There is an idiom "Handan toddler" that pays too much attention to walking posture, but forgets how to walk. Yan people heard that walking posture, the ancient capital of Handan, was beautiful, so they came to Handan to learn to walk. Failing to do so, I forgot my walking posture, and finally climbed back to Yan State.

I didn't pay attention to the details. Charles III of England lost a horseshoe and a war horse for missing a nail. He lost a war and a country. Charlie is going to fight Richmond. Charlie asked a groom to nail claws on his war horse. The blacksmith missed a nail when nailing the fourth paw, and the blacksmith secretly perfunctory it. Soon, Charlie and the other side got into a fire, and there was a sudden fight in the war.
