You have walked countless roads and seen countless scenery, which may be amazing or unremarkable. There will always be a moment when a small bud can touch you, and a little bit of heat can make you burst into tears. Being far away from home, I was not very sad, but suddenly looking back, the dearest person disappeared at the end of the road, the faint sadness turned into tears, and the sound of wheels on the asphalt road was heard. This is a short but long road that is engraved in my heart.
