In ancient poetry, the moon is a common image, which has always been loved by scholars. She is the carrier of people's emotions and has rich connotations: her ups and downs symbolize human emotions; Her quiet and soft moonlight can not only show people's leisure, but also set off people's sad mood; She is eternal, with eternal time and space, and short life ... These different meanings have formed different artistic conception and set off different emotions of the poet.
The moon represents: Acacia leaves sorrow, sadness, leisure and eternity.
