So why couldn't the Great Song Dynasty develop a truly practical four-wheeled carriage? Is it so hard to have a small steering device?

There's a reason for that. Pen % fun % Pavilion www.biquge.info

During the Southern Song Dynasty, the land where they lived had a large number of rivers and long flows. There are more than 50,000 rivers with an overall basin area of more than 100 square kilometers, 1,580 rivers with an area of more than 1,000 square kilometers, and 79 rivers with an area of more than 10,000 square kilometers.

This continent is about the size of Europe and the United States, but there are far more rivers than Europe and the United States.

Its topography is high in the west and low in the east, the river direction is mostly east-west, the east-west waterway transportation is convenient, although the north-south direction lacks large rivers, but the major rivers are mostly tributaries in the north-south direction, and the tributaries are parallel to each other and evenly spaced.

In particular, the opening of the Beijing-Hangzhou Grand Canal has solved the problem of north-south transportation in the eastern region, although there is no large north-south canal in other regions, but the short distance between the tributaries makes the demand for four-wheeled carriages used for long-distance transportation on land is not urgent, and the natural conditions prompted the ancient people of this continent to be more inclined to solve the traffic problem through water transportation.

Moreover, no matter how much the four-wheeled carriage may have increased its carrying capacity compared with the two-wheeled carriage, the carrying capacity of the two instruments is very different from that of shipping, and it is more economical for shipping to rely on the power of nature than for horse-drawn carriages to rely on animal power. Waterway transport does not require the creation of dedicated transport hubs, and cities and villages along the river can become natural supply stations.

Therefore, the Southern Song Dynasty mainly aimed at water transportation, established a huge and complex waterway transportation network, and developed advanced shipbuilding technology, which made land transportation, especially long-distance land transportation, not pay attention to, or say, unnecessary.

There's also the issue of the cost of shipping.

This continent has had the concept of "family in the world" since the Zhou Dynasty, and although they were divided into feudal feuds during the Spring and Autumn Period and the Warring States Period, they were still the princes under the Emperor of Zhou. Since the Qin Dynasty, a unified state has been established, and although it has been divided from time to time since then, unification has remained the main axis and the goal pursued by successive rulers of successive dynasties. One of the major problems these rulers faced was how to achieve a fast and efficient movement of goods over a large area and in large quantities within an empire of such a vast territory.

The ancient European states were small and populous, and the four-wheeled carriage could quickly meet the relatively long-distance and large-volume transportation within the national limits, but this was not enough on this continent.

Bulk goods, especially military transportation and taxes, because the ancient taxes and taxes on this continent were mostly paid and distributed in kind, and if long-distance transportation was completed by four-wheeled carriages, the cost would be far greater than that of water transportation, and the cost was really high.

This situation also caused the people of this ethnic group to lose interest in the large-scale use of horse-drawn carriages for land transportation.

These may also be the main reasons why horse-drawn carriages, especially four-wheeled carriages, have not been used on this continent, and of course, differences in road paving technology and vehicle manufacturing processes have also had an impact on this result.

Anyway, they can be regarded as making up for the shortcomings of this technology for Da Song, but whether Da Song can care about this technology or not, they don't care.

In fact, they can also take a boat to Lin'an Province.

In the past, Yalang Ma Yun introduced to everyone: "If you pass through Nantiaoxi, you can directly release the boat to Lin'an Mansion, and the road will be calm and calm......

By water? They thought about it and gave up.

They feel that their combat strength can only be brought out best on land.

If this level reaches the water, it will suffer a big loss, and now is not the time.

This time they brought some "boutiques", which must be easy to sell, not a lie.

The first type of treasure is the artificial luminous stone.

Artificial luminous stone is a high-tech self-luminous product that uses alkaline earth aluminate, silicate, etc., activated by rare earth elements.

Natural luminous stone cannot be used in fields such as home decoration because it contains a large amount of radioactivity.

But artificial luminous stone is a good thing, it is not radioactive, it is non-toxic and harmless to the human body.

After absorbing all kinds of visible light for 10~20 minutes during the day, it can continue to emit light in the dark place for more than 12 hours, and its luminous brightness and duration are 30~50 times that of traditional ZNS luminous materials, and can be recycled indefinitely.

It is made of resin or porcelain as the main material and added luminescent raw materials for special process treatment, forming after natural molding and mold molding, and is a high-quality material for modern plastic art and grooming guidance.

So, this thing is not worth much, in that world, if you want to sell it in kilograms, forty or fifty yuan a catty.

If the people of the Great Song Dynasty carry it on their bodies, they must have the characteristics of the clothes of sanitation workers, and they are also like the kind of night light on the traffic police.

They're going to be super loving and not heavy.

Of course, they also choose to wear pieces that can be hung on their bodies in advance.

The second treasure is artificial crystal.

They originally wanted to take some pearls to Lin'an Mansion, but after the previous transaction, they found out that this was a Great Song who preferred stones, and they were immediately reluctant.

Want stones? Brother has, it's all man-made.

Artificial crystal is lead glass, of course, it is much stronger than natural crystal and glass in terms of transparency and refraction, and it is estimated that their crystal ball can make the Great Song people crazy.

Of course, when they bought it, they carefully picked it, and they were all the best products without impurities and bubbles, and they were more expensive, hundreds of dollars each.

If this is done on a moonlit night, let the scholars and doctors stroke the crystal ball in the courtyard and absorb the essence of heaven and earth...... It's a great tool for meditation.

The third treasure is some square Dongshan crystal mirrors, which are larger in size, and they use hay to cushion them in the box, and they are not afraid of shocks.

Others, such as matches, are small, bits and pieces.

After making the four-wheeled/big donkey cart, they tried the test drive, and it was okay, and the donkeys were very cooperative.

Those Da Song technician students were so happy, they drove around in their cars when they were idle and had nothing to do, just right, let them run in for themselves.

Graphite is a natural powder lubricant, so the noise of the car is small.

Seeing the children driving four-wheeled vehicles and interacting with donkeys, Zhang Guoan said to Wu Dapeng: "Take two students, you can sit in the car, you can see that they can almost catch the car." ”

Most of these students have worked in Lin'an Mansion and are familiar with the situation there.

They have already sent Yalang Ma Yun out to focus on various fuel problems.

Wu Dapeng said: "Okay, I'll pick two people, one is Bao Wei and the other is Guo Beyu, listening to their usual conversations, it seems that they are more familiar with Lin'an Mansion." ”

Song Ziqiang also confessed when he left.

This winery must be built quickly, he is fed up with this muddy wine, and this is also a business, in addition, Zhang Guoan will still need alcohol in the future.

And they all planned that the main raw materials for alcohol in the future would be sugar beets or other fruits.

Beets are made up of wild species that originated on the shores of the Mediterranean. After a long period of artificial selection, it slowly evolved, and by the 4th century AD, white beets and red beets appeared.

In the 8th ~ 12th century, sugar beet has been widely cultivated in Persia and ancient Arabia, and in a few hundred years, it will spread to China.

They brought with them the seeds of sugar radish type sugar beets that are suitable for cultivation in the south, which is more suitable for various places in the south.

Of course, beets are more suitable in the north, and where there is a large temperature difference between day and night, the sugar content will be higher.

But this one is also suitable in the south, the sugar content is not as high as that of sugar cane, but its leaves are still edible, and it is more labor-saving to manage.

The wine of the Southern Song Dynasty really made people who were used to drinking high alcohol unbearable, it was too watery.

Mo laughs at the farmer's wine, and most of the so-called muddy wine is rice wine made from japonica rice by farmers.

The Southern Song Dynasty, like the Tang Dynasty and the Northern Song Dynasty, liked to drink, "there are many people, and there are many drinkers". At that time, there were four main categories of liquor: rice wine, fruit wine, blended wine and liquor.

Rice wine is made of cereals, "all the brewing of japonica, glutinous, millet, millet, wheat, etc., and the koji wine style are suitable for water and soil".

When they arrived in the south, they replaced millet with glutinous rice and became the main raw material for sake brewing.

Fruit wine includes wine, honey wine, yellow mandarin wine, coconut wine, etc., among which wine is the most produced.

Six smugglers, maybe a new drink for them.

The so-called liquor of the Song people did not have the nature of distilled liquor, and it was called steamed liquor, soju or liquor dew at that time, and the "muddy liquor" that Lu You drank in Shanxi Village was probably soju.

Although there are many types of folk liquor in the Southern Song Dynasty, the production technology is still relatively poor, and most of them can only be made into turbid liquor.

Of course, in the homes of the official and the wealthy, with sufficient funds, raw materials and technology, it is still possible to make good wine, but it is difficult to see it in the market.

The official good wine is such as the "Fengquan" of the front division of the army palace, the "Ai Consultation Hall" of the Changping Division of the East Zhejiang Promotion, the "Huanghua Hall" of the Changping Division of the Zhejiang West Promotion, and the "Preparatory Hall" of the Jiangdong Operation Division, and the forbidden imperial wine, named "Rose Dew".

These wines are special wines, and ordinary people cannot drink them.

Otherwise, they wouldn't be able to think about making their own wine.

A broken distillation technology is so difficult to break through!

So Song Ziqiang designed the distillation kettle, which is actually a distillation equipment with a copper and wood structure, and each part was drawn one by one, and the data was also marked, so that Zhang Guoan could find a craftsman to make it.

This time, we will start building a few brick houses.

There will also be a heat treatment workshop......

In short, in the plan, waiting for the four of them to come back from Lin'an Mansion, the construction must be basically completed here, and the raw materials must be prepared.

It was a beautiful morning before departure, the sky was blue, and there was not a trace of white clouds.

The four professors entered the carriage one by one, and after the carriage trembled, they also sat down one by one.

The two students sitting side by side in the driver's seat, Bao Wei and Guo Beyu, proudly shouted "Drive!" ”

The six donkeys understood, and set out.

Donkey carts are much easier to handle than horse-drawn carts.

Zhang Guoan and quiet, and a group of students watched from afar as they disappeared around the corner of the road.

Zhang Guoan thought, okay, come back quickly, my friends.

But in terms of time, they may have to spend their first Spring Festival in the Great Song Dynasty space in two places.

The Song Dynasty is an era of inheriting the past and opening up the future, many of the Chinese's Spring Festival customs began in the Song Dynasty, and the year of the Great Song Dynasty also has a strong festive atmosphere, and they will want to feel it well.

Fortunately, the New Year in the Great Song Dynasty is similar to that world, with family reunions, drinking, eating slots, setting off firecrackers, and New Year's greetings.

It's just that the content of the spontaneous organization of the Chinese New Year in the Great Song Dynasty is richer, such as folk performances, fireworks, lanterns and many other entertainment activities, which will definitely be lively.

Guo Beyu kept trying to snatch Bao Wei's donkey whip, but Bao Wei didn't give it.

After the two had agreed, Bao Wei agreed to let him go when he returned.
