This essay endeavors to dispel the lingering misconception that Li Bai, the celebrated Tang Dynasty poet, was a man devoid of propriety. Through a meticulous examination of historical records, literary works, and contemporary interpretations, this study presents a nuanced portrait of Li Bai as a poet who, despite his eccentricities and wanderlust, possessed a profound sense of etiquette and respect for societal norms. This essay argues that his unique personality in life and free expression in poetry are all driven by the need for artistic creation, rather than challenging for ancient propriety.
