Why does money have a size, and how much does money work? What is life for?

In the vernacular, a Chinese man sells for 7 yuan, and the United States sells for 1 yuan. Then 7 1 is the exchange rate [your RMB above is about 7 against the US dollar; 1 is not 1; 7, now it seems to be 6; 1 That's it].

In fact, the exchange rate is a measure of the level of social productivity of two countries. It takes 7 hours for our country to build a Han Satie, and the United States has a high productivity, so it only takes 1 hour.

Of course, it is not accurate to measure it by a single man, and it needs to be measured as a whole of all commodities and labor.

China's price index The price index of the United States = the exchange rate between China and the United States [that is 1:7] Of course, the exchange rate is not as simple as I said, and the above is to help you understand. But rightly.

If you don't understand, continue to communicate.

For example, in ancient times, when things were changed, a few chickens could be exchanged for a sheep.

Behind the coins is a symbol of the country's economic strength, that is, the gold content of the coins is different.

Previously, coins were pegged to **.

In recent years, China's national strength has been rising, but it has also issued too many renminbi and printed too much banknotes, which has led to the rise of goods, which is inflation.

Internationally, too, there is a crisis in Zimbabwe, there is a problem with the payment of currency (to the country, while foreign exchange is to the country of another country), and there is a currency with a face value of 100 million yuan, but it can only buy very little things.

So the problem behind it is the problem of national credibility and strength, the world economic crisis, relatively speaking, the United States is built on a free and equal system, and the election of ** can achieve democratic elections (although the election costs a lot of money, it is worth it relative to the armed war), so the country's political situation is stable, science and technology are developed, and the economy will be better sooner or later, so the dollar**.

And some other countries in the world are difficult to say, so there is a general devaluation.

It is the comparison of the strength of various countries!

The reason why money can perform the function of a value measure is that money itself has value. The amount of labor condensed in a commodity is an intrinsic measure of the value of a commodity. However, the quantity of value of a commodity cannot be expressed directly in terms of labour time, but only indirectly in the process of exchange by the amount of money equal to it.

Learning a car ** is generally around 5000, and the cheap ones are more than 4000, but there are other expenses along the way.

The role of money is understandably great, basically there is a need can be obtained with money, but I think life is not just for money, money is just a tool, life is to you according to your own ideas, try your best to live happily and hopefully.

Wii is divided into two types: hard disk version and disc version, the hard disk version of Wii can only be played with mobile hard disks, and the standard hard disk version (a pair of handles, a host, various cables, etc.) is about 1200. Note this** is not with a hard disk, the hard disk needs to be bought by yourself, you can choose 250g or 32g or 500g mobile hard disk, you need to add additional money.

Each place is not the same, and now many of them are Korean consoles, and most of the accessories for you are imitations.

The minimum is about 60 liters, and most of this kind is only refrigerated, and you can buy it for five or six hundred yuan. The larger one is about 118 liters, this kind of frozen (29 liters), refrigerated (89 liters) are available, about 1,002 yuan, if it is not a lot of ice, I think this is not bad, both functions are available.
