How to press the line feed key when sending messages on Apple's mobile phone?

Just click "Line Feed" in the lower right corner of Apple's mobile phone to send a message.

Click "Line Break" in the lower right corner; However, in some third-party softwares such as WeChat and QQ, it is impossible to feed lines directly by using the input method, and there is only the send key on the keyboard.

Take WeChat as an example, chat with a friend, and then click on the text input box. When you want to wrap a line, press and hold the "Enter icon" for about two seconds, and a prompt will appear. There is a line break option on it. You can choose a line break.

Use the voice input function of the keyboard, open the keyboard, click the "microphone" icon in the lower right corner, and then say "line feed" or "next line".
