How is the information written by Xiaomi's mobile phone stored in the draft?

I also encountered this problem some time ago. Xiaomi has no separate draft box. If contacts have been added to the edited information, you can save the draft when you exit (for example, returning directly after entering a short message will automatically save the draft in your information, just like where you usually read the information sent by others, you can display the word "draft" in green). If you don't add a contact, you will be asked if you can quit without saving the draft.
