Du Shaoqing looked at the furnishings of the veteran’s house and nodded. Although it was not a wealthy family, it was not that the family could not live in the winter.

The veteran looked at Xuanxuan, a little girl who was roasting fire in the princess's arms and said with a smile: "Why let the little lady come out and go out to play with my three girls for a while? The child cannot always roast in winter. If he moves and runs, he will not be cold. The more he moves, the stronger his body will be."

The princess was novel in listening to this concept and looked up at Du Shaoqing. Du Shaoqing nodded: "Okay, listen to Uncle Wu. We are all parents who have never brought children, but we don't have this experience."

As he said that, Du Shaoqing pulled his daughter from his wife's arms. The little girl heard it, but she was unwilling to go out. She said timidly to Du Shaoqing: "Dad, would it be good if you don't go out? It's strong wind outside, will it blow me away?"

The whole room was in an uproar, thinking that this child was so funny, how big the wind could blow people away?

"Don't be afraid, go and play with the sister here and see how they play in winter. Don't you complain all day long that you are ignorant and not fun? There are so many children here now, and you can meet many friends." Du Shaoqing encouraged.

Really? The little girl was half-believing and half-doubted. Soon the third daughter of the veteran soldier's family came out. The child was about seven or eight years old. She came up with a sensible attitude and pulled Du Xuanxuan up.

The veteran reminded: "Sanya, this is the young lady from the eldest son's family, you have to be careful."

"No, they are all children. If you say this, you will be heretics. Sanya should not listen to your father. Just treat it as a little sister and play with it." Du Shaoqing interrupted.

Xiao Xuanxuan wrapped her clothes and went out with her. There were indeed many children in the village. Sanya greeted her and about ten children appeared, ranging from five to twelve years old. Originally, Du Xuanxuan was older than her elder sister in front of Xiao Yizi all day, but when she got here, she became a little girl.

Du Shaoqing looked at the veterans in thin clothes around him and said: "The New Year is coming soon. I'll see you guys, uncles and brothers, and give you some food and drink to celebrate the New Year. If there are any difficulties at home, just tell me."

"The eldest son is kind and righteous. We are the ones who need to take care of our master. Each family has dozens of acres of land and can still live on weekdays. Last time you sent so much money, how could there be any difficulties? Other villages envy us. The matchmakers who said they were close to come to their house to marry their daughter to our village. It's so good." The veteran laughed so hard that he cried.

He asked several friends to deliver the wine and meat distributed to each household. Du Shaoqing started to chat with him and said that he would stay for lunch. Li Chengqian thought that Du Shaoqing was very eloquent, and that he was just a trivial matter of family matters, and you could all have a lot of chatting.

Soon after, the guy Erhu ran in and said to Du Shaoqing with a look of discomfort, "Shopkeeper, I found a problem. It seems that except for Uncle Wu, there are not even a brazier at home. In this cold winter, there are not many clothes to keep warm. If there is no brazier or stove, how can you live?"

Du Shaoqing stood up in surprise and asked in confusion: "What Erhu said is the truth? Why no one has said such an important thing?"

"The eldest son misunderstood. This is not a big deal. Everyone comes through this every year, and they haven't seen anything! Burning charcoal and heating is something that only wealthy families can afford. Can we use that there?"

Well, it was a matter of money for a long time. I think if it weren't for the broken arm veteran who had broken arm, I would probably be reluctant to burn a brazier. At this time, Du Shaoqing discovered that the charcoal in the brazier was also the worst quality.

After walking back and forth in the room for a while, Du Shaoqing looked up at Li Chengqian who was following him and asked, "Do you know coal?"

Li Chengqian shook his head, he knew black charcoal himself, and had never heard of coal.

"It's just a kind of black stone that can be burned, but many of them will be dusty when burned." Du Shaoqing explained.

"But Carbon stone? I have seen it in books, and it seems that there is no need for that thing in the palace." Li Chengqian explained.

This is a veteran said: "We know that the carbonite that the eldest son mentioned is not worth a penny. There are products in the Xishan Lok. We used some when we really couldn't before, but it was easy to get charcoal poison for heating, so no one dared to use it later."

Du Shaoqing's eyes lit up and he exclaimed: "You can burn the kang if you are afraid of poisoning, this is easy to solve."

Everyone was puzzled, only Li Chengqian understood and asked in surprise: "Can you solve the problem of charcoal poison?"

Du Shaoqing smiled mysteriously: "Stay here with me to help for two days, I'll give you a credit."

Li Chengqian was reluctant to ask for help. He came to Du Shaoqing for advice. Although he did not agree, he took the initiative to send me credit. Isn’t this still helping him?

Then Du Shaoqing asked someone to go to the valley to retrieve two trucks of carbonite, that is, coal. This thing should be a small open-pit coal mine in the mountains, and luck could be found near Duling.

At the home of the veteran broke-arm, everyone started to start working on the fire kang according to Du Shaoqing's command. Although everyone was surprised that it was not uncommon to build soil into a bed, what was the aisle left in the middle? Are you not afraid of snakes, rats, insects and ants?

When the kang is covered with thick wooden beds and the kitchen next to it is burned with coal to boil water, and the hot smoke passes through the aisle, and the house with kang is as warm as spring, everyone understands that the eldest son is simply too powerful. Doesn’t this perfectly solve the problem of charcoal poison in heating?

"This is the method. Every household can connect the kang to the bedroom to keep warm. Without buying expensive charcoal, I will pay for the cost of making the kang. Everyone will have a warmth this winter." Du Shaoqing said with a smile.

Everyone said gratefully: "The eldest son has done so much for us, how can you still ask you to pay for us to make a kang? It's all simple things that we can do by ourselves."

Li Chengqian excitedly said goodbye and turned around and left. Du Shaoqing followed and asked, "You are thinking about how to make contributions?"

"Well, I want my father to issue an order to spread the method of the fire kang throughout the Tang Dynasty, so that the people will no longer have to worry about being frozen to death in winter." Li Chengqian said excitedly.

Du Shaoqing nodded and joked: "I thought you would go back and put on the kang for the emperor and the queen as soon as possible to seek credit. In that case, you may not only not get credit, but will be scolded by His Majesty."

Well... Li Chengqian complained: "Am I that bad? After all, he is the prince, and he is holding national affairs in his heart."

"Haha, if it were the former prince, wouldn't it be that way? It was also scolded.

Now you are truly like a prince. Congratulations! You have graduated from the kindergarten affiliated to Yunlai Inn." Du Shaoqing patted Li Chengqian on the shoulder and encouraged him.

The prince looked at Du Shaoqing gratefully and nodded heavily. He had already understood what Du Shaoqing wanted to teach. Of course, he seemed to have ignored the kindergarten meme.

"Haha, your suggestions are also good. After reporting on the state affairs, I will arrange for both my father and mother to go on the kang." The prince smiled and got on the carriage and left quickly.

When Du Shaoqing turned around and returned to the veteran's house, his daughter Xiao Xuanxuan had just come back to play with her friends. In the village for two days, Xiao Xuanxuan seemed to have returned to Luoxia Town, becoming a little girl who likes to run wildly all day long. When she entered the house again, she found that everyone was no longer burning the fire, and the room was already very warm. Her mother, Princess Changle, said that this was a newly prepared kang.

Xiao Xuanxuan pouted and complained, "Dad is so bad. She is warming up in the house with her mother. Let me go outside to play and sweat to keep warm. Humph, I want to tell my grandma and let her vent my anger. Next time I stay in the house and let my dad go outside to play."
