This song is written from the perspective of a woman reminiscing about her lover. This is one of the most famous examples of the ci genre, and one of the best-known works of Yan Shu. The song lyrics depict natural imagery which mirrors and amplifies the speaker’s feelings of loneliness.

The ci genre of Chinese poetry first emerged in the Sui dynasty (581-619), was further developed in the Tang dynasty (618-907) and matured in the Northern Song dynasty (960-1127). Ci is usually translated into English as "song lyrics". This is because ci were composed by poets to fit pre-existing tunes. The number of lines, the line lengths, and the tonal and rhythmic patterns of ci vary with the tunes, which number in the hundreds. One common occasion for composing ci would be a banquet: song lyrics would be scribbled down by guests and then sung by musical performers as entertainment. Other occasions for composing and enjoying ci would be more casual: the poet might sing the lyrics to himself at home or while travelling (many ci poets were civil servants of the Imperial Court and often had to travel great distances to carry out their work). Sometimes the lyrics would be sung by ordinary people in the same way as folk songs. This oral and musical quality sets it apart from other genres of poetry in China during the same period, which were largely written texts with more elevated objectives. There are two main types of ci: wǎnyuē (婉约, "graceful") and háofàng (豪放, "bold"). The wǎnyuē subgenre primarily focuses on emotion and many of its lyrics are about courtship and love, while the háofàng subgenre often deals with themes that were considered more profound by contemporary audiences, such as ageing and mortality, or the rewards and disappointments of public service.

Yan Shu, a powerful statesman in the early Northern Song court, had a long and successful career both as an official and as a poet. Among his many literary achievements (which include poetry, song lyrics and prose) his ci compositions are best known. His lyrics are elegant in their choice of words, controlled in the emotions they express, and not as playful as the ci of other well-known poets. They often capture feelings of solitude and sorrow, creating a melancholic mood, but the poet is rarely explicit about what triggers the worry or sadness.
