I believe that, after you lose QQ, your friends cannot find it, and your chat records have been carefully studied several times after QQ is lost, the list and records can be recovered.
Method 1:
1. List Restoration
First, find the user. DB file in your QQ directory (If your QQ number is 12345, it will be in the 12345 folder). This is your friend list. Copy it and log on to your new QQ application. You can chat with a netizen. Otherwise, it will not succeed. Next, close QQ, open your new QQ number folder, replace the copied user. dB with your new user. DB, then log on to your new QQ, and the friends list is back.
2. Chat record recovery
First, close QQ, find the folder of your original QQ number, find a file named msg. DB, copy it to the folder of your newly applied QQ, and overwrite the original msg. DB. Then Open QQ and enter your new QQ number. Then a dialog box is displayed, asking you to enter the local message number. It doesn't matter. You just need to enter your original QQ number. Go to QQ, pull your friends out of strangers, and your QQ friends will be out, of course, there are chat records
Method 2: I think it is very useful.
1. Retrieve the friends list: You can find them in your QQ mailbox. All QQ friends are in it.
2 chat record retrieval: after finding the QQ friend's QQ number in the QQ mailbox, directly enter the QQ number and blacklist it to view the chat record.
