Part A Let’s learn
李白（701年-762年），字太白，号青莲居士，又号“谪仙人”，唐代伟大的浪漫主义诗人，被后人誉为“诗仙”，与杜甫合称为“大李杜”。
李白爽朗大方，爱饮酒作诗，喜交友，深受黄老列庄思想影响，有《李太白集》传世，诗作中多以醉时写的。李白所作词赋，宋人已有传记（如文莹《湘山野录》卷上），就其开创意义及艺术成就而言，"李白词"享有极为崇高的地位。代表作有《望庐山瀑布》《行路难》《蜀道难》等。
Li Bai (701 -762), a great romantic poet in the Tang Dynasty, was called "Poet Fairy" by later generations and "Great Li Du" together with Du Fu.
Li Bai is hearty and generous, loves to drink and write poems, and likes to make friends. He is deeply influenced by Huang Lao's thoughts of setting up a family. Li Taibai has been handed down from generation to generation, and most of his poems are written when he is drunk. There are biographies of Li Bai's Ci-Fu in Song Dynasty (such as Wen Ying's Record of Xiang Shan Ye). In terms of its pioneering significance and artistic achievements, "Li Bai's Ci-Fu" enjoys a very high status. His representative works include Looking at Lushan Waterfall, it is hard to go, Difficult Road to Shu, etc.
Li Bai traveled from the Tang Dynasty to modern times and met Wu Binbin and his father at school.
