Gif: How can I send private messages to others faster?

If the person you want to send a private message sends a video, you can click on the video, and then click on her avatar, and her interface will appear. Then there is a pen in the upper right corner to write on a piece of paper. You can send a private message with one click. If the person you want to send a private message doesn't send a video, you can powder him and find him in the attention. Click on it and his interface will appear. Steps are the same as above.
