"I just have enough money, and I still have to take it out if I have more." Li Yi doesn't care about making money from cotton processing.

"It's your own business to take it out, why don't you let you earn the money you should make?" Li Longji insisted.

"Earn it, earn it. When the weather warms up again, sell the bicycle, and there will be a large amount of money in the account, and you will not have to pay taxes. ”

Li Yi doesn't bother with cotton things, and talks about bicycles.

Li Longji asked: "Can a good bearing used in a unicycle make it easier to travel?" ”

"The value of bearings is far greater than that of a unicycle, so why should anyone who can use a new bearing unicycle push a unicycle?"

Li Yi smiled, this is the same as driving a supercar to deliver food, purely idle, in order to experience life.

And the wooden wheelbarrow is actually quite good, and the Huaihai Battle was pushed out with a small car.

Precious historical photographs show that people used horse-drawn carts, donkey carts, wheelbarrows, and burdens to support the front line.

At that time, wheelbarrows were wheels and axles made of wood, and where did the metal come from.

"Third brother, in fact, there is a way to speed up, and there is a wooden track in Chang'an City, like a track like Hukou Waterfall in the Yellow River.

Including iron ore and Chang'an wharf warehouses, a horse can pull a lot of heavy things and people at the same time.

As long as you don't get tired of the horses, the tracks crisscross the city of Chang'an, and the people have public transportation.

From the west of the city to the east of the city, how much goods to bring, according to the standard to give money......"

Li Yi began to introduce his new idea, public transportation.

A few years ago, people traveled from the west of the city to the east of the city, bringing a few packages, and he would not give him a penny for the fare.

He would rather go on his own, a penny is not easy to earn.

Now for the same package and journey, if you have one penny, the people promise that they are willing, and they can earn several pennies by saving time and effort to work.

Just like why the people in the counties of Jingzhao Province use steamers in summer and plows in winter, they feel that time equals money.

Like a greenhouse, light a candle in the morning before dawn to pick vegetables, and then cover the insulation and ship it to Chang'an to sell.

The speed is so slow that the local dishes are wilted, or is it a departure in the morning, it will arrive after dark, and it will be sold tomorrow?

You can only use a climbing plow to pull it, set off in the morning, rush to the place before noon, and sell it at a good price while it is fresh.

There are also people who work for the Li family Zhuangzi at home, and they spend money when they go to Chang'an and when they go back.

After two or three days, I didn't freeze to death, and then I went back with the same amount of time, how much less work?

"What about the crossing?" When Li Longji thinks of the track, he thinks of the horizontal and vertical cross.

"Leave a little gap, as long as the wheel is big enough, it won't fall in, it's just a little bump in the place."

Li Yi had seen the picture of the railway ten intersecting, so he did that.

"What if it's a turn?" Li Longji still has questions.

"Design the arc track, and the horse will be fine if it is well controlled." Li Yi doesn't think this is a problem.

He used to ride on a tram, and after a right-angled bend, he walked away in an arc.

"What about the charges?" Li Longji asked about the specific operation, and he had already decided to lay the track.

This thing is fast, as long as it is mobilized, the wooden rails can be paved in two or three days, and then the speed of the people of Chang'an can be improved.

You can even pave it along the main road to the counties of Jingzhao Province, and the horse-drawn rail car is fast.

But unlike Chang'an to Luoyang, that road belongs to the gallop road, and the car wheel is still the original car wheel.

The new one uses good bearings and is on the track, and one horse can pull several cars, or two horses can fix the distance and struggle at the same time, pulling several cars one after the other.

Li Longji has learned the scientific terminology, which is called changing sliding to rolling and reducing friction.

Li Yi thought about it: "At least you have to earn back the horse's food money, the horse is very hard, don't be tired to death."

If the horse can still work for twenty years, consider the value of the horse and include this money.

The wear and tear of the vehicle, the cost return, is also taken into account.

There is a free line and a half-price line for children, and a weight line and a long and wide line for goods.

Generally, from the west of the city to the east of the city, one person can have one money, and the more people there are, the more money will be earned back. ”

Li Yizai is talking about the fare of the bus, not looking at the age of the child, but looking at the height.

Li Longji understood otherwise, and had questions about the child's half-price: "How to calculate half price for a penny from the west of the city to the east of the city, from the south of the city to the north of the city?" ”

"I've designed a currency below the penny, cents, one, two, five.

Now Jingzhao Mansion is the priority of productivity over demand, and everything is falling in price, don't look at the tax.

When the new rice comes out and the price of rice is lower, I will buy one pound of rice if I want to buy it, and when one pound of rice is less than one dollar, I will use points.

In the absence of over-issuance of currency, Datang's economic development will be better, and the value of the currency will increase.

There is a need for small denominations of money to make up for the gaps and deficiencies in the circulation process. ”

Li Yi was ready, not specifically for the bus.

The exchange coupons of the Li family Zhuangzi have never been overissued, and they are all about how many physical coupons are issued as collateral.

The gold ingots, silver ingots, and copper ingots in the Li family Zhuangzi warehouse were piled up one underground warehouse after another.

Li Yi's actual money is several times more than that of Datang.

But the money didn't belong to him, and he had already issued the currency.

A lot of money is given out on the loan model, like the one that buys clothes, and there are also ships and sleds to make.

Slowly, it will return to its original value, and it will continue to be released in the process of returning to its original cost, but the return period is a little longer.

As with the national debt, the continuous loan profits, or like the banks.

The difference with banks is that a run on the bank is over.

Li Zhuangzi is not afraid, and has enough collateral to exchange all the exchange coupons issued.

Productivity increases, money is not over-issued, and the prices of many commodities are lower.

Li Longji looked at Li Yi, except for nodding, there was nothing else to ask, and when people brought it up, the back hand had already followed.

"Lead, is it enough to cost money?" Li Longji thought about the cost of printing.

"One cent is not enough now, but part of the money of the Li family Zhuangzi is sent out in the form of loans, which can compensate for the cost of printing money."

Li Yi has no direct control over the cost of money, but he can make up for it through gains.

As long as the production technology is good enough and the productive forces of transformation are strong enough, the inflation of money in terms of finance can be suppressed.

Taxes, commodity profits, and interest rates on loans are themselves social activities that drive inflation.

The increase in crop yields and the improvement of the efficiency of handicrafts and the reduction of breeding costs on the same area of land will bring inflation down.

When productivity is high enough, money is not over-issued, and inflation is not as fast as the quantity of goods, it is the moment when the price of goods is reduced.

At this time, it is the time for the people of Datang to enjoy the benefits.

It's not the same thing as deflation where everyone takes money and doesn't buy things, deflation can be troublesome, and once deflation, other means must be taken.

There is no such danger for the time being, so Li Yi will not say it.

When someone joins forces with big capital to make trouble, he will let the other party know how powerful the offensive of currency manipulation is.

He has many ways to trap and let him go, and he will not show mercy at all.
