In the end, everyone discussed making a clipboard in the courtyard, and when it was time to prepare the materials, it was better to put it on the top platform of the castle, so that they could stand on it and learn to read while looking around, after all, if everyone stared at the clipboard, regardless of the surrounding situation.

To learn to write, you first need to make a blackboard.

The blackboard is a board, but everyone has a lot of effort. Two days later, some of the wooden boards left over from the building of the house were spliced together to make a writing board, and a long wooden stick was inlaid on each side of the writing board, and a wooden stick was inserted diagonally in the middle of the wooden stick, so that the writing board had four legs and could stand firmly on the ground.

This is a model of a blackboard, and it can't be called a blackboard, because it's still a few wooden boards, pure wooden boards, it's a whiteboard, it's not black, and there is no way to write on the board, and there is no way to wipe it after writing it, so it must be made into a blackboard.

It's such a simple thing, but its production process is very complicated, mainly because the black paint of the blackboard is not easy to do.

We searched for several days, and finally found a few lacquer trees in the deep mountains, at this time the lacquer trees are growing luxuriantly, the strong smell spreads, some people touch the lacquer tree or even close to the lacquer tree will grow packs and itch, and finally the whole body is a large piece of red envelopes, itching people can't stand it.

Two children couldn't stand the poison of the lacquer tree, and they had paint sores all over their bodies, and before they returned home, they picked out the itchy places on their bodies with their fingernails along the way, which made their father feel sad for several days.

When the children arrived at home, the mother quickly scooped out a pile of cold ashes from the fire, mixed them with water, and smeared them on them.

This method works very slowly, at the beginning, the children itched all over the body, everyone just used their hands to help them keep pressing on their bodies, they didn't dare to scratch at all, and a grasp was a bloody road.

It wasn't until the next morning that the itching slowly subsided.

Speaking of these children with lacquer sores, let's talk about their lacquer cutting.

The several lacquer trees found are thousands of years old, high into the sky, luxuriant branches, with a killing knife and an ax on the body of the tree to cut, it slowly flowed out of the white slurry, this is the raw lacquer, everyone quickly took the bamboo tube to pick up, enough to catch five or six cylinders. After the harvest was full, my father put the crab shells he had picked up by the river into the bamboo tubes, which would prevent the lacquer from hardening too quickly.

When it comes to the home, these lacquers have changed from white at first, through red, and finally to black-brown, a bit like the color of black sheep dung.

Another wave of people went to the mountains to find the fruit of the tung tree, that is, the tung oil seed, and could not find the new fruit of the tung tree, but must find the old fruit that fell on the ground in the first year, and there were also individual fruits in the first year that were still hanging on the tree and did not fall.

After finding the tung oil, they peeled off the skin, cleaned the black stuff on the outside of the fruit with water, and then dried it in the sun, and then put it under two relatively smooth stones to crush the tung oil.

When the lacquer and tung oil are ready, the lacquer is exposed to the sun and slowly stirred with a wooden stick while drying. After two days, tung oil is slowly mixed into the lacquer, and the lacquer is cooked.

Once the lacquer is done, you can paint the board into a chalkboard.

However, it seems that something is missing, yes, putty. It's even easier to make putty, pig blood, limestone, tung oil, stone powder, and crushed twine are all ready-made, and they are made in two days.

Layer by layer of putty, then layer by layer of cooked paint, after natural and slow drying, a smooth blackboard is made.

This thing made everyone happy for a while, and they had seen it in the school for many years. Now looking at it in this deep mountain valley, it is like a world away, and everyone is not very emotional.

It is relatively simple to make chalk, there is raw gypsum nearby, which is directly put into the iron-making furnace to be cooked, and then crushed into powder with a stone slab, and finally the cooked gypsum powder is stirred into a paste with water, and it is poured directly into a bamboo tube with the thickness of the thumb, and when it dries naturally, you get chalk.

It's just that the wiping board is not very good-looking, and it is a wild loofah pulp that has been picked up and dried, but it is okay to use it, and the effect is not bad. In order to prevent the wiping board from being useless after it is scratched, the children collect the seeds on the wild loofah and plant them nearby, hoping to grow new wild loofahs.

On this day after everything was ready, everyone finished work early, had dinner, some took a bench and sat on the platform, some stood giggling and watched how the eldest son taught everyone to read, and the babies were all hugging and babbling in their mother's arms, and some squatted on the ground, not at all like a class.

The eldest son was more uncomfortable in the first class, after all, he didn't know a few words, but with everyone's encouragement, even if he wrote it wrong, it was just used by his family to report the news, and he thought about it, and he couldn't create a new text if he wrote it wrong.

The people who teach are very serious, the people who learn are also very serious, it is not easy for a family to have today's situation, and it is not easy to maintain it, we must study the text carefully, otherwise what to do in case of emergencies in the future.

Since then, everyone has been busy, while every day in the afternoon early after dinner, before standing guard, spend half an hour to learn words in class, regardless of whether the eldest son taught right or not, anyway, everyone learns like this, men, women and children know this meaning, some words the eldest son really can't write, just make up a random one, everyone according to this way to express.

After recognizing the words, it was dark, and everyone coaxed the children to sleep, stood guard, and made supper, and continued to be busy.

Time flies, and in a blink of an eye it is the hottest time of summer, and the autumn harvest is approaching, and the potatoes, buds, rice, and rape are all harvested.

The potatoes and buds were still enough to eat from last year, and there were three whole houses.

The rice grew well, and 2,523 seeds were harvested, and after being dried in the sun, my father made several wooden boxes, which were covered layer by layer, and then packed in a specially made stone box on the outside, and the gaps in the boxes were pasted with lard to prevent moisture or insects from getting in.

There are rape seeds in the other box, this one is more, the particles are too small, and there is no way to count them one by one, anyway, there are two large bowls, and it will be enough to sow seeds next year.

This year's hemp and wild cotton are growing well, the mother, the mother, the second mother, they made a new dress for the family, and used the old clothes to make a pair of small shoes for the babies, which looks very fun.

My father also restarted the iron-making furnace and made two pairs of scissors for my mother, which was a delicate job that took seven or eight days to be busy.

Looking at the rice and rape seeds that were recovered, my father recalled the hard work along the way over and over again, treating the seeds as if they were treasures, sometimes touching the stone box every day, and then simply dividing the seeds in the stone box into two and storing them in two places, so that even if the seeds in one place went wrong, there were seeds in another place that could be used.

Everyone understands this emotion of the father, in fact, everyone is also the same mind as the father, all this today is not easy, every small change and new things to come, will bring a great difference to the life of this family.
