Apparently taken in China of a man rendering the top of a multi storey building from what is effectively a suspended plank. The man has created an ingenious contraption with ropes and wood cross bars supporting the plank, but the chances of falling of, or the whole thing failing are exceptionally high. In spite of this he is confident enough to have his large bucket of mortar with him on the plank! Hopefully he made it to the end without incident.
The trouble is that he will then use it again and again until he is not quite as lucky.
