Balancing on a chair using only one arm is tricky, but imagine doing it on the edge of a cliff!
Extreme balancing artist Eskil Ronningsbakken completed an acrobatic performance on a stage at the edge of Mountain Tai in East China.
His tricks included doing ballet moves in the air, as well as swinging on a trapeze without a safety net.
Eskil admitted he was nervous at first but once he'd finished, he said: "It felt good, it was going the right way."
For his final trick the daredevil stacked three wooden chairs one on top of another before doing a handstand.
Don't try this at home!
