It may be that the rocks of the emperors are not rocks but parts of stoned ancient trees... well at least they didn't paint faces on their rocks... they admired the strangeness of nature itself. Today people try to personalize the rocks. To make them look like humans... our ego on the stones... not even leaving a mark on a permanent rock in nature... No no no.... they will keep them at houses...
Man... we are lost... :)
Ancient trees used to get stoned? Really? :-)
The Emperors would move gigantic rocks for a thousand kilometers to balance the "feng shui" of a formal garden.
