Cao Cao wanted to weigh it but he didn’t know how. His officers didn’t know how to weigh it either. Cao Chong, Cao Cao’s son, had an idea. He put the elephant into a boat. He made a mark of the water on the boat with a knife. Then he put stones into the boat. He stopped when the water got to the mark. At last, he weighed all the stones and got the weight of the elephant. What do you learn from the story? We should think more when we meet difficulties. “ ” “ ”
