1. After logging into the platform, there is a gear button on the upper right, which is used for setting. Click it and select Personal Center. 2. Select the avatar setting in the column on the left. 3. You can upload pictures locally or take pictures first. I choose local upload here. 4. After finding the picture, click Open, and then click Save. 5. In this way, the effects of large, medium and small avatars are displayed. 6. Open your own work or study space and see that the outside of the avatar is in a circular outline, so that the avatar is set.
