Many inventions are born on the whims of people, and they do not necessarily have to use very high technology, but people have not thought about it before, or thought about it, but they have not had time to create it, or it spread, or it has disappeared in a war.

These inventions can often be easily done by hand, but the efficiency is a little lower.

For inefficiency, people in ancient times were basically used to it, and as a result of too much work, they would not have time to use their brains to invent a lot of things, because every creation will take a long time to circulate, and many people only think about what they can use to create it, and they have never thought about conveying it.

Because there is no way to record the life of this era with various videos or voices, but in this era, many people do not understand words.

Whether video and voice can be developed, Fan Jingjing doesn't know, at least, she wants to train a group of literate people to study.

The words of Datang restrict the possibility of knowledge transmission.

There is no public circulation.

It's really too closed, and there's no way to let you know what you're doing anytime, anywhere, far away.

The construction of the telegraph system may have to use special means, wireless telegraphy, and the possibility of wireless transmission, Fan Jingjing must think carefully, but this span, will not be too advanced.

In fact, in Fan Jingjing's mind, through the principle of wireless transmission, she only needs to establish a base station at a certain distance to complete wireless communication.

However, in this aspect of science and technology, Fan Jingjing's mind is not very full, and it is difficult to get a short-range radio.

In any case, any kind of research, as long as it is invented, is a great invention.

Able to advance life and go further.

There are two sides to science and technology, and Fan Jingjing knows that these inventions will definitely be used in places that hurt people.

She doesn't understand why some people can really have no conscience for the purpose of hurting others, is it really all for life?

Or is it an international confrontation that has already begun in this era?

Sun Erlang has no resistance to investing in business, but he knows that many people who are based on production have some opinions about businessmen, but whether becoming a businessman will cause others to backlash, he only knows that people have to deal with them, including some businessmen who originally held good intentions, in fact, this is also a kind of speculation.

But making money for the Fan family manor, that is, making money for yourself, everyone should be able to agree with this.

It's just that they may be worried that if they become merchants, will Fan Jingjing, who became a lord, become the object of abandonment by the lord group?

The Scholar Group, after all, is different from the group that has made military contributions?

Although merchants can be rich and rival the country, because they do not show enough patriotism, they often become the target of the imperial court.

In fact, because the imperial court's attitude towards merchants has always been very bad, it is even more difficult for these merchants to cultivate a heart of love for the imperial court.

The state and the court may be completely different things in their minds.

Fan Jingjing didn't know if there was really no country in their hearts, or if they couldn't see so far away.

But Fan Jingjing feels that it is a good thing for the people of Datang to develop a business territory.

Do not suffer from widowhood, but suffer from unevenness.

There is absolutely no shortage of materials in Datang to the point that people will go hungry, but there are livestock who have no way to slaughter the meat, and every meal is distributed to everyone to eat.

There is no way to put a cow in the refrigerator, and the meat will spoil quickly, even if you find a way to make bacon, or bacon, it will take a while, not to mention that in this era, there is not so much research on the preservation technology of meat.

At this time, there are many preservation techniques that have been made, and they will break down halfway.

All techniques need time to be slowly honed, and a method is researched, and it will not break down if you do it according to this method, after all, the research method at this time is not a scientific research.

The ability to summarize the reasons for failure is not enough.

If you can find out the reasons for each failure, you can slowly accumulate experience and move forward on the road to success.

Only a few people will be interested in studying this thing, but people who have the spirit of research are generally people who have the ability to record, and these people are detached from the lives of ordinary people.

Because in this era, people who have the ability to write, generally the so-called upper class, they can eat without having to do their daily work, and they have a lot of land to enjoy, unless their ownership of the land changes, or they fail in the struggle with others. But he did not die and live on the streets, becoming someone else's worker.

As long as they are not mortal enemies, most people will be treated kindly when they meet people who have the ability to read and write, at least they have a higher treatment than those who can't read and write.

In the era of science and technology, because everyone can read and write, words suddenly become not so precious, and people who read books think that they are not great, because all things are precious when they are insufficient, and when they are excessive, people will begin to be picky about wanting better words or better personalities, so they will hire him as their own employees, and even the requirements for age have become more.

In the Tang Dynasty, even if a scholar was seventy or eighty, as long as he could apply, many bosses regarded them as guests, and even lived in their homes, and their servants were responsible for taking care of their daily food and drink, as long as they worked hard and could be worthy of their treatment.

Relatively speaking, the money earned in this era is really not much, because most of the costs are actually very high, only the labor cost is very low, so when people use people, there will be a very big gap, the salary of talent is high, but the salary of no talent is low, there is a very big difference.

Like Fan Jingjing, it is a very rare thing to give many people a salary that is enough to live.

Not only are they enough to live, but even some of the money can be used to save money for investment, and even buy some daily necessities, which greatly meets the needs of their daily life, of course, if they want to eat, drink and have fun all day long, and not save money, it is just enough for his daily chic, and there will not be much surplus, because Fan Jingjing also knows that the reason why the salary in this era is so low is because every job needs many people to do. Naturally, the salaries of these people are not high.
