This is a unique farewell poem. When the poet was about to break up, he did not write countless parting words at all, but enthusiastically encouraged his friends to embark on a journey and meet the future. The first two sentences are endless layers of clouds, which have enveloped the whole sky, and even the sun seems dim and has lost its light. Only the well-organized teams go south in autumn and winter when the north wind is cold and the snow is falling heavily. It is natural to part ways in such a desolate age, but the artistic conception of this poem is clear and healthy. The last two sentences advised Dong Da not to worry about meeting bosom friends again in the future. Who in the world wouldn't appreciate an outstanding person like you? These two sentences not only express their deep friendship, but also highly praise a friend's character and talent, and sincerely wish him a future. It is rare that the farewell poem can be written so heroically.
