Thank you, I thought it is related with this issue, so just ask here,
next time, I will do my research first.

I think I found the cause of my problem, it turns out I am using an
very old /etc/profile. I move the /etc/profile to /etc/profile.bak and
reinstall the filesystem package, then I diff the /etc/profile and
/etc/profile.bak. I found my previous version of /etc/profile using
the some sort of guess mechanism to find the shell that is using and
'sh' is the default value of $SHELL which may cause the last line of
'source /etc/bash-completion' running in compatibility mode.

Here is the diff output.
