Looking at the surprised and puzzled eyes of everyone, Hu Changan smiled slightly, walked to the pool, and explained to everyone: "Everyone, this piece of copper pipe is called a faucet. As long as you turn the switch on it, living water will flow out continuously.
.”
"And the pipes under the pool are connected to the underground drainage ditch."
"In this way, the sewage can be discharged directly from the ditch."
As he spoke, Hu Changan slightly turned the switch above.
Sure enough, a steady stream of water flowed out of the copper pipe.
After the water stayed in the pool for a short time, it quickly left the pool and flowed out from the pipe below.
When everyone saw this, they couldn't help but gathered around. Everyone looked at this trendy faucet and were so shocked that they could hardly speak.
In their entire lives, they have never seen such a convenient hand washing device.
How come the water flows out continuously with just a slight twist?
And not only that, the water can be quickly drained outside, which is so convenient!
You must know that when they washed their hands before, they needed someone to attend to them.
First, someone had to fetch water from the well outside, then pour the water into the copper basin, and then the copper basin had to be brought up.
After washing your hands, a designated person will pour the dirty water into the drain.
It would be fine if you just wash your hands normally.
But if your hands are greasy or dirty, it cannot be solved with a basin of water.
Sometimes it often takes five or six basins of water to wash your hands cleanly.
As a result, the servants and maids serving the wash hands must run back and forth, which is very tiring to watch.
But if there is a faucet like Hu Changan, there will no longer be a need for people to run around again and again!
Although there is no shortage of servants and maids in the homes of these ministers, it is naturally best to save trouble.
Moreover, this faucet not only saves time and effort, but the water that flows out is still running water!
If you wash your hands with stagnant water, you can only change the water one basin at a time. Sometimes, even after changing the water, you may not be able to wash your hands thoroughly.
But washing hands with running water makes a big difference.
If you wash your hands with stagnant water, the dirt will remain in the water.
But if you wash your hands with running water, the dirt will be washed away in an instant.
In this way, no matter how you wash your hands, you will always use fresh and clean water, which is great!
When everyone saw this, they were full of admiration.
Zhu Yuanzhang was the first to roll up his sleeves and said to Hu Changan: "Hu Aiqing, since you have installed this hand-washing equipment, I will be disrespectful to you."
"Today, I will come and try this faucet myself!"
Zhu Yuanzhang stretched out his hand and put it under the faucet.
Suddenly, a column of cool water hit Zhu Yuanzhang's hand.
Zhu Yuanzhang rubbed it casually at first, then took the soap on the side and started washing it.
Under the action of running water, the soap applied is quickly washed away.
This time he washed his hands with running water, and Zhu Yuanzhang did not feel the sticky feeling that he often had after washing his hands before.
On the contrary, after washing his hands, Zhu Yuanzhang's hands felt refreshed!
After washing his hands, Zhu Yuanzhang took the cloth on the side and wiped his hands.
Here, the only thing you can't imagine is that Hu Changan can't do it.
Service means being attentive and attentive.
Since there is a sink, natural soap and hand towels also need to be prepared.
After Zhu Yuanzhang washed his hands, he looked at the faucet and was quite satisfied: "Everyone, why don't you come and try it too?"
Suddenly, all the ministers lined up and began to experience Hu Changan's magical faucet.
Everyone was filled with amazement.
I don’t know how long Hu Changan’s brain is so long that he can come up with such magical things!
However, at this moment, Xue Xiang, the minister of the Ministry of Industry, was the first to ask: "Master Hu, I wonder what principle your faucet uses?"
"How come as soon as the valve is opened, fresh water flows out?"
As Minister of Industry, Xue Xiang has always loved studying these things.
Other ministers may have just read it, but what Xue Xiang values more is the principle.
When the other ministers heard this, they turned around one after another, waiting for Hu Changan's answer.
They also want to know how this faucet works!
Seeing this, Hu Changan also smiled slightly and said eloquently: "I installed a small water tank on the roof of this house, which stores the well water I brought from the backyard, and the water tank is connected by pipes.
Come to this faucet."
"The faucet is on the lower ground and the water tank is on the higher ground."
"When there is no valve installed, water will naturally flow from high to low."
"I installed the valve just to block the flow of water when not in use."
"When you need to use it, you just need to unscrew the valve, and the water in the roof water tank can flow directly into the water pipe below."
When Xue Xiang heard this, he quickly raised his head to look.
Sure enough, above the roof, there was a rectangular iron water tank standing steadily.
Under the water tank, there is a special pillar to prevent the water tank from being too heavy and collapsing the roof.
When Xue Xiang saw this, he couldn't help but praise: "Shilang Hu, you are really a great talent!"
"Such an exquisite structure, I, Xue, would never have imagined!"
When Hu Changan saw this, he was also modest.
This is achieved by standing on the shoulders of those who came before us, and it is nothing.
Seeing this, Xue Xiang's admiration for Hu Changan increased even more.
After inventing such a good thing, you can still be neither arrogant nor impetuous, which is worthy of everyone's style!
Even the veteran Liu Zhongzhi, who was standing in line next to him, had a stronger impression of Hu Changan.
As an old man who has been immersed in officialdom for many years, Liu Zhongzhi naturally knows what is true humility and what is false humility.
Hu Changan’s humble words just now are definitely sincere!
Nowadays, an impetuous atmosphere prevails in official circles.
Even if they only do something small, everyone still has to brag about it, for fear that others will not know that they did it.
Looking at Hu Changan again, even if he really did something earth-shattering, he still looked normal and didn't feel that it was a big deal at all.
This kind of magnanimity is probably not found in many people in the entire court!
Soon, all the ministers lined up to wash their hands.
Next, it’s time to wait for the food to be served.
Since it is a high-end hotpot restaurant, every dish served is freshly fried.
Although Hu Changan has ordered people to prepare as much as possible in advance, it still takes a while to cook the dishes freshly.
In this case, you will naturally need to wait for a while.
When the ministers saw this, they chatted for a while.
What we were talking about was, of course, the national affairs of the day.
Although Hu Changan had no right to join the discussion, he still listened while holding a cup of tea.
