caption: The image shows a stairwell with red walls and a clock on the wall. At the bottom of the stairs, there is a railing and a mat on the floor. On the right side of the image, there are books arranged in a rack. In the middle of the picture, there appears to be a table with a flower vase and some papers on it. There are two stools and a table in front of the table, and two windows on the left side. On both sides of the windows, we can see the trees outside.
