Help me translate the Book of Songs.

Before leaving home for war, the willows were gentle and danced with the wind. Now back home, snowflakes are flying all over the sky.

This is a poem about a soldier who was sent to the frontier from going out to going home. These four sentences are famous sentences with a blend of scene and scene in the poem. The overlapping words of "Yiyi" and "Feifei" not only vividly describe the graceful figure and heavy snow of Liuzhi, but also reveal the inner world of this move. "Willows and Yiyi" shows his nostalgia for his relatives in his hometown when he went to the battlefield in spring. Rain and snow reminds us of many hardships he suffered during his journey, and it also sets off his grief and indignation after returning to China. Wang Fuzhi, a poet in A Qing, said that these four poems "write mourning with joy, mourn with Syaraku, and their sorrow is twice as enjoyable." (Jiang Zhai Shi Hua)
