In the setting sun, the woman picked up the glass and looked at her sweetheart who was about to go to the frontier with tears, and drank it down; on the one hand, there was the love of her children, and on the other hand, the country was righteous. The man took a difficult step away. This song is a piece of pure music, with the sorrow of parting, the tenderness of missing and the righteousness of the country. It is suitable for use in film and television dramas, documentaries, short videos and other similar emotional project scenes.
