Ding-ding sends a message. Why must the opposite side see it?

Send a message directly to the person in the nail, and the other person can see it.

Send a message directly to the person in the nail, and the other person can see it. As long as you are in the same structure as this person, you can send messages directly. If you send a message to the other party here, you can see a sign indicating that you have read it, but sometimes a message box will pop up if you send a message to the other party. Even if you don't read it, you will see the email, but it will show unread.

Ding is an original function, which can convert short messages into phone calls/short messages and send them to others. No matter how busy the other party is, just click and the other party will reply to your message immediately.
