Okay, let me explain it to you like you're five years old.
So you know how there are some people who go to space in rockets? Well, these people are called astronauts. Now, there are some people from a country called China who are also astronauts. But, the special thing about these astronauts is that they are all girls, or women.
This means that the country of China is taking big steps to show that girls can do anything that boys can do, even go to space! It's really cool because it shows that everyone, no matter what their gender is, can explore and learn about space.
