Breadcrumbs how do reflect the hierarchy？

give advanced_menu (handles breadcrumbs from admin side) a shot in the modules directory. It should eliminate some if not all of the confusion.

Breadcrumbs work reasonably well in some situations, like on the admin side or when using modules which have a lot of hierarchy in their functionality (like the gallery function in image.module or forums in forum.module). However, the nature of Drupal is to use 'nodes' for content whenever possible. The downside of this approach is there is no hierarchy at all in the management of this content. The breadcrumb for any node will always be "Home", and that's it. To help your users navigate through a complex website, you'll likely want to set the breadcrumbs yourself. Check out drupal_get_breadcrumb and drupal_set_breadcrumb for details.
