李贺作为诗人的才华在当时引起文坛的惊异。他所作乐府也常在内廷歌唱。他凄苦的处境和出众的才能 ,使他抑郁感伤 ,国家的衰败腐朽又使他感到虚无幻灭 ,这是形成李贺激越凄戾 ,奇崛冷艳诗风的重要原因。 Li He as a poet’s talent at the time caused the amazement of the literary world. The house of his music is often sung in the court. His miserable situation and outstanding talent made him depressed and sentimental, and the decline and decay of the country made him feel nothing of vanquishing. This is an important reason for the formation of Li He’s poignant and unexpected poem.
