Liaoning Prefecture, when the car entered here, the biggest difference between Li Ke and his previous life was that there were more state-owned farms here, supplemented by some private farms.

Private farms are a type that was once given to those family gate valves, allowing them to buy and contract in large quantities, initially with state-owned commercial bank investment, and later allowed some family gate valves to buy land privately.

Of course, private land also needs to be planted in accordance with Datang's official regulations.

To this day, Li Ke doesn't know how many people still keep it, but it seems that the current number is not too small.

Because of the vast land area of Datang and the very early time of urbanization, there are not too many people left in the countryside, which has the ability to large-scale mechanized planting.

In recent years, the popularization of intelligent data has made these unmanned machines popular, and a family can even plant hundreds of acres of land.

Moreover, tens of thousands, 100,000 estimates are also very large, which makes the population area of the entire Northeast Plain far less dense than Li Ke thought.

However, it is good that it was once glorious, and then it is always unacceptable to fall, but with such a development based on agriculture and the establishment of the main positioning here, there will not be so many problems.

After all, with the scale of Datang now, the development of the whole industry chain is a must, and the industrial aspect is also dominated by all aspects, such as the oil industry, almost all of which are concentrated near the Arab state of Zhonghua, where although the overall environment is harsh, but the amount of oil output is huge, and the natural oil industry is easier to develop.

Industries such as natural gas will naturally begin to flow with the construction of gas pipelines, and industries such as automobiles must rely on relatively densely populated areas for construction, after all, the automobile industry is also a labor-intensive industry in the early stage.

Therefore, Datang's current industries are basically distributed in different states of Datang according to different types, and it can be said that each state has its own characteristic industry, which is normal.

If you think of these states as a country, it's easy to understand.

It's just that there are no tariffs between countries, trade restrictions, etc., and on the whole it still has a lot of advantages.

Therefore, for example, in the northeast, although mineral resources are also abundant, many mineral resources have only been detected and have not been mined.

Obviously, this area in the northeast, as the only black soil in Datang, is of course the most suitable for the development of the grain industry.

Wheat, rice and other industries are booming here.

Similarly, forestry resources are abundant, and there are many other wild resources.

Concentrate on resource industries, so that although there is no heavy industry here in Northeast China, it is no longer like it was an industrial region in history, but its GDP is not low, and its per capita income is also not low.

The right path is the most complete, these developments are obviously not Li Ke can arrange, after all, after more than 1,400 years, how to develop, how to develop, all after a long time of adjustment.

Coming here, Li Ke also noticed another point, that is, it is like the biggest specialty of Silla State, which is actually spicy cabbage and kimchi.

This made Li Ke completely speechless, after two worlds and more than 1,400 years of history, it has not changed, which is outrageous.

In Liaoyang City, it has to be said here that Datang does not have Shenyang City, because after the establishment of Liaoning Prefecture, it was called Liaoyang, and then Liaoyang gradually developed, and it has become the largest city in Liaoning Prefecture and the seat of the county capital of Liaoning Prefecture.

In Liaoyang City, Li Ke saw a large number of Silla specialties, kimchi and spicy cabbage.

The main thing is that the assistant bought a lot for her family, saying that her mother likes to eat, and this place is the closest to Silla State, so it is the most authentic.

Li Ke can also be regarded as following the little assistant to learn about the industry of Silla State.

The spicy cabbage industry was concentrated in Silla because after the Tang Dynasty won Goguryeo, the Chinese cabbage was also introduced to Silla, and for the people of Silla, the Chinese cabbage at that time was life-saving from a certain point of view, just like the food supported by the Tang Dynasty.

Because Chinese cabbage is one of the few important food supplements for their ordinary people, and the pickles that can be eaten in winter are mainly spicy cabbage, and a large amount of cabbage can also be stored in the cellar.

For these reasons, industries such as spicy cabbage once again became a specialty of Silla State, until it has been passed down to the present day, and because of the characteristics of the Silla people, and later because of the influence of Li Ke, they thought that this spicy cabbage was given to them by the Holy Father, and it was treated as an industry.

In addition, at that time, the entire Northeast Plain was mainly planted with wheat, and unlike winter wheat in the south, spring wheat was planted in spring in the Northeast and harvested in mid-July.

After harvesting, Chinese cabbage can be planted in the wheat field, and by the end of September and early October, the Chinese cabbage can be harvested.

The land is used to the extreme, and this is naturally a very important place to sell Chinese cabbage, after all, it is close to the entire Northeast production area.

Therefore, although the production area of Chinese cabbage is not in Silla, the manufacturing plants of spicy cabbage are indeed concentrated in Silla.

Fortunately, after all, Silla is also from Datang, so the current Datang Silla, meat, fruits, watermelons and the like are not bought piece by piece.

Li Ke was also a little helpless, and could only be described as the world line constraints.

Liaoyang City, the city wall here is still intact, not only the city wall, but also the section of the city wall that was blown down has not been repaired.

After taking this place back then, there was a willingness to repair it, and later considering that the future development of Datang actually did not need the city wall, so the gaps in these places were naturally not repaired, but only sorted out.

Later, after the city wall was protected, these places were even partially restored, and some broken city wall bricks were piled up again anyway.

To this day, it still retains its original appearance.

But...... Li Ke is sure that the city bricks and so on here are definitely not the same batch as they were back then, and if the entire city wall is kept intact and continuously maintained, it can be maintained for more than a thousand years, but it is almost impossible to maintain it for more than a thousand years after the collapse.

So, these things were obviously placed later, but it doesn't matter, such an attraction can let people know what really happened at that time. These are just things that the local people use to maintain the tourism economy.
