It's ok to simply use the light and shadow magician and Meitu Xiu Xiu, and the drawing that comes with the computer is also ok. PS is too overqualified.
An avatar you like, you can download it or take a selfie.
Start making:
1. Demonstrated by a light and shadow magician. Other software has the same principle. Open the magic hand of light and shadow, click Open, find the prepared avatar file, and click Open.
2. Click the brush button in the upper right corner.
3. Click the circle on the brush tool on the right, as shown below. Then hold down the Shift key and drag a circle on the avatar, and move it to the upper right corner to align the boundary. Tip: Use the up, down, left and right arrow keys to move the image more accurately.
4. Click on the text, then enter the number 1 in the input box below, click "b" to make it bold, and then drag the number in the avatar to the middle of the red circle. The font size is up to you.
5. You are finished! Obsessive-compulsive disorder avatar perfect release!
Meitu Xiu Xiu, Drawing and other softwares have the same principle, and they all draw a circle with red filling color, without borders, plus a white number 1.
I hope to adopt.
