I always run with -x (options -> build -> no external pages=checked) so you
know where the mirror stops

All links on that page are in the form: href
<http://www.aiki-viet.com.vn/plonePrint.css>
All absolute and all starting with www.
Httrack does not by default go off site, so you got nothing.
Mirror www.aiki-viet.com.vn instead.
