What does WeChat avatar little red dot mean?

This is an "obsessive-compulsive portrait", similar to an image with unread messages. Obsessive-compulsive disorder patients are used to clicking on every message, but this kind of picture will make obsessive-compulsive disorder patients infinitely entangled.

How to make it: Open a picture, draw a circle with strokes in the upper right corner, or draw a circle with graphic tools, and master the position and size by yourself, and then add a number to the center of the circle with text tools to master the position and size by yourself.
