After the prosperous Tang Dynasty

Xiao Heng looked at his sister steadily for a while, then smiled and said, "It's nothing."

"En." Xiao Yansui nodded, and could only hope that the environment in the examination room would be a little better.

However, I think that the imperial examinations in the Tang Dynasty are not the same as those of later generations. Although it is said that they answer the questions individually, they should not have the habit of locking people in dark and narrow small single rooms, and neighbors talk to each other. This question doesn't seem to be too difficult. In a relatively relaxed environment, candidates should not be too difficult...

"I have a down jacket - a coat, and someone will bring it to you later." Xiao Yansui said seriously to Xiao Heng, holding her chin.

Let her make clothes by herself, she definitely won't, but after traveling to Xiao's house, the biggest advantage is probably that she doesn't need to do anything herself, just open her mouth and order, and there will naturally be maids and servants to help do it.

For things like down jackets, the basic principle is very simple, that is, because the gas does not have good conductivity to heat, so the air formed in the fluffy down jackets that is not easy to convect is used to isolate the area around the body from the cold air outside. direct convection between them, thereby maintaining warmth around the body.

In fact, if it is double-layer plastic with airtight air or vacuum, it will have a better thermal insulation effect, but it is quite uncomfortable to wear clothes that are completely airtight, unless it is in polar conditions like Antarctica. Under normal circumstances, warm clothes in winter still pay more attention to the dual coordination of warmth, comfort and breathability.

Moreover, compared with other things, the material of down jackets is quite easy to obtain.

In fact, ducks or geese are indispensable in the kitchen every day. In the Zhuangzi outside Chang'an City, there are more poultry such as chickens, ducks and geese. Xiao Yansui said that when she wants fine duck or goose down, someone will naturally carefully Pick out the softest and most delicate parts, and send them to her hands after they are clear and clean.

As for the blueprints for making down jackets, Xiao Yansui is not a tailor, so naturally he doesn't know the specific method of cutting the fabric - anyway, there are ready-made tailors and embroiders.

Xiao Yansui was just gesticulating like that. First, he had to sew out the shape of the clothes with two layers of fine soft cloth. You can refer to the winter padded jacket, but it should be a little looser. The goose down is fully filled. In order to prevent the duck down and goose down from being squeezed together, the soft duck down and goose down in the interlayer must be evenly fixed into large squares with a side length of about three inches to avoid the duck down and goose down in each square. accumulate each other.

Xiao Yansui didn't care about the specific production method, she wanted a final result.

When such a down jacket, which was much lighter than a cotton-padded jacket, came out, Axiu and the others still couldn't believe it. Although the jacket looked thick, it was completely empty in the middle. Those duck and goose down jackets are usually fluffy. It flattens out when you stretch out your hand and press it. Can such a thing really keep warm?

In fact, Xiao Yansui's first reaction to keeping warm was actually warm stickers, compared to down jackets made by those tailors and embroiders who forcibly knew the principle. Heating lunch boxes, etc.

These things are nothing more than self-heating materials, and considering the relative stability of heat release and the consideration of preventing burns, materials with more intense heat release during reaction must be directly rejected.

For example, the most common ones in later generations are to use carbon monoxide and iron to react under high temperature and high pressure to form carbonyl iron oil, and then separate them under low pressure to obtain carbonyl iron powder.Carbonyl iron powder can react with oxygen and moisture in the air, and then continue to release heat during the relatively slow reaction process.

It's a pity that with the counterfeit experimental equipment in Xiao Yansui's hands now, she really can't come up with reliable warm stickers. In contrast, Xiao Yansui actually thinks that if she is not afraid of wanting to go to the toilet all the time during the exam If so, it’s better to drink more hot ginger soup, and then get a bigger teapot that has turned into hot water as a hand warmer, but the hot water in it needs to be changed frequently...

Actually, the down jacket in Xiao Yansui's hand that had just been made not long ago, she originally planned to give it to Xiao Heng on the way to the examination room early in the morning, so that he would not throw it away because he thought it was a bit out of the ordinary. at home.

However, Xiao Yansui also thought about it later, and he didn't know what time Xiao Heng would leave tomorrow morning. Instead of rushing to force him to win the lottery tomorrow morning, it would be better to make an agreement with Xiao Heng in advance tonight.

Whether the down jacket is warm or not, whoever wears it knows. =

Xiao Yansui's words were extremely firm, but Xiao Heng couldn't help laughing, and teased his sister with a light smile, "Why don't I know, when will you still be able to make clothes?"

Saying one thousand to ten thousand, it is better to let him try it directly.

Thinking of this, Xiao Yansui turned her head directly, looked at Axiu and said, "Go and get my down coat."

Axiu was slightly taken aback, "Now?"

Xiao Yansui nodded.

"My servant is going now." Axiu saluted in the direction of Xiao Heng and Xiao Yansui, then turned around and walked out quickly.

--Actually, when it comes to the name of the down coat, the tailors and embroiderers who work according to Xiao Yansui's orders have actually said a few words. It is obviously duck down and goose down, but they want to say it is down.

But, then again, the rich and powerful families have always paid attention to elegance, and the down on the quacking poultry such as chickens, ducks and geese seems to be worse than the word "down". 01:30 .

Seeing Xiao Yansui's reaction, Xiao Heng couldn't help being stunned, and then smiled in surprise: "Liu Niang, you really prepared something for me?"

"En." Xiao Yansui continued to nod, although she still rested her chin on one hand and looked melancholy.

"What is the little girl so worried about?" Xiao Heng rubbed Xiao Yansui's head.

"It's okay." Xiao Yansui waved her hand, "I won't say anything else about the exam tomorrow, just don't freeze and don't get sick."

For other issues, no matter how old they are, Xiao Song still has to worry about them, so she won't worry about them...

The two siblings were half joking and half serious, and after chatting casually for a while, Axiu who brought back the down coat hurriedly appeared at the door of the study.

"Sanlang, Liuniang, the clothes are here."

Xiao Yansui didn't say anything, just stretched out a finger, and pointed in the direction of the clothes drying cage.

Axiu understood what Xiao Yansui meant, and immediately took off the cloth that was wrapped around the down jacket, and then quickly put the clothes on the cage to roast for a while, making sure that the cold air that had just been picked up all the way outside was gone, It was delivered to Xiao Heng.

Xiao Heng stretched out one hand, holding the clothes that looked extraordinarily fluffy and thick, Axiu tried to let go, and after reaching his hand, Xiao Heng couldn't help showing a slightly surprised expression, "So light?"

The usual fur coat worn by the children of the aristocratic family in winter has no other characteristics. It is for warmth and to suppress the wind. Just one word, heavy!

Xiao Yansui rested her chin lazily with one hand. She didn't like to try on clothes and change clothes. However, after all, it was a finished product under her command. Xiao Yansui was quite interested in today's display of results. Directly opened the mouth and urged: "Try it on!"

Tomorrow is the day of the imperial examination, and thanks to Xiao Heng, he has been patiently accompanying Xiao Yansui. After hearing Xiao Yansui's urging, seeing the length and size of the dress, it is slightly shorter than the cloak It was a little late, but his reaction was straightforward, he put his clothes on the outside of his shirt, and then straightened his sleeves and neckline.

In fact, as early as the Zhou Dynasty, there were already people who made feather clothes from the fur and feathers of birds and animals, also known as velvet clothes. Of course, Xiao Yansui didn't know that word at the first time when it was simple, so I asked about it. Only then did Mrs. Pei know.In the Han Dynasty, some people used yak hair to make clothing wadding, but the method of this wadding was somewhat similar to simply using yak hair as a warm item, making it into a sandwich and putting it on the clothes to keep warm. There is still a big difference from the down jacket that people fiddled with under Xiao Yansui's explicit request.

For a native of the Tang Dynasty, even if he was a son of an extraordinary family, down, which is an extraordinarily soft material, is actually rarely used in clothes, especially if it is like Xiao Yansui's request. The fluff is very fluffy.

If the people at that time were allowed to do it directly, Xiao Yansui felt that many people would subconsciously spread the down densely. As everyone knows, the warmth retention effect is actually affected by the fluffy space between the down, not just Just the amount of down...

Watching Xiao Heng put on the down jacket, Xiao Yansui sat beside him and looked at him and said casually, "The size of the clothes should be fine. Those tailors who make clothes for the family know the size when they make winter clothes at the end of September. The above is slightly enlarged according to that."

"You can go out and blow some wind. I think this is warmer than other clothes." Xiao Yansui said sincerely, and then urged: "Don't forget it when you go to the examination room tomorrow morning."

Xiao Heng raised his sleeves, this was the first time he saw such tight sleeves on the outermost clothes, but, as Xiao Yansui said, probably, compared to those who looked at them, they looked more chic Pianpian wide sleeves, the sleeves are closed so tightly to prevent air leakage...

Xiao Heng couldn't help laughing again, and agreed directly, "Okay, don't worry, Liu Niang."

He knew that his younger sister not only focused on many things differently from others, but also had a strong ability to act. Xiao Heng was really not surprised at all. Xiao Yansui made a mess in the yard recently. Things that people can't understand...

"If you agree, I'm relieved." Xiao Yansui still sat lazily on the soft bed and looked at him. Of course, it's already at this time, and it's useless to worry about it. She can't help herself now. The hot material hit Xiao Heng's pocket, "Let's go to Aniang's for dinner later?"

"Okay." Xiao Heng nodded and agreed.

Xiao Yansui stretched out his hand, picked up the book that Xiao Heng had just held in his hand, and handed it to him again, "You continue to read? I'll stay by the side for a while, so I don't need to disturb you."

Xiao Heng smiled and said, "Okay."

He first took off the down coat on his body, and it was really warm as Xiao Yansui said. He stood in the warm room wearing it for a while, and he felt a little hot. The situation in the examination room tomorrow is naturally It's not as good as Xu Guogong's mansion. It's just right to use this down coat to go in.

Axiu hurried up, took the clothes from Xiao Heng's hand, folded them and put them aside.

Xiao Heng straightened his sleeves again, then walked to the bookshelf, took out two books casually, and handed them to Xiao Yansui, "You may like the two books on acrobatics that you dug out a while ago."

The two brothers and sisters exchanged the books in their respective hands. After Xiao Yansui took them over, he simply flipped through them and sent out some introductions of craftsman skills in the background of the Tang Dynasty. His eyes lit up immediately, "Hmm !"

Afterwards, Xiao Heng and Xiao Yansui casually flipped through the books. Either they were speechless or Axiu saw that the sky was almost dark, so they walked out almost silently, reaching out to greet a maid in Xiao Heng's yard, and asked her Go to Mrs. Pei and spread the word that Xiao Heng and Xiao Yansui will go to have dinner later.

After a while, seeing that it was time to eat, A Xiucai reminded softly in a timely manner: "Sanlang, Liu Niang, it looks like the weather is almost here now."

"Oh, yes, I have to go to Aniang's for dinner." Xiao Yansui put down the book, then touched an extremely delicate sandalwood carved bookmark from Xiao Heng's desk case, and put it on the bookmark she had just seen After the number of pages, the two books were put together, without any intention of putting them back on Xiao Heng's bookshelf, and handed them to Axiu to hold them without saying anything, and asked again: "Brother, where are you going?" Are there any books of this type?"

Xiao Heng also put down the scroll in his hand, and said with a smile: "Yes, yes, after you finish reading these two books, come here and get them, how about?"

"Not good," Xiao Yansui looked at him, and suggested calmly and calmly: "On your side, for books similar to these two, after someone copies a copy, send it to me directly!"

"..." Xiao Heng really had no chance to see Xiao Yansui's geese plucking before.

After a while, Xiao Heng couldn't help but laughed dumbly and said, "Alright, I'll do as you said."

Xiao Yansui nodded happily, "Let's go to Aniang's for dinner first! As for these two books, I'll have someone transcribe them later and send them back to you."

"Okay." Xiao Heng didn't argue with her at all.

When it was time to eat, because Xiao Heng was going to take the imperial examination tomorrow, Xiao Hua and Mrs. Pei couldn't help but kept urging, especially since it was snowing today, after dark, it seemed that it was better than during the imperial examination in previous years It's even a little bit colder, and as a parent, naturally, it's a little bit more worrying.

Luoyang City, Zhao Mansion.

The night is getting darker, but there are still snowflakes outside the window.

It was still in that quiet and quiet small Buddhist hall, because Zhao Junzhuo went to Chang'an City, without him coming to sit with Liu Shi for a while every day, Liu Shi spent more time chanting sutras in the Buddhist hall these days some.

Yun Qiao, the servant girl beside Liu, has been with her since the early morning. After a long time, the relationship between master and servant is closer than others, so she couldn't help but say a few more words: "My lady, it's cold these days, you My body is weak, so I should pay more attention...Xiao Langjun is not at home these few days, if I see you like this, I am afraid I will be even more worried."

After hearing this, Mrs. Liu's expression relaxed slightly. After reading a passage, she stopped the prayer beads in her hand one by one, raised her head, looked at the thick night outside the window, and murmured softly: "I don't know how my son is now. It’s good in Chang’an City.”

Yun Qiao supported Liu Shi's arm in a timely manner, and after helping her up from the futon, she smiled and said: "Young Lord has been smart and wise since he was a child, and there is a loyal servant sent by the old Lord to take care of him. The trouble is, it's you, my lady, the more you are away from home these few days, the more you have to take care of your health, and after the little man is named on the gold list, the lady will still take care of entertaining guests for him!"

Because more than ten years ago, when her daughter Zhao Concubine died, Liu's life became lifeless, that is to say, there was Zhao Junzhuo to support her, and her life was bought by her daughter, so Liu's Hold on all the time.

No matter how painful and desperate she was, she had to live well, otherwise, she would have no face to see her daughter underground...

However, no matter how unforgettable the memory, as time goes by, it will gradually fade away.

Now, when Liu saw her daughter died, all that was left in her bony body was her hatred for the Zhao family and her despair at her death...

However, when Concubine Zhao died, those who really deserved to die in the Zhao family were all buried with her. Mrs. Liu didn't even know who to hate, she was numb and numb. In addition to still thinking about Zhao Junzhuo, her heart has long since died along with her daughter.

The death of Concubine Zhao left a scar in the hearts of Mrs. Liu and Zhao Junzhuo. The long years covered everything up to be calm on the surface, as if nothing had happened. Even Zhao Concubine's appearance before she was alive became unclear. , it seemed to gradually become a mark representing the past, but the pain that could not be extricated from it was still there.

Yun Qiao softly persuaded: "Mother and child are heart-to-heart, my lady, you are thinking about Xiao Langjun here, and Xiao Langjun is in Chang'an City at the moment, and I must not be able to help but miss your body. It is because of Xiao Langjun , you have to take care of yourself too."

Liu Shi was startled, and nodded.

·

In the early morning of the next day, when it was still daylight, Pei's and Xiao Heng's two places were busy with their own work, and Xiao Yansui was alone in the warm bed, sleeping soundly.

The winter morning was already cold, so Xiao Yansui woke up for a moment. When she turned over, she accidentally stretched out her hand from under the quilt, felt the temperature outside, immediately retracted her hand, and started to sleep again. I closed my eyes again.

My arms seem to be cold, it's still dark outside, and I'm still warming up in the bed for a while, let's take a nap again...

When Xiao Hua went out with Xiao Heng in person, the not too dazzling sun finally climbed up the treetops from the eastern horizon with difficulty.

Xiao Yansui, who had just crawled out of the bed, drooped her eyelids listlessly after changing her clothes. After washing up, she woke up a little bit, and then cheered up, and went out of the yard to head to Pei's side.

After a while, when Xiao Yansui arrived, he saw Mrs. Pei taking a nap on the slum, and suddenly understood, "Aye and brother are gone?"

"Well," Mrs. Pei nodded, beckoned to her daughter, and at the same time ordered the maid beside her: "Let the kitchen get some warm meals for Liu Niang."

Xiao Yansui walked over quickly, and couldn't help but sigh with emotion: "It's so early."

Crawling out of bed when the weather is so cold requires more than perseverance. Xiao Yansui feels that this kind of energy can almost keep up with the train home at three or four in the morning during the Spring Festival travel season.

Mrs. Pei casually smiled, in fact, she couldn't help being a little worried, but she didn't show it.

Lovingly hugging the little daughter in her arms, Mrs. Pei gently smoothed her hair and clothes, and said with a soft smile: "Don't talk about them, Liu Niang, you just woke up, wait a minute now Mom, use some food here."

"Yes," Xiao Yansui nodded in agreement.

Pei said again: "At noon today, both father and son will not be able to come back. If Liu Niang is fine, let's stay here with A Niang today!"

"Okay." Xiao Yansui naturally has no objection. She feels that the current state of the Pei family can be brought into future generations when the college entrance examination, parents who may suffer more than the examinees, as for the father Xiao Hua?That father simply went to accompany the exam...

Xiao Yansui could imagine Pei's absent-mindedness and worry at the moment, as well as the faint anxiety that had never been revealed, so she was naturally willing to say a few more words with her here, so as to distract her.

Pei's situation is just a microcosm of many parents and elders who are worried at home, but in the examination room, the state of the candidates is a little different.

The examiner is Li Linfu, regardless of what he thinks in his heart, at least on the bright side, not only will he not embarrass Xiao Heng, but he even specially arranged for him a place where the sun can be directly exposed to the sun, which shows how much he cares about the Xiao family. The care and dedication of this eldest grandson.

After all, the temperature in the examination room was just like this. Whether there was sunlight or not, the difference would be huge.

Xiao Heng was quite at ease, but the person opposite him, who happened to be able to meet his eyes, happened to be Zhao Junzhuo.

The two of them only met each other when they sat down for the first time, and they looked at each other. Then, they nodded slightly as a signal, and neither of them said a word.

It was still after the exam started, Xiao Heng finished answering a paper in a calm manner, wrapped his head in a warm down coat, and was surprised to find that Zhao Junzhuo passed a cup of hot tea calmly and calmly. He took out the empty paper sitting next to him, and continued writing with his head down.

And beside Zhao Junzhuo, the face of the neighbor seated was flushed, obviously sick...
