Gong Luozhou's couplets depict what happened when he entered the Yellow River and gave it to friends in Fuxian County. What emotions does the poet reflect?

Gong Luo Zhou entered the Yellow River and sent his friends to Fu-fu, a seven-character poem written by Wei, a poet in the Tang Dynasty. This poem was improvised by the author when he entered the Yellow River from Luoshui, and was given to his old friend in Luoyang County.

This poem describes the scenery with feelings and sustenance, focusing on celebration and vivid freehand brushwork. On the way to Luoshui, the poet seemed to be enjoying the scenery, but in fact he was absent-minded and lost in thought. The wide sight of the Yellow River seems to have startled the poet, making him suddenly enlightened and look out. However, what he saw made him even more helpless and sad. Looking around, it is bleak: the old Yishui lonely village shows how deep the people have experienced; A wild goose flying in the north wind, just like a poet going to the post in the East alone, knows when to fly and saves the world from hope. So he remembered the encouragement and expectation of his friends, felt sad and guilty, and felt that he was an incompetent person who had nothing to ask for after all, and it was difficult to realize his love for the world and his ambition to struggle. This is the sentiment in the scene of this poem.
