Changsingdong seems to be very attractive, having such celebrations, due to situation at the foot of the rock that looks like it is a time travel in old time. I bet there are many stories about that rock, to be of such size, we feel ourselves tiny like ants, having no meaning.
The people in the past maybe had the same feeling and wanted to show their love to Buddha when they carved the relief on stone, so that we nowadays also could stun seeing the huge size of rock and Buddha on it.
The steps are something that we people always have to climb, as children we always like to run such steps up competing with others. Also the pictures of that tunnel are impressive, it is a big space created for those who tried to fine a shelter , I hope it was a good place for those people.
Beautiful photo series with nice description :)
