'You have to come, it's not an ordinary bathhouse. It's a new experience, a new way to take a bath, and you'll love it once you come to it. ’

'You have to come, it's not an ordinary bathhouse. It's a new experience, a new way to take a bath, and you'll love it once you come to it. ’

If you copy and paste it again, will you be scolded for cheating the number of words? It should be, but it's really not that the author wants to cheat the number of words, nor because important things have to be said three times, but Li Chen said the same sentence in three different places.

Now that the Chinese New Year is approaching, Li Chen's Vashe is about to be completed, and some of them are about to be completed. Because it is a sectional construction at the same time, there is no need to wait for the other parts to be completed, a part can be completed, and a part of it can be opened first, which is conducive to the return of Li Chen's funds.

It was completed so quickly, thanks to Li Chen, who let the students go to the construction site for a while to intern, originally just to let them see, but I didn't expect the students to play a lot of places, it can be said that without the help of his group of children, this base would not be fast at all.

First of all, they helped to complete the gantry crane, which can easily lift heavy objects and then move to a certain range, saving a lot of manpower. In addition to this, in construction, they help even more.

Because in order to complete the project as soon as possible, Li Chen increased investment and hired more workers after he had money. But many of them have no experience in this at all, and they do things based on their previous experience.

How many people are used for each job is experience for them, they used to teach by word and deed, learn from their father, and after they become teachers, they will follow their previous experience and their own observations. How much work it takes, how long it takes to complete it, and so on.

It's just that, as we all know, quantitative change will produce qualitative change. It's not that a house needs to be built for 10 days for 10 people, and 5 days for 20 people. Sometimes there are too many descendants to mess up, not only does not produce the effect of acceleration, but drags down the progress.

As a result, as soon as this group of children went, they helped sort out the moving line, so that the construction speed increased, and the whole site was orderly, which made many craftsmen's eyes widen, this group of children has such a big ability.

Next, there's that. Since it is to be managed, there must be numbers involved. Arithmetic is their specialty, and they let a master craftsman kneel on the spot, this master craftsman is very talented in arithmetic, and he has also learned arithmetic. As a result, when a child holds an artifact in his hand, he kneels in a flash.

If you want to do a good job, you must first sharpen your tools, and since you want arithmetic, of course, you need tools. At first, Li Chen didn't expect that when he was in Changshou Temple, he didn't think of using tools to assist, and he completely relied on mental arithmetic, which was great to cooperate with the sand table. Later, when he came to Xu's Mansion and opened Elysium, he had a special account room, so he didn't have to calculate it himself.

Later, he taught the child arithmetic, and he didn't think of what tools to use. Because from elementary school to middle school, there are few tools used in mathematics classes, and they all require hand calculations. That's how he taught. It wasn't until he left Xu's Mansion that he asked the children to help clean up the account books, and some children said that every time he remembered any number, he asked for paper, which was very waste paper, and if there was any other way, he thought that he could use an abacus.

Li Chen was negligent, he only asked the children to be able to calculate and do math problems, but he didn't expect that in practical application, tools are needed to calculate quickly and well. There are computers in modern society, what were they used in ancient times? Li Chen first thought of the abacus.

Thinking of it, he started to make it, this thing is not complicated, Li Chen found a craftsman to make a few calculations. Then they began to teach them how to use the abacus. It's amazing that when he invented the abacus, some mantras came to mind.

The abacus master can dial the abacus faster than you press the computer, not simply using addition, subtraction, multiplication and division directly, relying on the formula. What one five to four, two five to three, and so on. Regardless of addition, subtraction, multiplication and division, there is a formula, when the calculation is done, rely on the formula to pluck the beads, and after dialing, the final result is the answer. It's all a matter of proficiency.

When a child took out an abacus, he let the craftsman who had learned to do the arithmetic kneel on the spot. The origin of the abacus is no longer known, but it seems that it did not appear until the Song Dynasty in China. So what calculation was used in the Tang Dynasty?

Strictly speaking, the Tang Dynasty did not have an abacus, otherwise the ancients relied on what to calculate, it was impossible to take out a calculation paper every time, and the Tang Dynasty used a thing called calculation.

In fact, this can be said to be an abacus, which was originally only used for counting, and later with some tricks, it became calculating. This is expected to be used as a calculation. As a result, he took out the calculation chips, wanting to give these children who looked very powerful a little color, so that they would know that ginger was old and spicy, and the back waves of the Yangtze River could not push the front waves.

As a result, when the child took out the abacus, he quickly calculated a lot of complicated accounts, and he wanted to apprentice on the spot. What kind of artifact is this, why is it so powerful, it's just a small frame.

It's a lot of money. How many are there? This kind of thing was used from the Zhou Dynasty to the Tang Dynasty, and the improvement was to make it as small as possible. According to the Sui Shulu Chronicles, "its algorithm is bamboo, two minutes wide and three inches long, and the three incorruptible policies are two hundred and sixteen pieces into six pieces." Negative strategy four incorruptible, 144 pieces of square. ”

That is to say, no matter how much this kind of thing is improved, there is no convenience, the number is still very large, and the great thing is to reduce it as much as possible, and by the Sui Dynasty, three hundred and sixty more are needed. It's probably a year. The ancients had a superstitious color in many aspects, but no matter how you look at it, it is not as convenient as the abacus, no wonder as soon as the abacus comes out, people kneel.

The children worked hard to make the construction very smooth. Li Chen was very glad that he brought that group of his students to help, originally just to give them more experience. He didn't want to limit their future development, he wanted them to have more experiences, maybe he would find out what he was interested in, so he would take them to the construction site for internships, but he didn't expect it to really help.

Don't look at the perfume coming out, his financial pressure is temporarily relieved, don't forget, he still has enemies, and it will be a day before he can cover it one day earlier.

The first thing that is about to be built is the bathhouse. Yes, Li Chen built a new bathhouse, which was his dream in Xu Mansion for a long time, to let the Tang people experience a new way of bathing. Now that it was almost finished, Li Chen ran to several places and went to find Zhao Liu first.

'What is this?' Zhao Liu took the small note handed over by Li Chen and read it according to it, "Sauna reception coupon, but the two of them can go together." Zhao Liu was so fresh that he flipped the note from side to side, looking very curious.

'It's an advertisement. After Li Chen finished saying the above advertising words, he gave Zhao Liu an advertising flyer and an invitation coupon. In later generations, this was a very common practice, but in the Tang Dynasty, when engraving printing was not yet widespread and paper was still very precious, this method was very new.
