This poem was written by the poet while studying in Japan. Considering the background and the poet's situation at that time, we can feel that at that time, the author was disappointed with reality and missed his motherland, hometown and relatives. At this moment of moonlight, although the poet wrote that Jiao Ren was sprinkling pearls on the moon, it was actually the poet himself who shed tears on the moon. The poet's sadness, helplessness and melancholy at this time turned into tears to express his sadness and thoughts. The author's purpose in writing about Jiao Ren is to write his own feelings, but through such association and imagination, it is both subtle and beautiful.
It can be summarized as: a sad story, expressing the author's disappointment with reality and homesickness for his motherland, hometown and relatives.
