Li Na, Mrs. Li's eldest daughter, married Wang Chong's son Wang Hua two years ago, and Wang Hua followed his father Wang Chong to Liaodong the year before last.
As for Li Na, Wang Hua couldn't bear the suffering of his wife in Liaodong, so he kept her in Jinyang. Needless to say, the relationship between the two sisters was that they often talked to each other intimately. Even if Li Xiang's mother didn't tell her, she would take a piece of her.
, to my sister.
And that’s true!
Li Xiang took a piece of soap, got up and walked to the east wing, which was Li Na's room.
However, when Li Xiang came to the middle hall and was still a little far away from the east wing, he saw his fourth brother Li Hui walking in with a young man.
The young man was extremely tall. He was wearing a long gown with narrow sleeves and a moire border. His black hair was tied up and he wore a small silver crown inlaid with jade. He looked as gentle as jade and like a tree planted in the green hills.
Between green water.
Just a startling glance makes people unable to look away.
Li Xiang did not expect that the person he was just thinking about would come to his home.
However, his mother is his biological aunt, so it is not so strange for him to come here, but it is natural!
"Second sister, you're here!" The childish voice of young Li Hui rang out, instantly waking up Li Xiang who was distracted. When she saw Wang Yu walking up to her, she quickly said: "Why is my cousin here?"<
/p>
Wang Yu smiled slightly and said: "Cousin, why do you and I have to be so polite? Sooner or later we will be one family from now on."
As a person of later generations, Wang Yu is very clear about the relationship between aristocratic families. Most of them are marriages, just like the Wang family and the Li family!
My eldest cousin married my cousin Wang Hua two years ago, and my second cousin naturally married me. However, because I am still young, I haven’t decided yet!
Li Xiang on the side was immediately shy when he heard Wang Yu's naked words, but there was still a hint of sweetness in his heart, because Wang Yu's words had already shown his attitude, and he would marry her in the future.
"Second sister, look, this is a gift from my brother-in-law. It's called math exercises!" Li Hui, who is only eight years old this year, held up a booklet and showed off to Li Xiang with excitement.
"Brother Hui, don't talk nonsense!" When Li Xiang heard that his younger brother Li Hui called Wang Yu his brother-in-law, Li Xiang immediately broke his guard, his face instantly turned red, and he scolded in a low voice.
"Sister Xiang'er, Brother Hui didn't talk nonsense, he just told the truth!" After Wang Yu said this, he stood up and walked to Li Xiang, hugged her waist, and clasped her fingers together.
Together.
"Cousin, Brother Hui is here again. It's really inappropriate to be like this." After feeling Wang Yu's breath, Li Xiang's heart was completely confused. He wanted to ask Wang Yu to get up and leave, but for some reason he was reluctant, so he could only act like
Like a poor little white rabbit, waiting to be eaten up by the big bad wolf!
Feeling the trembling on Li Xiang's body, Wang Yu couldn't help but feel distressed. He was really too hasty, and now he scared Xiang'er!
After Wang Yu cursed himself, he slowly let go of Li Xiang and whispered softly: "Sister Xiang'er, you can't be angry. If you want to blame me, I blame you for being too beautiful."
When Li Xiang heard this, his ears turned red instantly.
"Second sister, brother-in-law, what are you doing?" Li Fei asked curiously!
"Nothing!" Li Xiang panicked and pushed Wang Yu away, then glared at him fiercely. His pure and lovely look almost made Wang Yu turn into a hungry wolf!
However, Wang Yu's self-control ability is still very good. After all, he is only ten years old and has not yet opened his mouth.
With the tacit understanding between the two, this matter has finally come to an end.
At this time, Li Xiang looked at the object in Li Fei's hand and saw four big characters of math problems written crookedly on the cover.
"Sister Xiang'er, I came to Li's house before and found that Feidi loves reading and studying arithmetic, so I compiled a number study booklet and gave it to him." Wang Yu explained to Li Xiang.
Wang Yu's explanation was very calm, but he also knew that fortunately this was the Eastern Han Dynasty, and he had not been squeezed by Ti Hai's tactics. If this pamphlet were given to future generations and given to primary school students to learn and use, it is estimated that those primary school students would fight him tooth and nail.
I have all the ideas.
But Li Fei was different. Not only was he not angry, he held up the booklet in his hand, looking left and right, as if he couldn't put it down.
Seeing that her brother was so happy, Li Xiang opened it out of curiosity and immediately looked at it, which immediately made her a little confused.
Who am I?
What am I here for?
I saw it said:
The nature of mathematics!
Addition and subtraction!
Multiplication and division!
Multiplication table!
What are these?
Li Xiang said that she was already well-read, but except for the very similar multiplication tables, she knew nothing else!
"Brother Fei, Sister Xiang'er, don't underestimate this mathematics booklet. If you can learn it, you can become a doctor of mathematics!" Wang Yu said solemnly.
Li Fei's eyes suddenly brightened up when he heard this, and he said sonorously and forcefully: "Brother-in-law, don't worry, I will definitely study hard."
"Well, very good." Wang Yu was very satisfied with his attitude, and it was not in vain that he spent half a night compiling this booklet.
I have to mention here that in the late Eastern Han Dynasty, there was no paper that could be written on.
In fact, during the Western Han Dynasty, the hardworking people had already invented papermaking technology, but the paper at this time could only be regarded as a semi-finished product.
At that time, the working people of ancient China used the best quality silkworm cocoons to weave silk, and the remaining bad cocoons, diseased cocoons, etc. were used to make silk floss using the floc method.
After bleaching the catkins, there will be some residual catkins left on the bamboo mat.
When the wadding is bleached a lot, the remaining wadding on the bamboo mat will accumulate into a layer of fiber sheets, which can be peeled off after drying and can be used for writing.
This is early semi-finished paper!
Moreover, the by-products of this kind of floating flocculation are not large in quantity, have rough texture, high cost, and their popularity is naturally average.
During the Eastern Han Dynasty, when Cai Lun was serving as Shang Fanling in Luoyang, the capital, he often went to the suburbs of Luoyang to collect production materials.
After some hard work, Cai Lun created papermaking technology using bark, hemp heads, rags, and old fishing nets as raw materials, which later spread from the capital Luoyang to other regions.
However, the existence of paper does not make things like bamboo slips completely useless. This is because the bamboo slips themselves have the function of preventing moths.
However, paper itself does not have this function, and some confidential documents cannot be saved using paper.
Therefore, for a long time, paper and bamboo slips were in a parallel state.
Of course, the emergence of this situation is also related to people's cultural concepts. People call being famous in history as being recorded in bamboo.
So at that time, bamboo and silk still had high use value.
However, with the appearance of a person, the Eastern Han Dynasty gradually began to use paper on a large scale and gradually abandoned bamboo slips. This person was Zuo Bo.
Zuo Bo, whose given name was Ziyi, was a native of Donglaiye County. He was studious and good at thinking since he was a child. He was a famous scholar and calligrapher at that time.
In the practice of intensive study of calligraphy, he felt that the quality of Caihou paper (paper made by Cai Lun) could be further improved, so he studied papermaking techniques since the Western Han Dynasty with Mao Hong, a scholar at the time, and summarized Cai Lun's papermaking experience and improved it.
Papermaking technology.
At the same time, using bark, hemp heads, rags, etc. as raw materials and using new techniques, the paper was bright and clean, suitable for writing, and had higher use value. It was very popular among the literati at that time and was called "Zuo Bo Paper". However, it is worth mentioning that this Zuo Bo paper is very expensive!
But even so, there are still some dignitaries flocking to it. Even the calligrapher Cai Yong publicly stated that he would not easily polish his pen unless it was Zuo Bozhi!
It can be said that in the years before the Yellow Turban Uprising, the output and quality of paper had obviously made an extraordinary leap.
However, when the Yellow Turban Uprising actually occurred, paper production suffered a heavy blow. Years of war and population losses caused a reverse flow in writing culture, and bamboo slip writing became mainstream again.
This is because Qingzhou was the hardest hit area by the Yellow Turban Rebellion. Under the local chaos in the past few decades, the local life order has been completely disrupted by the war. The papermaking industry has naturally been interrupted and cannot continue to produce paper.
At that time, Qingzhou was the paper-making center of the Eastern Han Dynasty. When Qingzhou was in chaos, the entire Eastern Han Empire began to lack paper on a large scale. Naturally, it had to pick up bulky bamboo slips and expensive silk again.
The historical process of paper writing was interrupted and even began to be traced back.
In addition, bamboo slips and silk have been used to write court documents and edicts for a long time, so they have not withdrawn from the stage of history and been replaced by paper!
Of course, this is also related to the customary power of the upper class. During the Three Kingdoms period, it was still believed that the most important documents should be cast into bells and tripods, and the second most important documents should be written on bamboo and silk, so that they can be preserved for a long time.
In fact, to put it bluntly, the supply of paper is too small, and the wealthy families do not want paper to flow out on a large scale, because only in this way can they master the classics and control the entire world.
………………
Let’s digress, let’s get back to the topic.
As a son of a noble family, Wang Yu naturally knows the tricks involved, but he cannot break this fig leaf because he knows that once broken, the consequences will not be something he can bear now.
Therefore, even if he knew a higher level of papermaking, he would not choose to release it at this time.
Seeing that Li Xiang was interested in these things, Wang Yu did not hide any secrets, so he pointed out these tips one by one, trying to help Li Xiang understand these things.
Time passes slowly like this!
Unconsciously, nearly a week has passed, and the soap made by Wang Yu has been widely promoted in various parts of Bingzhou due to the spread of the Wang family.
It can be said that in just a few days, Wang Yu earned hundreds of gold.
But soap is just a niche after all. As Jiang Hui said, this thing is not edible. Except for rich people, ordinary people cannot use it at all. The reason why Wang Yu brought it out at this time is to pave the way for something.
.
And this thing is sugar!
The reason why China is famous in the world is not only because of the four great inventions, but also because of other things, which are also the first in the world!
Just like sugar!
It is recognized in the world today that the earliest sugar produced was malt sugar during the Western Zhou Dynasty.
Caramel sugar belongs to starch sugar, so it can also be said that starch sugar has the longest history.
Maltose is a kind of sugar made from rice (starch) and malt through saccharification and boiling. It is viscous and is commonly known as maltose.
Since its creation in the Western Zhou Dynasty, it has been widely spread among the people and widely eaten.
History books from the Western Zhou Dynasty to the Han Dynasty contain records of the consumption and production of malt sugar.
However, the sugar at this time was all red or black sucrose. Although the sweetness was acceptable, the taste was just average. Like the white sugar of later generations, it did not begin to appear until the Tang Dynasty. p>
Moreover, this white sugar was introduced to the Tang Dynasty from India. It is worth mentioning that the white sugar at this time was not very white. It was not until the Ming Dynasty that the Chinese processed it themselves and finally made it into truly white as snow sugar. p>
And this method is... yellow mud water decolorization method.
At this point, China changed from a sugar importing country to an exporting country, not only exporting to Japan, but also exporting to the source of Asan.
Wang Yu believes that as long as white sugar appears in this world, it will definitely be several times more sensational than soap. This is because white sugar can be used as an auxiliary ingredient, and every household cannot live without it!
Even ordinary families will buy some for use. Even just one pound is enough for them to eat for about half a year.
Therefore, sugar can be used in a much wider range than soap!
After thinking this, Wang Yu did not hesitate and asked Zhang Tiankuo to call Wan Sanqian over!
Wan Sanqian on the other side saw Wang Yu summoning him. Although he didn't know the reason, he still followed Zhang Tiankuo to his room!
"Sanqian pays homage to the young master!" Wansanqian bowed his hands and saluted.
"Okay, three thousand, you don't need to be so polite in front of me!" Wang Yu was thinking about the sugar business at this time, so he couldn't care about these false gifts, so he said bluntly: "Three thousand, you have been in my Wang family business for several years.
You are 20 years old, but do you know something about the technology of sugar production?"
"Young Master!" Wan Sanqian said to Wang Yu respectfully: "Young Master, when I first started, I was just an ordinary person. Naturally, I had to participate in the production of sucrose. Although I have not done it myself in recent years, I have not done it myself yet.
Forget!"
"That's very good." Wang Yu suddenly felt happy and nodded with satisfaction. Then he took out the tile pattern he had just drawn and showed it to Wan Sanqian and said, "Three Qian, have you ever seen this?"
Object?"
After hearing this, Wan Sanqian came to Wang Yu and looked at the tile pattern carefully. Even though he was well-informed, he was still confused. He could only say with shame: "Three thousand is naturally well-informed, but today he knows that a leaf is blinding his eyesight."
, I have never seen this thing before!"
Wan Sanqian sighed immediately and asked humbly: "Since the young master took out this thing, do you know its function?"
Wang Yu nodded, and under Wan Sanqian's waiting eyes, he told Wan Sanqian the idea of turning yellow and black brown sugar into white sugar, which made Wan Sanqian become dull.
