Check the login account: the chat records of different accounts are definitely different, because they are logged in with the mobile phone number, so check the account to see if the account you want to inquire is this number.
Open the chat box on the right: after login, we can find the chat box on the right. As long as it is not deleted, the previous chat records will be here. Click to view it.
Click the user to view: in the dialog box, there are different users. You need to look at their chat records. Just click on their heads and you can pull them out. Historical chat history exists.
If you don't match, the chat record will be deleted automatically: if you have successfully matched this person before and chatted with him, and now you have contacted and matched her, then she will disappear from the matching list, and the chat record will naturally disappear.
You can't query the deleted: another case is that you didn't unbind, but the chat record was deliberately deleted, so you can't find it, but this person is still in the matching list, so you can chat again.
