What does sand painting mean?

Sand painting is not painted with pen and ink, but with colored sand.

The background of sand painting is self-adhesive paper, and a painting is carved on the backing paper of self-adhesive paper with a numerical control machine or a carving machine. When painting, uncover the backing paper of the self-adhesive step by step, evenly remove the colored sand of the selected color from the self-adhesive at each step, and then clean up the excess sand, and finally get a colored sand painting. For children, it is a hand-made picture with color arrangement and collocation. It's actually more like a jigsaw puzzle.

Extended data

Sand painting is an ancient and traditional artistic expression, which can be traced back to a special picture symbol that was born for communication and notes before the appearance of human language. From the historical origin, this kind of image symbol develops in two directions: one is the direction of writing language, which forms our language and writing system today;

The first is the direction of painting art, forming a variety of painting art forms. There were allusions of "Sha Shu changed into characters" and "Sha Shu changed into paintings" in China during the Song Dynasty, but in Vanuatu, which is located in Melanesia Islands in the southwest Pacific Ocean, this artistic heritage with multiple functions such as ceremony, meditation and communication is still preserved.
