One day, Han Du was accompanying An Qing to look after his son in the yard. A child of two or three years old is the time when people feel bored when they are full of energy. Just now, Han Du was pestered and played with by his son, which made Han Du, who was not yet thirty years old, feel tired, weak and exhausted. Fortunately, a maid saw that the kid's attention was drawn away, allowing Han Du to escape.
Lying lazily on the chair, Han Du turned his head to look at An Qing, who was drinking tea elegantly, and said, "Should we find an enlightenment teacher for Zhong'er? It's not an option for him to play like this all day long."
The main reason is that he keeps pestering me all day long, and our body can't bear it... Han Du silently cursed in his stomach.
An Qing glanced at Han Du with a smile on his face, as if thinking of Han Du's miserable state being tortured by his son, he burst out laughing, leaning forward and back with great joy.
Han Du didn't know what An Qing was laughing at, but he just felt that she had bad intentions. He couldn't help but darken his face and said seriously: "I'm serious about you, why are you laughing?"
"No, no..." An Qing couldn't help but glance at Han Du again, waving his hands and shaking his head in denial.
After finally calming down, An Qing smiled softly and said: "Is it too early for enlightenment now? I remember when I was a child, I was six or seven years old, and my father asked my husband to enlighten me. My son is still young now, Let him play for two more years."
That's two more years of playing with me... Han Du couldn't help but complain in his heart.
No, I have to find something for my son to do, otherwise he won’t torture me until I have a nervous breakdown? Han Du's mind was running rapidly and he was thinking hard.
Suddenly, Han Du came up with an idea: "My son doesn't need to be enlightened yet, but we can also let him learn to read first."
"How... how can you read without enlightenment?" An Qing was a little unable to understand what Han Du meant, but she knew that Han Du's ideas were always unconstrained and unimaginable.
So with a bit of curiosity, his beautiful big eyes flashed and he looked at Han Du.
Han Du quickly gestured with his hands, "Look, doesn't my son like all kinds of animals? We can draw various animal patterns on the paper, such as chickens, ducks, geese, dogs and cats, and add text. In this way, my son will read When these chickens, ducks and geese play together, they will subconsciously remember the relevant words. As long as we teach them intentionally, we may be able to help them learn to read early."
"Is this...useful?" It was also the first time for An Qing to hear such a novel thing, and he felt a little incredible.
"Can you please remove it? It must be useful." Han Du turned over and stood up, ready to do whatever he thought of. Paper is easy to find, and Han Du plans to use high-quality rice paper. Find a few more painters to draw the appearance of various objects.
Before Han Du could do anything, the maid came to report.
"Master Hou, Mr. Fang is here."
The Mr. Fang the maid refers to is Fang Xiaoru. This guy is becoming more and more refined now, and his movements have the demeanor of a Confucian master. The maids in the mansion did not dare to call him by his first name, so they addressed him as Mr. Fang.
"Fang Xiaoru? What is he doing here?" Han Du asked subconsciously.
Seeing the maid's expression of embarrassment, Han Du also realized that his question was in vain. Due to the close relationship between the two, Han Du had already ordered the people in the mansion to let Fang Xiaoru in directly without asking the reason or informing him as long as he came to see him.
"Where are they? Are they in the front hall?" After Han Du came to his senses, he continued to ask.
"Yes." Seeing that the Marquis did not blame her, the maid covered her mouth and smiled a few times, then nodded and replied.
"I'll go see what's going on first, and then I'll come back and continue thinking about how to get these things for my son." This was what Han Du said back to Anqing. After that, he strode in front of the maid towards the front hall. go.
An Qing didn't care about Han Du and just smiled and nodded when he turned around. After Han Du left, An Qing felt that she had had enough, so she got up and walked towards where her son was playing.
Han Du came to the front hall, and as soon as he entered the door, he saw Fang Xiaoru sitting upright and drinking tea inside.
The two of them were so familiar that Han Du didn't even say hello to him, but took a few steps to sit next to Fang Xiaoru, sat down on the chair, and groaned in his nose.
"I just discovered that the most comfortable thing is to be able to sit down. Even doing it for a while is much better than standing and following my son around."
Fang Xiaoru didn't even raise his head. He was still drinking the tea in his hand and responded casually: "It's pity for the parents in the world. This is why I listen to my father's words."
After saying that, Fang Xiaoru raised his eyes and looked at Han Du: "But this is not why I came to you today."
Han Du slumped on the chair, feeling that the pain all over his body had been relieved a lot, and he felt so comfortable that he wanted to lie down like this. He weakly raised his eyelids, glanced at Fang Xiaoru, sighed and said, "If you have any business with me, just tell me."
Fang Xiaoru suddenly became dissatisfied when she saw Han Du's attitude. The teacup that was about to reach his mouth was placed heavily on the table. He said angrily: "You are such a noble person and forgetful about things. Don't you remember that you are still the deputy judge of the academy?"
"I remember, why is it that the academy has lost money again? Didn't I give all the glass to the academy last time? Why is it not enough?" When Han Du heard the word academy, he was so excited that he sat upright. The body looked nervous when he saw Fang Xiaoru.
If the profits from the glass workshop are not enough to maintain the academy, then Han Du
I really can't think of any good solution other than using my own money to subsidize it.
No, it’s not impossible.
Lao Zhu is not the judge of the academy. Strictly speaking, this academy belongs to him. He should contribute, and he must do so in a big way.
Thinking about Lao Zhu's annual income of more than 40 million yuan, Han Du couldn't help but feel a little moved. With so much money, if Lao Zhu slipped a little from his fingers, it would be enough to cover the expenses of the academy.
"The academy is not short of money for the time being." Fang Xiaoru's words made Han Du look much better.
He returned to his indifferent look and asked casually: "What's going on?"
"It's because some gentlemen and some students in the academy came up with something together and wanted you to see it." Fang Xiaoru picked up the teacup again and took a sip without restraint, carefully tasting Handu's good tea.
"What is it?" Han Du rested his left arm on the armrest of the chair, leaned against Fang Xiaoru, and asked closely: "Isn't Mr. Xue in the academy? He was the former Minister of the Ministry of Industry, and he has never seen anything in his life? "
Fang Xiaoru sat on Han Du's left arm and leaned closer and chuckled: "Mr. Xue asked me to ask you to take a look."
"Oh?" Han Du touched it. Since it was something that even Xue Xiang was not sure about, it made Han Du a little curious.
"Then let's go, let's go and take a look now." Handu was quite concerned about the academy, and since he was teaching a group of students, he also wanted to see what they could make.
Han Du followed Fang Xiaoru to the academy.
After so many years of continuous construction, the various buildings in front of the academy have all been completed. Behind the academy, only a general framework has been built. Because of this, this place seems very empty. Students like to do experiments at the back of the academy.
After all, whether it is physics or chemistry experiments, fire is used. If we do it in the front building, it will be bad if the building is damaged.
Han Du pushed the door open and entered a house with large sorghum pillars. Looking at the steel frame one foot high, he felt that this thing seemed familiar.
Several people were gathered around the shelf and concentrating on discussing something. Even the sound of Han Du pushing the door open was not heard by them.
"What is this? Who made it?" Han Du walked forward and looked at the shelf carefully.
"Mr. Han is here." Several people stood up after hearing this, and one of them nodded and smiled at Han Du in greeting.
"So it's you, Sun Xian. What, is this what you created? What's its use?" Although Han Du looked familiar at this thing, he couldn't remember it for a while. Instead of thinking hard here, it would be simpler and more direct to ask Sun Xian directly.
Sun Xian was one of the first scholars to come to the academy to study, and he was not very interested in the Four Books and Five Classics. He was able to pass the exam simply because he was smart enough. On the contrary, he was very interested in exploring miscellaneous subjects such as natural laws and techniques. When he heard what mathematics, physics and chemistry the academy was going to teach, he was the first to come to the academy to study without hesitation.
The reason why Han Du knew Sun Xian deeply was because he was very good at mechanics, and among all the students, he was at least ranked among the top three. Being able to rank firmly in the top three is almost considered to be the best in mechanics among the students. Because even if a person gets first place once, there is no guarantee that he will get first place again next time.
In the last spring, Sun Xian was naturally among the best, ranking third in the second division. But later, because they were accused of cheating, most of the students in the academy gave up their official positions and became teachers in the academy.
Sun Xian had no interest in becoming an official in the imperial examination, so he was overjoyed to be able to stay in the academy, because not only could he continue to study his favorite mechanics, but he could also teach and educate people and support his family. It could be said that he was blessed with three blessings.
Sun Xian rubbed his hands and felt a little cautious in front of Han Du. However, he knew that when Han Du was in the academy, he did not show any airs as a marquis. He smiled and explained to Han Du: "A student taught by the student was more interested in pulleys. Then he asked about an idea, could he use it? The pulley block was used to create something that could carry large items. Then, the students led others to try it, and they didn’t expect it to actually be made.”
Of course... Han Du didn't wait for Sun Xian to finish speaking, and he hurriedly answered for him in his heart. Even Han Du felt a little regretful that he didn't think of this.
I have seen it more than once, the scene of an endless stream of cargo ships loading and unloading goods on the dock outside the north gate. All goods can only be moved up or unloaded manually. It is time-consuming, labor-intensive, very costly, and extremely inefficient.
You should know that it is not easy to get on the boat. Usually, a movable wooden board is put between the plank road and the boat. Even if people walk on it empty-handed, they may fall into the sea. What's more, the people loading and unloading have to carry heavy goods, so they can only move the goods one step at a time and carefully.
Thinking of the Ming Dynasty's increasingly prosperous overseas trade, the ships entering the dock every day are like blocking out the sky. The number of goods that need to be loaded and unloaded every day is an extremely huge number. If this thing can really be improved and can meet the requirements of cargo ship loading and unloading, Han Du will feel as if he has seen a huge amount of money coming towards him.
"Okay, good stuff." Han Du patted Sun Xian on the shoulder and praised loudly.
Seeing that Han Du was so happy, Sun Xian obviously agreed with what he had made. He smiled and nodded in agreement. Even when Han Du reached out to pat his shoulder, he deliberately bent down and lowered his body to make the pat more comfortable for Han Du.
Although Han Du was about the same age as Sun Xian, in this era where teachers were respected, although Han Du did not accept him as a disciple, Sun Xian himself was extremely grateful to Han Du and treated him as a teacher.
"Sir, why don't you let the students demonstrate it for you?" Seeing that Han Du was very interested, Sun Xian suggested at the right time.
Han Du nodded repeatedly, and he wanted to see how well they made this thing: "Okay, then let's wait and see how effective this thing of yours is."
"Just watch it, sir." Sun Xian smiled and bowed slightly to Han Du, turned around and said to the people next to the shelf: "Quick, get ready, let's demonstrate it to sir."
Several people have obviously tried it before, and now using this stand again is completely familiar and no stranger to it.
I saw one person hooking a huge iron hook on a stone tied up with a large hemp rope. Then only one person stood up and stretched out his hand to continuously pull the rope, and the stone was easily pulled up.
This kind of thing is not uncommon, Han Du once showed it in front of Lao Zhu. The important thing is something else. After the stone was lifted, the person started to pull up another rope. The stone did not continue to be lifted, but began to move parallel along the shelf.
"Okay!" Seeing this scene, Han Du clapped his hands happily.
Although the thing made by Sun Xian is crude, it completely agrees with Han Du's idea. As long as it is improved a little more, it will be a qualified loading and unloading tool.
Sun Xian returned to Han Du and replied with a smile: "It's good that the teacher is happy. The students are afraid that they will insult the teacher because they are not good at studying."
"No, you really did a good job." Han Du first praised Sun Xian affirmatively, and then asked: "How much weight can this thing lift?"
"A thousand pounds is definitely no problem." Sun Xian replied immediately.
"If it's a thousand pounds, it's a little less..." Han Du said to himself noncommittally.
One thousand kilograms is almost equivalent to the amount that ten people can carry once, and the efficiency is much faster than that of people. After all, for this tool, carrying goods is just one step at a time, but for people, it takes ten people to carry the goods on their backs one by one.
Sun Xian heard Han Du's words and quickly explained: "Sir, if this thing is made stronger, it can still lift two thousand kilograms."
Two thousand kilograms is barely enough... Han Du made a slight calculation in his mind, and did not continue to struggle with this issue. Instead, he said: "But your thing is still too small. If you want to really use it, If so, we need to make it bigger.”
Still young? Sun Xian looked back at the one-foot-tall shelf and didn't know what to say. In fact, he only built this thing on a whim, just to test his students' ideas, and he himself had no hope of doing anything with this thing.
"Do we need to make a lot of them?" Sun Xian was a little unsure about Han Du's intentions and couldn't help but ask in a low voice.
"Let's not talk about this for now. Let's talk about the ownership of this thing first." Han Du looked at Sun Xian with a smile, and his enthusiastic attitude made Sun Xian shiver.
"What, where does it belong? If you want it, sir, just take it." Sun Xian was extremely generous and casually promised to let Han Du take it away.
Han Du glanced at Sun Xian meaningfully, feeling helpless at his generosity. He didn't know the value of this thing, and he didn't even know how much gold and silver he had thrown away with his casual words.
tomato
Han Du felt that it was necessary to teach a dull student like himself a lesson, "Don't you know how much this thing is worth? Your family is not rich, so why don't you even ask, and just let us take it as we please? Walk?"
"This is just a shelf made of fine steel. How much is it worth?" Sun Xian said nonchalantly. In his opinion, this thing was just a little expensive for steel, but Tuolinmo got it for him, and it cost him less than thirty guan.
Thirty guan is a huge amount of money for ordinary people, but Sun Xian's monthly salary in the academy is ten guan, which is only his monthly salary for three months.
"You'd better first listen to how much money I'm willing to pay." Han Du said with a faint smile.
"Sir, just take it and use it. It really doesn't cost much." Sun Xian refused as always.
Han Du ignored Sun Xian's words, glanced at the stone that was still in the air, turned to Sun Xian and asked doubtfully: "I saw that after your stone was lifted just now, even if the rope was loosened, it would not move. Luoluo, is there some mechanism here?"
"Yes." Sun Xian answered honestly, "The student added a clip to the pulley block. Normally, this clip will not have the slightest impact on the rope. But once something is hung up, it will be hit by a heavy object like this. Pull, and the clamp will allow the rope to be lifted up but not put down. After the weight is removed, the clamp will naturally loosen."
"Yes, the idea is very clever." Han Du glanced at Sun Xian appreciatively, nodded and said:
"Although your thing is good, it still has some shortcomings compared to what I imagined. But the overall idea is right, so I am willing to give you five thousand guan to buy all the technology of your thing. What do you think? ?”
