In the twentieth year of Chongzhen, the Central Academy and even the entire Yingtian School City began to enter the era of new practice. After about four years of cultural remedial classes or handicraft ability remedial classes, the teenagers who originally had good talents when they were selected have caught up with the seniors of the year in a short period of time. According to Xiao Xuan's view, after a generation and two and a half batches of reproduction, the first dozens of children finally "peach and plum sky" through the maximum expansion and even new teaching methods first developed into a full number of students in seven years, and the new normal students of the scale of a school have gradually made hundreds of thousands of talents in the world gradually become talents in the real sense.

From laboratories to various experimental workshops and even mass production factories are also becoming more and more complete, according to Xiao Xuan's original idea: this should be the time when many bottlenecks in the past have been broken through, and most historical overheads often at least begin to be practical in steam engines when they have been in power for about 20 years.

Xiao Xuan recalled some changes and practices in the past, and it can be said that he had made much more radical changes in order to transform the culture, order, and system of the entire society than most of the protagonists in ancient history, and he also invested in rewards that had never been seen in many dimensions.

However, in the past 20 years of Chongzhen, there have not been many revolutionary breakthroughs in "replacing the old with the new" in the various reports obtained, except for the increasing number of blacksmiths, the increasing scale of the entire number of skilled workers, the increasing number of clocks, telescopes, four-wheeled carriages, and even the arsenal of arrows, shotguns, and steel artillery, and the increasing number of iron-hulled ships.

The steam engine is still not practical in the economic field because of the sharp rise in coal prices. What is a "condenser" and how the piston should be set still traps a large number of people. In the field of iron and steel smelting, the lack of refractory materials and even the lack of understanding of the properties of iron ore have caused hundreds of casualties.

In the field of mathematics, the progress of the past seven or eight years has gradually reminded Xiao Xuan of some bits and pieces of college homework to a very large extent.

Progress in the field of electricity has been rapid, at least within the confines of the laboratory. Electrocution, wired communications, and hydroelectric generators all have shadows. Battery technology is still a long way off. As for the rubber processing and photographic technology that appeared in the era of the first industrial revolution in the early 19th century, there is not even a shadow of it. The technology of the whole society is constantly improving, but there is still no breakthrough in the sense of a major revolution.

Of course, unprecedented progress in education and even investment, and a series of institutional and commercial policy changes gradually blossomed in Chongzhen's 20 years. The cultural industry, the construction industry, the metalworking industry, and the machinery industry with the core of literature and newspapers as the core flourished like never before.

It's just that these have not relieved Xiao Xuan's hidden worries. In some "experimental towns" near Yingtian and even the "experimental villages" in the outer city of the heroes, there have been rough inferences. If it is possible to achieve a society in which both men and women receive "ten years of compulsory education", receive complete technical training and cultural knowledge, and even have at least two years of internship, and to a large extent, the supply of agriculture is also abundant, the urbanization rate can be achieved at least about half, and the proportion of non-farm employment in the labor force can reach two-thirds. Even so, the per capita economic level of the entire economic system, which can convert the price of 4,000 catties of finished grain, can be regarded as sky-high. Although ten times the per capita economic level of the old era will change the face of the whole society, it also seems that it will become a bottleneck to some extent? A technology much inferior to that of Victorian England, at best at the level of mid-to-early eighteenth-century Europe, and only because of the development of education and skilled workers and even the popularization of urbanization that it reached the per capita economic level of the mid-to-late nineteenth century?

Of course, even so, if you put it in about thirty or forty years, it can be called a sea change. In the 39 years of reform and opening up in history, from 1978 to 2017, excluding price growth, the actual economic scale is about 34 times that of the original, and the per capita economy is about 25 times that of the original. But if we only count the real per capita economic growth in the past 30 years to 2008, it is probably only a dozen times. In order to make the whole country reach this level, according to Xiao Xuan's estimate, I am afraid that it will take another generation or so, starting from the end of the expedition and the second war of rebellion, and it will take a full thirty years to fully perfect.

Now where is he stuck in many technologies, Xiao Xuan is not completely out of the picture. In fact, I knew very early on that because of my knowledge structure, I seriously failed the chemistry examination in the field of chemistry because of the junior high school entrance examination, and this was my own shortcoming in high school, so at this time, the accumulation of the entire Ming Dynasty in the field of chemical engineering was almost no stronger than the blank.

Therefore, in the official publication "Central Monthly", on the New Year of the twenty-first year of Chongzhen, Xiao Xuan prepared two articles that had a great impact later: the first is: "Where are we missing? ”。 In the article, Xiao Xuan pointed out that there are serious problems in our language structure and even the entire way of thinking, lacking deductive thinking and inductive thinking, and in daily life, we have too many taboos and too many analogies. Some old Guangnan opera troupes, because the word "umbrella" has the same sound as "scatter", they have to be called "rain cover", "rain shield", "rain cover", and "rain block". For example, the people on the boat said words such as "turn over and rest", so they called the "sail" "peng" and the "chopsticks" "chopsticks". In the folk, it is usually considered that words related to sexual acts and ** officials are a kind of blasphemy, which is harmful to say, and educated people are ashamed to speak up. When you have to talk about ** official, you should replace it with "lower part", "pubic part", etc. When it comes to sex, it is also necessary to use simple words such as "errand", "sexual affairs", "sharing bed", "married life", etc., and even "" is also taboo. In daily life, people change the name to "stool", "big solution", "relieve hands", "go to the toilet", and so on, as well as women's menstruation, people don't like to say it directly. How can such a civilization, which does not seek truth from facts and dare to speak out, create a tradition of seeking truth from facts, daring to face it head-on, and pursuing the truth? In our history books, there have been nearly 30 records of comets, but no one has been able to find that the records of this comet have a specific cycle. No one has been able to summarize the rules except for using it as a political metaphor...
