Datang: My apprentice is Li Chengqian

Chapter 222 Li Shimin's emotion
Li Shimin is the son of heaven, and it stands to reason that he has enjoyed everything he should enjoy.

However, this is the first time that the sofa has appeared. Li Shimin's status is very noble, and he has never sat on it before.

Although the carriages he rode in before were all crafted from fine wood, the interior also looked magnificently decorated.

But the hard seat has nothing to do with comfort.

It's not like now, the whole person is sitting on the clouds and floating.

"This sofa is really strange, it looks ordinary, but it is unprecedentedly comfortable to sit on.

It can be placed not only on the carriage, but also in other places, right? "

Li Shimin moved his buttocks, found the most comfortable position, and then half-paralyzed on the sofa, talking to Qin Xiedao.

Li Junxian and Wang De on the side also sat down cautiously.

"Yes, a sofa can be placed on the carriage, and it is also possible to place it in the imperial study and other places.

However, this sofa not only uses a lot of whale skin, but also the spring inside is very difficult to process, so the cost is relatively high, and it will take some time to popularize it on a large scale. "

Spring is a very important thing in industrial development.

Although the springs used in the suspension are still difficult to make, it is still no problem to make some simple springs for the sofa.

At most, the life of these springs will be a little worse.

"It's more comfortable than sitting on any hu stool, and it's also more comfortable than those grand master's chairs in your house."

Li Shimin enjoyed talking to Qin Xiedao.

Qin Xiedao very low-key produced a batch of new tables and chairs in the Qin Mansion, which also attracted a group of people's attention in Chang'an City.

People who have tried the effect still think it is very good, so whether it is in the palace or in the homes of some generals, it has begun to popularize.

Many people think that such a good business, why didn't Qin Xiedao take him out alone?
Opening a furniture shop, isn't he good?

But you have to know that there is no concept of patent protection these days.

You create a new table, and others can imitate it immediately.

If you sell it at a high price, who will buy it from you?

But if you sell it cheaply, what money can you make?

There are many students in Chang'an City who can make money, but the threshold is very low, and there are very few businesses where anyone can make money.

It is obviously unrealistic for the Qin family to earn money for tables and chairs in order to be comfortable.

So after Qin Xiedao made those things for his own convenience, he didn't let people produce them on a large scale, let alone set up workshops or shops.

"The main purpose of the sofa is to make people sit comfortably, but this thing is too soft, if you sit here for a long time all day long, it will damage the waist.

Your Majesty can consider putting some sofas in the Tang Palace, but you can't sit on the sofa for a long time all day long. "

Qin Xiedao didn't want Li Shimin to settle accounts with himself because of his backache after sitting on the sofa for several months.

"What you said is also reasonable. There is a standing posture for standing, and a sitting posture for sitting. The rules set down by the ancients still have some usefulness and reason."

Li Shimin was just thinking about popularizing sofas in the Datang Palace, but he heard Qin Xiedao's point of view, and immediately felt the truth in it.

"By the way, Your Majesty, do you think this carriage is more comfortable than the previous one?"

The sofa is the best, but in the end it depends on the performance of the entire carriage such as shock absorption.

Otherwise, every car factory in the future will simply spend money on seats.

"Judging from the current situation, sitting in this four-wheeled carriage is still very comfortable. You can ask the driver to increase the speed, and then feel how fast it is."

Li Shimin said expectantly.

However, before Qin Xiedao could say anything, Li Junxian couldn't help it.

"Your Majesty, this carriage is already very fast, and it will not be safe any faster."

"What? Already very fast?"

Li Shimin looked at Li Junxian quite differently, and then stretched out his hand to open the curtains in the carriage.

What caught my eye was the trees and buildings flying backwards.

In just a short while, the carriage had left the Datang Palace and was speeding along the official road.

But he obviously felt that there was no particularly big vibration inside, thinking that the carriage was just moving forward slowly.

This situation is a bit different from what he imagined.

"Xiedao, how did you do it? Why is the speed of the four-wheeled carriage so fast, but there is no particularly large bump in the carriage.

Even if it is the carriage I rode in before, if the speed of the carriage reaches the current level, it will be a bit uncomfortable to sit in it.

Logically speaking, wouldn't the four-wheeled carriage be more bumpy?

Otherwise, everyone would have replaced all the carriages with four-wheeled ones. "

Li Shimin still has a good understanding of some things, and he can get to the point when he asks questions.

"Your Majesty, don't the ministers of the DPRK and China feel that they need a more comfortable and stable carriage.

In accordance with this spirit, I came up with some solutions after sleeping and forgetting food, so I have the current four-wheeled carriage. "

When Qin Xiedao spoke, although he was a bit understated, Li Shimin really believed it.

Such an excellent carriage in such a short period of time.

Unless it happens to have been in production before, otherwise it is really possible to forget food and sleep.

"This four-wheeled carriage is more comfortable than a two-wheeled carriage. What is the fundamental reason?"

Li Shimin, who is very studious, wants to find out the specific situation.

"The reason is actually very simple. Our craftsmen have installed a shock absorption system for each wheel. With this shock absorption system, most of the vibrations that the ground feeds back to the wheels will be filtered out.

Only a small part that cannot be filtered will be passed to the compartment.

And we installed a sofa in the car, and people sitting on the sofa can further reduce the vibration brought by the car.

Under this dual function, the performance of the four-wheeled carriage in the future will naturally have an extraordinary improvement. "

This stuff is no secret.

Even if Qin Xiedao didn't say anything, Li Shimin would know sooner or later.

Besides, there is no need to hide Li Shimin from anyone.

"Problems that have been unsolvable for hundreds of thousands of years have been solved so quickly in your hands. Xiedao, you really can always bring surprises to people."

Li Shimin was very emotional.

At this moment, he felt that it was a very correct choice to agree with Li Chengqian to go to Qin Xiedao to study every few days, and even to follow Qin Xiedao half of the time every day.
