I'm not sure specifically what the'short pebbles story' is. It could be about a collection of pebbles and perhaps an adventure they have, or it might be a story using pebbles as symbols for something like friendship or discovery.
I don't think it's a true story. Usually, such characters and tales are created in the realm of imagination to capture people's interest and maybe teach some lessons.
The Sand Pebbles is mainly a creation of the author's imagination. It might draw inspiration from real-life elements but is not a factual account of an actual occurrence.
The story of 'Sand Pebbles' is a mix. While it may have roots in reality, it incorporates fictional elements to make it more engaging and cinematic. So, it's not a straightforward true story.
Well, the '2 black pebbles story' could be a story centered around two black pebbles. It could be that these pebbles are special in some way. They might be magical pebbles that hold the key to a mystery in the story. Perhaps they are found by a character who is on a journey, and the discovery of these two black pebbles changes the course of their adventure. Or it could be a story about a competition where the two black pebbles are used as tokens. But again, this is all speculation without knowing the actual details of the story.
