Settle Down In Tang Dynasty

Double happiness!

If it wasn't already late, and now out of the city, when it was dark, Xue Lang really wanted to see it. Seeing his expression, Princess Pingyang couldn't understand his thoughts. She said with a smile, "samples are sent from both places. Youyang and I will go to have a look."

"Well, let's go!"

In fact, Xue Xinglang's elegant smile was the same as that of xuexinglang.

She followed Princess Pingyang to her study. Beside her desk, there were several pieces of paper that had not been cut. They were very large. Bamboo paper is known only by its color. In this age of no bleach, bamboo paper naturally turns yellow.

Xue Lang several steps past, picked up the paper to have a look, sent a total of five, may be due to different material ratio, each paper texture is not the same.

Xue Lang has studied painting for more than ten years. He knows paper very well and knows what kind of paper is suitable for. Hua Hua flipped through the five pieces of paper and picked out one: "this is the softest one. Look at the other paper is different from this one. The masters should have found the reason and asked them to make it softer."

Princess Pingyang did not understand: "this one can neither write nor paint. The most useless one is it. Why should it be made softer?"

as pretty as a flower, asked by distinguished air of elegance and coquetry, how did he say that he was going to make toilet paper? You can only pretend to be mysterious: "you will know when you do it!"

Princess Pingyang picked up her eyebrows. She didn't mean to see Xue Lang, and she didn't ask any more questions. She just asked people to write it down. Xue Lang was relieved. Since the toilet paper he carried was used up, he was reluctant to use cloth. He bought the cheapest kind of paper. When he used it, he sprinkled a little water on it to make the paper soft. Summer is OK, winter use up, that feeling is simply sour and refreshing can not be described.

The remaining four, picked a pick, Xue Lang pulled out one: "Jianling, you try!"

Pingyang Princess nodded, Kwai snow immediately approached the paper, turned out the paper knife, quickly cut the paper quickly, and the paper was cut out. The snow had already worn away the ink. The princess of Pingyang took a brush, slightly swore, stained with ink and began writing on paper.

was only seven days after spring, and had been away from home for two years.

After returning to the wild geese, I think of hair in front of flowers.

The characters of Princess Pingyang are very good. They are not only elegant and graceful, but also graceful and graceful. In modern times, she must be a great calligrapher.

I read it a few days ago. It was Xue Daoheng's poem. Xue Lang learned how to draw. Naturally, he understood Chinese characters. His eyes were shining. He said in a hurry: "send me this word! It's a wonderful writing

Princess Pingyang was speechless, and chuxue chuckled, which was also the same smile. Xue Lang responded to it --

he was anxious to see whether there was scattered ink on the paper. He was embarrassed to be laughed at. When the ink was dried, she took it up and said, "it's OK. Calligraphy and painting are naturally the best Xuan paper. Xuan paper should be made of sandalwood and straw. Bamboo is not good It's enough for ordinary writing and printing! "

Princess Pingyang took a look, nodded and said, "then make paper according to this formula."

Xue Lang nodded and took out his pen. He took a piece of paper and wrote down his name. He said, "this kind of paper can be used for pen writing. It's very good. Let's follow this one."

Princess Pingyang nodded and looked at the first snow, which immediately wrote down. After choosing the paper, Princess Pingyang asked people to take silk cloth. She was sent three pieces in blue, pink and dark red, all with patterns, which were very beautiful.

Xue Lang took it over to have a look and felt it. Princess Pingyang said, "blending has your guidance. In fact, it's not difficult. The difficult one is dyeing. It's really difficult to dye evenly and look good. Fortunately, after studying for many days, it's finally done! "

Xue Lang nodded. He didn't understand the dyeing problem. When he went to the weaving workshop, a master asked him about it. Xue Lang could not help him. The masters had to explore by themselves. Otherwise, it would not take so long.

Which color do you think is good

Asked Princess Pingyang. Xue Lang looked at the princess Pingyang, then at the cloth. Without hesitation, he pointed to the dark red one: "this one is beautiful! On the Dragon Boat Festival, there will be a banquet in the palace of saints. Jianling, if you wear a skirt, it will be amazing. It will also be a big advertisement. When the cloth comes out, it will sell well! "

"Cough, cough, cough!"

The first snow seemed to be choked by saliva and coughed several times. Princess Pingyang looked at him like a smile. Xue Lang was puzzled and asked carefully, "where am I wrong?"

Princess Pingyang glared at him and said calmly, "nothing! It's good. "

Xue Lang nodded at ease and said, "I'll go back and write a sales plan for you. It's almost the Dragon Boat Festival. You can have a wave of sales promotion. After you open the market, you won't be afraid of it!"

"Goodness! So please Youyang. "

"Well, just give it to me."

With that, he patted his chest with satisfaction. Pingyang Princess smile, unexpectedly inexplicably feel Xue Lang a bit cute, but also no longer care about his low EQ and no interest.After a little meditation, Princess Pingyang suddenly said, "Youyang, can you write a mathematical book?"

"Well?"

Xue Lang Leng Leng Leng, pointing to his nose, not sure asked: "I write?"

Princess Pingyang nodded: "yes

Xue Lang was a little hesitant and not very confident. During these days, she often read books in her spare time. Princess Pingyang often sent books to him. Knowing that he was proficient in mathematics, she found the ten classics of mathematics and sent them to him.

In the Tang Dynasty, Guozijian set up the subject of mathematics, which was the ten classics of mathematics. The ten classics of numerology include the earliest ten editions of Zhoubi Suan Jing, Jiu Zhang Suan Jing, Dao Dao Suan Jing, Wu Cao Suan Jing, Sun Tzu Suan Jing, Xia Hou Yang Suan Jing, Zhang Qiu Jian Suan Jing, Wu Jing Suan Jing, Ji Gu Suan Jing, and Jie Shu.

The study of mathematics and geometry in the "ten classics of mathematics" has been quite advanced and profound, leading many other times in other parts of the world at the same time. It involves calculation methods such as numerator, denominator, square root, open cube, positive and negative numbers, equation, etc. the concepts and mathematical names involved have been used till later generations.

Xue Lang doesn't specialize in mathematics. His degree of study is I guess it's similar to the ten classics of mathematics. He can't write calculus. He's only a little proficient in it. I can't understand it. Write a Book Do you think it's a good idea to be a good teacher?

Xue Lang is not confident!

After he said these worries, Princess Pingyang said angrily: "confused! Youyang used to have foresight. Why is he so short-sighted in this matter? "

Is it of great significance to write a mathematical book?

Xue Lang said that the brain circuit is different, completely does not understand, simply arched his hand: "please your highness to point out!"
