Optimus Prime

　　Optimus Prime is located below Heilongtan, at an altitude of 1,500 meters. On a flat slope rises a stone that thrusts straight into the clouds, resembling a giant pillar supporting the sky — hence the name “Optimus Prime.” Walking to the lower right, the stone seems to be on the verge of toppling. The shaded side of the massive pillar is draped with green trees and vines, hanging and swaying in disorder.
