The image shows a display case with a collection of ancient artifacts. There are nine pieces of stone arranged in a grid-like pattern on the display case. The stones appear to be of different sizes and shapes, with some having a rough texture and others having a smooth surface. Some of the stones have small holes or indentations on them, while others have a more rounded shape. There is also a small triangular shape on the right side of the display. On the top right corner of the image, there is a yellow sign with black text that reads "Cảnh đồng đàn lạo dầu đước bội đám mặt rửa mùi mài 2" which translates to "Tools: Polishing axes (2)". Below the sign, there are two small yellow triangles, one of which is likely a reference to the tools used in polishing the stones.
