What he said has always influenced me. Until now, I have never made a wrong choice.
The importance of choice can be reflected in all aspects of life. Everyone has heard the story that you can't have your cake and eat it. If it were you, what would you choose?
In fact, it doesn't matter which one you choose, the key is to choose the right one.
Someone once asked me, which should I choose, one hundred tons and one hundred tons? The answer I gave him at that time was yes.
China's currency development has a history of 4000 years, and it has been constantly changing in this process.
0 1 barter
In the earliest times, people needed things and had to exchange them with things. At that time, people used stones, shells, feathers, etc., among which shells were the most important items.
02 metal currency
The earliest metal currency in China was produced in Shang Dynasty, and its name was Tongbei. At that time, the bronze smelting technology of Shang Dynasty tended to be perfect, and people thought it was possible to make bronzes and copper coins. Since then, the copper shell came into being.
Why is it called Tongbei? In fact, the image of copper coins made is like shell coins, so it is called copper shell. Until the middle of the Spring and Autumn Period, the copper shell was improved and plated with a layer of gold, which looked more gorgeous.
paper money
With the continuous development of economy, it is more and more inconvenient to use metal currency, especially in some large transactions. Secondly, metal currency is easy to wear and tear. Once the wear is serious, the loss is great.
Then came the world's earliest paper money, the cross of the Song Dynasty.
Put aside the evolution of money and go back to the original choice question.
Although it looks simple, it is difficult for anyone to do it right. Most people should choose large bills, but we can't just consider the large amount and ignore the tonnage problem. A hundred tons is a hundred times as much as a ton. So how to choose this question, let's calculate it carefully next.
The calculation of paper money is based on the latest set of RMB. A hundred-dollar bill weighs 1. 15g, and a one-dollar bill weighs 0.74g ..
A ton of paper money with a face value of 100 yuan is about 87 million yuan; One hundred tons of one-dollar bills is about 6.5438+35 million yuan. If you don't allow the number, there must be many people who choose large denominations.
Of course, the choice of these two depends on the situation. If you don't have enough time and space, you can only choose this one-ton one hundred yuan; If you have time and space, that is, you need more money, then you can choose one hundred tons for one yuan. Although the face value is small, it is heavy and large.
As far as mathematics is concerned, this is a very simple topic, but it is difficult to do it right under the logic of common sense.
Of course, no matter what the topic is, it is a piece of cake for human beings, and human wisdom is infinite.
