    "Father, please take two steps forward!" Li Min held a ruler without scale in his hand and said to Li Shimin with a smile on his face.  This is a small school ground in the palace. In addition to the father and son, they are also accompanied by Duan Lun, who is the minister of the Ministry of Industry. However, looking at the reluctant look on his face, one can guess that he was forced to do so by Li Min.  Come.

    "Liu Lang, is it necessary for you to do this?" Li Shimin walked a few steps forward with a smile, and asked Li Min as he walked.  Just after the court today, his son entered the palace and insisted on dragging him to do some measurements. Although he could not figure out Li Min's intention of doing such a thing, it was still a move to leave a name for himself, so he also behaved  Show some interest.

    "What your Majesty said is true. I also think that His Highness King Qi is unnecessary!" Duan Lun is not an outsider and has a very good relationship with Li Min, so he doesn't care what he says. Besides, he still has a lot of things waiting for him to deal with in the Ministry of Works.  , I really don¡¯t want to mess around with Li Min here.

    "My father and uncle don't know something. This is not a joke on my part, but it is related to the future development of industry and commerce, so don't underestimate this matter!" Li Min still explained with a smile.

    A few days ago, he and Changsun Wuji reached an agreement on the throne and waited for the opportunity to push Li Zhi to the throne. He also warned the other party to assist Li Zhi honestly and not to have any other ideas.  Although Changsun Wuji felt very angry, he was finally overcome by Li Min's momentum and strength.

    However, after settling the matter of Changsun Wuji, Li Min was troubled by another matter, and this matter he discovered by accident.  Although nothing is visible now, it may cause great inconvenience in the future.  That's why Li Min made up his mind to solve this hidden danger this year.

    When Li Shimin walked a few steps on the school field, a series of footprints immediately appeared behind him. Li Min stepped forward with a blank ruler, measured the distance between each footprint one by one, and then handed it to the person next to him.  Let it take an average, and then multiply this average by two, and you get the distance of one step.  Let me explain it here.  In ancient times, a step refers to the distance after two feet step out alternately. A person who only lifts one foot is called a step, and two steps are a step.

    The person next to you calculates the distance of one step.  Then he made a mark on the blank ruler, and then cut off the excess part of the ruler. Then he handed the ruler to Li Min. He was holding the unmarked ruler in his hand, with excitement on his face, and bowed.  He said to Li Shimin: "Father, this is the new unit of length in the Tang Dynasty. In order to distinguish it from the current unit of length, I decided to call it the imperial step, which can also be called the public step!"

    Li Min wanted Li Shimin to agree to his next move.  The words were meant to flatter the other party. Anyway, it is just a unit of length. It is also called a meter, and it is also called a step. There is not much difference at all.

    At the previous Winter Games.  Especially during bicycle competitions, Li Min accidentally discovered a problem, that is, bicycles damaged during the competition can rarely replace parts at will like later generations. Expert craftsmen must specially customize parts for the lost bicycles before they can be used again.  .

    This discovery made Li Min very strange.  After he took a closer look, he realized that there are different bicycle manufacturers now, and each factory has its own specifications. Even bicycles produced by the same manufacturer have different specifications.  This is mainly because the production process of bicycles is extremely irregular. An experienced master and a group of apprentices are responsible for everything from the selection of bicycle materials to the final installation and debugging. This results in every  The bicycles produced by the old masters all have slight differences, and it is difficult to use common parts between them.

    Regarding this discovery, Li Min originally wanted to introduce the assembly line work of later generations, but later found that it was not feasible at all, because there was another most basic problem, that is, the non-standard weights and measures.  Originally, Li Min thought that since Qin Shihuang unified weights and measures, ancient China should have been unified in this regard, but after learning about it, he discovered that this was not the case at all.

    Speaking of which, our ancestors don¡¯t know what to think. Things as basic as weights and measures have been constantly changed. Although the name may not have changed, the meaning has undergone tremendous changes. Even each dynasty has its own  of weights and measures.  For example, take the length unit chi as an example. This unit existed as early as the Shang Dynasty. When converted, it is approximately equivalent to twenty centimeters in later generations. However, perhaps the ancient kings did not associate this unit with imperial power. Each dynasty  The new one must be a little longer than the original one foot to show that it was different from the previous dynasty. By the Tang Dynasty, one foot had reached 30 centimeters.  Moreover, the country was only founded a few decades ago during the Zhenguan period, and many places still used the dimensions of the former Sui Dynasty. Therefore, the length represented by one foot may have different lengths across the country.

      This is true for the simplest units of length, not to mention units of area, volume and weight.  There are no unified weights and measures, let alone unified industrial standards, so Li Min's assembly line is impossible to talk about.

    Regarding this situation, Li Min had to start from the most basic aspects and prepare to formulate a set of industrial-specific weights and measures, but this matter required the participation of the Ministry of Industry. Although Li Min had a good relationship with Duan Lun, in this kind of situation  In fact, he was not sure of convincing the other party, so he turned to Li Shimin and set the length unit as the other party's step, which is why today's scene happened.

    "Your Highness, our Tang Dynasty already has weights and measures, and the people have already adapted to it. There is no need to use a new set of weights and measures!" Duan Lun still objected. He mainly considered that the current weights and measures have been accepted by most people.  , if another set is launched rashly, it may cause confusion in the market and cause unnecessary trouble to their Ministry of Industry.

    "Uncle, you misunderstood. My set of weights and measures is not for private use, but for industrial production. It does not conflict with the original weights and measures." Li Xin explained with a smile.  The situation he mentioned is very common. For example, when buying things in later generations, although the standard unit of weight is kilograms, Chinese people still generally use the unit of market jin, which does not have much impact.

    "Then I don't understand. Why not just use the original weights and measures in industry?" Duan Lun asked.

    "Uncle, haven't you found that the original weights and measures were too complicated? Taking the unit of weight as an example, there are units such as baht, liang, catty, jun, stone, etc., and the carrying between them is very complicated. Among them, twenty-four baht is  One tael, sixteen taels is one catty, thirty catties is one jun, and four jun is one stone. The rounding between these units is different, making calculations very complicated. In addition, the units of degree and quantity also have this problem.  , Industrial production requires a lot of calculations, and the old weights and measures simply cannot meet this requirement, so I had to come up with a new set of weights and measures"

    When Li Min said this, he briefly introduced the weights and measures that he thought of. It is actually very simple to say. Most of them refer to the units of later generations. For example, the units of length include steps, cent-steps, centisteps, millisteps, etc.  , and they are all based on the decimal system. In fact, the meters of later generations were replaced by steps, and the distance of one step was set as the length of Li Shimin's step.  With the unit of length, volume becomes easier. Just introduce the concept of cube. As for weight, Li Min multiplied one pound in the Tang Dynasty by two and named it kilogram. The reason for this is mainly that the pound in the Tang Dynasty was too large.  Small, it is very inconvenient to calculate some industrial products. One thousand kilograms is one ton, one kilogram is equal to ten liters, etc.

    The units of these weights and measures use the decimal system uniformly, discarding all the original quaternary, octal, hexadecimal, and even 24-decimal systems, making calculations much simpler, and in order to facilitate industrial production.  Calculate and improve accuracy, especially adding some large and small units, such as tons, millisteps and the like.

    After listening to the new weights and measures introduced by Li Min, Li Shimin and Duan Lun also fell into deep thought. Although they were already accustomed to the old weights and measures, they had to say that the set of weights and measures proposed by Li Min was indeed easier to understand. After all,  They are all unified decimal systems. Once you understand one, you will naturally understand the others.

    "Duan Qing, what do you think?" Li Shimin thought for a while, but he did not take the lead in expressing his opinion. Instead, he asked Duan Lun for his opinion first.

    "This" Duan Lun also hesitated for a while. He knew clearly that the new weights and measures were indeed much more convenient than the old ones, but when he thought about promotion, he had a headache. Datang was so big, even if it was only promoted in industry,  That's enough to keep him busy.

    "Uncle, it is actually not difficult to promote new weights and measures, especially in industry. As long as the Ministry of Industry issues a formal provision to publish the new weights and measures, and forces all industries under the Ministry of Industry to use them, I will then convince everyone.  Industry associations, let them take the lead in promoting within the industry. In this way, both the government and the private sector will have an example to refer to. By then, other industries will not be able to remain unchanged!" When Li Min saw Duan Lun's appearance, he immediately understood that the other party was trying to  What was there to worry about, so he immediately spoke to persuade.

    When Duan Lun heard that Li Min took the initiative to help him share a lot of work, he had no worries at the moment and immediately said: "That's it, I don't have any objections, but weights and measures are very important, Liu Lang, when you are promoting  , be sure to be careful and never act recklessly!¡±

    Li Min naturally nodded in agreement to Duan Lun's instructions. In fact, he didn't need to be reminded at all. Li Min also knew that weights and measures were of great importance, and the promotion of weights and measures was not a matter of a day or two. He had long been prepared for a protracted war.

    After agreeing on this matter, Duan Lun made an appointment with Li Min to discuss it in detail. After all, the two of them wanted to work together, so naturally they had to go further.After communicating, Duan Lun hurried back to the work department to do his business.  Li Min stayed with Li Shimin for a while, and then prepared to leave. However, before leaving, he borrowed something from Li Shimin.
