"Road" refers to the road of life, telling us to choose carefully. Once chosen, it is difficult to look back.
This poem is about the road of life. The end point written by the poet is not the road that has been chosen. This is mainly to deepen the subject. The poet laments that there are many roads to choose from in life, but there are still many roads that have to be given up. The choice of life path is accidental and arbitrary. Those roads that have not been traveled make people miss and miss them even more. The poet's lament about the path chosen in the future can touch the readers' hearts more deeply and make people think more deeply about life choices.
It shows the poet's hesitation, choice and melancholy psychological activities.
