What are the author's thoughts and feelings, and what are they?

Ma Shuo expresses the author's thoughts and feelings that he used a swift horse as a metaphor to express his resentment against his talent and expose the feudal rulers' behavior of burying talents. = = = = = = = = It takes a long time to cultivate talents, and Boleyu can find people who appreciate and appoint talents. There was Bole first, and then there was Maxima, which was common, but Bole was not. It is necessary to find and care for talents, otherwise, talents will be buried, and talents are equal to no talents. In Han Yu's view, what is lacking in the world is not talents, but people who find talents. Therefore, what is revealed in the lecture is the author's feelings of talent failure and his resentment and accusation against the rulers for burying and destroying talents.
