Literature Reference: Knowing I am of no worldly use, I only love wandering in the mountains. Formerly, I was as lazy as Ji Kang; now I am ashamed to emulate Zhao Wu. Climbing the peaks, I feel no fatigue; floating on water, I forget my worries. I cherish my remaining strength, grasping the vines to explore every hill.
