The original title was “not around the mountain,” published in Beijing on December 1, 1922, “Morning Memorial Week Memorial Supplement,” later incorporated into the “cry” of the end of the volume. In 1930 January “cry” thirteenth printing Lu Xun deleted this article, 1935 income “story” when changed its name to “fill the sky.” Speaking of Lu Xun’s novels, people think of “Mad Men’s Diary”, “Ah Q”, “blessing”, “medicine” and other realistic subject matter works, while the “sky” concern is relatively small.
