Old Chuan and his wife, the proprietors of a small tea shop, save their money to buy a folk medicine cure for their son, Young Chuan, who is dying of tuberculosis. The story opens with Old Chuan leaving their shop and going to the home of the person selling the cure, a "roll of steamed bread, from which crimson drops were dripping to the ground." The crimson drops, we soon learn, are blood from a young man recently executed, apparently for revolutionary activities.
The cure does not work and the mother of Young Chuan meets the mother of the executed revolutionary in the cemetery. Here they both behold a mysterious wreath on the revolutionary's grave, a wreath that Lu Hsun, in his introduction to this collection (which he entitled A Call to Arms), describes as one of his "innuendoes" to "those fighters who are galloping on in loneliness, so that they do not lose heart." (p. 5)
