Everyone was very strange, the little emperor talked about almost all the things that had nothing to do with the war in one afternoon, and it seemed that they were inseparable from the war. The most talked about are logistics-related matters, including not only the supply, transportation, procurement, and production of materials, but also the details of soldiers' clothing, food, housing, and transportation, and they attach great importance to it, so that everyone has to work hard to solve them.

In fact, Zhao Hao was only patrolling the camp when he overheard two soldiers on duty complaining, they felt that this year's winter was surprisingly cold and extremely difficult, which made him wake up suddenly. As early as the time of Qiongzhou, there were no four seasons, almost all of them spent summer, and naturally they would not consider the problem of cold protection. After entering Jiangnan, the climate has four seasons, and the issue of cold protection is also on the agenda. However, he heard the complaints of the soldiers and realized that although he had taken certain measures to protect himself from the cold, the military uniforms were divided into winter and summer, and the barracks in the north area were equipped with heating measures, but it was still not enough.

As we all know, China takes the Huai River as the dividing line between the warm and cold zones, and for a long time, there has been a deep misunderstanding between the north and the south -- the south is not cold. Zhao Yu lived in the south for many years in his previous life, but he was deeply touched by this, when the temperature is right, people do not feel the trouble caused by humidity, but in the winter in the south, clothes become always damp because of the heavy moisture in the air. Not only does it not have the effect of keeping warm, but it also robs us of all the meager heat, not "clothes warm people", but "people warm clothes", if a little wind blows, it is absolutely cold and the heart is flying.

However, Zhao Yu felt that he could still survive the short winter by wearing thick clothes at that time, but after he came to this world, he felt that it was colder than the winter in his previous life. And the past two years seem to have been colder as the two soldiers said, he received a report from local officials that this year, because of the cold weather, the agricultural season has been somewhat postponed, not only in Hubei, where there is not much snow, but also in heavy snowfall, and even in Guangzhou, there is a light snowfall.

In Zhao's previous life, some people believe that the fall of the Yuan and Ming dynasties was related to the change of the earth's climate, and it was precisely because of the arrival of the Xiaoice period that led to the various Mongol Khans, from Iceland and Britain at one end of Eurasia to Japan at the other end, all countries suffered from plague, famine, reduced agricultural production, population decline and social unrest, and almost no society was immune to some of these disasters. China was not immune, which led to a rise in social contradictions, which inspired peasant uprisings and the southward movement of nomads, leading to the change of dynasties.

It is still decades before the fall of the Yuan Dynasty in history, but the cold wave has invaded the always warm Jiangnan, which makes Zhao Yu a little confused. I don't know if it was because he changed history, caused God's revenge, deliberately embarrassed him, or the prelude to the coming Xiaoice River period. However, the abnormal fluctuations in the climate have caused him great trouble, and may bring variables to the great cause of his unification.

At present, the Great Song Dynasty only occupies the south of the Yangtze River, and if it wants to achieve unification, it must attack from the south to the north, and the soldiers must be from the people who have lived in the south of the Yangtze River for generations, and they have poor adaptability to the cold northern climate, and it is an extremely challenging task to go to the north to approach the cold zone or even fight in the cold zone. So the question is, how to deal with this bitter cold and blizzard?

Historically, even for many Central Plains dynasties, fighting in winter has always been something they tried to avoid. The reason for this is that the winter march is naturally hindered by heavy snowfall, which not only affects the march of the soldiers, but also causes difficulties in logistics and transportation. And in many northern wars, especially the wars of the Central Plains Dynasty against ethnic minorities further north, the cold itself was a great obstacle.

Zhao Yu knew that in history, Tang Taizong personally conquered Goguryeo, because of the arrival of late autumn, Tang Taizong was worried about the logistics in winter, so he hastily withdrew from the army. In addition, in the Battle of Dachangwon between the Mongols and the Jin Dynasty, the Red Turban Army conquered Goryeo for the first time, and both the Jin Army and the Red Turban Army were defeated because the army did not adapt to the cold winter. Even in modern times, Napoleon's defeat in the Russian conquest can be regarded as a bloody lesson for fighting in the cold season, which shows the terrible impact of winter on war.

It is precisely because of the large number of uncertainties brought about by the cold winter that the commanders of the armed forces must be more cautious and careful in dealing with every problem that may be encountered in combat, but this still does not guarantee foolproofness. Although winter is indeed a big problem, for the army, it is not that they don't want to fight in winter, so they don't have to fight in winter. Therefore, it has always been a very important matter to solve the negative impact of cold on war.

For the winter operation, Zhao Yu thought that there were undoubtedly two important issues to be corresponded, one was how to ensure stability in the later stage; The two are how to keep the soldiers warm. He believes that in fact, the former is much easier than the latter, and he can use the cooperation of the sailors, on the one hand, to advance by water and maintain a strong offensive; On the other hand, the sailors can also be used to ensure the supply of the army. The most difficult thing is how to find a kind of warm fabric that is qualified and has enough yield.

In modern times, even for the poorest families, the bitter cold of the northern winter is not a cause for concern – a cotton coat is all it takes; If one doesn't work, then two. However, at the same time when it is cold and cotton fabrics have not yet become popular, winter is indeed not so easy to pass, especially in the northern regions, because it is still far from the popularization of cotton cultivation at this time.

What Zhao Yu learned is that from ancient times to the present, China's traditional textile industry is mainly based on silk and linen. Before the advent of "silk and hemp", people mostly used animal fur to make clothes to protect themselves from the cold. With the progress of the times, in the pre-Qin period, hemp and kudzu fabrics began to appear. The most important of them are kudzu, marijuana, ramie, ramie, etc.

The ancients mainly used kudzu to make ropes and clothes, but because the texture of kudzu cloth is thick and thick, and the effect of moisture absorption, heat dissipation and warmth is low, the ancients mostly used kudzu cloth to make summer clothes. The plant fibers of hemp are likewise long and tough. And hemp and kudzu are also easy to source, linen has a uniform texture, simple color, soft feel, and is still an important clothing material. Coupled with the characteristics of low price, it became popular quickly, and ordinary people could basically wear clothes made of kudzu.

However, Zhao Yu also knows that although the price of hemp and kudzu is close to the people, their cold protection effect is still unsatisfactory, and people still have to rely on animal fur to keep out the cold in winter. Fur is a very expensive thing in any dynasty, and mink fur is not something that everyone can afford to wear. So, how did those who couldn't afford fur coats survive the winter?

Since kudzu and hemp alone do not keep warm, fill the clothes with silk wool to keep warm. Of course, high-quality silk wool is not something that everyone can afford, so ordinary people can only use some old broken wool mixed with some leftover scraps of silk reeling as warm filler - also known as "silk wool". The robe was clearly not a high-end item - it was not as good as it could have been and it was easy to break.

Therefore, crossing is also a technical job, if you accidentally come to the era without cotton, and you are born in an ordinary family, then you must be prepared to freeze to death. Zeng Zi in the Warring States period also wore a robe, and when he raised his arm in the cold winter, the sleeve was broken to expose his elbow, leaving an allusion of "overstretched". And if you want to spend the winter in peace of mind, you either wear a low-quality robe, or a cheaper dogskin robe, then you still don't have to think about mink fox fur.

When Zhao Yu came to this world to celebrate being born in the emperor's family, he also discovered a surprising thing, someone actually had to wear a 'paper clothes' for the winter. It was the winter of the year when Jiangnan had just been recovered, and the household department asked for an order to allocate silver taels to help the poor, one of which was to make paper clothes. You can imagine his shocked appearance when he saw it, in modern society, no one will wear paper clothes except for models and those so-called avant-garde artists, and I am afraid that I can't imagine a big hole in my head to keep out the cold with paper clothes, but it appeared in the so-called rich Song Dynasty.

If you make a dress, a quilt, out of paper that is now light and brittle, you will definitely have serious doubts about its usability, let alone warmth. The paper of the Song Dynasty is mostly made of bark as raw material, tough and thick, strong tensile force, folding and wear-resistant, as long as a certain thickness and pulping degree are controlled, it can be made into cheap and can be made of paper clothing raw materials that can block rain and dew and wind cold. The paper clothes contain hemp wadding, and they become paper jackets. If you make it bigger, it will become a paper quilt.

At first, wearing paper clothes was just a helpless move for poor people who had no cloth to wear, that is, they took a few pieces of paper and glued them together to protect themselves from the cold. It is precisely because of the low price and ease of making paper clothes that the distribution of paper clothes to beggars in the market in the harsh winter season has become an official poverty relief measure in the Song Dynasty, and some institutions directly distribute paper quilts to save money. Lu You has a deep understanding of the warmth brought by the paper quilt on a snowy day, and he once wrote a poem to thank the friend who gave him the paper quilt, and exclaimed, "The paper quilt is surrounded by snowy days, and the armpits are as white as the fox armpits." ”

The whiteness and softness of the paper material is also quite in line with the aesthetic taste of the literati doctors of the Song Dynasty, and wearing paper clothes and covering paper quilts even became a fashion in the literati circle at that time. If the paper is dirty and old, squeaky, the big life Su Dongpo teaches you how to deal with it, "The paper is old and hairy, it will be broken, with five or seven yellow hollyhock stems, crushed, soaked, saliva brushed, then as new, or with hibiscus leaves to pound water, brush, also wonderful." ”

But since paper clothes and paper quilts are helpless emergency measures, they must be imperfect, and their biggest problem is that they are not breathable, and long-term use is not good for the body, so they have to change cloth clothes and paper clothes for cold protection in winter. Of course, the shortcomings cannot be used to equip the army, although there has been a 'paper armor', but the manufacturing process is more cumbersome, and the price is not cheap, it is by no means the kind of Lou goods that are rumored to be filled because of insufficient military spending.

As a means of keeping out the cold, most of the armies also used quilts and cold-proof clothing made of animal skins or linen wrapped in silk wool. However, the low yield of both was a problem that had been difficult to solve for a long time, so silk silk has always been an important part of the tax in kind levied on the peasants, in order to ensure the supply of the government and the army. But even so, it is still difficult to maintain a military presence in the higher northern latitudes for a long time. Therefore, the actual control area of the Central Plains Dynasty rarely exceeded the Liaodong region in the north......

The current situation made Zhao Hao realize that if he wanted to solve the problem of 'keeping warm', he could only place his trust on cotton, but to solve it, he must not only put it in front of him, but also consider it from a strategic perspective, otherwise the unification of the whole country can only stop at the line of the Great Wall.

In fact, cotton was first introduced to China as an ornamental flower, and as late as the Han Dynasty, cotton appeared on the East Asian continent. However, from the Han Dynasty to the Song Dynasty, cotton cultivation was always confined to southern China and the region, and the development of related industries was also very slow. And Zhao Yu is no stranger to cotton in this era, cotton has been planted in Qiongzhou, and has formed a mature textile technology, and has become an important export product in Qiongzhou, but the price is amazingly high, can only be used as a luxury, difficult to popularize.

As a later generation, Zhao Yu knew that the glory of the cotton era was precisely due to a precedent opened by a woman who lived in Qiongzhou, that is, Huang Daopo. She learned the technology of the Li people to spin cotton in Qiongzhou and combined it with the textile technology of the Central Plains. After returning to Jiangnan, Huang Daopo continued to improve cotton textile technology, upgrade and develop new spinning wheels. As a result, China's cotton textile technology began to advance by leaps and bounds, and greatly promoted the promotion of cotton planting.

Cotton cloth is softer and warmer than linen and silk, and it is less difficult to weave, and it also saves the labor of planting mulberry and raising silkworms. So that as soon as it appeared, it was widely welcomed by the people, in the history of the Yuan Dynasty when cotton was just industrialized, there have been cotton cloth, quilts, cotton yarn, cotton jackets, cotton clothes, cotton blankets, cotton shirts and many other cotton fabrics, and the imperial court at that time even used cotton as raw materials to make a variety of military supplies.

On the other hand, since cotton fabrics were already an indispensable commodity for all households, the cotton textile industry began to expand rapidly. And Zhao Yu also knows that it is the rise of the cotton textile industry that has had a profound impact on the social economy. As a necessity of life, cotton is very suitable for independent production by individual families, which has led to the fact that since the Ming Dynasty, China's self-sufficient natural economic system has become more introverted and stable, while the West has completed the germination of capitalism with the help of industrial production of cotton.

Although Huang Daopo doesn't know where it is now, Zhao Yu is not worried about it, Qiongzhou is his base camp, and manpower and technology are not a problem. The improvement of textile equipment is not an obstacle for him, this is what he is good at, he does not need to spend much energy to complete the upgrading of the original textile machinery, and can use his power to carry out factory production, and maybe change the course of the times. And there is no obstacle to large-scale promotion and planting for him, after all, he has a huge state apparatus in his hands, and an edict can do it......
