in the next season of this year, there will be two more babies to raise, earn a little more, so that they can spend a lot of money, it's okay to be a little tired, anyway, now there are cows, carts, and farm work is not too tired, and a few women in the family can help a little, and it shouldn't be in the way." ”

Hearing this, Li Chengqian said with a smile on his face, "You are a good blessing, but if the price of grain rises, your income will naturally increase. ”

Listening to the meaning of Li Chengqian's words, the man immediately understood, that is to say, the policy in the west will continue, and grain prices will continue to rise.

He is happy, and Li Chengqian is not happy, this may be the scene that Sun Xiangfu mentioned to him in his letter before, everyone is like a dragon! When all the people have their own thinking and know how to do better, the foundation of Datang will be truly stable.

Of course, from this little thing, Li Chengqian saw some other problems, that is, the rapid growth of the population of Datang, in the population structure, the number of children is too much, usually, two or three adults, to feed and take care of four or five children, this will seriously affect their generating power, perhaps, should find a way to solve it.

When Li Heng's children were tired of playing and returned to the palace with him, he had already thought of a prototype, that is, like opening a playground with this playground, which is dedicated to children who are not old enough to enter school, or a place to do simple puzzle games, so that special people can take care of those children, and adults only need to send the children every morning and pick them up at night, which will not affect their farming or work.

He didn't know that his idea was a kind of prototype of the kindergarten in later generations, so when he asked Sun Xiangfu for his letter and sent it to Yunnan, Sun Xiangfu didn't think about it, so he voted in favor, and praised Li Chengqian's idea of discovering and solving social problems is very good, and he should continue to carry it forward.

So, after a little discussion in the court, the plan was approved, and after that, there will be some new buildings in the major cities of the Tang Dynasty, that is, kindergartens.

In late February, the Xuanfu team, who began to enter the snowy plateau, finally felt the beauty of the plateau and how uncomfortable the legendary altitude sickness was.

The feeling of pain from the inside of the head, to the outside, is more uncomfortable than the cold and flu, and in later generations, due to the cars, trains, and airplanes, there are more advanced heating and oxygen supply equipment, and everyone generally does not feel much, most of the time it is necessary to stop the site, and the altitude is not high.

But this period is different, not only can we only rely purely on our own respiratory system to supplement oxygen, but also have to carry out horseback riding, camel riding, or walking physical exercise, in this state of hypoxia, do more oxygen-consuming strenuous exercise, is in the future to sit in a comfortable car, completely incomparable.

And after really embarking on this road, Sun Xiangfu understood better why Xue Rengui was defeated in Dafeichuan in history, even if the soldiers in the Central Plains region were strong, when they arrived here, they would lose more than seventy percent of their combat effectiveness.

Even, if you don't have to fight, there will be people who will continue to fall ill and die, affecting the morale of the army, and in this case, it is strange to be undefeated.

Fortunately, Datang used non-war means to absorb here, otherwise, I really don't know how many lives will be filled here.
