Let me sum up and tell you what it's like to suddenly see a person in the photo.

This feature is only available in computer space. In the navigation bar on the right side of the space, when your friends see the pictures you sent, the system will automatically circle your photos and your own head, and then write, is this XXX? All your friends need to do is click Yes, and you will receive a message saying that you are circled in this photo, and that's it.
