Cms, Label and Tags ( Page=

Can you please help me, I have been trying to figure out how to sort my posts.
I have an article about an exhibition, this is in my collection- exhibition.
This exhibition article is also about sculpture, painting and photography. How can I create labels that direct me to exhibitions with the subject sculpture?

How do I link these posts to other pages? Is there a tutorial somewhere that I am overlooking?.

OR do I have to create a page where all my sorted contend go?

Here is my public share link: LINK
