caption: The image shows a group of people standing around a table in a room. In the center of the group is a man sitting and holding a pen, signing a document. On the table are books, papers, pens, a telephone, a jar, a glass, a name board, and other objects. To the right of the table is a flower vase on a cupboard, and a photo frame on the wall. The room is decorated with flags, curtains, and glass windows, through which we can see trees and the sky.
