A Poet named Shi lived in a stone house and liked to eat lion flesh, and he vowed to eat ten of them. He used to go to the market in search of lions, and one day at ten o’clock, he chanced to see ten of them there. Shi killed the lions with arrows and picked up their bodies, carrying them back to his stone house. His house was dripping with water so he requested that his servants proceed to dry it. Then he began to try to eat the bodies of the ten lions. It was only then he realised that these were in fact ten lions made of stone. Try to explain the riddle.
