Hot air, grave, three idle episodes, two-hearted episodes, Gai Hua episodes, justice episodes, South-to-North mobilization, and street pavilion sketches.

Hot air: it is a collection of essays written by Lu Xun 19 18 to 1924. At that time, China was in the darkest age, and many people with lofty ideals were exploring the root causes of social diseases. There were merciless cynicism and sentient satire in the cultural circles.

Grave: essays of Lu Xun 1907 to 1925, 1927 published in Xiamen. The author said that the relevant articles would be restrained, "build a new small grave, with burial on one side and nostalgia on the other." This is the author's self-deprecating remark.
