Final answer:
The central theme in "A Tale of a Horse" is staying true to oneself, which is developed through the protagonist's experiences of facing and eventually disregarding external criticisms while preparing to present a horse to the king.
Step-by-step explanation:
In Ashford Wisterman's short story "A Tale of a Horse," the author develops a central theme of staying true to oneself amid external judgments and opinions. This theme is echoed through Huang's experiences as he prepares to present his horse to the king. Initially, Huang and his daughter walk alongside the horse, but after receiving criticism from onlookers, they change their approach several times in an attempt to please others. This conflict embodies the message that one should rely on personal convictions and not be swayed by the diverse opinions of others. This narrative detail is crucial as it underlines the story's moral: individual confidence and authenticity are more valuable than the varying standards of society. Huang's resolution to walk alongside the horse again, in the end, reaffirms his self-belief and the importance of making choices that are right for oneself, regardless of outside criticism or approval.
