Is there a waiting port behind WeChat? There is a bell and a horizontal symbol under the sky, sometimes not.

That's the message don't disturb mode, and the message don't disturb is set, so that there will be no bell prompt when there is a message, but you can watch it when you click on it, which will not affect the chat, and it will be gone once you pass.

There is no ringtone in the WeChat group by default. At this time, when someone chats in the group, there will be a prompt. However, if the group is set to "Do Not Disturb", a ringtone with a diagonal line will appear.
