余家驹的诗作反映了清代嘉庆和道光年间贵州人民的疾苦，揭露和鞭挞了当时官场的黑暗和丑恶，展现了祖国西南山水的雄奇壮丽。在文艺美学观上主张作诗要“自存面目”、“无格通灵”、“画中有诗诗有画”、“胸有奇特节”、“一字不着文更奇”。 Yu Jiaju’s poems reflect the hardship of the Guizhou people during Jiaqing and Daoguang periods in the Qing Dynasty, revealing and flaunting the darkness and ugliness of the officialdom at that time, and displaying the magnificent magnificence of the southwestern landscape of the motherland. In the view of aesthetics of literature and art advocated poetry to “self-preservation face,” “unqualified psychic”, “there is poetry and painting in the picture”, “chest has a special section”, “beyond the word more exotic.”
