The name vernier caliper came out of Song Shi's mouth, and everyone heard it, and the word "Yuanyang ruler" in the letter was immediately rushed to an unknown ocean.

When the people looking for documents in the library heard that there were new articles and songs, they all dropped the boring and annoying old files and gathered together to listen to the articles read.Song Shi didn't know how to climb down the ladder safely, but the "Parrot Song" he had just heard came into reality, and listening to it again still made him feel like his chest was on fire, and he wished he could plunge into the cracks in the ground.

In order to prove that this set of music is a complete description of the shape and usage of the vernier caliper in a realistic manner, and does not imply any hidden feelings, he hurried back to the value room to get a ruler for others to read.

Fortunately, when I took a craftsman to repair the book a few days ago, I also used a vernier caliper to measure the size of the paper material for the original book. I kept a ruler in the Duobao Pavilion of the value house. Is the divertimento simply describing the ruler?

He squeezed into the crowd with a ruler, moved the cursor, and explained the names and uses of each part, and took a small stone tripod from the shelf, measured it inside and out, and demonstrated its usage.

It is not easy to be misunderstood if the usage report is taken together with the product.

Everyone saw the vernier caliper with their own eyes, and then they fully understood the meaning of "like mandarin ducks and tails by the beach" and "forbearing to move a lone wing to the east and west, to distinguish the length of the material" in the set of "Parrot Song".

Those two pairs of long and short arms hug each other tightly, isn't it just like the pointed tails of mandarin ducks touching each other on the beach?When measuring things, the vernier must be moved to move left and right on the main scale. The single arm protruding out is like the wing of a lone goose, and the two wings that are suddenly separated are engraved with fine scales, which measure the length of their separation.

Sure enough, every word and sentence is written with a ruler, but the lyrics are lingering and affectionate, with a palace-style appearance and a rhyme like a flower. If you don't see this ruler, you may think it is expressing your own thoughts about Huaiyuan people.

However, it is also possible to borrow a ruler to send lovesickness. Who said that the ruler given to him by his junior brother cannot entrust his thoughts on others?

What if his lovesickness is not for others?

But Editor Song's attitude of being aboveboard and casually copied by others doesn't seem to have any personal feelings...

No one dared to say these guesses in front of Song Shi, so he changed to say that the name of the mandarin duck ruler is vivid: one long and one short, one big and one small, surrounded by two phases, even the big and small arms are like sleeping on the sand Cuddling with wings like birds, shouldn't they be called this name naturally?Otherwise, even the Bi ruler is interesting, but the vernier caliper is difficult to pronounce and boring, not worthy of such an interesting ruler.

It's just that what he brought was a black iron ruler with a bend, which looked like a pair of bent straight-handled scissors, and it didn't have the golden thread wrapped and magpies climbing plums written in Huan Ling's set...

The mandarin duck ruler written in this song is actually better than the one he uses himself?

Although it is human nature to give gifts and better things, but the ruler he usually uses to measure things is only used when inspecting ordnance at the border, and it seems that it does not have to be very delicate.Song Dynasty had been in the Imperial Academy for so long, and he never paid attention to luxury. The mimeograph machine that was sent to His Royal Highness King Zhou was also something made by the Imperial Academy. It had never been pasted with gold leaf. How could it be so elaborately decorated for the senior brother?

Everyone couldn't think of a reason why Song Shi wanted to please Huan Ling, and the Huan family didn't have a second daughter who was in her prime, so it can only be said that they have a deep friendship between teachers and brothers.

Fortunately, all the sages of the Imperial Academy have seen the world, and secondly, they are gentlemen who don't talk about others. They never came to Song Shi to find out the truth. Instead, they copied Huan Ling's letter and "Parrot Song" and slowly Copy it.

It didn't take long for Song Shi to hear that the craftsman who made the ruler for him also secretly changed the name of the vernier caliper to Yuanyang ruler, and the number of customers ordering rulers at his house increased sharply—eight out of ten were not engaged in science and engineering, but I want to buy it as a love token.

... Forget it, this is also conducive to the spread of technology.

The name Yuanyangchi is not without its advantages.With a name in line with the times, the popularity of vernier calipers has surged, and the popularity of rulers has led to an improvement in badminton: because the vernier calipers measure more finely, the heads of badminton balls are cut more rounded, and the length and width of the trimmed feathers are accurate to the centimeter. The ball is better balanced in the air and less likely to fly or spin.And because the size of the arc of the feather tip can be measured more accurately, the balls made by various craftsmen can fly higher and farther after repeated trial production.

There are also several blacksmith shops that have followed suit and learned to use vernier calipers.Those who are not skilled enough can hang a ruler on the counter, and when the guests come, they will say that their things are measured by mandarin duck rulers, and they are guaranteed to be finely crafted.There are also those who do woodwork, bamboo, bricks, glass, porcelain...they are placed in various shops, as if their skills are simply superior, and they have more confidence to brag to customers when they sell things.

After all, this mandarin duck ruler is not made by a craftsman, but made by Song Sanyuan, and it has the advantage of being sung by Huanqiandu Yushi Xinzidu!

Huan Ling's letters were too long and were only popular among literati, but this set of "Parrot Song" spread to the streets and alleys, and people who sold vernier calipers could sing a few lines of "Parrot Song".

And when his tunes were being sung all over the capital, one after another secret scriptures were also sent to the palace from the northwest border.

In the past few months at the border, he witnessed with his own eyes that the generals at the border occupied the land for their own, turned the generals into private soldiers, paid nothing, invaded the land of the army, and forced the soldiers to cultivate it for them.And when he was inspecting Datong, he also encountered Dalu raids several times. He saw with his own eyes that the local city guards fought cowardly and allowed the captives to plunder the people and the imperial pastures outside the city.

He urged the soldiers repeatedly to lead the troops out of the city, but there were still those who were afraid of fighting, those who were talented and would be defeated, and those who couldn't find any weapons and armor in the warehouse...

In frontier forts, fortresses, and inhabited acropolises and county towns, there are few garrisons who dare to fight and are able to fight. On the contrary, there are quite a few ordinary people who organize bow and arrow clubs to fight against the enemy with guns, sticks and bows and arrows.

There are still bloody people, but why can't bloody soldiers be recruited?

He hunted on behalf of the sky, and he was responsible for the expectations of the emperor. The livelihood of the people at the border and the people in the Central Plains cannot be allowed to allow those incompetent generals to control the local power.When the captives attacked the right guard of Datong, he exercised the authority of an angel and dismissed Ma Cheng, a cowardly guerrilla general who did not dare to fight when the enemy attacked.In addition, his deputy general Fei Yu, commander Xi Yu and others led the army on his behalf, and deployed armaments in Chishaner, Maoerzhuang and other places to stop the raid of the captives.

Ma Cheng... also has the surname Ma.Although he and Ma Shangshu have long been relatives in Wufu, they also have the friendship of the same clan.

Xintai Emperor looked at Mi Zhe, his emotions and anger were not visible, he only narrowed his eyes slightly, and said: "He is very courageous, he dares to depose the general as a censor, and he is not afraid of offending powerful families."

Wang Fu, the chief eunuch who was serving the salary beside him, said with a smile: "Huan Yushi has His Majesty's backing behind him, who is he afraid of? According to my slaves, if he is not courageous, how dare he take on the enemy and fight, and how can he pick out the good ones?" General, keep the captives out of the pass? Didn’t your majesty use him to inspect the capital because he was brave enough to do something?”

Emperor Xintai gave him an annoyed look: "You know a lot."

Wang Fu hurriedly knelt down to admit his mistake, which made the emperor smile slightly on his serious face, and waved his hands and said: "Get up, I never said that I would punish him, look at what you said to him. But his body He is the brother of Princess Zhou, and now he is joined by Yushi, a young man in his twenties, so he is tall enough."

You can't add grace to yourself, it's better to thank your parents.

Emperor Xintai glanced at Wang Fu and asked, "Has his parents passed away?"

Wang Fu quickly replied: "Your Majesty, it has been eight years since his father passed away, and his mother has also passed away for six years. After the fulfillment of filial piety, he is just catching up with the Enke in 20 years..." It was only after the draft that she became Princess Zhou.

Wang Fu only picked what he could say, but Emperor Xintai suddenly asked: "When his father left, was he ever forty?"

No, his father was only 37 years old when he passed away. He passed the second-class Jinshi examination at the age of 27. After entering the court, he was a concubine for three years, and after the palace was dismissed, he became a censor. He died of illness while in office.

Emperor Xintai sighed "poor", and Wang Fu also sighed: "No, Yushi Huan was not young when he lost his relatives, and he was not a child who could not be separated from his parents' arms, but who would not want their parents to be safe and healthy?" , the sons and daughters will have long-lasting love at your knees."

Emperor Xintai looked down at his hands—the palms were red, hot to the touch but still dry, and now he often felt dry and hot, with dry mouth and red eyes, and sometimes groggy.Since the Taizu, the emperors of this dynasty have rarely lived a long life. I am afraid that he is not someone who can look forward to prolonging life for a long time. Huan Yushi's parents are only in their thirties and have passed away, but he is over forty this year...

The Ma family was so eager to fight for power, and he dared to promote and appoint private individuals at will. After a hundred years, how would Huier be able to control the people of the Ma family?Although Huan Ling is capable, Xueshi Huan is a bit attached to power, and he doesn't know what he will do at that time. With only a capable child in the Huan family, can the Ma family be checked and balanced?

He thought about it for a while, then felt a bit of a headache, rubbed his forehead and said, "How many items did his father give away? Let's go up to another level. Let the military department be transferred to the capital to go out and guard, and ask Huan Ling to send the gift immediately." The person surnamed Ma and other people who are afraid of war were escorted to the Dali Temple in Beijing Jiaotong for questioning! How could the Ministry of War choose such a person as a guerrilla general stationed in such an important place as the right guard in Datong... Wait for Ma to explain When you return to the capital, you have to investigate carefully."
