Exchange cookies
Look at the cookie of the URL from an IE browser, find it and exchange cookie with a person.
Delete the cookie in the IE browser, and then import someone else's cookie from the browser. Remember to click "automatic login within ten days" when logging in to your own account.
Select the import and export options from the file options in the browser, and follow the steps to import the exchanged cookie. Finally, if the import is successful, you will directly enter the management background of the other party's blog.
