Imagine a bunch of people 喁喁 whispering in a large room, and how their 喁喁 whispers 喁 echo across the room. Now 喁喁 whisper to agitatedly to the person next to you about how they should really keep the 喁喁 whispering down, lest the 喁 echo further amplify. Oh wait, now you're adding to the 喁 echos of 喁喁 whispers.
