It appears to be the X11 forwarding that's failing.  It's authentication of
a sort I guess.

How about .Xauthority?  Is it being written.  If not what permissions does
it have and what permissions does that home directory have?  Make sure the
user can write to /home/jiao/.Xauthority

Looks perfect.

This looks like your problem to me.  Your X authentication fails and you
can't therefore start an X session so all else bombs.
