In Xinyuan, the turmoil outside was eliminated by the escort team, Chunya, and Mei's people, and the interference with Zhang Chun and Lizhi was very small.

Zhang Chuncai was able to concentrate on revising "Rural Problems", which introduced the distribution of rural land, rural environment and health, the relationship between the structure of agricultural industry and the environment, the composition of peasants' income, the current situation of peasants' means of production, the analysis of the economic structure that can be implemented in rural areas, the relationship between villagers' autonomy and government co-ordination, the feasibility of collective economy, how to prevent officials, administration, finance and auditing, democratic supervision mechanism, rural cultural development and protection, and mass prevention and treatment of rural medical care.

In fact, what Zhang Chun has implemented in recent years is a collective economic model. It's just in Zhang Chun's personal name. If the rural areas want to develop, educate, and expand the army, it will certainly not work without money, and what Zhang Chun wants to do is to theorize and legitimize this model. This may be controversial in later generations. But now, it is very good that the peasants can have something to eat, not to mention that Zhang Chun has given a balancing mechanism between them and the officials.

Lizhi mainly wrote the first few parts, she raised some questions, Zhang Chun answered them based on some experience of later generations, and finally completed the book.

The manuscript was sent to Xu Zhenpeng for verification, and the school's newly purchased printing press arrived. Typesetting and printing.

Zhang Chun's first lecture was not "Rural Problems", but social investigation and statistical analysis, and he believed that the rural problems in each place are different, and there are obvious differences between Nanjie Village and Baimin Lane and Yanmen. Therefore, it is necessary to go through a serious sociological investigation and statistical analysis to find the common points and differences in the discussion of problems, so as to accurately find a solution. Society is evolving. At present, the problems of the peasants are mainly the problems of land, the gap between the rich and the poor, the problems of land annexation, and the problems of exploitation. However, in such a blank space as Yanmen, what kind of economic model will be formed and what kind of problems will arise cannot be generalized. Without investigation, there is no voice. So even the book "Rural Problems" will become incorrect as society evolves. The task of the crash course for cadres is to conduct investigation and study.

Books were left in the library and quickly borrowed.

When Zhang Chun and Lizhi were lecturing, not only did they listen to the crash course, but other majors also slowly attracted them.

Both Zhang Chun and Lizhi encouraged the students to study the problems in the book in detail.

Because the teaching and research team of the primary school is still there, this book is also given to the teaching and research group, so that the teaching and research group can use it appropriately when compiling the primary school textbook.

Unexpectedly, the first professional paper on "Rural Issues" was "Land Distribution in History" written by Guo Hua, a spicy girl, who actually went through the land issues of various dynasties in history, pointing out that the land issue is the foundation of China and the root cause of prosperity and demise. Although Dr. Sun Yat-sen put forward the idea of equal land rights, it was obviously too simplistic. The discussion of collective ownership in The Rural Problem is probably the most effective solution to the land problem.

Zhang Chun saw the manuscript and hurriedly came to the girl, saying that the article was very well written, but any kind of idea must be proved correct through practice, so the article should not be spread outside, just publish it in the primary school hall and the agricultural school. Because this is designed for the goose gate, it will cause unnecessary trouble in other places, and maybe kill people.

Guo Hua put forward a request, after the compilation of the primary school textbook, let her go to the cadre crash course to study, she wanted to see if she could implement it.

Zhang Chun could only agree.

Cliff Mountain, located in the middle of Shinu Mountain and Yunling, is 30 miles away from Yunling Village and 20 miles away from Xiaofengling.

There is a fault zone here, named after a cliff about 30 meters high. Below the cliff is a small basin with three roads in and out, one leading to Yunling Village and one leading to Xiaofengling. One leads to Baiping Dam. Baipingba is one of the few dirt mountains in Shinu Mountain. In the past, it was the entrenchment of a group of bandits, but now the bandit leader ran away with his henchmen, and Baipingba slowly gathered more than 40 families because there was some land to cultivate, and sent people to Xiaofengling to surrender and ask for help. Zhang Chun, the representative of Xiaofengling, received the gang, and the cadre crash course sent two students and Xiaofengling's militia to live in Baipingba.

There are no paddy fields in Baipingba, all of which are dry land. But there are mountains full of chestnut trees, so forestry students rushed to where to practice, and in a short time grafted hundreds of acres of chestnuts. was criticized by Zhang Chun for this. It's naturally good to help others do good deeds, Baipingba is full of hillside land, there are landslides everywhere, you cut down a large area of mountain forest, and it will be bad if it rains next year. The core of the whole agronomy of the College of Agriculture is the small environment, and forestry has always been in a weak position compared to agronomy.

Because of the possibility of geological problems, Wang Renbin took students studying geology from Xiaofengling Coal Mine to Baipingba to conduct field investigations and confirmed the existence of landslides. Jokes aside, this landslide body has caused damage every time in later generations, resulting in the relocation of three villages in Baipingba.

Wang Renbin believes that the problem of landslides is mainly in water, and after solving the problem of water, two years later, the chestnut forest will become a forest, and the danger will naturally be reduced.

This incident was thrown back to the group of students who caused trouble, and they made up for their own troubles.

But when Wang Renbin came back, he just wanted to take the students to know the fault by the way, but he didn't expect to bring Zhang Chun a surprise. They found that there was a copper ore belt there, and the samples were returned, which belonged to high-sulfur copper-iron ore, which was of very high grade, and that there was a certain amount of gold and silver in it. This was a surprise for Zhang Chun, as he had never heard of copper and iron ore here. But then came the news that, like the coal mines, the grade is high but the scale is small.

Because the location of the copper mine is not far from the Ordnance Research Bureau converted from the Machinery Factory, this small copper and iron mine is no less than sending charcoal in the snow for the Ordnance Bureau.

Compared with other minerals, the cement limestone mines in Yanmen don't need to be seen, they are everywhere.

Therefore, Wang Renbin believes that the cement plant does not need to be in a hurry, and the small scale is fine, but the copper and iron ore should be put into production as soon as possible.

Xu Zhenpeng also believes that if it is necessary to make some preparations before the arrival of war, it is more economical to use the copper and iron smelter to purchase some equipment. It would be good for the firearms to set up a production line. The ammunition station should also improve the production line. Because Zhang Chun believes that he should have his own weapon research ideas, Liu Guangli believes that inheriting the gunpowder use method of traditional Chinese firecrackers, the most likely thing to complete is the development of rockets proposed by Zhang Chun, which has many advantages, and the research of ammunition by the Institute of Chemical Engineering has lasted for many years, and the results are good. The Ordnance Bureau focused on the development of rockets and special ammunition, improved sniper rifles, and finalized semi-automatic rifles. This is the most economical and fastest way to build combat power.

Zhang Chun approved this plan, and the current economic capacity cannot go long. It's better to break through a little. This copper and iron mine can be mined in the open pit, and the explosives of the chemical industry are already very advanced, so short-term mining is not a problem.

Wang Renbin came back to design the smelting equipment, the smelter already has a certain foundation, and the flotation equipment and magnetic separation equipment are not backward in technology except for small points.

However, for the machine factory, the previous ten-ton hydraulic press was too small. Seiko has been exploring hydraulic presses for several years. Now it is necessary to improve a more advanced forging equipment of at least 50 tons, and make technical preparations for the manufacture of more hydraulic presses. Of course, the condition is also that the production line is completed, because often a small part cannot be made, and the whole plan has to be delayed. These machines are not firearms, the mechanisms are very complex.

After Zhang Chun gave up the construction of a large factory. The production workshop in Luyuanshan is developing in the direction of small and delicate, and the production line is also being lengthened, because the process chain is lengthened. Smelting, refining, and foundries are also constantly improving.

Because the cliff copper and iron mine no longer pursues high yield, small smelting equipment is quickly installed in place, due to the consistent environmental protection awareness of the agricultural college and the madness of the chemical group. They want to eat all the by-products and wipe them out. So in addition to sulfuric acid, copper and iron, they also got gold and silver. But because the value of gold and silver is high enough. So to talk about the flowers in terms of wealth. This small mine is actually a gold and silver mine.

And just like that, they're trying to get something out of the tailings.

Their extremely demanding requirements have actually affected the factory area as well. In the factory area, all processed scraps are recycled, and the equipment is scrubbed cleanly because it is rare to build. Grease and sewage are pooled for purification and recycling.

More than 30 new students called the people at the Institute of Chemical Engineering and the Institute of Environment crazy. Because most of the people in these two institutes are girls, the others put up with it. With them around, you have to look around for coughs. However, because of the existence of these two groups, so many factories have been built, and they are still full of green trees. Even the furnace in the smelter is getting more and more strange and bigger, but there is only a faint water vapor......

The smelter near Zilin has three large furnaces, as well as some small furnaces, after all, they want a lot of small things, such as activated carbon and various glass products. These small factories are hidden in the greenery, and if you don't pay attention, you really don't know what you're doing at this time.

And if you don't approach the Xiaofeng Coal Mine, you don't know that there are still a few buildings there, and there are people digging coal in caves. Cliff copper and iron mine, then there were no trees. They are also preparing to plant trees in the spring.
