Li Shangyin had been drifting all his life,living in the shogunate for a long time.He had been living a poor life,and suffering the pain of the death of his families in middle age.These tragic life experiences prompted him form a sentimental and easily hurt personality traits,and created a series of poems which have illusory and hazy dream images to express his inner feelings.The dream image in Li Shangyin's poetry is illusory,ethereal,and rich in connotation.It can be broadly divided into three categories:dreams of goddess,which express his yearning and pursuit of beautiful love;dreams of ideal,which show his desire to make a difference;and dreams of return,which reflect his deep yearning for families and hometown.These poems with dream images truly show the subtle and secret inner world and emotions of Li Shangyin.At the same time,it also formed the unique style of ambiguous and implicit poetry and had a certain influence on the creation and development of euphemistic words in later generations.
