An old man in Quanzhou, Fujian, who has spent a decade hitting a rock with his palms, has left a permanent imprint on the rock.

The retired 80-year-old man Hong Qinggen lives near Jinbang Park, and about 10 years ago, began hitting the rock as exercise every day to keep fit. He would hit the rock 1,000 times each day for 2 hours. With years of hitting, the hard rock gradually began showing his two palms.

This exercise as well as other good living habits has apparently kept Hong very healthy for this age.
