I am engaged in construction in Datang

The two recalled what their sister had said.

During this period, Empress Zhangsun needs to take care of her health and cannot have sex, otherwise the consequences will be serious. Even if she recovers in the future, she still has to wear, that, sheep intestine...

Li Shimin was too ashamed to say it out loud!

I can't have any more children, I need to use contraception.

The child absorbed all the nutrients from the mother, which caused Empress Changsun's health to deteriorate.

There are many more things to pay attention to. The sister-in-law also prescribed some medicine and taught the queen to do yoga and gymnastics. She also said that she wanted to research some special medicine for respiratory diseases.

This time they were returning to the palace with still many bags and luggage. They thought the ox cart from last time could be returned this time, but it followed them back to the palace again today.

"Erlang, the cake and milk tea are really delicious. Let's ask the Shangshi Bureau to teach us how to make them later." My sister-in-law never keeps anything to herself. Seeing that they like them, she gives them the recipe.

"The taste is different after I learned how to make it." Li Shimin said, "I thought the roasted bean curd sticks I ate before were just like that. But after I ate the one made by the farm, I knew what the real roasted bean curd sticks were."

"Then come to the manor to eat from now on. It's close anyway." Empress Chang Sun liked this place.

The people in Zhuangzi are hardworking, clean, energetic and a joy to look at.

My sister-in-law and Li Xiaochun are both very capable young ladies. I can talk to her and they all have management experience.

The main hall.

Li Zhi sat on the threshold in front of the hall holding Si Zi, surrounded by palace maids and eunuchs.

"Your Highness Prince Jin, please come back to your room and rest."

Li Zhi frowned and looked at Sizi in his arms with some disdain: "Sizi is crying and you can't comfort him, so let's wait for Father and Mother to come back."

The eunuch glanced into Li Zhi's arms and saw Sizi sucking his fingers, looking a little more lively and active.

The two hugged each other and waited for a while before Li Shimin and Empress Changsun returned to the palace.

"Aye! Aye!" Li Zhi did not move. He was holding Sizi, who was half a person taller than him.

Empress Changsun felt sorry for Li Zhi's young age and was about to rush to pick up Sizi, but Li Shimin got there first: "Guanyin, you should rest more."

"Zhi Nu, why don't you go to bed yet?" Li Shimin raised his eyebrows.

"Father." Li Zhi was not afraid. He ran to Li Shimin's side and hugged his legs: "Mother is weak. I can only sleep peacefully after you come back."

Upon hearing this, Li Shimin's heart softened. He used his free hand to touch Li Zhi's head and praised him: "Child is pure, kind and filial."

They cuddled together for a while and then rested.

……

The news about the biogas digester spread quickly. Within a dozen days, it had spread to several roads around the pass.

But some people believe it, while others don't.

The situation in the villages in the counties surrounding Yingtian Prefecture was fine. When many people heard that it was created by women, they sent people to learn it without hesitation. But outside of Yingtian Prefecture, people didn't believe it anymore.

Li Yin was aware of this situation, so there were three types of certificates, one for teaching and the other for teaching.

Teams that want to make money will sooner or later move to places where information is lagging behind.

Lantian County, Xiahe Village.

"Head, my wife has some dowry in her hand. She asked me to give it to you." The man handed a string of coins to Zhao Feng and patted him on the shoulder.

"Shuanzi..." Zhao Feng clenched the money in his hand.

"When you have the ability in the future, you must lead the village to make money. You are the head of the village elected by everyone, and we trust you."

Zhao Feng pounded his chest twice: "Don't worry, I have to learn it well even if I have to sacrifice my life."

The imperial court had issued an edict regarding the biogas digester, and smart people had already begun to inquire about the situation. Zhao Feng also inquired about it and confirmed that this was a product of Nuzhuang and could be trusted.

Zhao Feng studied in a private school in the county for two years. Later, he was elected as the head of the village and often went to the county.

He knew what the Nuzhuang was like, so as soon as the imperial edict came down, he came to raise money.

You can learn how to build a biogas digester and after you finish your training you can get a construction certificate which has three different types of certificates written on it.

The first one is cheaper and costs only 300 coins to learn. After completing the course, you will be qualified to manage and repair biogas digesters. Ordinary people are not allowed to touch it as it is dangerous.

This kind of certificate is called a third-category certificate.

The second type requires one coin. After learning, you can lead others to build, but you are not allowed to teach others, for fear that you are not skilled enough and teach wrongly. After learning, other villages can invite you to build biogas pools, but the technical fee for each pool can only be 500 coins. The other daily wages are negotiated by both parties.

This is a second-class certificate.

The third type is a Class A certificate, which costs ten strings of cash. After learning, you can teach others. As long as you guarantee the people you teach and register with the government, you can get a Class A certificate.

Zhao Feng wants to take a class 1 certificate.

With this type of certificate, he can lead villagers to help other people build ponds and teach them how to maintain them.

He believed that even if he charged each person 500 wen as tuition, there would still be people willing to learn from him, and it would also provide more labor.

After all, if you go to school in Zhuangzi, you have to pay for your own food and accommodation, which is a huge expense.

After the man left, several more people came to give Zhao Feng money, and finally he collected about 13 strings of cash, which was enough for him to settle down and learn how to build a biogas digester.

There are many cases similar to Zhao Feng's. Some bolder people directly bring their teams to learn.

After completing their studies and obtaining their certificates, they headed south or north to help people build biogas digesters, and at the same time collect teaching fees for the three types of certificates.

Although the technical fee for each pool is only 500 Wen, the daily wages can be negotiated for a higher amount!

I charge 150 coins a day and help you build a pool. It only takes 10 days to complete. I will also train you someone with a Class certificate, so you don’t have to go out and find someone to do maintenance in the future. It’s so cost-effective.

Not only the people from the village, but also the people from Zhuangzi set out for Nuzhuang. Some aristocratic families also sent people there to learn. One reason was to find out the details of Nuzhuang, and the other was that they also needed to build biogas digesters.

Good things, everyone wants to get them and enjoy them.

Nuzhuang College District.

Now the playground has been completed, and children from the village are competing in running on the track, and trying out the feel of their feet at the same time.

Although the concrete floor was flat, it was still painful when they fell. Fortunately, the children were young and recovered quickly.

Some curious people came over. Some were willing to walk a few laps on the track, while others sat on the big stone steps of the stands, touching the flat and smooth stones under their buttocks, exclaiming in amazement.

There are rooms under the big stone steps, some of which are used to store sports equipment, some are used as changing rooms, and there are also dance rooms, yoga rooms, etc.

Zhao Feng followed the instructions of passers-by and came to this area.

"Brother, where can I sign up to learn how to build a biogas digester?" Zhao Feng saw Wang Dahai smearing white stuff on the wall and felt that he must know the answer.

Wang Dahai stopped the work in his hands. Actually, he didn't need to do these things now, but he just couldn't sit still.

"You want to learn?" He stopped what he was doing, put away his tools, and wiped his hands on his torn clothes: "Come with me, I'll take you there."

The two walked across the playground and came to a room under the opposite large staircase. There was a piece of paper with clear words written on it: Biogas Digest Registration Office.

Several students inside saw Wang Dahai and stood up to pour tea for him.

"Engineer Wang, are you bringing someone to sign up again?" The student approached Zhao Feng and asked, "Brother, what kind of certificate do you want to take?"

"I'll take the first class."

As soon as he finished speaking, everyone around him looked at him.
