Settled in the Tang Dynasty

Chapter 374
It was double happiness!

If it wasn't for the fact that it was getting late, and he was going out of the city now, and would not be able to enter the city after dark, Xue Lang really wanted to go and have a look.Seeing his expression, Princess Pingyang didn't understand what he was thinking, and said with a smile: "Samples have been sent to both places, Youyang, come with me to have a look!"

"Okay, let's go!"

The two went to the study with great interest——

In fact, it was Xue Lang who was in high spirits. Princess Pingyang was still so elegant and calm, but just looking at Xue Lang's appearance, the smile on her lips was confiscated.

Follow Princess Pingyang to her study. Beside her desk, there are several uncut sheets of paper, which are very large.Just by looking at the color, you can tell it is bamboo paper. In this age without bleach, bamboo paper naturally turns yellow.

Xue Lang went over a few steps, picked up the paper and looked at it. There were five papers in total. It may be because the material ratio is different, and the texture of each paper is different.

Xue Lang has studied painting for more than ten years, and he is very familiar with paper, so he knows which kind of paper is suitable for him.Hua Hua flipped through the five sheets of paper and picked out one: "This one is the softest, and other papers are different from this one. The masters should have found the reason, let them make it softer."

Princess Pingyang was puzzled: "This piece can neither be written nor painted, and it is the most useless one. Why do you need to make it softer?"

Xue Lang blushed when he was asked, and asked him how to say that it was used to make toilet paper to a beautiful woman who was as beautiful as a flower and a jade with a beautiful appearance?He could only pretend to be mysterious and said: "You will know when you make it!"

Princess Pingyang raised her eyebrows, seeing that Xue Lang didn't mean anything, she didn't ask any more questions, and just asked someone to write it down.Xue Lang secretly heaved a sigh of relief. Since the toilet paper he carried was used up, he was reluctant to use cloth, so he bought the cheapest kind of paper. When using it, pour a little water on it to make the paper soft.It's fine in summer, but when used in winter, the feeling is so sour that it's indescribable.

After choosing the remaining four cards, Xue Lang pulled out one: "Jian Ling, try it!"

Princess Pingyang nodded, Mu Xue immediately stepped forward to take the paper, pulled out the paper cutter, and quickly cut out the paper, the paper was cut out, Chuxue had already polished the ink, Princess Pingyang took a brush, and pondered for a while , dipped in ink, and began to write on paper——

It's only seven days since spring, and I've been away from home for two years.

After the people return to the geese, Sifa is in front of the flowers.

Princess Pingyang's handwriting is very good, not only has the unique beauty of women's handwriting, but also does not lose her muscles and bones, and is handsome and handsome. She must be a master of calligraphy in modern times.

I saw the poem when I was studying a few days ago, it is Xue Daoheng's poem.Xue Lang is a student of painting, so he naturally understands characters, and his eyes lit up when he saw it. He hurriedly said: "Give me this character! It's really well written!"

Princess Pingyang was speechless, and Chuxue gave a "puchi" smile, and it was this smile that Xue Lang realized——

If you are in a hurry to appreciate any calligraphy, you must first check whether there is loose ink on the paper. I am embarrassed to be laughed at. After the ink dries, I pick it up and look at it: "It's okay. Of course, calligraphy and painting are best on rice paper. Rice paper should be made of sandalwood and sandalwood." Straw is the best, bamboo is not good, but these bamboo papers are enough for ordinary writing and printing!"

Princess Pingyang took a look at it, nodded and said: "Then follow this recipe to make paper."

Xue Lang nodded, took out his pen, took another piece of paper, tried to write down his name casually, and said: "This kind of paper can also be written with a pen, it's very good, just follow this! "

Princess Pingyang nodded and looked at Chuxue, Chuxue immediately wrote it down.After choosing the paper, Princess Pingyang asked someone to bring silk cotton cloth.A whole three of them were sent to her, blue ones, pink ones, and dark red ones, all of which had patterns and were dyed very beautifully.

Xue Lang took it over and looked at it, then reached out to touch it.Princess Pingyang said: "With your guidance, blending is actually not difficult. The difficult part is dyeing. It is really difficult to dye evenly and beautifully. Fortunately, after many days of research, it is finally done!"

Xue Lang nodded. He didn't understand the problem of dyeing. When he went to the weaving workshop, a master once asked him. Xue Lang couldn't help him. The masters could only figure it out by themselves. time.

"You Yang thinks, which color looks better?"

Princess Pingyang asked.Xue Lang looked at Princess Pingyang, then at the cloth, and pointed to the dark red one without hesitation: "This is beautiful! When the Dragon Boat Festival comes, there will be a banquet in the Saint's Palace. Jianling, you can make a dress and wear it. It will definitely be amazing." , is also a big advertisement, when the cloth is launched, it will definitely sell well!"

"Cough, cough, cough!"

Chuxue seemed to be choking on saliva and coughed several times.Princess Pingyang looked at him with a smile that was not a smile, Xue Lang couldn't understand it, and asked cautiously: "Where did I say something wrong?"

Princess Pingyang glanced at him and said calmly: "Nothing! It's good."

Xue Lang nodded reassuringly, and said, "I'll go back and write a sales plan for you. It's just around the time of the Dragon Boat Festival, and we can have a wave of promotions. You won't be afraid after the market opens up!"

"Great kindness! So please, Youyang."

"Well, just leave it to me!"

As he spoke, he patted his chest quite smugly.Princess Pingyang smiled, unexpectedly felt that Xue Lang was somewhat cute, but she no longer cared about his low EQ and lack of interest.

After pondering for a while, Princess Pingyang suddenly said: "Youyang, can you write a book on mathematics?"

"Well?"

Xue Lang was stunned for a moment, pointed to his nose, and asked uncertainly: "I write?"

Princess Pingyang nodded: "Exactly!"

Xue Lang was a little hesitant and not very confident.These days, since time travel, I often read books in my spare time, and Princess Pingyang often finds books to send to him. Knowing that he is proficient in arithmetic, she finds "Ten Classics of Arithmetic" and sends it to him.

The Guozijian of the Tang Dynasty set up a subject of mathematics, and what they studied was the "Ten Classics of Mathematical Sciences". "Ten Classics of Mathematics" includes the earliest "Zhoubi Suanjing", "Nine Chapters of Suanshu", "Sea Island Suanjing", "Five Cao Suanjing", "Sun Tzu Suanjing", "Xia Houyang Suanjing", "Zhang Qiu Suanjing" Jian Suan Jing, "Five Classics of Suan Jing", "Ji Gu Suan Jing", "Zi Shu Shu" ten volumes.

The "Ten Classics of Mathematics" has been quite advanced in the study of mathematics and geometry, leading many other parts of the world at the same time. It involves calculation methods such as numerators, denominators, square root, cubic root, positive and negative numbers, and equations. The concepts and mathematical names involved have also been used in later generations.

Xue Lang doesn't specialize in mathematics, his level of learning... I guess, it's about the same as the "Ten Classics of Mathematics". He can't write about calculus.I can't understand it myself, so I go to write a book... Is it considered to be a trick in the class, making me laugh and generous?
Xue Lang has no confidence!

After he expressed these worries, Princess Pingyang said angrily: "Confused! Youyang used to be quite far-sighted, why is he so short-sighted in this matter?"

Could it be that writing a math book is of great significance?

Xue Lang said that his brain circuits were different, and he couldn't figure it out at all, so he simply cupped his hands: "Please give me your advice, Your Highness!"
