In the evening, Yuwen Wen, who had been busy for a day, had nothing to do and fiddled with a device in the study. This device is a bit special and can produce high-frequency vibrations and last for a period of time, so it has a name called a vibrating rod.

Vibrating rods are the names of two types of products in later generations. This thing in Yuwen Wen's hand is a model of industrial vibrating rods (principle display machine), powered by compressed air.

As for another vibrator...

Yuwen Wen thought that it was really a "strange trick" and was not considered.

Vibrating rods driven by compressed air are very useful in engineering construction, especially when using concrete to pour components. In order to drive out the bubbles in the concrete as much as possible and make the concrete densely combined, the vibrating rods can be used to achieve the purpose.

After more than 30 years of development, the cement industry and its application technology (concrete) have become very mature. As more and more construction projects use cement, new tools such as vibrators have also become available.

The application range of building materials such as cement, bricks, and stone is becoming more and more widespread, and the proportion of wood in building structures has decreased, which is the decrease in the chance of fire, and the wood replaced in daily maintenance is also much less.

This is a ripples caused by technological progress, affecting all aspects of social life, but when it comes to influence, there is one thing that has a greater impact.

Zhang Lihua, who came in with information, talked to Yuwen Wen about the trend of coal prices in Chang'an. She was responsible for the royal coal industry (account management), so this topic was most appropriate.

A few days ago, the first phase of the Guanzhong Railway (East Section) was completed and opened to traffic. Yesterday to this morning, twenty coal trucks arrived in Chang'an smoothly from Weikou, so the coal price in Chang'an fell accordingly.

Since the beginning of this year to today, the coal price in Chang'an has dropped by 30%, which is an incredible drop.

Zhang Lihua introduced this: "There are three reasons for the decline in coal prices. First, the emergence of new coal mining technology has caused a significant increase in coal production in Hedong, and the increase in coal supply market will naturally lead to a decline in coal prices."

"Secondly, the Guanzhong Railway is opened to traffic, and the freight transportation volume from Weikou to Chang'an will inevitably increase significantly, so the Hedong coal accumulated in Weikou Port can arrive in Chang'an more quickly, which also causes sufficient market supply and lead to a decline in coal prices."

"The third is that the Guanzhong Railway is open to traffic, and the cost of railway transportation is extremely low, not only less than carriage transportation, but also cheaper than canal transportation."

"So, railway transportation is the main reason for the decline in coal prices in Chang'an. This is just the beginning. With the end of the trial operation of Guanzhong Railway and the official start of freight, the price of coal in Chang'an will continue to fall..."

Zhang Lihua took out another piece of information and began to introduce the impact of the decline in coal prices on Chang'an prices.

After twenty years of development, coal has replaced firewood and charcoal and has become the main fuel in the daily life of residents in Chang'an City. Honeycomb coal and coal balls have entered thousands of households. Therefore, when the coal price drops significantly, the cost of living for the people also "reduces".

The cooked water shops that have been spread all over Chang'an City provide residents with a large amount of boiling water, hot water and tea. Because the boiling water boiler burns coal, and the coal price has fallen, the water price of cooked water shops has dropped.

Similarly, the tea prices in various tea shops and restaurants have decreased. According to the survey results of Yousi, the sales of cooked water shops and tea shops have increased by about 20% year-on-year in total compared with last year.

For small restaurants that provide breakfast (阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿阿�

The impact of this is that people who "work" in various workshops and workshops prefer to buy breakfast on the way to work rather than cook at home. Such changes have also begun to appear in ordinary residents' families.

Due to the reduction in fuel prices, the cost of small restaurants has been reduced. Many stores have extended their business hours from morning to afternoon, while the number of small restaurants and even vendors has increased significantly.

This means that many working families have the ability to ensure three meals a day.

Since ancient times, two meals a day (morning food, evening food) have been the dining habit of ordinary people. But now, because the prices of various foods in restaurants are low, many families can add a lunch between morning food and evening food.

Morning food and lunch are all solved by purchasing food from restaurants or vendors. When it is evening, you can prepare your evening food at home.

This is an ordinary people's livelihood, and rich families, because the coal prices have fallen, use "air conditioners" and the cost of fans has decreased. Since the beginning of summer this year, the "installation volume" of "air conditioners" and fans has increased by about 30% year-on-year.

This situation is only one of the impacts brought by the decline in coal prices (decreased living costs). Zhang Lihua used this as an example to explain to Yuwen Wen from one aspect (coal prices) the impact on residents in Chang'an City after the railway is opened.

Railway transportation has greatly increased the capacity of land transportation but significantly reduced the cost, not only coal, but also other goods and commodities.

The cost of living for the people is declining, and the increase in employment opportunities (large recruitment of workers in workshops and workshops) has increased, which has increased the income of working families, so they have the remaining money to consume appropriately, and the catering industry and even the entertainment industry have flourished.

This is the change brought about by railways, and it is only the beginning.

Speaking of this, Zhang Lihua sighed: "The railway is really a good thing, it's expensive."

"It doesn't matter if you are expensive, just be worth the money. When the train runs, you can slowly make money back with the profit." Yuwen Wen smiled, put down the information, and calmly drank tea.

"But railways are really expensive..." Zhang Lihua sat next to Yuwen Wen and poured tea for him. "In order to sympathize with the people's strength, the railway construction teams are mainly used to hire labor, and they hire construction teams, people, and spend a lot of money to buy raw materials. The money spent is calculated in millions of yuan..."

"Although these expenses are supported by the gold and silver earned by the sea trade, but, but..."

Zhang Lihua probably knew how much real money the imperial court had paid for this Guanzhong Railway (East Section) was built so quickly. In fact, she felt that it was not necessary, but she was afraid that Yuwen Wen would be unhappy if he complained too much.

"Can the gold and silver earned from the sea trade be stored in the warehouse? " Yuwen Wen asked back, without waiting for the other party to answer, and asked again: "How much profit can it bring to create jewelry? Do we need this thing to dress up the storefront?"

"You also know that money can only be circulated to create more profits, and gold and silver can only be used to prove their value, but there are some usages."

"If you buy things directly, such as buying luxury goods, you will not be able to create too much profit. Why do you think this is?"

Zhang Lihua thought for a while and replied: "After the merchants collect gold and silver, they may not use it easily anymore, but will only save it. Therefore, the circulation of gold and silver has come to an abrupt end and cannot create too much profit..."

Yuwen Wen nodded: "Yes, but it's different to buy a product called "Infrastructure".

"The gold and silver that have been spent becomes a railway, and there are trains running on it. When the train whistle sounds, wealth comes with it."

"The low transportation costs have caused the prices of various materials in the areas along the railway to reduce the cost of living, and the cost of living of the people can consume more goods, thereby promoting the development of industry and commerce. Such benefits can not be bought directly with gold and silver."

Speaking of this, Yuwen Wen stroked Zhang Lihua's smooth cheeks and sighed: "Besides, don't think that too much gold and silver in your hands is a good thing. If the operation is not properly done, it will lead to inflation. This is not a joke."
