Accompanied by Chen Wannian and Sang Jun, Zhang Yue came to the official residence of the Industrial and Commercial Bureau in the center of the Workshop Park.

Zhang Yue raised his eyes and looked at the building in front of him, no matter how he looked at it, he felt that it seemed to be a miniature replica of the official residence of Chang'an Dasi Nong.

Even at the door, like the official residence of Chang'an Dasi Nong, five pines and cypresses are planted.

It's just that the pines and cypresses of the Xinfeng Industrial and Commercial Department are just seedlings......

"Waiting...... Please ......" Sang Jun personally stepped forward and pushed open the door of the official residence for Zhang Yue.

The officials of the entire industrial and commercial office have already lined up on both sides of the door.

When everyone saw Zhang Yue, they hurriedly saluted: "The lower officials and others respectfully ask the public security in the service!" ”

Zhang Yue looked at them, his eyes sweeping over them.

Most of the officials of the Industrial and Commercial Bureau were personally selected by him during the public examination.

Therefore, he can even call everyone by name, and even memorize their origins and family backgrounds.

"Everything is safe in this official...... Zhang Yue smiled and bowed his hand in return: "I also wish you peace!" ”

So, surrounded by everyone, I came to the main hall of the Industrial and Commercial Bureau.

"Please ......" Sang Jun lowered his head, led Zhang Yue to the top position, and bowed: "Please take a seat in the waiter......"

Zhang Yue didn't shirk and sat down directly.

Only then did Sang Jun arrange Chen Wannian to sit down under Zhang Yue, and he sat opposite Chen Wannian, waving his hand slightly, and the officials of the entire official hall immediately sat down in an orderly manner.

Zhang Yue took his eyes and looked at the main hall of the Industrial and Commercial Bureau.

The surrounding walls are covered with abacus.

A rough count, at least fifteen or more!

It seems that Sang Hongyang has supported many of Sang Jun's abacus experts!

As a result, the Xinfeng Industrial and Commercial Office has become the first official office in the world to fully use abacus for office.

It is said that the officials of the Industrial and Commercial Bureau, as long as they have an establishment, have now used abacus to work.

This new calculation tool and calculation method also makes Xinfeng Industry and Commerce an extremely efficient organization.

Many things that used to take three or five days to get results can now be seen in just half a day!

This enables the Commerce and Industry Department to fully monitor the activities of the entire workshop.

Sang Jun said triumphantly in the quality day: Since then, the Jia people's orders are all in my eyes!

This is indeed a terrible thing, especially for merchants.

Once the government has figured out their production and business activities and capital flows, it may not be so simple to evade taxes and evade taxes.

Why is Sang Hongyang so hated?

He was very good at collecting taxes, which accounted for a large part of the reason.

However, for the time being, Xinfeng Workshop Park is still a paradise for businessmen.

They don't need to worry for the time being, they have just made money, and before they have time to heat up, they are visited by officials from the Department of Industry and Commerce and want to take away some of them.

"Before this official went to Chang'an, he had sent an official letter to the princes of the Industrial and Commercial Bureau......" Zhang Yue looked at everyone and asked slowly: "I ask the Industrial and Commercial Bureau to make a complete set of standard weights and measures as soon as possible, so as to facilitate the people...... I wonder how this work is doing now? ”

The book is the same text, the car is on the same track, and there is a degree of quantity, which is the sign of Qin and the world.

It's just that when it came to Hanji, the once uniform standard of weights and measures became chaotic again.

This may mainly have to be carried by the Huang Lao School.

Because, the politicians of the Huang Lao School, who were in power back then, adhered to the attitude of 'as long as the people do not break the law, even if he wants to blow up the earth, let him go'.

This caused the extreme prosperity and prosperity of industry and commerce in the world between the Han family and the cultural scene.

At the same time, it also caused the whole standard of weights and measures to be disordered.

You know, back then, in order to make money, those profiteers did everything!

When private money was overflowing, it was a conscientious merchant who mixed lead and iron into the coins.

Guys with no conscience are mixing lead and iron with copper!

What's even more terrifying is that these guys are extremely careless about making money.

The weight of various coins varies, and many coins carry the banner of eight baht coins, but the actual weight is only five or six baht.

But the politicians of the Huang Lao school turned a blind eye to this.

In their opinion, the people did not break the law!

Because there is no state regulation that says that private minting is prohibited!

So, they decided to leave this matter to the 'market' to solve.

The result is the market, and it really solves this problem for them - you say my eight baht is six baht, right? Mud legs! Open your eyes and take a closer look, how many baht am I tired of?

Yes, these smart guys, they themselves did a copper tired of weighing money, and then they set their own standards that are in their own interests!

Anyway, the peasants don't even know the words, so they can easily get rid of it.

But this is only one of the cases of the disorder of the standard of weights and measures in the early Han period.

In almost every other standard, everything is already out of order.

For example, in the Guanzhong area, land is subject to the Qin Dynasty's large mu system, and one mu of land is 240 steps wide and one step wide, while in most areas of the Kanto region, one mu of land is 120 steps wide and one step wide, and the standard of land tax to be paid is the same......

For example, in Chang'an, a stone of grain weighs four pounds and one hundred and twenty catties.

However, there are smart people in the people who invented small buckets, and some small buckets are only one-third of the official fighting weapons.

When they lend grain to the peasants, they use small buckets to borrow it, and when they collect debts, they exchange it for large buckets......

As a result, the whole world is almost in chaos.

Many farmers in remote areas, in order to avoid being trapped, do not even accept coin trading.

They are only willing to barter or trade cloth.

The disordered standards of weights and measures have also adversely affected the development of the handicraft industry.

Fortunately, before Zhang Yue, the famous minister Erkuan had already sorted out the chaos of weights and measures in the world, stipulated the system of corresponding specifications, and explained in detail the division of their respective standards.

It's just that......

Although the state has made regulations, few people below are willing to do it.

Because, the matter of weights and measures, thankless.

Painstakingly doing it may not be effective.

It will only attract the disgust of the powerful landlords and wealthy businessmen under their rule!

Moreover...... To be honest, there are very few people in the whole world who have this level of technology and can cast such a measure accurate to the cents and baht.

After all, this is not the afterlife, the era of great industry.

Humans can even measure nanometers and quarks and accurately calculate their size.

And now...... Not to mention, there are probably not many technicians in the world who can process a copper tired with a weight of one standard 'baht'!

And those who can accurately mark 'inch, minute, cent, millimeter' on a one-foot-long copper ruler are probably less than ten fingers.

Even if the conditions are relaxed from one baht to five baht, and the smallest unit is changed from milli to cent.

There are probably not many skilled craftsmen in the world who can do such a thing.

Therefore, officials from all over the country simply let the sheep go.

But Zhang Yue knows how much of a role a set of accurate weights and measures can play?

There are no rules.

Without accurate weights and measures, it is impossible to further improve the technical level and manufacturing level of the Han family.

Therefore, after the listing of the Industrial and Commercial Bureau, the first important task that Zhang Yue handed over to this organization was to manufacture a set of weights and measures that meet national standards.

Sang Jun listened to Zhang Yue's question, hurriedly got up, and bowed: "Back to the service, the lower officials and colleagues, day and night, full cooperation, and rely on the service to give documents and drawings, now, fortunately, has produced a set of weights and measures, I would like to ask the service to take a look!" ”

As he spoke, he clapped his hands, and then a dozen officials walked in carrying a complete set of measuring instruments made of copper, iron, and other metals.

Zhang Yue got up and looked at these vessels of different sizes.

Go up to them and look at them carefully.

Different from the general impression of later generations, the Qin and Han dynasties can be called the pinnacle of the subdivision of weights and measures, and have almost reached the upper limit of what can be achieved in this era.

Just like now, these four sets of different styles of metrics appear in Zhang Yue's sight.

In the Han Dynasty, weights and measures were divided into four parts, which were called 'law, degree, measure, and weight', corresponding to the law, the vessel, the measuring instrument, and the weighing instrument.

But in fact, these four kinds of metrics are from the same source.

They are all evolved from the ancestor of the Zhuxia nation, a musical instrument made by the legendary Yellow Emperor - Gong!

As a result, the gong became the smallest unit of container in China since ancient times.

According to the understanding of the Han people, Yigong is the smallest timpani among the Yellow Bell instruments.

According to the standard stipulated by Zhang Cang, the Marquis of Beiping in that year, a dragon is nine inches long and nine square in diameter, which is 20.79 centimeters long and 0.72 centimeters in diameter.

Such a small tube, when it can hold 1,200 grains of millet, should weigh 12 baht.

So the weights and measures are perfectly unified on a single utensil.

It's just a pity that the ideal is plump, and the reality is the backbone.

First of all, millet is a crop with different fruit grains of different sizes and weights.

Although each grain looks similar to the naked eye, when 1,200 grains of millet are piled together, the quantitative change produces a qualitative change.

And this kind of discord is too big, and when people try to use it as a standard to calculate other data, as the units increase, deviations appear.

But any attempt to abandon the unit of the Gang is unforgivable.

It is a great rebellion that completely violates the teachings of the previous kings and the teachings of poetry and books!

The book says: Weights and measures with the same law, and also says: First set up fortune telling, Confucius said: Be cautious in the measure of power, judge the law, abolish the officials, lift the people, and the government of the Quartet!

From the perspective of the ancient Zhuxia philosophy, music is the origin of all things and the foundation of all civilization and education.

It is the forerunner of mathematics and contains the infinite wisdom of its predecessors!

It is the torch of civilization, the light that illuminates all things!

It can lead people to goodness, and it can guide those who have lost their way back to the right path.

It is faith!

It is Zhuxia!

Anyone who tries to deny this theory is tantamount to self-isolation from the world in this era!

And, the other key measure of millet cannot be denied either!

Because this is the first crop that the ancestors came into contact with, it is the first plant domesticated by the ancestors.

In the hearts of the people, millet represents the wisdom and spirit of the ancestors.

Giving up millet means giving up the ancestors, which is tantamount to betraying the ancestors and betraying the ancestors, and will be sent into the mountains to be a savage!

Therefore, Zhang Yue can only find another way.

Fortunately, later documents and archaeological discoveries have provided him with countless inspirations and help.

In the new Mang period, Wang Mang, a guy with thick eyebrows and big eyes, made important changes within the rules!

The first is that he mass-produced a variety of accurate metrics.

Secondly, he subdivided two smaller unit standards - the sum and the divide.

A pinch is about 2.07 ml, and one is about 1.2 ml.

Then he prescribed a point of 64 grains, which perfectly solved the problems caused by the standard of millet and millet particles in the context of the technical limitations of the times.

Zhang Yue touched Wang Mang to cross the river, and naturally had an idea.

Before leaving Xinfeng, Zhang Yue asked Ding to make an ingenious trade-off—similar to the weighing of the equiarm balance in Western Rome.

Then, let Ding slowly refine this trade-off so that he could accurately measure sixty-four grains of millet and place fine sand on the other end of the scale.

Thus, the problem of the standard unit of weight was solved.

On this basis, Zhang Yue ordered the Industry and Commerce Department to manufacture a new weighing and measuring instrument based on this value.

At this moment, look at the four sets of measuring instruments in front of you.

Zhang Yue stretched out his hand and gently flicked the 'rhythm device' at the front, which was composed of tubes of different sizes.

The crisp voice echoed in the official office.

"Participate in three changes, intricately few, the way of the first king is beautiful!" Zhang Yue said softly: "Therefore, since ancient times, kings have ruled the industry, and first established arithmetic to live a hundred things!" ”

He looked back at the officials and said earnestly: "All kings should remember the precepts of the previous kings, number is the mother of all things, the foundation of all things, it can be abolished, and the only number cannot be abolished!" ”

"No!" Everyone replied respectfully, and they all had their own ideas in their hearts.

But Zhang Yue's instructions were all kept in mind.

Zhang Yue stepped forward and looked at the power instrument (weighing instrument) behind the law.

The power of Han Ji is ring-shaped.

Layer after layer, there is only a thin layer of copper at the bottom, which weighs only a baht.

Zhang Yue gently lifted them and let them run across his hands, feeling their rhythm.

The power is the most important and crucial creation for the people!

Because it is directly related to the production, life and transactions of the people.

After all, the majority of the population is illiterate and illiterate.

The only counterpoints they can refer to are these instruments.

With this set of standard power weapons, profiteers and powerful people will have to change their ways if they want to play tricks in the future.

"Baht two catties of Jun Shi ......" Zhang Yue nodded with satisfaction, then turned around and looked at the ruler that was placed on a desk.

This ruler is different from all measuring tapes today.

It's not just its accuracy – it's measurable down to the millimeter.

This unit is almost unrecognizable to the naked eye.

What's more, there is a small thing on this ruler.

A small caliper that can move freely and snap onto any surface on the ruler.

Zhang Yue picked it up, his heart full of pride.

Because this ruler is more advanced than the original calipers unearthed in the Xinmang period in later generations!

Wang Mang's calipers can't move, and it can!

With this ruler, the craftsmen of the Han family will be able to do more!
