I have been to Dazu Rock Carvings.
it is not easy to go there even in nowadays,we can not imagine how difficult it is for our ancient to went there and did something.
I really have to say it is worth to go to this far away carvings--it has a beautiful hell seclpture and a grand six reincarnation sculpture.
there are majestic sences in the mountains.
I believe this is the best area that I have been in Chongqing.
