Under the rule of the People's Army, there are more and more businessmen who want to carry out cross-border glass mirror business, which was mainly the merchants of Guangzhou City, and soon expanded to all businessmen with background and ability under the rule of the People's Army.

The most critical factor is Liang Xin and several other merchants who have opened up trade routes, they have already carried out several glass mirror businesses, especially Liang Xin, the third batch of glass has been traded and sent to the border city.

In the first glass mirror business, Liang Xin only earned 2,200 taels of silver, and in the second batch of glass mirror business, Liang Xin earned more than 7,000 taels of silver.

This glass mirror business doesn't need to go on for too long, it only takes a year, and there is no problem for Liang Xin to double his net worth at all.

The interests are moving, no businessman can look at the glass mirror business indifferently, and more importantly, the People's Army seems to encourage businessmen to do glass mirror business, businessmen only need to open up trade routes to sell glass mirrors to get rich returns, but not all businessmen can open up trade routes.

Even big businessmen like Jiang Ci and Xia Jingshan did not open up trade routes, so they could only borrow Liang Xin's trade routes to do glass mirror business for the time being.

The businessmen thought well, the People's Army did have the intention of encouraging the businessmen to do the glass mirror business, the reason is very simple, Fang Nan wanted to develop industry, factories were established, and the products had to be sold.

For example, in this glass factory, the glass mirrors produced are easily satisfied with the situation under the rule of the People's Army, but how to develop the industry, expand the glass factory and establish a number of glass factories belong to the development of industry, and the glass mirrors that can be produced cannot be sold, and it is useless to expand the glass factory.

Since the People's Army-ruled area can't digest so many glass mirrors, it will be sold to the Daming Ruling Area, and the price of the glass mirrors in the Daming-ruled area has increased dozens of times, but there are more rich people in the Daming Ruled Area, and they can sell ten times more glass mirrors than the People's Army-ruled area, and the glass factory has developed.

When the next war between the People's Army and the Ming Court broke out, Fang Nan was confident that the People's Army would defeat the Ming Army and expand the scope of the People's Army's domination, and there would be no need to worry about the sales of glass mirrors at that time.

Let the merchants sell the glass mirrors to the Ming Dynasty, on the one hand, to develop industry, on the other hand, the People's Army can collect a commercial tax, which is much higher than the commercial tax that only does business in the territory.

In addition, Fang Nan's attention to the glass mirror business is not only for the development of industry, you must know that the role of glass is not only for door and window glass and glass mirrors, but more importantly, for military and navigation telescopes, as well as for modern medicine microscopes.

Low-power telescopes have already been produced, but the output is relatively low, and they are only distributed to officers above the division commander level, and when it comes to mass production, they will be distributed to the company commander level.

The microscope is progressing much slower, and it is not expected until next year that the first working microscope will be produced.

The equality coin has the greatest impact, and the glass mirror also has some influence, but the impact of cement on the people is greater than that of the glass mirror.

At present, all cement plants have started to produce cement, and the People's Army has contracted all the cement produced by cement factories in various places, mainly for the construction of cement roads and water conservancy facilities.

The water conservancy facilities built with cement are characterized by fast and sturdy, and the people who participated in the construction of hydraulic facilities were very puzzled by the cement, and they saw the cement for the first time, and when the cement solidified, they found that the water conservancy facilities built by the cement were much better than the water conservancy facilities they imagined.

If you only have a water conservancy facility built of mud and stone, there may be some small problems when a heavy rainstorm washes down, and when many heavy rainstorms come down, small problems will become big problems.

However, when added as a cement binder, the hydraulic system is much stronger and can last longer.

The cement road paved with cement is basically outside the city, but there are many people who like to see the excitement, walk and step on the cement road outside the city, and the flat cement road is easier to walk.

Clever people can quickly think that the carriage will run on such a flat concrete road without bumps at all, the chance of fragile items being broken is greatly reduced, and the concrete road will not be muddy on rainy days.

Many people wonder when it will be better to lay concrete roads in the city.

Paving cement roads in the city, the local people's military governments do have this plan, but Fang Nan has other plans.

In Fang Nan's view, the city with the city wall obviously cannot meet the future development needs, the future city is dominated by multi-storey buildings, sewers, canals, and the main roads should be more spacious......

Under various requirements, the city must be overhauled, but it is obviously a very troublesome thing to carry out a major renovation of the city, after all, there are a large number of residents in the city.

Therefore, Fang Nan started from the side of Guangzhou City, the Guangzhou City wrapped by the city wall is the old city, and the new city was established outside the old city, and some factories were mainly established at present, and there were also many buildings being built, with the increase of the population of the new city, the various agencies of the People's Military Government will move to the new city successively, and the population of the old city will also be transferred to the new city.

When the population of the old city is almost reduced, the old city can be renovated, or directly demolished and rebuilt, or a small part of the renovation to retain the "ancient" characteristics of the old city.

It is expected that in the future, all cities will change like Guangzhou, and the construction of new cities will occupy some farmland, which needs to be prepared, and the people can also be allowed to work in factories.

The good life of ordinary people has only been two years, and the money they earn from farming is not much, and they have to think about even buying a mirror for days, and they think more about saving the money in case of emergency.

The good life of the common people will continue, and when there is more money left in their hands, the common people will also consume, buy glass mirrors, buy cement to build houses, and buy other things, and then the industry of the People's Army will usher in great development.

It is one thing that the people have more money in their hands, if the B-type steam engine is researched and manufactured, it will be the greatest help to industrial development, and the textile mills can produce cheap cloth in large quantities, and the people's income remains the same, but they can buy more cloth, and the same is true for other goods that can be produced quickly by industry.

This does not include daily necessities such as matches and soap.

Matches and soap may seem like simple goods, but they are much more difficult to manufacture than glass.

For example, soap was a luxury item in the early days, and it was not until 1791 that the French chemist Lu Bulan succeeded in making caustic soda cheaply by electrolyzing salt, and it was not until the end of the 19th century that soap was industrially produced.

The difficulty of making matches is lower than that of soap, and the yellow phosphorus match industry can also study it, but it is not something that can be done in a short time if you want to carry out industrial production.

Fang Nan was not too anxious, things came one by one, and when the literate population increased rapidly, the speed of scientific and technological development would also accelerate.
