The image is a photograph of three pieces of brush writing on a piece of paper. The paper is brown in color and has Chinese characters written on it. The text on the paper is written in black ink and appears to be a description of the brush writing. 

The first piece on the left is a rectangular piece of wood with a rough texture. It has a small indentation in the center, which could be a mark or a mark of some kind. The second piece in the middle is a larger piece of stone with a pointed tip. The third piece is a smaller piece with a flat base and a curved top. It is also made of wood and has a rough, uneven surface.

There are also two smaller pieces on the right side of the paper, which appear to be the same shape and size. The larger piece is slightly larger than the smaller one on the bottom and is slightly smaller than the larger one. Both pieces have small holes or indentations on the surface, which may be used for writing or drawing. The image appears to have been taken in a museum or exhibition space.
