Wechat hacked a person, and he sent me a text message saying that the chat records were all backed up because I lied to him on WeChat. What will happen to me?

If you hacked someone on WeChat, but he backed up your related chat records, it means that the transaction between you and the previous chat process are still in his mobile phone. It can be seen that under this premise, even if you have hacked him or uninstalled WeChat, if the record is still there, you can't escape this connection.
