What do the last two sentences of the poem Chang 'an Hakka Love mean and what feelings are expressed?

The first two sentences are about the poet passing through thousands of households in one day, but none of them is his home. What image? Nature is the image of a wanderer wandering around the world. There is a sense of desolation and helplessness in running away from home.

The last two sentences echoed this feeling of running away from home, saying, "I am not as good as the dust raised on this road." At least they can step on the earth with horseshoes and return to the earth, which is also the embrace of home.

If we just talk about the image, it is the image of a wanderer who has left his hometown.
