This sentence comes from Lu Xun's "Self-deprecating" article. The original text is: "So I sat up, took out a pen washi, and wrote a few words on the paper: 'There are no roads in the world, and the more people there are, the more roads there are." Then, I showed it to my father. After he saw it, he smiled." The meaning of this sentence was that there were no roads in the world, but people kept walking and found new roads. It emphasized the importance of creativity and the spirit of exploration, and it also told us that as long as we have the determination and courage, we can discover new possibilities on the unknown path.
