What do you know about money?
Have you ever wondered where money comes from and how it works? Let’s take a quick look to learn about money!
The start of money
Thousands of years ago, people didn’t use paper or metal money. Instead, they traded useful things — like shells, salt, animals or even big stones — to get what they needed. As trade became more common, people started creating coins and later paper money to make buying and selling easier.
(1)
The first known coins were made around 2,600 years ago in a place called Lydia (now part of Turkey). These coins were made from a mix of gold and silver and helped people trade more easily.
The first paper money in China
China was the first country to use paper money, during the Song dynasty. Merchants (商人) used special notes instead of heavy coins. This made travel and trade much more convenient.
(2)
Today, there are about 180 kinds of currency (货币) around the world. Each one has its own name and value, like the dollar, euro, yen or yuan.
(3)
Many countries put famous people on their coins and banknotes — like kings, writers or leaders. This helps celebrate important figures (人物) and also makes money easier to recognise.
(4)
Modern banknotes have cool features like shiny strips, tiny letters and special pictures. These help stop people from making fake money.
The study of money
The study of how money works is called economics. It helps us understand why things cost what they do and how countries manage money.
