Okay kiddo, so Aisin Gioro is a special family that used to be really important in ruling China a long time ago. They were called the imperial family because they were like kings and queens.
Their family name is Aisin Gioro, which is kind of like having a last name like Smith or Johnson. They were in charge of a big group of people called the Qing Dynasty, and they were in charge of everything that happened in China!
But now, they don't have that power anymore because China has a different way of running things. Even though they don't have that power, they are still around and people still know their name.
