Okay, so imagine you want to send a toy to your friend who lives far away. You can either take it to them yourself or you can ask someone else to do it for you.
Now imagine that instead of just toys, there are big, heavy things like food, clothes, and even cars that need to be sent all over the world. The people who are in charge of sending these things are called shippers.
In Greece, there are a lot of people who are really good at shipping things all over the world. They have big ships that can carry a lot of stuff at once. These ships have to be really strong and sturdy because they have to be able to travel across big oceans and withstand the weather.
The people who own these big ships and the companies they work for are called Greek shipping companies. They are very important because they help get things from one place to another, like when you want to send a toy to your friend.
Some of the things that Greek shipping companies send are really important, like medicine or food. They also send things that people buy online, like clothes or electronics.
So basically, Greek shipping is when people in Greece use big, strong ships to send things all over the world.
