China brain

Hey there kiddo, have you ever heard of the term "China brain"? Well, it's actually a big term used to describe something called collective intelligence.

Now, just like how we humans have a brain inside our heads that helps us think, communicate and learn new things, the term "China brain" refers to a group of people who work together to solve problems, make decisions, and come up with new ideas.

In other words, it's a large group of people who put their heads together to work as one in order to achieve something big. And just like how a person's brain can think and communicate with other parts of their body, the China brain can combine the knowledge and abilities of all these people to come up with amazing solutions and ideas.

So imagine, if you and all your friends work together to solve a problem, you would be like a China brain!
