Radio jamming is like playing with a toy that makes noise and you don't want to hear it. Imagine you are listening to your favorite song on the radio, and suddenly, someone starts making loud and strange noises. This would make you feel upset and annoyed because you can't listen to your song anymore.
In China, the government uses radio jamming to stop people from listening to some radio stations they don't approve of. They do this by using special devices that create sounds that interfere with the radio signals. It's like when you try to talk to your friend in a noisy classroom, it's hard to hear each other because of all the background noise.
The Chinese government thinks that some radio stations can cause problems or share information they don't want people to hear. They want to control what information people get access to, but some people think that it's not fair because they have the right to listen to whatever they want.
Just like when someone takes away your toy that makes noise, radio jamming takes away the ability of people to listen to what they want. It's a complicated topic, but the most important thing to remember is that everyone should have the right to choose what they listen to.
