The image shows a wooden door with Chinese characters written on it. The door appears to be in a room with a white wall and a wooden floor. On the left side of the door, there is a sign with the letters "A" and "B" written in black, and on the right side, there are two signs with red and white text. The sign on the top left reads "No. 2179" and the sign in the middle reads "1-8" with a red arrow pointing to the right. The text on the bottom right reads "3".
