Operating environment:
After installing Debian, the folders in the home directory are displayed in Chinese in a Chinese environment, which is inconvenient for using the cd command. The software xdg-user-dirs-gtk (already installed by default in the Gnome environment) can be used to easily change them to English.
The next time you enter the system, you will be prompted whether to convert the directories to Chinese. Choose "No" and select "Do not ask again", then cancel the modification.
