Here is news from China. A man watches people who travel. These people have heavy luggage. It is difficult to move their luggage. The man has an idea.
He makes a special suitcase. You can ride this suitcase. Its maximum speed is 20 kilometres per hour (12 miles per hour). Its battery lasts six hours. It has a GPS system, too!
The man is happy about his suitcase. He thinks that people will buy it. He says that it will be cheap and easy to carry. It will not make the air dirty like cars do.
Difficult words: luggage (bags which you carry when you travel), suitcase (big bag which you have when you travel), GPS (machine that gives you directions
