Okay kiddo, so you know how we have rules at home and in school that we have to follow? Well, a place called Hong Kong also has rules that people have to follow. But sometimes, the people in charge of making the rules, called the government, don't want people to say or do certain things that they don't like. This is called censorship.
Now, in Hong Kong, there are some people who want to say things or share ideas that are different from what the government wants them to say. But the government doesn't want these ideas to spread, so they use censorship to stop people from talking about them.
One example of this is the recent protests in Hong Kong. Some people who joined the protests wanted to say things that the government didn't like, such as criticizing the way the government is running things. So, the government tried to censor these ideas by blocking websites and deleting posts on social media that were related to the protests.
This can be a problem, because it means that people can't share their ideas freely and openly. It can also make it harder for people to know what is really happening in their country if the government controls what information is available.
So, censorship in Hong Kong can make it difficult for people to express themselves or know what's going on. But, there are still many people who are fighting for their right to free speech and trying to make sure that censorship doesn't stop them from sharing their ideas.
