Then long press Copy All, then open WeChat and delete the original nickname in the nickname setting interface of WeChat.
Just press Paste and you can save it. Some mobile phones can't be saved, so you need to use other methods to get blank messages.
We can also get some blank messages by other methods. For example, we can use WeChat to generate it on the computer. Different input methods have different methods.
For example, the sogou input method can be generated by inputting v1d.
Send it to our mobile phone after it is generated. The specific operation is the same as above.
