The word 'swarm' meant that they were coming like a swarm of bees. It described a lot of people gathering in a place in a mess. This idiom came from the twenty-sixth chapter of Li Ruzhen's Love in the Mirror and Flowers in the Qing Dynasty. It described the scene of many people wearing Haoran headscarves and holding mobile phones. It can be used as a predicative or an attributive, referring to the disorderly gathering of people. Synonymbs swarmed over, while antonyms swarmed in, followed, and so on. This idiom was commonly used and neutral, and was produced in modern times. The English translation was "surge in."
Swarm fiction is a form of collaborative storytelling. It involves multiple authors or contributors coming together to create a single work of fiction. Each person adds their own ideas, plot twists, or characters, and over time, the story evolves in a unique way. It's like a digital-age take on the old - fashioned story - telling circles, but with the potential for a much larger and more diverse group of contributors.
