A full container load is when you have a really big box called a container and you fill it up with lots of things. It's like when you clean up your toys and put them all in your toy box! But this box is much bigger than your toy box - it can be as big as a truck or even a train!
When grown-ups want to send lots of things from one place to another, they can use a full container load. This way, everything stays together and safe. Just like how you keep all your toys in one place so you don't lose any.
Sometimes, people don't have enough things to fill up a whole container, so they share it with other people. It's like sharing your toy box with your friends. This is called a less than container load.
When the container is full of things, it gets put on a big ship or a train to travel to its destination. It can even be loaded onto a truck to travel shorter distances.
So, when grown-ups want to send lots and lots of things, they use a full container load, which is like a really big toy box filled with lots of things that gets sent on a big ship or train!
