The departure of Zhang Hongcai and Hongxing Academy is not a big deal for Ding Haijun, after all, including some students, that is, less than 200 people, which cannot be called a very large person for Ding Haijun, whose population has exceeded 1.8 million.

It can be said that in the entire field of education, there is no one who can be compared with him, and his gift proves that there is no compromise in Ding Haijun's education, either to leave or obey.

Not everyone is as stubborn as Zhang Hongcai, even if some old scholars are stubborn, they must also consider their children and grandchildren, Zhang Hongcai, as one of the founders of Ding Haijun's education, not only is he very prestigious in the field of education, but also several of his children and grandchildren are developing well, one of the sons, the deputy section chief of the Commercial Bureau, and two grandsons, they are also unit-level officials.

Such a position, although it is not as high as that of the Northern Song Dynasty, and even the director of the bureau is only a seven-grade, but in the Ding Navy, except for Zhao Xin, the highest civilian system is the seven-grade.

In other words, if Qipin is considered to be a Ding Navy, in addition to Zhao Xin's high-level level, the section level is equivalent to the middle-level and stock level, and it can be regarded as an official.

As long as the Ding Navy develops, in the future, they may not be able to achieve a very high position, and now, everything is over.

It is impossible for Zhao Xin to keep theirs, starting from the gift to Zhang Hongcai, his family is basically the foundation of Ding Haijun, which no longer exists.

No matter how good their abilities are, it is impossible to leave such hidden dangers, not to mention, they are not outstanding.

In Ding Haijun, there was no substitute before, that is, Niu Dali, and then 12 researchers in materials were added, and the foundation of these climbing technologies was irreplaceable in Zhao Xin's view, and others, including Zhou Chongsun Ji, were not irreplaceable.

Killing chickens and monkeys is always the easiest way, and after Zhang Hongcai was gifted, others may be a little dissatisfied, but they will only talk about it in private.

Of course, it is impossible for Zhao Xin, like a missionary, to suppress all opposing voices, so that the entire Ding Navy has only one voice, although it is currently doing this, but on the surface, it is still necessary to pay attention to balance.

When the other party accepts it and the educational reform can be implemented smoothly, it is fine, and there is no need to go online.

Educational reform, that is to lay a solid foundation in the future, in a short time, is unlikely to have an effect, as long as the master does not raise objections at this stage, the remaining opposition voices will be much smaller.

After all, free education, what to teach, few parents will ask, besides, Zhao Xin will not completely block the road of the imperial examination, in Ding Haijun, most of the compulsory education, will choose such teaching materials to teach reform, but if parents strongly request, traditional education can also be carried out.

However, traditional education is not free, and Ding Haijun will not take the initiative to open it, some traditional old masters, can open classes here to carry out this education, some parents, can also from the perspective of hobbies, let children learn.

Education is expensive, even if it is a large-scale education run by Ding Haijun, intensive papermaking and printing, the cost of cultivating a student is still quite high, if it is replaced by a common private school in the Northern Song Dynasty, under the premise of individual role, the cost is even higher.

But no matter how high it is, there is also a limit, Ding Haijun's education reform did not close the private school, anyone can come to set it up, and only the founder will be assessed, not to ban it, but to avoid the risk of liars.

The existence of private schools is for the examination of the imperial examination, if you don't even have the most basic strength, how can you teach, at the very least, it should be the fame of Xiucai, as for enlightenment, it doesn't have to, it can be carried out in the first three grades of primary school.

Even no matter how stubborn the master is, he has to admit that in terms of enlightenment, Ding Haijun's education reform has been ahead of all private schools.

Regardless of those who are gifted, from the beginning of school, to mastering Chinese characters, being able to read and write, it will take two or three years, or at most seven or eight years, and some stupid people may not be able to master much after ten years.

However, under Ding Haijun's so-called pinyin, he only needs to master twenty or thirty different characters to interpret all the characters, which greatly reduces their workload for children whose intelligence is not very sound.

After slowly becoming proficient and deepening the memory, at most 1 year, you can master more than 300 commonly used Chinese characters, 2 years, you can read through most of the books, 3 years, enlightenment has ended, basically mastering the choice of words and sentences, to a certain extent, than enlightenment, much higher.

The ability to select excellent students from here and enter the private school is very high in all aspects, and it also saves a lot of time for the lecturer.

In the Northern Song Dynasty, the average rural private school was about 1 per month, and the cost of food and books, pen and ink may not exceed 3 per month.

Ding Haijun's private school, on the one hand, is few, plus the requirements are higher, the tuition fee of the private school is basically about 10 per month, and a higher one, it can even reach 30.

It is also a loss for Zhang Hongcai to leave, otherwise whether it is Zhang Hongcai's identity or the achievements of education, if Hongxing Academy is changed to a traditional private school, 50 times a month will not be a problem.

Whether it is 10 guan, or 30 guan, or 50 guan, this is a number that ordinary Northern Song Dynasty peasants can't look up to at all, and even where some landlords are, it's not very easy.

A small landlord with more than 1,000 acres, based on the grain income alone, how much a year, according to 4 stones per mu, the total income is only 2,800 yuan, which is the result of all the sales, 50 yuan a month, 600 yuan a year, and he does not have only one son.

This is an exception in Ding Haijun, at present, the salary level is quite high generally in Ding Haijun, work for more than 3 months, complete the most basic level assessment, after passing, the average monthly salary is 35 guan, a little higher, can reach close to 100 guan.

Such people, of course, can't go to the top private school, but 10 times is still okay, 50 times, middle and senior managers, 300 times a month is no problem, these people are potential consumers.

As long as there is a strong request, it is possible to go to a private school, but Ding Haijun will not endlessly cultivate sour Confucianism, and the private school must go through certain assessments, for example, there are a total of 4 sets of examination papers for the imperial examinations in other places that year, and if each set does not reach certain scores, you can't stay in the private school.

To put it bluntly, this is also a road left by Zhao Xin for private schools, private schools can be run, although Ding Haijun is taking the path of education reform, it does not mean that he will not participate in the imperial examination in the future.

The border military states can also participate in the imperial examination, and there are certain places, these places are equivalent to escorting, maybe about 10 every 3 years, you can enter the Guozijian, if you want to really take the examination and jinshi, you need to go elsewhere to take the exam.

Ding Haijun now, all aspects of the treatment are very good, ordinary people also have the leisure to devote themselves to education, enlightened education, save a lot of time, and then select some not very suitable for Ding Haijun's road, but they can still make a difference in the imperial examination, after systematic study and training, let them go out for assessment.

No matter how you say it, this can be regarded as a kind of cultivation of strength, as for whether these people are crooked, whether their butts are not sitting on Ding Haijun's side, Zhao Xin doesn't care at all.

Even if these people grow up and win the top prize, it will be at least 10 years later, with the current status quo of the Ding Navy, after winning the Ryukyus, they will continue to develop unstoppably, and gradually climb in science and technology and heavy industry, and they will not be able to achieve an overwhelming advantage, so Zhao Xin is really in vain.

Under the forced intervention of Zhao Xin, the reform was completed, although Zhang Hongcai was sent away, so that Zhao Xin was a little helpless, but because of this incident, the acceleration of the entire education reform was promoted, there were no hardcore opponents, and others did not become a climate, and the schools that reformed themselves doubled after a few days, and basically completed the restructuring of most of the schools.

In Zhao Xin's view, a major event that might cause huge contradictions and affect the stability of the entire Dinghai Navy was solved so easily, and the seeds of education began to be planted.

Even if it was the simplest at the beginning, and the scope of the design was not large, the final influence was written into the history books of later generations.

10 years is not a very long time for a force, and even for a teenager's life, it is also not very long, but it is a reasonable education, and in the end, it will affect the entire era, and in the next 20, 30, or even 50 years, it will shine in China.

There is no doubt that ninety percent of the influential scientists in later generations were born in Ding Haijun, and the basis of everything is the education reform promoted by Zhao Xin.

But what is Zhao Xin, who has completed all this, doing now?

Education is the future, it is the foundation of Ding Haijun, but not now, after dealing with this matter, Zhao Xin devoted himself to scientific research again.

At present, even if it takes a lot of hard work, the scientific research strength of the entire Ding Navy is not very strong, the level of knowledge is not good, and the vision is not good.

Zhao Xin not only has more solid knowledge, but also has the bonus of the card system, whether it is ancient chemistry or the synthesis of the card system itself, which is quite good for the bonus of research.

After electrolytic aluminum reached a certain level and the initial completion of aluminum ingots and aluminum alloys, Zhao Xin knew that before the large-scale emergence of electricity, the popularization of aluminum was just a flash in the pan, and it was natural to turn the target to polymer organic compounds.

Polymer organic compounds, their basis, basically, are from oil cracking, which is very dangerous, especially in the previous environment of the Ding Navy.

Petroleum is combustible, and it is a thing that is cracked out and has a stronger combustion performance, such as gasoline, which is the fuel in the daily motor vehicles of later generations, and its volatile nature makes it very easy to ignite, as long as it is close to the fire source.

If at night, even a candle or a kerosene lamp, as long as the gasoline volatilizes, it is very easy to ignite, and even a certain mixing ratio will produce an explosion.

Not only is this easy to do at night, but in a small room, under the premise of a high mixing ratio, it is also easy to explode, iron collision, or other collisions caused by sparks, which will cause problems in oil cracking.

In the past, oil cracking was often carried out outdoors, and there was a large space indoors, but even in the daytime, under the premise of glass windows, when the room was large to a certain extent, the visibility was low, which was not good for experiments.

The outdoor space is large and easy to disperse, and even if there is a certain amount of Mars, there will be no danger.

If it is not dangerous, it is not dangerous, but for the laboratory, the environment in the field is not well controlled, and it is prone to many accidents.

There are only 3 talents that are easy to cultivate, and none of them can make losses, and Zhao Xin had no way before but to choose such a safe method.

But now, with the advent of electric lights, this problem has been solved, it doesn't matter if the room is large, just make a little more light bulbs, and in the same way, through various arrangements, you can minimize the accident, and you can carry out some similar experiments.

Previously, after a long period of research, the cracking and separation of petroleum was mainly completed, mainly gasoline, diesel, and asphalt.

This kind of cracking is only the most basic, and it is the simplest of petrochemicals by heating to a certain extent and carrying out simple diversion.

What Zhao Xin needs is not this, but deeper materials, for example, various common polymer materials in later generations.

These can be used in experiments, after the previous distillation and condensation, the main products produced are not collectible, and it is difficult to do these in the field environment.

Indoors, through some glass jars, or even specialized plumbing rooms, the collection is carried out.

These days, Zhao Xin's harvest is not small, oil is a polymer of polymers, which contains a lot of things, different types of oil, their molecular structure is not the same, Zhao Xin through cracking, by adding some materials, and then through other methods, even if it is a gas, even if it is a mixture of gas, it can also be collected through the card system.

In these days, a lot of basic compounds have been collected, but they have to be separated, and for this level of the Northern Song Dynasty, the requirements are slightly higher, and he must choose other methods to intervene in the organic matter.

There are many types of organic matter, and there are many different systems, what Zhao Xin values the most is still commonly used in later generations, for example, plastics, such as synthetic ammonia, these are the key points, industrial production is not to think about, then the laboratory, but it can be considered.
