Trade is inherently profitable, and the size of the profit depends on the size of the cost and the demand of the buyer.

The cost includes a lot, simply put, the cost of production technology research, the cost of means of production, the cost of labor, the cost of publicity, the cost of transportation, and the cost of taxation.

Is the cost of goods sold by Datang merchants to other places high? Naturally it is not high, if you really want to say that it is high, it is high in technical research, and there is insurance in transportation.

The profit is not a lot because the demand side does not have the corresponding technology and wants to have it. In the face of such a situation, it is not the businessman who does not raise the price, but the philanthropist.

As soon as some people advertise, it doesn't matter who can afford to sell them, the watches produced by Datang are luxury goods, they want to buy cheap ones, but they don't want to buy them locally, and when they can't buy them in person, they want the price of goods to rise gradually, especially the goods they already have.

Even a person who does not understand economic and social ******** knows that to own luxury goods is to have status.

If you need to exchange a watch for a hundred sheep bought today, tomorrow the same watch will become eighty sheep, and the day after tomorrow it will be sixty.

As a result, the watch does not sell, no one buys it, even though it can tell the time, even if it is beautiful. But it is depreciating, not only in terms of the number of sheep, but also in the identity and status of the owner.

People who can't afford Datang goods consider the opposite, they can't compare with the rich and status people through their own efforts, so they hope to make the rich and status people lose through other means. The general idea of social individuality, regardless of system, is very complex social relations, and is very simple social psychology.

The people behind the bad people also look for the latter and tell them the actual situation. They can't afford it, but they will be as critical and accusatory as consumers who are going to consume it, accusing Datang merchants of selling cheap things to them at an expensive price and making them pay more.

They will protest, they will demand, let the Tang merchants lower the price.

It is impossible for Datang merchants to reduce prices, they have to protect the interests of the rich and powerful people in the place where the products are purchased, and they also want to maintain their own profits.

So those who want to sabotage continue to propagate, so that those who can't afford to buy things accumulate emotions and prepare for the moment of explosion.

Even if the bad people clearly know how strong Datang's military strength is, and they clearly understand that people from exploited places will be severely punished for attacking Datang, they still have to do it, just to be able to block Datang.

Among them, the Japanese are very much, Silla has been packed up without the slightest strength, and because of the border, land and sea connections are frequent, many locals have moved to the Tang Dynasty, naturally, there are also Tang people colonized the past.

The Tang people do not colonize casually, not because they are incapable, but because they colonize the past, they are afraid of independence in the future. The military strength of the Tang Dynasty is not good, which is mainly reflected in the lack of short-term long-range strike capabilities, so it is not allowed to colonize casually.

Even if the colonized place can have military strength, it is not allowed to have ordnance manufacturing equipment and technology.

There are colonists in Japan, and there are officials sent by China, and they take the Japanese to govern together, drawing small areas, many Japanese have accepted their fate, or they like their current life very much, and feel that if they cooperate with the Tang officials, life is at least better than before.

However, Japan is close to the Tang Dynasty, and its culture has been inherited well, and it is not so barbaric that it can't even have its own words. In the process of development, Datang traded with Japan, especially in the early dormant years, Japan sent people to Datang to study, and trade was frequent.

With culture comes thought, watching the rapid improvement of Datang, they also want to learn, and they also want to take advantage, learn to learn, and find that Datang began to invade them, a more terrible invasion than an invasion by force.

The new invasion model did not make them understand at first, and by the time people of insight found out, the economic and cultural invasion of the Tang Dynasty had basically been stabilized, the people in power were corrupted, and a large number of people were brainwashed.

People of insight were unwilling, launched many uprisings, and all of them were crushed, seeing Japan fall into the hands of the Tang Dynasty day by day, these people began to change themselves in order to take revenge and for the little luck in their hearts.

They no longer hold uprisings, nor rebellions, they try every means to come to Datang, do coolies, do small business, and even some women go to **.

They make money, they study, and what they actually want to do most is to kill Zhang Xiaobao and Wang Juan, and Zhang Xiaobao is in first place. They knew that Wang Juan was also very powerful, but he usually referred to military command and basic teaching, and Zhang Xiaobao was the leader and planner of the new invasion.

Some of them are doing things near the port, and they have seen with their own eyes that every time they get Zhang Xiaobao's order to transport grain from Datang Port to Japan and restrict grain transportation, Japan will lose a lot of money, and it seems that the loss is currency, but Datang does not want Japanese money, not at all, it is ordinary businessmen who do not want it, they will use money to buy things back.

For every loss, there must be an outflow of resources. People of insight in Japan have summed up that the most affected by the outflow of materials is the ruling power of the ruling class and the national culture of their own nation.

Any action ordered by Zhang Xiaobao himself will inevitably cause the Japanese people to be dissatisfied with the ruling class, and at the same time, they will be more inclined to Datang under the financial support of Datang's basic means of survival.

What a terrible act, what a Zhang Xiaobao who should be killed.

Half a year ago, a few people in their organization persuaded a powerful local quasi-ruler in the Kobe region to set up a money bank similar to the Datang Money Bank, absorbing the currency of the locals, hoping to find an opportunity to take advantage of the trade and currency exchange with the Datang Dynasty.

When the money village was established, it collected a lot of money, and the most important thing was that the Datang people also used collateral to borrow a lot at a low price, and the interest was very high, the interest rate was 2% for a month, and 24% for a year, catching up with the leap month more.

But a month later, the amount of grain transported to Japan by Datang decreased, and the largest reduction was in Kobe, and there was no trouble at that time.

Later, some people bought a lot of grain at high prices around Kobe, and until last month, people living in Kobe had to raise the price to buy it from others.

At this time, Datang's grain transportation stopped, and seeing that the main wheat producing area in the south of the Tang River was about to have a bumper harvest in a month, Datang said that the grain was not enough.

Half a month ago, someone suddenly went to Kobe's money bank to borrow a large amount of money from Kobe money bank with the wheat harvest half a month after Datang as collateral.

Before he could figure out what was going on, the quasi-ruling family in Kobe lent a lot of money to Datang, and as soon as Datang changed hands, he kept buying grain from Japan while exchanging Japanese money for Japan's Datang reserves.

And then...... And then what else to say, the purchasing power of the currency issued in Japan has become 30 bun, which is called depreciation, and internally it is called inflation.

The Tang people who borrowed money before did not repay the money because the loan date had not arrived, and other people ran wildly, and Kobe Money went bankrupt.

Datang began to downgrade the currency credit rating of Japan, where he and others were located. Fortunately, he and the others were smarter at that time, and before going bankrupt, they transferred the loan to the government of their own country in time, and the money borrowed by Datang still had to be repaid at that time.

But just yesterday, the day before the wheat mortgage expired, they repaid the money, including interest, and the money repaid was one-third of the actual purchasing power that was lent out, that is to say, two-thirds was earned by Datang.

This is not the end, today Datang announced a 10% increase in export tariffs on new wheat exports, the reason is not to bully people, not to say that you can adjust it if you want to, no, it is to say that Datang's currency has begun to inflation and its purchasing power has declined, so if Japan wants to use Datang money to buy things, it must follow the adjustment.

The problem is that your statement is based on your deflation some time ago, but why didn't you reduce export tariffs during deflation?

Together you put some of the losses of the deflationary time on us?

And all this, everything, is all Zhang Xiaobao, I heard that when he was looking at a new breed of pork in Sinong Temple, he said it casually, Wang Juan added two sentences next to him, so it became the current situation.

Can such a person keep him? A trade, a currency, we need to think and think, in order to understand the Tao in ignorance, the two of them seem to know the process and the result, and the means can be said to be familiar with it.

The most important thing is that Zhang Xiaobao's move has never been so simple, and now he is just squeezing and destroying a bank, earning two-thirds of the money, and earning another 10 percent of the grain exports.

But those who know him know that he will use a series of tricks, and this is definitely not the end, so this is where it goes.

So what we did before is right, we have to continue to do it, sabotage, we can't be beaten and don't fight back, it's just that we didn't do a good job last time, Datang seems to have taken advantage, but there is always a time to do a good job.

*****

The Japanese people of insight went on in a tangle.

It has been two days since the increase in export taxes, and Zhang Xiaobao and Wang Juan are going to the Ministry of Industry and the Research Institute today.

The weather is warm, the capital is still occasionally cold, and Jiangnan is already in a summer mood.

"In a few days, the lotus flowers in West Lake should bloom, Xiaobei and they are not in a hurry to come back when they stay there, come back quickly, and take them to Hangzhou to play." Zhang Xiaobao was thinking about travel, Xiaobei and they said, the potato harvest is good, so they are processing French fries over there, how long has it been processed, and can it still be processed?

"They want to let them play if they want to gallop there, and you still want to go out? I've heard that a lot of people want your life. Wang Juan asked with a smile.

"There are a lot of people who want my life, they have to have that ability, I don't play micro-service private interviews now, I go out with a large army, I still want their lives, don't think that what happened in Sumatra to attack our businessmen, I don't know who instigated it behind it.

If they succeeded, I would have counted them as good, and as a result, the hundreds of them failed, and gave us an excuse to intervene further by force and demand compensation from their country, as well as the opportunity to cede land for us to conduct military training and garrison.

If they have the ability to continue, whoever does it, I will cut the land of whose country, dare not give it, just destroy it, and want us to sell the goods cheaply? If we sell cheaply, the first to oppose us will be their comrades. ”

Zhang Xiaobao pursed his lips and said.

Wang Juan followed and said: "Don't mention the disturbing thing, today the research institute said to give us a surprise and see what is going on." ”
