As the operator of the hotline 12345, generally speaking, the recovery method is like this. First of all, when you connect the phone, say hello to the other party and ask what you need. Then, after the other person has finished speaking, you reply to him like this. You said that I memorized everything you said, so I'll contact the relevant departments immediately to solve it. Please keep your mobile phone on so that you can answer the corresponding call. Thank you for your support of our work.
