What contribution did Li Bai make to Tang poetry?

Li Bai's poems and songs not only have typical romantic spirit, but also have typical romantic artistic characteristics from the aspects of image shaping, material intake, genre selection and the application of various artistic techniques. Li Bai successfully shaped himself in his poems, expressed himself strongly, and highlighted the unique personality of the lyric hero, so his poems have distinct romantic characteristics. He likes to express himself with gorgeous images. In his poems, he expresses his feelings freely and openly, showing his joys and sorrows. For dignitaries, he "holds a chrysanthemum and stirs two thousand stones" (one of the two songs "Send Cui Shiyu after Drunk"); Seeing the hard work of the working people, he burst into tears. When the country broke and the people perished, he "vowed to cross the river, aiming at clearing the Central Plains. He drew his sword and hit the front pillar, and the sad song was hard to recover ("South Ben Shu Huai"), so impassioned; When drinking with friends, "two people drink mountain flowers, one cup after another." I'm drunk and want to sleep. The Ming Dynasty intended to hold the piano (Drinking with Youren in the Mountain), so naive and straightforward. In a word, his poems vividly show his unruly character and eccentric image.
