Alright little one, let me explain what autonomous administration of North and East Syria means.
You know how you have your own room in your house and you can decorate it and keep your things in it however you like? Well, the people in North and East Syria wanted to have more say in how their land was run too, so they came up with a plan for autonomous administration.
This means that the people who live in that area get to make decisions for themselves about things like healthcare, education, and local laws. They have their own government that is separate from the rest of Syria.
But it's not just one person making all the decisions, they work together as a group called a council. The council is made up of people from different communities and backgrounds, so everyone's voice is heard.
One of the really cool things about this system is that they try to make sure women and people from different ethnic groups have an equal say in decision making.
So, in short, the autonomous administration of North and East Syria is a way for the people who live in that area to make decisions for themselves, work together as a council, and make sure everyone's voice is heard.
