When I am young, I always want to pursue some distant place. Pursuing the distant road is the infinite expectation of my parents. I always feel that hope is ahead, so I bid farewell to my parents with reluctant eyes and embark on the endless road. The support and departure of friends along the way, the passers-by in front see the reality clearly and run for life, while the people behind only want to see the world in front, but only when they reach the front do they realize that the starting point is that far away, but can they still go back?
