"The grass is like a cocoon, and the silk in the cocoon is like a fine thread, and it is called a white stack."

"Smack!"

There was a soft sound, but it was the book in Liu Yiyi's hand that fell on the table, looking at the name on the cover of the book cover, it was the "Book of Liang" that had just been compiled the year before last. A page from the Biography of Gao Chang.

"It is like a cocoon, the silk in the cocoon is like a fine silk, called white stacks, and the Chinese people take the weaving as cloth. The cloth is very soft and white, and it is used in the market. Unconvinced, Liu Yiyi read it softly again, and his face gradually showed ecstasy. At the same time, there are some disbelief, how can this plant already exist in the Tang Dynasty?

Well, according to this "Book of Liang", isn't this kind of plant called Bai Diezi already planted by the Gaochang people before the Sui and Tang dynasties?

Unexpected, yet infinitely surprising. Unexpectedly, when he was bored at home and casually flipping through history books, he could make such a big discovery.

White stacks, white as a cocoon, silk like fine silk, isn't it the ancient name of cotton once said by an old-fashioned professor of agriculture?

Cotton, white stacks, willow in the mind of some due to the passage of time, has been a little forgotten vague memories flooded again, a preference for ancient history of the old man surnamed Li, from time to time will froth in the classroom, very off-topic talk about the brief history of various agricultural things, the ancient name of crops, the origin of crops, the role of crops, there are countless things, because they are not very important, and will not be used as an exam question, most of them have not remembered much, the only thing that I remember clearly is that in this old man's class, it will always make people drowsy.

The fruit is like a silkworm cocoon, and there are filaments in the cocoon, plus what the old man said, in addition to cotton, will this be another thing?

Liu Yiyi couldn't help but feel a little regretful in his heart, why he didn't listen carefully in Old Man Li's class at the beginning, and missed a lot of things that are very important to him now, so that he was not able to discover this 'secret' until now, and only now did he know that as early as the Tang Dynasty, there were already records about cotton as a crop, and there was such a thing as cotton.

"Husband, what's wrong?" Seeing that her husband was facing a book, she was happy and worried, Zhang Chuchu didn't let go of it, so she came over with a cup of tea, and asked softly.

"Hehe, it's nothing, I just remembered some of the past," he stretched out his hand to take the tea bowl handed by Chu Chu, handed it to his lips and sipped it lightly, Liu Yiyi smiled and pointed to the "Book of Liang" on the table, and said to Zhang Chuchu in a loud voice: "Lady, please look, my husband found an interesting thing in this book." ”

"Oh? What could make her husband so happy? Curiously following what his husband pointed out, Zhang Chuchu also read out the words contained in the book softly and casually: "Gao Changguo, prepare nine grains, and many people eat mutton and beef." Out of good horses, Pu pottery wine, stone salt. There are many plants and trees, the grass is solid like a cocoon, the silk in the cocoon is like a fine silk, it is called a white stack, and the Chinese people take the weaving as a cloth. The cloth is very soft and white, and it is used in the market. ”

"These are mostly Gaochang specialties, and many things are also circulated in the territory, and there are not too many strange things, I don't know what the husband is?" Seeing the things contained in the book, Zhang Chuchu turned his head to look at Liu Yiyi even more strangely. Ma is not as good as Yili, wine is not as good as 'three bowls are not as good as gang', cloth is not as good as silk and silk, and those things of salt and stone are even more ordinary, I don't know why my husband is so interested in them?

"Huh?" This time, it was Liu Yiyi's turn to be surprised, put the tea bowl in his hand, stretched out his hand and pointed to the sentence 'white stack', and asked his daughter-in-law in a loud voice: "This white stack can not only weave silk and silk, but also be a good livelihood, why is there no planting in my Datang country?" ”

Although cotton is not as good as silk, but it is better in terms of output, more in use, since someone can make it into cloth, why is it rare in the market of Datang? I have been in the Tang Dynasty for nearly two years, why haven't I even heard of it?

"These, the concubine knows a little," bent down on her husband's side, Zhang Chuchu carefully replied to her husband: "Although Bai Diezi can also weave silk into cloth, but the cloth is coarse, silk weaving is not easy, most people don't like it, far less than hemp, silkworms are easy to see, it is a domestic farmer, few people are willing to do this hard but no good thing." ”

"Oh, that's right," Ryuchi nodded, and immediately understood the key to this.

To put it bluntly, it is still a problem of technology, although the Tang Dynasty has cotton, but it is suffering from the fact that it can not make good use of the production process of cotton, can not weave decent cloth, can not sell at the right price, so that the cotton cloth woven by the local method is not as good as cotton cloth, lack of economic interests and no one cares.

"Xiaoyi, go to the study and get some pen and ink!" After figuring out a few sections, Liu Yiyi smiled at the corner of his mouth, picked up the tea bowl on the table for a while, and comfortably opened his voice to give an order to Xiao Yi who was waiting on the side, and when Xiao Yi retreated, he turned his head and said softly to his daughter-in-law: "These days, the palace is on vacation, and tomorrow I have time, and my husband wants to go back to the old house of Sanyuan, and the lady and Bao'er will also go with the husband when the time comes." ”

In the past few days, the matter of Quan Wanji will definitely be full of turmoil in the city, and everyone's eyes will inevitably be gathered in one place, the prince kills the teacher, and the king of Qi rebels, no matter from which aspect, it is not a small thing, and it is inevitable to cause a big sensation, and it is inevitable to take advantage of this time to quietly go back to Sanyuan's hometown.

"Really, really, husband?" The voice trembled slightly, Zhang Chuchu's little hand couldn't help but grasp Liu Yiyi's sleeve, his expression was uncontrollable, he had been back to Chang'an for so long, Chu Chu dreamed, and wanted to go back to Sanyuan.

"Sanyuan County, starting in the pre-Qin period, set Menghou Yuan, Fengyuan, Bailuyuan three places and get its name, how is it also a place where a person is outstanding, come to Chang'an, there is no reason not to go to Sanyuan," drank the tea in the bowl, Liu Yiyi patted his daughter-in-law's little hand with his backhand, and said softly: "From the beginning of the year to the present, our family has come to Chang'an, it has been more than half a year. ”

"Husband~!" Zhang Chuchu wrapped his arms around Liu Yiyi's arm, his voice was as tender as water, and the honey in his eyes was infinite.

"Mm-hmm, sir, madam, the pen and ink have arrived." Raised his feet to enter the door, and saw that the old man and wife of their family were tired of kissing each other, hugging each other, looking so ashamed, Xiao Yi blushed and put the pen, ink, paper and inkstone in his hand on the table in front of Liu Yiyi and his wife, and then quietly lowered his head and ink, not daring to raise his head at all.

"Bao'er is still sleeping, and there are people around her, so Xiaoyi should go over and take care of it first." Letting go of the arm holding her husband, Zhang Chuchu raised her hand a little embarrassed to take the stone inkstone in Xiao Yi's hand, blushed, whispered and walked the little girl out of the door, and shyly and infinitely picked up the ink for Liu Yiyi inkstone in person.

"Hehe," looking at his daughter-in-law's shy appearance, Liu Yiyi shook his head and chuckled, got up, grabbed the wolf pen on the table, put some ink on it, and then drew on a blank piece of paper.

In less than a cup of tea, a strange thing in the shape of a crooked bow leaped onto the paper, thick wood, light strings, like a bow and not a bow, and looked at some miscellaneous small bears and wedges interspersed on it, but it looked like a musical instrument with only one string.

"Husband, what is this ......?" Stopping the movement of inkstone in his hand, Zhang Chuchu's gaze stayed on the freshly made drawing paper of Liu Yiyi, his face was unfamiliar, and he didn't know what the painting was.

"Slinging the cotton bow!" Without answering his daughter-in-law's question, Liu Yiyi turned his head and smiled at Chu Chu, and wrote three neat Song characters in the lower right corner of the drawing.

The cotton bow, in the thirteenth and fourteenth centuries AD, is the most popular and commonly used cotton processing tool, which is often seen in modern China and among the rural people. In the agricultural college where Liu Ichijo studied, the most primitive cotton playing tools, such as the cotton bow, are also collected and displayed, so Liu Ichichi is no stranger to it.

"Slinging a cotton bow?" Zhang Chuchu asked softly, "I don't know why?" ”

"The secret of heaven must not be revealed," drying the drawn drawings and putting them aside, Liu Yiyi sold an official: "The lady will know in the future." ”

After that, Liu Yiyi picked up the pen and poured some ink, and one after another, he drew three more drawings, and Zhang Chuchu watched carefully from the side, which were for the three things of 'spinning wheel', 'loom', and 'churning car'. It's very unfamiliar, but it seems that these four things seem to be somewhat related, and I wanted to ask about the actions of these things, but seeing that the husband seemed to be tired, he didn't plan to explain more, so he had to give up for the time being, carefully stacked the four drawings and prepared them, and didn't say more.

"The lady will go and clean up first," Liu Yi sat down at the table slowly, and said to his daughter-in-law: "Let's set off early tomorrow morning, and remember to bring these four drawings when the time comes, and they will be reused for the husband." ”

"Well, there is," after a pause, as soon as the temperature tea was at the entrance, Liu Yiyi said again: "This trip, there is no need for Yahuan to accompany you, let Xiaoyi stay at home and guard the door, if it is not bad as expected by the husband, in these days, there are not a few guests who come and go, and there are indispensable people in the house to take care of it." ”

"Well, the husband is right, the concubine will go to prepare and explain!" With a light response, Zhang Chuchu finished packing up the four pictures that Liu Yiyi had just made, took them and entered the inner bedroom.

When I go home, I can't walk through the streets and visit relatives and friends openly, but it's good to be able to see it from such a distance. From last year to the present, it has been nearly a year, I don't know the two elders of the family, but now they are still in good health, packing the clothes and luggage for replacement in the room, Zhang Chuchu's expression has always seemed a little trance, and she is timid, this has not yet arrived home, she is already a little uncertain.
