Arrow, Counterclockwise
This is an anti-clockwise rotating arrow, which is depicted in a blue or gray box on most platforms. There are two arrows, one above and one below, which rotate to the left and right respectively. They are connected end to end and are in a counterclockwise circulation.
The colors of arrows vary from platform to platform, and are mainly divided into three colors: black, white and gray. The lines depicting arrows have different thickness on different platforms. The lines on OpenMoji and Microsoft platforms are relatively thin, while the lines on Messenger platform are relatively thick.
This expression is commonly used to mean circulation and counterclockwise rotation.
