how to show contents tagged under a parent taxonomy term I have contents that can be tagged per taxonomy terms (with hierarchies in content type), say, 
Events > weddings
Events > birthdays
Events > public > national day celebration

The events (which is a vocab) actually turns into a menu (using taxonomy menus) and I want it so that when users click 'Events' menu all contents tagged weddings, tagged birthdays, tagged national day celebrations will show up on the page.

This content type (Events) has a field called 'Type' which is a hierarchical taxonomy list from the vocab 'events'. I had it set so that the term lineage will be save in the hierarchical select settings, I was under the impression that for any content tagged 'weddings' for example, this same content will also be tagged as 'events' by the system due to 'save term lineage' settings...

When I go to http://mysite/events (which i already configured using pathauto, and used views to display taxonomy terms related to nodes) none show up, as if none is being tagged 'events' at all. But when going http://mysite/weddings i get all contents tagged under weddings only (which is right). 

Thanks!

EDIT: This content type (Events) has field called 'Type' which is NOT a hierarchical taxonomy list but a select list. Sorry for that.
I believe you may need to have the content tagged in both terms,  "Events" and "Type" for this to work without custom coding. 

You can get this through a view or custom module quite easily, though. If no answers posted later on, I will post you an update when I get home as I am writing this from mobile.

Good-luck
