Three Linux Chinese support
As a prerequisite, correctly install Chinese fonts and Chinese language system.
If there is a graphical interface, it can correctly support Chinese display.
If you use a third-party remote attack, as long as the language system is set correctly, it can support Chinese display
If you use a pure character interface, you must use a third-party plugin (such as zhcon, etc.)
