You can't delete nicknames and avatars in the same city unless you cancel your account. However, you can change your avatar and nickname in the following ways:

1. First, we enter 58 cities in the browser and click on Baidu's No.1 58 city website. Click to enter.

2. After logging in to the website, find the personal center at the top of the website and click.

3. Click Personal Center, find my account in the drop-down menu, and then click.

4. There is a function of uploading pictures by individuals in the introduction, and users can choose their favorite avatars.

Nicknames are similar to avatars. You can try them yourself.
