Okay kiddo, so in Hong Kong some people want to have a say in how their government works, and they believe that everyone should have the chance to vote and choose the leaders of the city. These people are known as the pro-democracy camp.
You see, in Hong Kong there are two main groups of people - those who want more freedom and democracy, and those who are happy with the way things are and want to stay close to China. The pro-democracy camp believes that it's important for people to have a voice in their own future, so they organize and speak up for their beliefs.
Now, some people in Hong Kong and China don't like the pro-democracy camp because they think that it could make Hong Kong more independent from China. They want to keep control over the city, and they don't want to give people too much power. So, the pro-democracy camp has to be very careful about how they campaign and protest, because they could be punished for opposing the Chinese government.
Overall, the pro-democracy camp just wants to make sure that everyone in Hong Kong has a fair say in how they are governed, and they will keep fighting for their beliefs no matter how hard it gets.
