When did the postal delivery receive the text message?

The post office sends a courier, but the other party can't receive the message. If the postal express has just been sent out, there is no news from the recipient. If the recipient pays attention to the official account of the postal WeChat WeChat, or downloads his applet, maybe the postal service is in the WeChat app and. There will be news in his applet, but if the other party doesn't download it, you won't see the progress of the express delivery you sent.
