"Being alone in a different world is a stranger, and I miss my relatives every festival."

Today is the Mid-Autumn Festival, and on this day that makes people feel homesick, Yang Yu only left himself a moment to miss and started his busy day.

Outside the gate of the East Palace, a four-wheeled carriage, noble and elegant, the whole body is dark purple and black, it turns out that the whole body of this carriage is made of precious rosewood, the cost is amazing.

Behind the rosewood four-wheeled horse-like bodywork, a pink four-wheeled carriage stopped in front of the gate of the East Palace.

Compared with the carriage made of rosewood, the pink carriage is less domineering but a little more exquisite, and the same thing is that they are all so graceful.

This is Yang Jier's carriage, which was specially built for her by the Ministry of Industry.

I don't know how Yang Ji'er got the news, I know that Yang Yu is going to inspect the resettlement of the displaced people today, and he blocked the door of the East Palace early in the morning, and Yang Yu had no choice but to let her follow.

Dong Yue rode a high-headed horse, his eyes like a falcon patrolling around,

"Driving"

Dong Yue clamped the horse's abdomen, and the war horse began to move forward slowly. The convoy behind began to slowly follow, slowly driving towards the east gate.

At this time, the Mid-Autumn Festival is not an important festival, and the most important festivals here are the Spring Festival and Qingming Festival.

But this year's Mid-Autumn Festival is indeed the most joyful festival of Daxing people, without the trouble of forced labor and taxation, the autumn harvest has already been completed, at this time want to celebrate, there is more comfortable than the festival!

The whole Daxing City is shrouded in a rich festive atmosphere, and there is a lot of laughter.

According to the research of scholars in 2014, the reason why the Mid-Autumn Festival became popular was that it began with the celebration of the people of Daxing.

Yang Ji'er couldn't restrain herself from joy, although no one dared to mess with her in the palace, but the number of times she left the palace was pitiful.

The last time Yang Yu went to Luoyang, he was envious, and this time he finally had the opportunity to go out of the palace, as excited as a caged bird flying into the sky.

Feeling the almost imperceptible shock of the carriage under him, Yang Ji'er blushed with excitement, and urged the coachman to speed up more and more, but this is the inner city of Daxing, where there are many residents, even if the princess urges the coachman, she doesn't dare, in case something happens, it's still herself who is unlucky!

"His Royal Highness has traveled,"

In the past few days, the name of Yang Yu, the acting king, has really spread to the hearts of ordinary people, and just allowing money to serve on behalf of others has made Daxing people very grateful and have onlookers. Almost all sides of the street were filled with crowds of onlookers.

Of course, the strangely shaped four-wheeled carriage also attracted a lot of attention. In the eyes of Daxing citizens, the convoy drove out of Daxing City.

Inside and outside the city are completely two different worlds, the city is full of laughter and festive atmosphere, and the outside of the city is a hot labor scene.

Just a few miles out of the city, you can see the scene in full swing.

Qingzhuang is naturally the main force in this hot spot, although the elderly and children can't do heavy work, they do some light work.

Looking at the official road under the car, Yang Yu was very satisfied, the progress of this project is much faster than in previous years, in previous years, those Daxing citizens had to do this, naturally how to save effort and how to come, all of them are grinding foreign workers.

And these victims are different, they are earning a mouthful of life-saving food, and they don't need to be urged, they are all working very hard.

Looking at the ordinary people sweating like rain on both sides of the official road but smiling on their faces, Yang Yu knew that his efforts were not in vain, and after this hurdle, Daxing will definitely usher in another period of rapid development, and it is not impossible to surpass Luoyang.

Suddenly, there was a noise ahead, and the convoy slowly stopped.

"What's going on?" Yang Yu asked as he stuck his head out of the car window.

"Stupid Yang Yu, it seems that there is a car broken down in front of you and is blocking the road." Yang Ji'er stretched her head out, and almost half of her body had already leaned out of the car.

"His Royal Highness the King of Qiqi, a vehicle pulling bricks in front of you broke down and blocked the road." The guards ran to the front to find out the situation with all their might and came back to report.

Yang Yu nodded, not caring about this trivial matter, and suddenly swept the bricks with his eyes, and his eyes suddenly stared.

He quickly got out of the car and came to the traffic blocking the road, leaned over and picked up a brick, and looked at it carefully, as if he had found a treasure.

"Red bricks?" Yang Yu muttered.

"The color is red, of course it's red bricks, you're so stupid," Yang Ji'er also followed when she saw Yang Yu get out of the car, and a large team of guards hurriedly separated the crowd and kept a safe distance.

"It shouldn't be!" Yang Yu ignored Yang Ji'er and muttered to himself.

Yang Ji'er has been in the deep palace for a long time, and he didn't know that there were no red bricks in the Sui Dynasty, and he had always used green bricks, red bricks were invented by the ancient Romans, and they have not yet been introduced to China.

In the production of red bricks, the bricks are generally burned inside and out with a large fire, and then the fire is extinguished to cool the kiln and the bricks naturally.

At this time, the air circulation in the kiln and the abundance of oxygen form a good oxidation atmosphere, so that the iron element in the brick is oxidized to ferric oxide.

Since ferric oxide is red, it will also be red. This is red brick

If the bricks are burned through, water is continuously poured into the kiln, at this time, due to the high temperature in the kiln, the water will soon become water vapor, which will prevent the circulation of air, so that an oxygen-deficient environment will be formed in the kiln, and the ferric oxide in the bricks will be reduced to ferrous oxide and exist in the bricks. Since ferrous oxide is blue-gray, the brick will be blue-gray. This is the green brick

Compared with green bricks, red bricks are the result of cutting corners, reducing the link of watering, which can save a lot of time and cost, but the quality is almost the same, which is why red bricks slowly replaced green bricks in China.

- Red bricks are cheap.

"Where did this pile of bricks come from?"

Yang Yu took a red brick and walked up to the trembling coachman and asked.

"Spare your life, spare your life! Damn the min, damn the min! ”

When the swarthy coachman heard Yang Yoo's question, he began to intercede for himself.

"This king Yang Yu won't blame you, I just want to know where you got these bricks." Yang Yu shook his head and said with a smile.

"Meet Nioh!" When the swarthy coachman heard Yang Yu's name, he suddenly became excited.

"Nioh," Yang Yu was puzzled.

Under the messy explanation of the coachman, Yang Yu finally understood, it turned out that this time he paid money for servitude and allowed work for relief, so that countless people in Daxing could benefit from their lives, and everyone was very grateful to themselves, thinking that they were benevolent and righteous, and were honored as King Ren.

"Back to Nioh's words, these are waste bricks, my owner has a kiln factory, my young master practiced firing the kiln for the first time a few days ago, but fell asleep, forgot to pour water on the brick kiln, burned the bricks, the bricks turned red, some are still red and half green. The villain was ordered by the young master to go to Daxing to find a buyer to deal with it at a low price. The coachman didn't dare to hide it, and he came to the road of 1510.

Yang Yu suddenly realized that it was a burned brick, and he picked up a few bricks to take a look, and sure enough, the blue and red were very ugly.

Unexpectedly, there is hope for red bricks, of course Yang Yu will not let go, with the secret recipe for making red bricks, mass production of cheap bricks can also be regarded as a merit!

"Go, invite your young master over, this king has something to ask."

The coachman departed with a few guards.

"Yang Yu, let's go! It's dirty here. Yang Ji'er urged.

Yang Jier has been living in the palace, and she loves to be clean, but now the ground is full of soil, and she is very disgusted. So he asked a few guards to put a few bricks together, and stood up.

Yang Yu looked at the bricks on the ground and Yang Ji'er standing on it, and suddenly had an idea, picked up a few bricks, spread them on the ground, and docked with the bricks under Yang Ji'er's feet.

The guards hurriedly grabbed the bricks, this kind of dirty work must not be done by His Royal Highness the Acting King!

According to Yang Yu's instructions, around Yang Ji'er, bricks that were half-green and not red were laid on the ground, forming a brick floor that was a foot wide.

Yang Ji'er's foothold soon became the abbot's place.

"Yang Yu, you are so smart!" Yang Ji'er seemed to forget that she was still calling Yang Yu a fool just now, and in a blink of an eye, she boasted that she was smart.

Yang Ji'er happily jumped on the brick surface, just now there were only a few places to stand on the feet, which really made her very panicked, but now she suddenly has a zhang and a lot of width, and suddenly she is much more comfortable.

Seeing the brick surface on the ground, Yang Yu suddenly fell into a memory, remembering the small village in his previous life, when the village through the project had just been opened, and the cement road had not yet been popularized, so the parents and villagers in his hometown raised money to build a brick road. Wasn't he just as happy as Yang Jier in front of him at that time!

The project of the brick road is simple, as long as there are bricks, the road can be paved, there is no technical content, if it is feasible to build a brick road in Daxing?

Absolutely.
