I'm not sure of a specific story that combines a Chinese farmer, a horse and a black swan. But generally, it could be a story about how the farmer's life is affected by the horse he owns, and then the appearance of a black swan (which is an unexpected event in the Western concept) might bring some unforeseen changes to his simple rural life, like new opportunities or challenges.
For it to be compelling, the story could involve the horse saving the farmer in a crisis or the farmer training the horse against all odds. It could also have elements of heartwarming friendship and personal growth for both the farmer and the horse.
Well, the obvious main character is the old farmer himself. He is the central figure around whom the story revolves.
Once upon a time, there was an old farmer. He had a small piece of land where he grew various crops like wheat and corn. Every day, he would wake up early, before the sun rose, and head to his fields. He worked hard, tending to the plants, removing weeds, and making sure they got enough water. His simple life was centered around the cycle of the seasons and the growth of his crops.
I'm not sure specifically what the 'used by old men story' is without more context. It could be a story that is often told among old men, perhaps a traditional tale, a war story, or an anecdote from their youth.
The main character is the old horse without a doubt. Depending on the version of the story, there could be a stable boy or an old man who owns the horse. These human characters play important roles in relation to the old horse. They interact with it, either showing kindness or depending on it for various tasks. But overall, it's the old horse that drives the story forward with its actions, its age - related situations, and its relationship with the other characters.
This sentence came from the classical Chinese text "An Old Horse Knows the Way", meaning "the wisdom of an old horse can still be used." The term "old horse" referred to an experienced horse, while "knowing the way" meant that he could arrive at his destination according to the road conditions and terrain. This sentence expressed the view that the wisdom of the experienced could still be used, and also hinted at the importance of wisdom and experience.
It could be a story of adventure as they go on long journeys together. Maybe they face challenges and overcome them with teamwork.
The old horse could be a warhorse that has retired. It now lives in a village. A young boy dreams of being a knight and the old horse becomes his 'training partner'. They go on pretend adventures together around the village.
