In the blink of an eye, it was mid-December. The children, who had studied for a whole winter, had mastered the basics. Lin Yan felt that their learning speed was amazing.
As long as it is a new knowledge point, if you talk about it once, they can quickly absorb it and extend it into new ones.
She didn't have to bother to explain in detail. Nowadays, they have undergone transformation, their minds are filled with all kinds of knowledge, and their imagination is rich every day.
I want to use what I have learned to create new things.
What Lin Yan taught was all practical stuff, and the rest was up to them to understand and prove in practice.
"The cold season is about to end in half a month, and the year is about to end. Do you have any plans for next year?"
Hua Min smiled and said: "I haven't thought about it yet. Seeing that you are so happy, do you have a new plan?"
Everyone else looked at Lin Yan. She was indeed different today. She was wearing a snow-white leather coat and her sparse yellow hair was tied up. She looked very energetic.
"Lin Yan, what do you want to do?" Shi Zhi rolled his eyes and asked simply. He felt that Lin Yan had too many ideas and it was too difficult to guess correctly.
Shuisheng raised his head and looked at Lin Yan for a while, feeling that she was about to do something big again.
Ye Cong walked up to her, turned around, and then said, "Lin Yan, you look really good today. I also want to wear beautiful clothes."
"Haha, Ye Cong, you look good too. Your skin is much whiter." Lin Yan laughed. Not to mention, after a cold season, the children's dark skin has become a little whiter.
I don't have to face the scorching sun in the hot season and stay at home without going out, but my skin has become whiter a lot.
"Am I really white? Am I the same as you?" Ye Cong asked.
Lin Yan is the fairest among them. Although she can also tan, she is still young and knows how to protect herself from the sun. She may have eaten well in this cold season and has become fair and chubby. She is the most beautiful little girl in Sunshine City. baby.
Shi Zhi looked at Ye Cong and said directly: "How can you compare with Lin Yan? Look at your hands, then look at Lin Yan's, and you will know the gap."
Ye Cong looked down and immediately became discouraged after the comparison, "We can't compare. We really can't compare."
After everyone laughed, Lan Yue asked, "Lin Yan, what is the plan you just mentioned?"
The others fell silent and stared at Lin Yan.
She said: "You have learned so much, and next year you must put what you have learned into practical use. The reason why I chose you to take the class is because you are smart and can remember everything you learn, but as time goes by, some things will slowly fade away." Forget it, have you ever thought about how to record the knowledge, pass it on, and let more people know it?"
Shi Zhi raised the slate in his hand, "Isn't this a record? My house is full of slates. They are all records I usually make and will not be lost."
Hua Min said: "Although the slate can be used for recording, it is too bulky, and the things written down with charcoal pens will gradually become blurred. I even traced all my notes a few days ago, for fear that the handwriting would become too long. Gone."
"Yes, I also discovered it." Ye Cong hurriedly followed.
Others nodded. The slate record did have many shortcomings. The most feared thing was that it would fade over time and the handwriting would be blurred. If you didn't notice it, you would have to write it again.
They noticed these shortcomings, but did not think of a better way.
They looked at Lin Yan expectantly. Since she said that, there should be something she can do.
Huang Ying couldn't help but said first: "Lin Yan, do you have a better way? Tell me quickly."
"Okay, let's not give in." Lin Yan looked around with a smile. They couldn't help but beat someone. She felt that the time had come.
"Actually, there are many kinds of carriers for recording text."
"Many kinds?" Everyone was surprised. They didn't expect that there were many kinds.
Lin Yan nodded, "There are indeed many kinds, and you will see them later. Let me talk about bamboo slips and paper first. Bamboo slips are bamboo slips made of bamboo, with words engraved on them, and they can be stored for a long time. The disadvantage is It’s heavy, cumbersome to make, and inconvenient to transfer.”
"Where's paper, what is that?" Hua Min was extremely curious. It was the first time she heard about paper, and she could still understand it on the bamboo slips. The way Lin Yan painted it on the stone slab was very vivid.
"Paper is made of various fibers through complex processes. It is light and easy to use. It can be written with a special pen and can be stored for a long time. Binding the paper into a book creates a book. A book can be passed down better."
"What does it look like?" Hua Min became more confused and confused as she listened.
Everyone else also had question marks on their faces and had no idea what Lin Yan was talking about.
Lin Yan felt that he had overestimated them. He had never seen the real thing, and no matter how he described it, it was still very abstract. She made a decision immediately: "Okay, I can't explain it clearly, but I'll understand it when I do it."
"Make it? When will we do it?" Hua Min said eagerly. This is so important, especially since they have learned so much and want to teach more people.
Shuisheng asked: "Do you know how to do it? What should we prepare?"
"I know the general process, but I have never done it before." Lin Yan was also very sorry. Paper has a long history in the history of human civilization, and it became very common in the later period. Who would have thought of doing it personally.
"So, next year we must work together and keep experimenting to make paper. No matter how good the quality is, make it first and then slowly improve it."
"Okay, okay, I'll go with you." Hua Min was very positive. She really wanted to see what the magical paper Lin Yan said looked like.
Shuisheng also said, "Me too."
Others are not to be outdone and are very active in joining.
If paper could be made, it would be a new beginning.
Lin Yan said: "I just need you to do it together. I don't know when I can make it on my own. Not only do I need to make paper, but I also need to make pens. The charcoal pens used now are too thick to write on the paper. No. Therefore, our task next year is not only to make paper, but also to make pens. It is an arduous task."
"With you here, we will definitely be able to do it." Ye Cong admired Lin Yan very much and believed that it would not be a problem with her here.
Hua Min also agreed, "If you know how to do it, we can definitely make it."
"That's right, we already know the general process. If we still can't do it, wouldn't it be useless?" Huang Ying continued.
Bai Chen: "Paper is so easy to use, what materials should we prepare?"
Everyone else stopped and stared at Lin Yan, wishing they could jump into the experiment right away.
"Let's start with the straw paper. This is the simplest. As the name suggests, the straw paper is made of grass. Let's find some more reeds and wild grasses to try. Speaking of the improvement of charcoal, the one burned on the fire is not very easy to use. Mao Mu and Lin Yun, you two have experience in making products, first use the kiln to burn some charcoal, and then we will find ways to improve..."
Everyone else was shocked when they heard that paper was made of wild grass. Can grass make paper?
But seeing Lin Yan's confident look, they suppressed their doubts and continued to listen to Lin Yan's explanation of the principles of papermaking.
