At the beginning, Fan Jingjing had an idea in her heart, and she couldn't wait to execute it.

But this kind of decision-making is the most dangerous.

What's more, she found that there were too many goals to implement, although each one was a good plan and a good decision, but there were not enough people to execute it, and the progress would be slowed down in the end.

As a result, a lot of things are going on, a lot of things are being spent, but very few are getting results.

It's the hardest thing to do to cultivate trustworthy people.

The more people in the manor, the more people you can trust, but without personal contact with these people, these people can't be sincere.

When you are far away, it is naturally impossible for people to be obedient to you.

As the distance gets closer, she may want to get something more and behave differently.

There must also be a moderate development of the story and the manifestation of kindness.

Fan Jingjing didn't have enough manpower and enough people to trust, so she was only able to do half of the things, or slow them down, and there was no way to complete one of them.

Completing one can bring a lot of changes to Datang, and the Fan family manor can also benefit from it.

Later, Fan Jingjing thought that these things could be recorded, so she was very active in finding a wooden board to engrave, paper and pen are more expensive than eating in Datang.

Expensive wood in the era of science and technology is a bargain in Datang.

People who don't have money will find a way out of life.

When Fan Jingjing finally made a usable paper and could easily get the paper, she began to write and draw on the paper, writing all his thoughts on it, and reading and supplementing it at any time.

Moreover, Fan Jingjing also made these papers into small notebooks and burned wood into charcoal to write.

After all, Western quill pens also need ink, and it is still not very convenient to carry ink with them, after all, Fan Jingjing does not have the habit of using child servants.

Although when the original pen was first produced, it seems that it was because of the use of ink that was carried with you.

But the ink that you carry with you can easily tip over, and there is not a very good container for liquids in this period.

As for the charcoal itself, it is much easier to carry a solid than a liquid when it wants to carry it on the body.

At this moment, Fan Jingjing thought of the method of food preservation, only if food can be well preserved, it can be transported over long distances.

Only by being able to have the basic conditions for long-distance transportation can we talk about how to make products cheap.

The production of canned food is to solve the problem of food preservation, transportation and production of scientific and technological products.

Canned food production has also undergone many improvements to make it better preserved and less prone to revelations.

At the beginning, the production of canned food was to add sugar to the water to fill canned pineapples, but in this era, if you want to make metal cans, the cost is too high.

The cost of the food inside will increase many times, although the price of the food is high, but the price of what should have been eaten is even more sky-high, and the most important thing is that there is no way to obtain it.

Without the power of the state, it is very difficult to transport lychee, a delicious fruit, to Chang'an.

Prices have left the place of origin, risen a thousand times, and there was nothing wrong with the Tang Dynasty.

In the Tang Dynasty, traffic was not only about the distance, but also about the various peculiar road conditions on the way.

The road is really walked out by people, and there are many rivers, and there may be people who usually assist in crossing the river, but crossing the river is not only a matter of speed, but also a problem of transportation.

For every river crossed, a problem had to be solved.

For Datang, building bridges on each side is a great project, and it can be said to accumulate good deeds.

The point is that the state does not have the funds to build bridges, so most of the time it must be made manually, and the workers are not yet professional workers.

In order for the army to cross the river, it is necessary to build temporary bridges with the strength of the army, but these bridges are generally not used for long.

The army pursues speed, and even when crossing the river itself, several people will die.

Because of the difficulty of transportation, if you have the ability to solve the problem of transportation, send the sweet fruits from the south to the north, the price will not rise, especially the lychee that changes color in two days and tastes in three days.

Since ancient times, lychees have been a very high-priced product in the north.

When the ordinary lychees in the south reach the north, it can be said that the price is higher than a thousand gold.

What's more, salt and sugar are both nutrients that the human body needs.

However, in the Tang Dynasty, neither sugar beet nor sugarcane were sent to the north in large quantities to be sold, and even sugarcane in the south was not recognized by anyone who could extract sugar.

Most of the so-called sweetness comes from fruits, not to mention products with such a high sugar content as lychee.

The people of Datang are very particular about strangeness, and being able to eat things that others can't eat represents status and nobility, so. Lychee has a lot of limitations, so it becomes a representative of noble products.

Being able to eat lychees means that your status is very high, and you have enough money to spend it.

Canned, although it is necessary to peel the lychee and put the pulp in the can, the sugar water can increase the sweetness and preserve the lychee well.

This product of canned lychee is definitely more worthy of people's enjoyment than fresh lychee, and the price will be much lower. It can become an item that ordinary people can use, and in fact, lychee will be a fruit that people love to eat, even if it is not noble.

And more importantly, the origin of lychee is basically the same as the origin of sugarcane, and sugarcane can cure sugar, if sugarcane is made into sugar to make canned lychee, and then sent to the north. The cost is not very high.

Even if the sugar itself is transported to the north, after being made into sugar, it is not easy to spoil, it is easy to preserve, and the volume will be reduced, which can increase the efficiency of transportation.

That is, to reduce shipping costs.

If the taste of lychee is kept as it is, or even better, then the Tang Dynasty people who pursue fresh and delicious will be even more eager to do so.

Money, if there is too much, must be spent, if it can be spent to buy face, buy enjoyment, buy things that others can't buy, for the rich, this is the real use of money.

He doesn't know how to do the math, if he buys a lychee, he can buy two baskets of plums.

For him, plums grown in the north are really very cheap, and there are few people in the north who have never eaten plums.

So when he eats plums, he has to hide from where no one is there, and when he eats them for others to see, he has to eat fruits from the south.

Only by eating noble fruits can we strive for a higher status.

They may not understand the truth, but they just come to know it in practice.

For Fan Jingjing, she just needs to know that the principle of canning is very simple, pump the air away, so that the ** object is no longer **.

In this way, new demand can be generated, new goods can be generated, and money can be made.

There is no iron can, so you can experiment with other utensils.

Fan Jingjing told the people of the Fan family manor that they must have the spirit of experimentation, and if they can't do it once, they will change the method until they achieve their goal.

If his goal is not very evil, and his methods are not evil, it is enough not to violate his conscience.

In fact, in addition to telling them to have the spirit of experimentation, she also knows that if scientists want to achieve experiments perfectly, there are many times when they have to become very evil to achieve results.

But Fan Jingjing hopes that evil things will not happen in the Fan family manor.

Therefore, Fan Jingjing has always told the people of the Fan family manor that there must be humanity.

Otherwise, these people in the Fan family manor who can get more money through brain activities will gradually become terrifying.

Man's ** is endless.

Without human experimentaics, they will cut the human body and use the human body to do all kinds of experiments, and the exploration of many problems is actually the exploration of the human body.

People are most interested in the human body.

Being able to conquer humans can get a lot of benefits.

At the very least, if the human body is studied thoroughly, medical technology can be greatly improved, and people who greatly improve medical technology will be respected in their lives.

As long as you don't mess with people you can't provoke, such as the emperor, as long as you can get good medical skills, you can get a very high social status.

If the emperor's family is healed to death, there is no way for others to save him, and the most important thing is that no one has power, and the emperor is at the same level, and all people must lie at the emperor's feet, so there is nothing to compare.

Unless he was born in a big family, and the status of this big family is very important to the emperor at the moment.

Let the emperor dare not offend, but the person who makes the emperor dare not offend will make the emperor feel very awkward all the time, which is not a way to achieve long-term peace and stability.

Because of the person who makes the emperor uneasy, the emperor will definitely find a way to solve the uneasiness in his heart.

If he was only a powerful person, and the doctor's status was high enough, others would not dare to strangle him to death.

Because a miracle doctor can't heal your family, but he can heal others.

In this case, others will protect him, protect her, that is, protect their own life.

Of course, people will only protect the doctor and not the doctor, so that if the doctor lets the family know that you are dead, no one will pay attention to you, unless you have someone else who can protect you, such as your family.

People who can heal the dead are generally less valued.

Having said that, the most important thing in the production of cans is to make a vacuum, so that the air does not go in, because the reason why time will cause the object's ** is not the fault of time, but because the object is contaminated with bacteria in the air, and most of these bacteria are good, if the oxygen is discharged, or even keep there no air inside, then the ** of time will not continue.

But in this era, it is very difficult to keep it airtight, the most that can be done is to reduce the airtightness, if you want to make a thing vacuum, the easiest way is to suck the air out, although there is no way to achieve a complete vacuum, but when the air content is reduced, the speed of the whole process will also be reduced, so when you carry out **, such as stinky tofu and other food, you must ensure that there is air in it, but the air will not be too much.

Let the air reach a certain stable condition, it will produce edible bacteria, because some bacteria are harmful to the human body, but some bacteria are not only not harmful, but can still help our digestion and absorption.

Many people will use vacuum cleaners to remove the air and use it to collect quilts and other items, but in this era, there is no vacuum cleaner, and there is no principle of extracting air.

In fact, you don't have to have a vacuum cleaner to get the air out, and you can use a person to suck the air away through a straw. A person who constantly inhales air and has no way to close the other side can easily cause failure in the work.

Since Fan Jingjing has a great interest in canned food at this moment, when a person is interested in one thing, it is easy to forget what he was worried about.

Niu Shijin writes in the theater. When the emperor watched a play in the theater and a new play was staged, it was necessary for the playwright to see how the people in the first play felt about the play, and then revise the play according to the reaction.

The emperor looked at the drama code of Chang'an, and felt that his blood was boiling, although there were only four or five people on the stage, but he seemed to see thousands of troops, and the emperor felt his blood boiling at this moment.

So Emperor Li Shimin finally wanted to see who wrote the script.

At this time, there was no theater projection, so the name of the screenwriter did not appear on the stage.

He knows that it is not only the people who perform on stage, but also the compilers of the texts.

The small world of drama is the sublimation of a person's soul.

Emperor Li Shimin, looking at the people standing in front of him, was very suspicious, every day, the emperor must see many people.

Many times, the important work of the people around him is to remind the emperor who the person in front of him is.

Although the emperor did not know each other, the other party recognized the emperor.

If the emperor can remember each other, it will make the emperor feel and tolerant.

Emperor Li Shimin found that the person in front of him was not a stranger, he had seen it before.

It's just that the number of times I've seen it won't be too much, and most of it is when I summon the minister to have fun.

The man in front of him thought that he had come to the banquet with his father.

But when meeting with the emperor, the emperor's eyes will not be on these small people, and the reason for paying special attention is that Niu Shijin is full of martial arts and courage, quite a father's style, which is different from other trousers brothers.

When the emperor summons ministers, he also needs to work, so most of his attention is with the father of the second generation of Gui.

When negotiating, many times it is nonsense, but these nonsense contains all kinds of national affairs, as for these juniors are not in their position, and I don't know if they can take over their father's work, the emperor is not very concerned.

Unless the health of the previous generation has slowly failed, it must be inherited by the next generation, because most of the heroes of the founding of the country can pass on their positions.

Yes, the second generation, most of them are unusable.

The descendants of meritorious heroes will generally be the key objects of appointment by the imperial court.

It's just that if you don't have the strength, you won't be sent to key positions, and most of them are placed in dispensable places.

There is generally no chance of being tested.

Chang'an will prosper, often not because of the function of the first generation, but because of the credit of the second generation who like to play around.

After Fan Jingjing joined, she brought more common culture.
