Every day we use money to buy what we want. But have you ever really noticed the bill (钞票) in your hand? There are different pictures on both sides of banknotes (纸币) and interesting stories behind them.

Most banknotes have famous people on the front, such as a country’s leader or a great scientist, while on the back of the paper note there are usually some well-known scenes or national buildings.

The latest editions of Chinese banknotes use the picture of Mao Zedong, founding father of the People’s Republic of China, on the front of all yuan bills. However, the backs of the bills are different. The Great Hall of the People, on the 100-yuan note, is a landmark (地标) in Beijing. Important meetings are always held there. The Lijiang River in Guilin, on the 20-yuan note, is one of the most beautiful scenes in the world.

The US 1-dollar bill has the first president, George Washington, on the front side. A 13-level pyramid is on the back.
