When Zhu Jingyuan first spoke, the logic he subconsciously wanted to talk about was not actually a matter of productivity and distribution.

Instead, use high-tech products and good value-added products to go to Daming's takeaway at a high price and obtain high profits.

But Zhu Jingyuan immediately realized that the size of the Ming in this world was too large.

Half of the world's population is now in total, and that number could be even higher in 20 years' time.

Simply relying on poor technology scissors and luxury IQ taxes to pump the blood of those hundreds of millions of Taixi people cannot make all the Ming people developed, only some people can be developed.

Of course, blood is still drawn, and the amount of blood drawn is not important to one's own gains, but to Tessie's losses.

Zhu Jingyuan and Chu Yuqiang have been doing this.

Now that the Taixi people can't make elastic silk and rayon, Zhu Jingyuan supports Chu Yuqiang to sell a hundred times the profit.

It's just pantyhose as a daily necessities, and it has nothing to do with military and industrial technology.

At the same time, allowing a small number of vassal states to export special resources, such as making the big food countries dependent on oil sales and petrochemicals, to maintain a high standard of living for some of them, could breed separatism.

Except for Zhu Jingyuan, the prince's big food country, other places are really not suitable for this.

As a result, Zhu Jingyuan had to raise his realm and put the solution to the problem on productivity and distribution.

This is the principle that the current Ming Dynasty applies, and the future Ming Dynasty will also apply, even if the Ming Dynasty unifies the world, it will still apply.

Zhu Jingyuan chatted with Hao Zhongyi and other craftsmen and workers for a while, and finally encouraged them to work hard, earn more money, and live a better life, and then let them go back to work.

I continued to have a meeting with Lin Zexu, Niu Jian and other officials to discuss the direction of the exam for follow-up preparation:

"I would like to remind you of the plan to allow certain ethnic groups and mixed-race people to pass the examination and obtain citizenship in the Mozhou region of the Great Food Country.

"First of all, pay attention to the fact that this kind of assessment is not a test of ability and knowledge level, if the elite of foreign races is purely allowed to join, it is not a good thing for our Great Food Country and even the Ming Dynasty."

Zhu Jingyuan paused here for a moment, Lin Zexu, Niu Jian and other officials were stunned for a moment, and then after a short period of consideration, they all nodded with serious expressions.

At the same time, I once again sighed in my heart about Zhu Jingyuan's sensitivity and directness.

The assessment of ability and knowledge is equivalent to putting foreign elites in and competing for jobs with Daming's own elites and even ordinary people.

Not to mention that the ordinary people of Daming are unhappy, and the elite groups of Daming are also unhappy.

Zhu Jingyuan is actually thinking more long-term, and he is not just concerned about the interests of the Ming people.

Zhu Jingyuan was thinking about the future ethnic policy of the Ming Dynasty, which was the divergent thinking that began to diverge when chatting with Hao Zhongyi.

The current status of the Ming Dynasty may be similar to that of the United States in World War II and the United Kingdom before World War I in Zhu Jingyuan's previous life.

But this is just a comparison of status, and the situation of Daming is completely different from them.

Compared with the United States, Daming is not a country of immigration, Daming has its own basic ethnic group, and it is very strong.

The United States can be relatively open to absorb all Tessie whites, and after the integration of Tessie whites, they are the main body of the United States.

The Ming Dynasty must put the interests of his natural subject group above other outsiders, and no one can do the opposite.

Compared with the United Kingdom, the basic plate of the Ming Dynasty is larger, enough to suppress and control the feudal state, and the traditional culture of the Ming Dynasty is also strong enough.

Britain had to take into account the situation of the colonies, formulate management plans based on the culture of the colonies, and must accommodate the culture of the colonies.

The purpose of British colonization was to obtain markets and raw materials, which did not fit the original meaning of "colonization".

The "colonial" action of the Ming Dynasty is more in line with the original intention of "colonization".

The largest market of the Ming Dynasty is the mainland, and some of the feudal states are resource supply bases, but most of them are "colonial land".

The Ming Dynasty didn't need to, and couldn't pay too much attention to, the natives of the colonies.

In order to accommodate or even satisfy the interests of the people of the domain, we should not ignore or even go against the interests of our own basic system.

The result of doing so is to cut off the roots of your own dynasty.

Moreover, the main ethnic group of the Ming Dynasty also has a sufficient scale, and after the reform, there are 420 million pure-blooded Ming people.

Relative to the overall population of more than 700 million people, it still accounts for 60%.

What's more, these sixty percent of the Ming people are also directly related to 140 million mixed-race children.

In everyday life, it is difficult for them to distinguish each other.

There are only 150 million pure natives left.

Therefore, the Ming Dynasty could not learn from the strategies of Britain, France, and the United States in colonial and ethnic management in history.

It can't be like the United States opened up to absorb the elites of Tessie, so that the elites of all ethnic groups around Shenzhou can directly join the Ming Dynasty.

The main ethnic group of the Ming Dynasty will not allow the decision-makers to do so, which is to the detriment of the interests of the main ethnic group of the Ming Dynasty.

The point is that after absorbing the elites of the other party's ethnic groups, the other party's ethnic groups themselves still exist.

What the Ming wants to absorb is the other party's ethnic group, not some special individuals.

The object that Da Ming can refer to is the historical Lucian Empire.

A negative teaching material that needs to be taken as a warning, a general teacher who repeatedly cheats corpses.

The problems of the Lucia Empire in ethnic affairs actually existed and manifested within the Ming Dynasty.

The secondary races, which were supposed to be assimilated and absorbed, did not really fully integrate into the main group.

The western and southern Slavic tribes each established their own ethnic cognition, rather than merging into one.

The best time for ethnic integration was before the advent of modern nationalism, in the classical dynastic era.

The process of industrialization, the process of continuous civilization and enlightenment, is the process of constructing the cognition of modern ethnic groups.

The situation in Daming has actually reached a critical point.

If the current system of communal management continues, the remaining natives may become similar to the Slavs.

Koreans, He, Luzon, Siamese, and Burmese all belong to the Celestial Empire civilization, but they are not Ming people.

Zhu Jingyuan wanted them to be equated with Shandong, Suzhou, and Zhejiang, and become a subset of the Ming people, rather than an intersection.

If you pass this tipping point and still want to take full control of the land they live in, you can only make them disappear completely.

Zhu Jingyuan looked at his two staff members with a rather complicated feeling, and also had high hopes for them:

"The direction we want to look at is the way of thinking of the other party, or the cultural fit.

"Look at the way the other party lives and does things, is it like an ordinary person with a Ming Dynasty.

"In particular, these assessments should avoid factors that can influence the individual's ability and level of knowledge.

"Therefore, the questions in the exam should be as life-like and daily as possible, and not have the difficulty of knowledge.

"Only examine the other party's expression ability, expression, and whether the use of Daming Yayan is proficient."

Lin Zexu, Niu Jian and the officials nodded again when they heard this.

In this way, most of the recruits are ordinary workers, which will not affect the interests of the Ming elite.

It will not affect the interests of ordinary people, because foreigners who pass the assessment can also get the same remuneration as Ming workers.

This would deprive these foreigners of the advantage of relative cheapness.

These foreigners and the Ming people originally lived together, not cheap labor specially brought in from the outside.

There is no difficulty in the exam, as long as you learn the Daming Yayan and get the certificate, you can join the Daming group.

The direct standard of remuneration and benefits will drive these ordinary people to use all means to learn the Ming language.

It can also add some jobs and increase some employment opportunities, so that ordinary Ming people can also become teachers of Ming language.

Koreans and Hezu people, who can basically speak Da Ming, should soon disappear as a whole.

Other images that are not significantly different from those of the Ming people should also be able to dissolve quickly.

As for those with obvious differences, then use intermarriage to wash it constantly, not everyone is qualified to become a Ming person.

Zhu Jingyuan planned the direction, as for the specific effect, it can only be estimated at present, and I think it should be feasible.

Mengxian Industrial Zone, Mozhou Region, Dashi Country, can be regarded as a test field for this program and system.

If it doesn't work well, or if there is a big problem, you have to stop or adjust again.

If the effect is good, or the effect is good after adjustment, it can be promoted in other feudal states and even the Ming Dynasty itself.

Zhu Jingyuan is a decision-maker, unless only he can do it, he will rarely directly participate in specific work.

After arranging the direction and requirements, the details and specific implementation were left to Lin Zexu and other officials to toss.

Zhu Jingyuan began to plan other work, designing air conditioners.

Although I came to Mengxian County to escape the summer, I can't forget my work.

A more comfortable environment allows Zhu Jingyuan to work with more peace of mind.

Air conditioning is a very important piece of equipment, and its purpose is not only to make people's lives more comfortable.

More importantly, industrial air conditioners can directly improve production efficiency.

I can go to Mozhou for a vacation, but my own people and workers can't all come, otherwise who will exploit the oil field?

Military air conditioning, improve the mechanical efficiency on the battleship, improve the efficiency of the soldiers, and then improve the combat effectiveness,

The point is that if you want to use a battleship as a yacht, then the battleship must also have air conditioning......

The principle of air conditioning is actually quite simple.

It is to use the three-state change of matter to continuously absorb heat from the room to the outside of the room, and continuously circulate and transport heat.

When designing an air conditioner, you can make a refrigerator by the way.

An air conditioner and a refrigerator actually work on the same principle, a refrigerator is an air conditioner that treats the interior space as a room.

The principle of air conditioning is very simple, so in fact, the relevant attempts have been studied for a long time.

But the key to making air conditioners and refrigerators is "refrigerant", or "refrigerant".

This carrier and medium, which is responsible for repeated vaporization and liquefaction cycles, and continuously transports heat.

Humans have experimented with refrigerants in history, using alcohol, gasoline, carbon dioxide, sulphur dioxide, and even sulphuric acid.

Most of these guys have strong side effects, think about the effect of sulfuric acid as a refrigerant......

Therefore, air conditioners have not been widely used for a long time.

It was not until the twenties of the twentieth century that the "chlorofluorocarbons" known as "freons" were born.

The refrigeration effect of chlorofluorocarbons is very good, the key is that the chemical properties are very stable, they are inherently non-flammable and non-toxic.

Once considered the perfect refrigeration material, these compounds quickly led to the rapid adoption of air conditioners and refrigerators.

It wasn't until decades later that scientists discovered that chlorofluorocarbons, while not toxic, could deplete the ozone layer.

Driven by environmental trends, people are starting to look for more suitable refrigerants.

Non-toxic and harmless, good refrigeration effect, and refrigerant that does not harm the environment, Zhu Jingyuan doesn't know what other materials can meet.

In addition to groundwater......

Groundwater can be used as a refrigerant, but the use scenarios are severely limited.

The temperature difference between winter and summer is very small, and it feels warm in winter and cool in summer.

As long as the groundwater is pumped out, passed into the heat sink, and the air circulation is driven by a blower, the space can be cooled.

The key is what to do with the water after absorbing the heat.

The best way, of course, is where you came from and where you go back.

But the problem is that groundwater can be pumped out continuously, but it can't be pumped back back at the same rate.

Balancing pumping and irrigation requires an unusually large seepage system, and the construction cost is of course unacceptably high.

The next best solution is to purify the water used in the air conditioner and then use it as domestic water.

But this is equivalent to pumping groundwater openly, and if the whole city pumps groundwater for water air conditioning, the city will settle sooner or later.

Even if a "big dog" like Zhu Jingyuan can spend money openly to get a water circulation air conditioner for his palace, then its effect will be very limited.

There is a constant depth of groundwater temperature, that is, the point at which the water temperature is exactly the same in winter and summer.

It is usually in the range of ten to twenty meters underground.

Groundwater above this depth has a temperature that varies with the surface air temperature.

The temperature will drop in winter and increase in summer.

If you want to use groundwater to regulate the temperature, you must aim for the water temperature to be as low as possible in summer and as high as possible in winter.

Therefore, the source of water for groundwater air conditioning can only be selected at a constant point in summer.

The temperature at the constant point of groundwater temperature is the theoretical limit of regulating the temperature of groundwater air conditioning.

Combined with the heat loss during the heat transfer process and the water flow, the actual regulation capacity is reduced by a few degrees.

However, the water temperature at a constant groundwater temperature is very close to the annual average temperature of the local ground.

Temperatures are usually slightly higher than the local average annual temperature.

On the side of Quicksand City, the average annual temperature is estimated to be around 27 degrees.

If Zhu Jingyuan really did not hesitate to build groundwater air conditioning in the palace of Liusha City, it would be a very ideal state to reduce the room temperature of the palace to less than 30 degrees.

In summer, the air conditioner can only cool down to 30 degrees, what do I want you to do......

Groundwater air conditioning should only be suitable for temperate areas with large annual temperature differences, but the average annual temperature is not too high.

For example, the northern region of the Ming Dynasty, and the northern region of North Yinzhou.

And it can't be used on a ship.

Therefore, if Zhu Jingyuan wants to make air conditioning, he should concentrate on freon directly.
