suspected wife

Qiao Mingjin was very satisfied with what He Xiaochun had made.

The family has never bought anything like pens or inks, and she and He Xiaochun just talked about it, pointing here and there. Completely made without any difference, good-looking novel:.

It completely matched what Qiao Mingjin remembered.

Originally, I used He Xiaochun's craftsmanship to make an abacus. After selecting the materials, no matter how finely polished, one can be finished in two or three days.

But it took a month to make it.

Of course, He Xiaochun did more than just a calculation.But many, many.

There are no patent rights in this era. If this thing is made, others will definitely imitate it if they see it is easy to use.

Not to mention that there are many carpenters these days, even ordinary households have one or two who can do some carpentry.And it's not that hard to do.

If you can't prevent others from imitating, you can only seize the opportunity.

Qiao Mingjin's idea is to grab a large number of them first, and then find a good way to sell them.By the time others realized that it was a good thing and imitated it, she had already sold a lot and made her first pot of gold.

Qiao Mingjin asked He Xiaochun to make a hundred of them in one go. Except for a few of them, no one knew what he was making, and he did a great job of keeping it secret.

Now these one hundred abacus are piled up in the servant's room, making a huge pile.

Qiao Mingjin took an abacus that was still smelling of the original wood and looked at it carefully in his hand. He rubbed the wood grain and corners on it carefully. Very comfortable.

This abacus has been improved by Qiao Mingjin who came from later generations, although it looks not much different from the current abacus.Rectangular, divided into upper and lower beams, there are more than a dozen or twenty stalls, but when you look closely, it is still very different from the abacus used by people at the time.

First of all, it is no longer the swarthy color that people used at that time.

Qiao Mingjin didn't ask He Xiaochun to paint, but just applied a layer of varnish to brighten it a little, so as to maintain the original quality of the wood.

You can also see the nice wood texture on it.It is very easy to look at, and the eyes will not feel tired after using it for a long time, and it will not make people feel dizzy and depressed after staring at the black abacus for a long time.

This is an important change in overall color.

The other change is from bead to bead.It doesn't all fit together anymore either.

In order to facilitate the liquidation of abacus nowadays, the round space in the middle of the beads is made quite wide.It is often seen that the accountant holds the abacus and shakes it for a while before using it, and the beads are shaken.Then there was a loud sound of winding up beads by hand.

Such beads are easy to make mistakes when winding up, and it is easy to float or carry beads when dialing.

Floating beads means that when dialing, the force is too light and do not rely on the gear or the beam. With beads, when dialing is fast, because the distance between the two beads is close, it is easy to bring the beads that are not on the standard position.

sometimes.A small difference is a thousand miles away.

Qiao Mingjin's calculations are all based on the modern improved version.

Make the round beads into a rhombus shape, so that only the cut face beads around the beam are connected together.The whole bead is made into a diamond shape, so that there is a lot of space between the beads and they are not close together.It avoids mistakes when dialing the beads, and the beads below will also be dialed together.Error rate is avoided.

This is how it looks.These are the two most important changes.In addition, there are two major changes.

One is that only one of the two beads in the upper gear is made, and only four of the five beads in the lower gear are made.

Because in the process of abacus calculation, the top and bottom are hardly used.

Because "if you go to five, you will go to four, and once you go to nine, you will enter one", good-looking novels:.

The top and bottom beads are used very infrequently.Almost useless.

The other one is a piston that has been liquidated in the upper left corner.Made a frame.

This way you don't have to work hard and waste time to liquidate.

When the current abacus is about to be liquidated.After calculating this account and going to the next one, I still use one or two hands to dial the beads on the upper and lower gears, and I have to grab them and shake them. If this is the case, not to mention wasting time, it is easy to clear them incorrectly.

With this piston winding mechanism, you can simultaneously press the liquid piston with your left hand while finishing calculations with your right hand.

In this way, the beads on the upper and lower beams are automatically dialed back to the upper and lower gears by the mechanism, and they are neat and uniform, and there will be no non-filing situation.

For example, there is an automatic mahjong machine for playing mahjong, which does not require you to code the cards, and there is also a semi-automatic card code made of bamboo chips.

These are the most important changes of the modern abacus.Qiao Mingjin believes that if these abacus are sold, people who know the goods will definitely buy them.

It's not a butterfly's wing, is it?

This is just a very small change.After Qiao Mingjin came here, she found that people nowadays are extremely intelligent, and she discovered many things that surprised her.

Maybe there are many handicrafts in the long river of history, because of the secrecy of the family, or the inheritance of generations, many things have not been seen by later generations.

Maybe this calculation is the same, maybe someone else has already figured this out.It's just that there is no sale in the world.Qiao Mingjin never doubted the wisdom of the people nowadays.

Just like He Xiaochun, after she just told him once, He Xiaochun knew what to do.

After listening to Qiao Mingjin's explanation, the whole family took a handful in their hands, regardless of whether they would or not, pressed the liquidator and made the abacus crack.

Several children couldn't put it down, and everyone insisted on a handful.

Qiao Mingjin said to sell it first, and then make one for each of them after a while.At that time, I will make a small one for Xiao Wan'er, and the little thing will immediately smile.

In addition to one hundred large abacuses, Qiao Mingjin also asked He Xiaochun to make twenty extremely exquisite and delicate abacuses that were only the size of a palm.

She was planning to sell these twenty for a high price.

Nowadays, if people go out, or want to collect rent wherever they go, they will bring their own abacus.

There are big ones and small ones, some of which are extremely exquisite, and the materials are different, and some exquisite ones are all made of black jade.Carry an abacus with you when you go out.

When it's time to use it, just take it out and shake it, then liquidate it, and then calculate it.Because for the convenience of liquidation, the round hole in the middle of the beam is very large, so some people's abacus hanging on their waist will crackle as they walk.

Some people even deliberately made some noises. Nowadays, if you are engaged in account work, it is a very enviable job.The wind can't blow the rain, and the wages are high.

Those who can understand addition, subtraction, multiplication, and division these days must have worked hard to learn, and they are all literate. These tents walk on the road with their waists straighter than others.

These people have money in their pockets, and Qiao Mingjin intends to sell these twenty abacus to these people.

After dinner that day, Qiao Mingjin discussed with his family how to sell.

Ps:

This chapter is a bit short.I have to go to the company in the afternoon.There will be another chapter tonight.It might be a bit late.Thank you guys.What a.
