I dated online. I can't even answer his phone (it sounds like Cai Ling's). He sent another short message saying that I was in a meeting.

Hello, this is the automatic reply function of mobile phone. Collectively referred to as driving mode. After you dial the number, there will be a bell for a second or two, followed by a voice that is on the phone or can't be answered. When your call is interrupted, his mobile phone will automatically reply to you with a message. The content of the message can be the content of the mobile phone itself, or it can be the content that you set up to edit yourself before. The other party's mobile phone will also display missed calls, so don't think too much, just wait for him to reply.
