In the past few years, Li Yuanjia has really come up with a lot of good things.

But if you really count them, how many things can you make money? Not to mention the curved plough and the overturned, like the iron pot, tables and chairs, it is impossible to make money at all, almost all of them are money-losing transactions!

To put it bluntly, Li Yuanjia is just making a contribution.

For example, the iron pot, if this thing is really good, it is quite troublesome, because the raw materials and smelting and casting processes are not very passable, and it takes time and money to polish it. But in essence, he is also within the reach of the technology of this era, to put it bluntly, the technical content is not high...... If the technical content was high, it would not have become popular in the Song Dynasty.

What Li Yuanjia can do is to make the popularization of stir-fry a little earlier.

Therefore, if the craftsmen of Han Wangfu can do it, other craftsmen will definitely be able to do it, but it may be less efficient and more costly, and it will take a longer time to "research and development".

As for the tables, chairs and benches, they are even less technical, and all that is involved is the size of the brain hole and everyone's living habits.

The same is true for curved ploughs and overturned cars, and it is not difficult for carpenters to imitate them.

So in this era when there is no patent law, if Li Yuanjia really wants to make money with these things, he can only use his status as a prince to suppress those who dare to imitate.

But in this case, it depends on Li Shimin's attitude.

Therefore, Han Wang, who has no interest in making money, is naturally impossible to stop others, and even generously takes out his own technology to share it, and uses it casually.

If you want to say that the technical content is high, it is still distilled spirits, improved papermaking, and movable type printing, but these things......

Anyway, in Li Yuanjia's opinion, it would be good if he could not lose money.

Needless to say, movable type printing, Li Yuanjia even doubted whether he could see the money back in his life; As for distilled spirits, in the era of small-scale peasant economy, the only customers he could think of were the nobles and wealthy families in Chang'an and Luoyang, because others couldn't afford it at all! Considering the taste of high-grade liquor and the habits of people in this era, Li Yuanjia felt that it would not be so easy to make Tang people fall in love with spirits.

If there is hope of making money, the blank paper may be counted as one.

The quality is good, the cost is low, and it can still be earned more or less. But again, Datang is now so populous, and there are only so many people who need paper every day, how many pieces of paper can you expect them to consume in a year? It's okay to make less, tens of thousands or even hundreds of thousands of pieces a year, Hanwang paper will definitely become the representative of the top white paper in the Zhenguan period, at least the dignitaries will definitely be willing to use it, but if you make more......

Unless Han Wangfu can create a sales channel covering the whole of Datang, losing money is a certainty!

But with the traffic conditions of these years, do you want to cover the whole country?

Funny?

The only thing Li Yuanjia dared to think about was actually a Chang'an, a Luoyang, and a Luzhou. Chang'an and Luoyang are because the cities are big, there are many powerful and wealthy people, and the cost of laying sales channels is not high, and Luzhou is purely because of his younger brother Li Lingkui.

Therefore, on the side of the paper workshop, Li Yuanjia's principle is not to lose money......

In fact, the things mentioned above are all the same situation, as long as you don't lose money, or the loss is not too much, Li Yuanjia can accept it.

And the same is true of the cotton.

If you want to replace silk and linen with cotton, the difficulty is not ordinarily high, even if the Tang Emperor strongly supports it, the promotion of cotton may have to be ten years! Therefore, even if Li Yuanjia made a loom with high efficiency, what was the use? Not to mention the impact of cotton planting on food production, has the consumption power of small-scale farmers been considered?

In this way, in fact, the money earned for Li Yuanjia is the same!

Thirteen incense!

Thirteen incense is launched at a better time, just when the iron pot stir-fry is popular in Chang'an and Luoyang City. After all, it is no longer the first few years of the founding of the Tang Dynasty, and although the extravagance among the powerful and wealthy businessmen has not yet flourished, the pursuit of food has also begun to rise.

In addition, spices are not easy to deteriorate, and they could have been used as currency in this era, so Li Yuanjia saw the opportunity to make a lot of money......

Therefore, in Li Yuanjia's heart, he has made so many things, and what he can really make money, or can make money in the future, is nothing more than those few things, such as thirteen incense, such as glass, and then sea salt and tea.

Thirteen incense has been earned, and it is a hammer deal.

When several kinds of thirteen incense appeared on the market in Chang'an and Luoyang, and the taste was not too bad, Li Yuanjia directly ordered it to be terminated. Except for making some for my own use every year, I don't plan to sell it to the outside world.

Seawater drying salt, Li Yuanjia just plans to push it, and he doesn't plan to make money in the future, at least not for a long time. Because he knows the importance of such things,

So there are actually two things that Li Yuanjia really dares to touch, one is tea, and the other is glass that has not yet succeeded.

Merely......

In this year, tea has just entered people's attention, and there are very few people who can enjoy it, that is, the scholars in the south and the monks in the temple. Even if Li Yuanjia works hard to promote, I am afraid it will take decades to cultivate everyone's habit of drinking tea.

So tea, like spirits, Li Yuanjia is counting on making a little money from the barbarians.

After all, only the glass that is still under research and development is what Li Yuanjia can make money in his heart.

And it's something that can make a lot of money!

Glass ornaments and glass containers are all trivial things, because they are not necessities, and they may not be able to compete with pottery and porcelain, so the key is that Li Yuanjia asked Han Cheng to develop the mirror that they have begun to develop, which is a big gold mine in the future.

When the time comes, as long as the confidentiality measures are taken well, who can solve the mystery?

The next step was to monopolize the market of Datang, expand production capacity, and sell mirrors to Tibet, Turkic, Korean, Japanese and other countries, and then sell them to Europe through Arab merchants......

"Huh? Why do you want them to sell it? ”

When he thought of this, Li Yuanjia suddenly frowned, and a thought came to his heart: "Mirrors are small in size and expensive, isn't it just the best commodity to open up foreign trade?" Wouldn't it be a great opportunity to organize a horse convoy at that time, and if possible, maybe a fleet of ships in a few decades, and the land and maritime Silk Roads go hand in hand? ”

After thinking about it, Li Yuanjia's entire face began to glow......

……

The ghost weather in Beijing has cooled down too quickly...... Cold, headache, I feel very messy in this chapter, let's watch it.
