In the long journey of life, "Those all left" seems to be a sentence full of sentiment and helplessness. Those people, things, and objects in the past have passed away like flowing water, leaving behind the traces of years and the thoughts in our hearts.
Those who have left, perhaps they are former good friends, who walked side by side with us for a period of time, and then gradually drifted away, leaving only memories hovering in our hearts. Or perhaps it is a glorious experience, as brilliant as a firework but fleeting in an instant, allowing us to realize the rush of time in the aftertaste. Or perhaps it is the former dream that gradually dissipated in the tempering of reality, but has become the cornerstone of our growth.
Each such experience is a kind of perception. It makes us understand to cherish the present, understand that things in the world are impermanent, and more importantly, it inspires us to keep moving forward on the road in the future, to pursue the goodness that has not gone far, and to create more memorable moments.
