This poem can be seen as a memorial to a deceased lover, or it can also be understood as a memory of a lost love. The whole poem describes the process of sweeping a tomb. First, the surrounding environment, then the weather, a few numbers bring people into the hazy atmosphere, and then the scenery creates emotion, describing the poet's feelings after losing his lover. The pain is beyond words, so much so that "I have forgotten the location when I was buried, and I only remember that I was facing the setting sun when I cried." It seems that only at this time can we connect with our lover and forget the barriers of time and space. In the second half, the poet's feelings sublimate, as if in a dream. In fact, this is also the poet's true yearning and best wishes for love. A series of parallels sublimates love to the highest level. At the last moment, the pen peak turned, and all the beautiful thoughts turned into nothingness and disappeared into the moonlight. In fact, everything is still going on, the only difference is the moonlight of tears every night.
