The Poet Immortal (诗仙, Shī Xiān): Li Bai's most famous title is the “Poet Immortal.” This wasn't just a flattering nickname; it captured how people viewed his talent. It was considered so extraordinary that it couldn't be merely human—it had to be divine, effortless, and transcendent. His poetry often features mythical figures, celestial journeys, and a powerful connection to nature, reinforcing this “immortal” image.
Comparison to the “Poet Sage”: To truly understand Li Bai, it's essential to compare him with his contemporary, Du Fu (杜甫). Du Fu is known as the “Poet Sage” (诗圣, Shī Shèng). While Li Bai was a romantic, Du Fu was a realist. Li Bai's poetry soars with imagination and Daoist ideals of freedom; Du Fu's poetry is grounded, reflecting the suffering of the people and Confucian values of duty and social responsibility. This dichotomy—the Immortal and the Sage—defines the two main pillars of Tang poetry.
Influence of Daoism (Taoism): Li Bai's work is deeply infused with Daoist philosophy. This is seen in his reverence for nature (山水, shānshuǐ), his disdain for the rigid life of a court official, his praise of spontaneity, and his frequent celebration of wine as a means to achieve a state of freedom and connection with the cosmos. For a learner, understanding this helps explain why he wrote about the moon and mountains so much—it was a philosophical and spiritual pursuit.
