So, you know how sometimes people disagree with each other about things? Well, in Hong Kong, a place in a country called China, some people are very upset about a new law that their government wants to make. This law would allow people who do bad things to be sent to a different place to be punished, even if they didn't do anything wrong in that place.
Some people in Hong Kong think this law is not fair and would make it easier for China to control Hong Kong. They want to keep their own rules and have more say in how things are done. So, they started talking about how they felt and going to the streets to show their disagreement.
As more and more people joined in, it became a big protest. The protesters want their government to listen to them and change the law. The police and government have tried to stop the protest, but the protesters keep going out to show how they feel.
It's important to remember that everyone should be able to say what they think is right and be listened to, even if other people don't agree with them. It's called freedom of speech.
