First, the WeChat name cannot be set to blank now. If it is set to blank, it will not be saved. In the past, WeChat did not have real-name authentication and did not have so many strict requirements. It may be possible, but it is not possible now.

2. The steps to set the WeChat name are as follows:

1. Open WeChat and click on the area shown in the picture below;

2. Find the name in the profile editor column, click;

3. Enter the WeChat name that needs to be set in the box (it cannot be blank, it cannot contain symbols and emoticons that WeChat does not support, otherwise it will not be modified), and click the upper right corner after the input is successful. That's it.
