When it comes to port construction, Li Zhongxin thinks of another thing.

At this time, Zhongxin Company should take the initiative to find the place where he wants to build a port in the next few years, and form a large port and warehousing group with the local government.

A port is a transportation hub with water and land combined transport equipment and conditions for ships to enter and exit and berth safely.

It is the assembly point and hub of water and land transportation, the distribution center of industrial and agricultural products and foreign trade import and export materials, and the place where ships berth, load and unload goods, get on and off passengers, and replenish supplies.

The port is also a sign of the strength of the country's marine transportation industry.

But what! The construction and operation of the port has a large investment, a long construction period, and is competitive, and at this time, it is an industry that is not very optimistic.

The port industry and shipbuilding industry are not favored by the Chinese at this time, because they feel that there are already many port countries and do not need so many large ports.

Many people feel that there are enough ships now, and there is no need to produce too many ships, even if they are produced, no one will buy them.

At this time, the shipyards were all state-run, and the purchasers of ships were also state-owned.

It is precisely because of this reason that China's shipyard industry is struggling, and many large shipyards have begun to suffer large losses, and they cannot pay wages at this time.

Li Zhongxin felt that in the next few years, he would invest in the construction of several large ports in the country, and also build a large-scale warehousing company in the port, so that in the future, Zhongxin Company would not be too constrained in this regard.

Foreign wine technology is not available in China, and China can only make some very simple wines at this time.

If the technology of making red wine can be promoted in the series of books launched by Zhongxin, then the time for making red wine in China can be at least ten or eight years in advance.

There are many advanced technologies abroad, and China only simply introduced machinery and equipment from developed countries when it was in China, and it is precisely for this reason that China's independent creation ability is very weak.

He felt that as long as Zhongxin Company could promote these things on a large scale, the time for China to become rich and powerful at an early date would be shortened, and China would become a world power as soon as possible.

In the 80s, no one recognized these things, let alone done them. Li Zhongxin felt that since he was reborn into this era, he had to do something for this era.

He knows that it is okay for him to integrate the series, or to get advanced technology, but if he comes up with technology or other aspects that surpass this era, there will be big variables.

The problem of the publishing house has been solved, and the books can be published, so it is necessary to make some practical and good books.

In fact, at this time, what Li Zhongxin wanted to do most was a TV program, and set up a TV station that belonged to Zhongxin's company and the government.

However, at this time, let alone a TV station, it is a publishing house, and without Wang Bo finding contacts in the province, and without the current status of the faithful company, it will not be able to do it.

The road has to be taken step by step, and he can't eat a fat man in one bite, so he must fight steadily and slowly form a big plan that he wants to do.

Li Zhong has a gap in confidence, and after the establishment of this publishing house, on the basis of comics, technology and various craft books, he will also publish a series of books called I Love Invention.

This series of books that I love invention is written from the small inventions and creations of Chinese people.

To use the simplest analogy.

The carpenter's grandfather was Lu Ban, who invented the saw because he discovered something in the shape of a zigzag on a weed.

In modern times, saws have continued to evolve and improve, starting with the saws pulled by two people in the past, to the simplest hand saws now, which can cut through steel.

After the introduction of the chainsaw, the electric saw was introduced.

The country is developing rapidly, advanced science and technology are constantly advancing, most things used to be done with wood, with the continuous progress of the country, some advanced tools such as lathes began to appear.

The emergence of machine tools and other tools formed an epoch-making change, and the second industrial revolution began, and the previous wooden objects were gradually replaced by steel products.

In the early years, saws were produced that could only cut wood, and if they were used to saw iron, it would have been impossible.

Through the change of times, electric saws and saws capable of sawing steel appeared.

After the introduction of the saw, the topic changed and the saw blade was directly introduced.

The material composition of the saw blade is mainly carbon steel and alloy steel.

Carbon steel contains iron (Fe), carbon (C), silicon (Si), manganese (Mn), sulfur (S), phosphorus (P) and other elements, of which carbon is the most important element that determines the performance of steel.

As the carbon content increases, the strength and hardness of the steel decrease, but the carbon content increases too much, and the strength decreases. Silicon and manganese are brought in as deoxidizers in steelmaking, and are called "persistent elements......

Silicon can improve the hardness and strength of steel, but reduce the toughness of steel, manganese will increase the hardness of copper, increase the particle structure, and easy to crack during heat treatment. Sulfur and phosphorus are brought in from the raw materials of mountain steelmaking and are called "impurity elements". The presence of impurity elements will make the steel change, so it should be strictly controlled.

Alloy steel is to add an appropriate amount of alloying elements in the class, these alloying elements are: chromium (Cr), nickel (Ni), tungsten (), vanadium (V), drill (Co), molybdenum (Mo), etc.

Ming can increase the hardness and wear resistance of steel, nickel mainly increases the toughness and elasticity of steel, but reduces the hardness; Tungsten can increase the hardness of steel, but reduce the toughness of steel; Vanadium can increase the strength, hardness, elasticity and toughness of the class, and drilling can improve the toughness and wear resistance of steel; Molybdenum increases its hardness without reducing its toughness.

The first series of books I love to invent starts with Lu Ban's invention of the saw, and leads to the importance of invention step by step, telling about the most simple invention.

Start with a very low-end layout and guide people's desire to look at it step by step.

Then at the end of the book, an advertisement is placed in other books published by Faithfulness Press, and those who like to invent are welcome to submit, and once accepted, Faithfulness Press will give a first prize of 1,000 yuan.

Li Zhong is very clear in his confidence that China had four great inventions in ancient times, and it is precisely because of China's four great inventions that the process of social development has been greatly promoted.

At this time, what China needs most is people who are engaged in invention and creation, and what it needs most is people who can create new things.
