When I run:

xterm

The following text is shown:

Warning: This program is an suid-root program or is being run by the root user.
The full text of the error or warning message cannot be safely formatted
in this environment. You may get a more descriptive message by running the
program as a non-root user or by removing the suid bit on the executable.
xterm: Xt error: Can't open display: %s
xterm: DISPLAY is not set`

I don't know what the problem is. Would you help to slove this issue?

You're not running xterm under a GUI. GUIs (The X Window system, Wayland, ...) set the DISPLAY environment variable to point to the active display. In a text terminal DISPLAY isn't set, there's no GUI, and xterm won't work.
