The meaning of the whole poem: Chang 'an's family looks thousands of miles east, tears wet their sleeves and blur their faces. Meet in a hurry, no pen and paper. I just want you to report the safety of my family.
This poem describes a typical scene in which the poet traveled far from the frontier fortress and met an envoy who returned to Beijing on the way, bringing a message of peace to comfort his family, which has a strong human touch. The language of poetry and prose is unpretentious, but it contains two feelings: homesickness and yearning for fame, affection and pride, interweaving and blending, sincerity and nature, and touching.
