The use of Cydia is actually not complicated. Software installed through Cydia only needs to be deleted in Cydia.

1. Enter Cydia and click “Manage”.

　2. After clicking on the software to be deleted, you will come to the interface below, click "Modify" in the upper right corner.

　3. Go to the interface below, click "Remove" to remove the program delete. In the same way as the installation, depending on the different functions of the uninstalled deb program, there will be three different situations: Reboot Device (Reboot Device), log out and restart the desktop (Respring), and return to Cydia. Follow the Cydia prompts.

In addition, you can also delete the software by connecting to the mobile assistant.
