While the connection
between other hosts(also in my network) can not show all information, such
as src_bytes and dst_bytes, instead of number it show "?".

The key for those connections is their status. In this case, it is S0:

1041604588.107852 ? ftp ? ? S0 X
                 ~~~ ~~~~~


which (as explained in doc/conn-logs) means "no answer". Because there
was no answer, the connection does not have a meaningful duration, or
volume of bytes sent in either direction.
