$> man ls
-G Enable colorized output. This option is equivalent to defining
CLICOLOR in the environment. (See below.)
-w Force raw printing of non-printable characters. This is the
default when output is not to a terminal.
If you want terminal can display chinese character and colorized output, you should add a line to ~/.bashrc or ~/.profile or ~/.bash_profile:
alias ls='ls -wG'
alias ll='ls -lawG'
