Mr. Lu Xun's "Autumn Night" in the central area of the text is: In my backyard, there are two trees, one is Zizyphus jujuba, and the other is jujube. There is only one jujube tree in Mr. Lu Xun's backyard, not two. In that case, the other one is a jujube tree, which refers to Lu Xun himself. The lonely fighters are the revolutionary parties after the Revolution of 1911. They are unwilling and unable to start the masses, but only want to work alone to resist the struggle of the Beiyang government. Some of them are like the hero in Childe Harold, that is, the Byronic hero.

There is not one Zizyphus jujuba tree, but there is no connection between Zizyphus jujuba trees that are so close together, so that "one is Zizyphus jujuba tree" and "one is Zizyphus jujuba tree". This seemingly nagging remark of Mr. Lu Xun is intended to distinguish two like-minded Zizyphus jujuba trees, thus explaining the loneliness of the revolutionary party's struggle. Two wild jujube trees can't be twisted into a rope, and the revolutionary party can't form a monolithic team. Do you still hope that the revolutionary party can diligently start the masses? Later historical time proved that it is difficult to achieve success without the broadest participation of the masses.

This kind of writing also meets a habit of everyone's sight. When you see two trees at a close point, you can tell that the one at the close point is a wild jujube tree, and then look at the distance. At the same time, your sight is also facing the heights, so that you can see the trunk of another tree, and thus you can tell that both trees are wild jujube trees. This kind of near-far-slightly far and high observation sequence, just like the picture of the surveillance camera, presents two wild jujube trees one by one. At the same time, this kind of near-far-slightly far and high indoor space presentation is a calm and comfortable viewing scene assigned by Mr. Lu Xun for readers, in order to promote readers to look up from the side, so as to view the "weird and high" sky above the jujube tree.

When a literary master writes such a sentence that is different from ordinary people, it is not easy to fall into the problem of the general creator's procrastination in creation. Mr. Lu Xun's writing in this way must have its meaning. However, many scholars, even well-known literary critics, look at people's dishes and see that Lu Xun is a literary master, and he suddenly comes to the dust, preferring this sentence about Zizyphus jujuba trees beyond words, saying how well it is written, how superb it is, and how long it is interpreted. Some say it is an appropriate rhetorical device, some say it is to set off a simple one, and some say it is to better express it.
