First of all, we should open our WeChat and find the personal information interface.
Click on the "Name" column in the personal information to enter the modification. The first method is to add icons directly, and click the "Emoji" of the mobile phone input method to add them directly.
Another way is to input an icon, such as "smiley face" Lian Xiao, and then you can see this expression in the input method below.
Finally, click Save in the upper right corner to complete the modification of the small icon of WeChat name.
