Hello, the prerequisite for setting the signature file is to register Baidu users for 3 months (90 days).

Steps:

1. Enter my I Post Bar.

2. Click Personal Settings on the right.

3. After entering, you can see that there is a signature file setting. ..

4. Then add a set of signature files for use (5 sets can be set in total * * *).

In addition, the size of the signature file is limited, with a maximum width of 500 pixels and a height of 200 pixels.

If the picture you make is too big, Baidu will automatically reduce it to the right size for you.

It usually takes three months and needs to be audited.
