The Datang Daily is now a major newspaper with more than 200,000 copies sold nationwide.

Whether it is the articles or advertisements on it, they are often eye-catching.

In the era without the Internet and TV, the power of print media was definitely very huge.

Imagine the power of paper media in the 1990s, and everyone should have a little feeling.

That was the era when TV and radio were already available.

"Sister Zixia, look at this warm-hearted thermos bottle. It is said that boiled water can keep warm in one day and not cool down.

Didn’t you say that we women cannot drink cold water often? Especially when menstruation occurs, your stomach will hurt when you drink cold water.

In the past, if I had menstruation, I didn’t dare to go out casually and could only stay at home. It was really inconvenient.

But if you have this hot water bottle, do you just put a bottle of hot water in the carriage when you go out, and don’t worry about not drinking hot water for a day?”

Sisi happily came to Zixia with a copy of the Tang Dynasty Daily.

The Zixia garment workshop they are now running is already a relatively famous garment workshop in Chang'an City, and it has been a successful entrepreneurial success.

"Can there be a thermos bottle in this world that does not allow hot water to cool? It's unlikely."

Zixia curiously put down the busy brush in her hand. She was designing a new set of robe skirts.

"Isn't it normal for those craftsmen in the hands of His Royal Highness to make some things that no one has seen before, or even things that everyone thinks are impossible?

I have also seen Dai Quan. He is the top craftsman in Chang'an City. It is said that His Royal Highness directly distributed the house to him in the Workshop City."

After hearing Sisi's explanation, Zixia immediately gained interest and confidence. She took over the Tang Dynasty Daily in Sisi's hands and started reading it carefully.

"If this warm-hearted thermos is really as good as what is said in the advertisement, no, as long as there is half of what is said in the advertisement, it is our gospel.

We can buy it at the Treasure Pavilion tomorrow. Let’s buy two and try it out first. If the effect is good, you can buy more and put them everywhere.”

Although everyone is still more honest in advertising these days, gradually, some exaggerated statements will inevitably appear.

Zixia, who has suffered losses, obviously also believes that the Warm Hot Water Bottle is not necessarily as good as the advertisement described.

"Well, I must go and take a look tomorrow. This thing is worth it even if it is a little higher."

...

"Is this the thermos bottle made by Dai Quan? It doesn't seem like anything special. It can actually keep the hot water heater insulated. It's really amazing."

As a child today, Li Shimin naturally didn't need to wait until the Zhenpin Pavilion started selling thermos bottles before arranging people to buy them.

Li Kuan directly sent someone to send 100 thermos bottles to the Summer Palace.

It seems that the cost of these 100 thermos is not expensive, but it is actually not expensive.

The most important thing is the advertising effect here. Even if you want to make up for it with money, it is impossible to make up for it.

"I have confirmed that the thermal insulation effect of this thermos bottle is really good. Normally, it can still maintain a very high temperature within half a day.

Even after a day, it won’t be completely cold cut, it’s really easy to use in winter.”

Li Zhong’s work really requires caring for everything and taking care of everything.

It is not easy for him to work with Li Shimin safely for more than 20 years.

"I look at this thermos bottle. The bamboo shell on the outside should have nothing to do with insulation, right?

The inside looks like glass bottles, and there are also many glass bottles in the Summer Palace. I didn’t find them to be insulated.”

Although Li Shimin is already old, his curiosity is not small at all.

This kind of thing that goes beyond his past cognition can always attract his attention.

"I also had this question at the beginning. Later, I went to ask Dai Quan, the inventor of the thermos bottle, and basically understood this principle.

Speaking of which, the launch of this thermos is very closely related to Guanshishan Academy of Physical Sciences.

At the beginning, the Academy of Physics discovered the phenomenon of vacuum, and conducted various analysis of the air in the environment we live in, and also speculated that the heat in the vacuum could not be transmitted.

Although this thermos bottle is made of glass bottles, the glass bottle is double-layered and is vacuumed using a special method in the middle.

In this way, after the hot water is filled with the first layer of glass bottle, it is difficult to conduct heat to the outer layer of glass bottle through vacuum, achieving a certain insulation effect."

Although Li Zhong’s explanation is a bit obscure, Li Shimin, who has developed over the years, has heard of many things about watching Shishan Academy.

So he probably understood what he meant if he didn't understand.

As for the deeper principles, he doesn't need to figure them out.

As long as you know that this thing is made using normal scientific principles, it is not a mess, that is enough.

"Kuan'er has been watching Shishan Academy and stressing that students should apply what they have learned. This time the thermos is also a product of applying what they have learned."

"Yes, in addition to vacuuming, the successful production of this thermos bottle is also related to the fact that it is coated with a layer of silver film on the inner wall of the thermos bottle.

This can be regarded as processing using the scientific principles discovered by Guanshishan Academy."

Li Zhong further added.

In order to digest these things, he felt his head hurt.

"Silver film? This thermos still requires silver? Wouldn't it be very expensive?"

In Li Shimin's mind, he naturally hopes that the thermos can enter thousands of households, because it is obvious that every household has a demand for this thing.

But now it is glass and silver film, and nothing is something that ordinary people can consume.

The things that are finally made will definitely not be cheap.

"The specific price has not been announced yet, and the Treasure Pavilion will start selling tomorrow, but at the beginning, the price of the thermos will definitely not be cheap.

However, I heard that they have launched two styles of thermos, one of which is high-end, with better insulation performance.

Another one is a slight difference, but it can also meet basic needs.

In this way, the prices of the two products are different, which should be able to meet the needs of some people."

"Look back and pay attention to this matter, see how the sales of thermos bottles are and how everyone's feedback is.

If possible, see if the hair can reduce the cost of the thermos bottle a little further so that more people can afford it.”

Li Shimin loved the people as much as his son. Although these words were a bit exaggerated, he was more friendly to ordinary people, which was rare among the emperors of all dynasties.

Whether his love for the people is for political purposes or his feelings from the heart, this is no longer important.

Everyone only looks at the results.

...

Xiang'er is the old man next to Li Kuan.

When Qing'er was too busy, she, Xing'er, and Jiuzhao Xingxiang were all considered Li Kuan's personal maids.

After the treasure pavilion was opened later, Li Kuan arranged for her to be responsible for the affairs of the shop.

To be honest, Xiang'er's name is still well-known in the Chang'an City business district.

All kinds of luxury goods, as long as they are sold in the Tang Dynasty, can basically be found in the Treasure Pavilion.

If a business from another place, especially a person from a foreign country, wants to buy some good things, it is nothing wrong to go directly to the Treasure Pavilion.

This time, the warm-hearted thermos bottle was naturally first sold here.

Seeing the benefits of thermos and advertisements from Datang Daily, Xiang'er, who has experienced, already knows that today's sales will definitely be very popular.

So yesterday she tried hard to send more products from Cui Gin workshop, but don’t sell them today and it’s out of stock.

"The entry-level version is 9999 Tang Yuan, and the deluxe version is 2999 Tang Yuan, and the Xianger girl, can you still raise the price appropriately?"

Early in the morning, all the staff from the Treasure Pavilion were in place.

Xiang'er, the shopkeeper, is no exception.

"Ninety-ninety-nine Tang Yuan, that's ten-minus coins. The average craftsman's salary is less than ten-minus coins per year.

His Royal Highness the Crown Prince hopes that our thermos can enter thousands of households, so he does not set the price too exaggerated.

This is considered for future price cuts, otherwise the entry-level version will be 999 Tang Yuan."

Xiang'er still knows Li Kuan's thoughts very well.

She also knew the production process of the thermos.

The so-called entry-level version actually uses a vacuum-drained glass bottle gland, while the luxury version adds silver plating to the inner wall of the bottle gland.

Although the costs of the two are different, the differences are not very big.

After all, it is just silver plated, and it is not made of silver.

However, the price is three times different.

There is no way, the luxury version is used to fleece.

After the construction of the special thermos bottle workshop is completed, the production cost of thermos bottles with higher production efficiency will definitely drop to a new level.

The warmth effect of the thermos is expected to be further improved.

Then you can launch more styles of thermos bottles.
