The image is a colorful mural on the side of a building. The mural is made up of various elements, including a large pink circle with a rainbow and an octopus on it. Inside the circle, there are two cartoon characters, a boy and a girl, sitting on top of a rainbow. The boy is wearing a blue cap and a green shirt, and the girl is holding a blue umbrella. They are both smiling and appear to be having fun.

On the left side of the mural, there is a pink cloud with Chinese characters written on it, which translates to "Happy Birthday" in English. On the right side, the word "Happy" is written in red and blue letters. The background is a gray tiled wall with a red door and a sign that reads "Exit".
