The image is a digital poster with a blue background and white text. On the left side of the poster, there is a cartoon illustration of a girl with green hair and a blue dress, holding a yellow cup in her hand. She has a big smile on her face and is standing in front of a computer screen with a group of anime characters on it. 

On the right side, there are two girls with pink hair, one with red hair and the other with blue hair. They are both wearing school uniforms and are standing next to each other.

At the top of the screen, there appears to be a chat window with a message in Chinese that reads "ACG" and a QR code below it. There are also two red crosses on either side of this text, indicating that the poster is promoting the ACG app.
