1. Enter Baidu Post Bar-Login User Name

2. Move the mouse to "My I Post Bar"-select "View All" in the drop-down menu-click "Signature File Settings"

3. Click "Edit" after signing the file to modify the name and picture link of the signed file in the pop-up dialog box. Click "Submit" to edit successfully.

Note: The signature file only supports the pictures in Baidu Post Bar Picture Library and Baidu Space. You can upload the picture to my space first.

4. If you want to add a set of signature files, you can click "Add a set of signature files" to see the pop-up signature file editing page.

Note: Baidu can set up up to five sets of signature files.

5. Enter the name of the signature file you want in the name input box, and enter the picture link in the picture link bar to see the picture you selected in the picture preview. Click Submit, and the signature file is submitted successfully.

6. The signature file just submitted may take some time to review. Please wait patiently ~ ~ After the review is completed, you can use the new signature file when posting!

7. The premise of using the signature file is that users who have registered for more than three months can use it.

Your Baidu account has not been registered for three months, so you can't get it now. After waiting for three months, maybe I can help you.
