As the sun rises, the footsteps of youth are approaching. We rode the express train of youth, and walked through every station happily, both bitter and happy.

We ran wildly on the small playground, and we told our stories to the sky like elves. Those whispers that only ourselves and our confidants can understand contain all the secrets of our bitter and happy years. ...

We swallow all the bitterness to our heart's content and let all the sadness disappear. Although there is nowhere to tell the pain, if it is hidden in our hearts for a long time, it will lead to a few drops of nectar, which will make people enjoy sweetness and endless aftertaste.

As time goes by, the books in front of the desk are getting thicker and thicker, the greetings from parents are getting more and more earnest, and our voice of shouting happiness is getting lower and lower every day.

Although this kind of voice was gradually suppressed by parents' reproaches, we still worked hard for our dreams and felt very fulfilled.

Happy us, let the soul dancing in the wind bring laughter to every place; Distressed, we are firmly trapped by the grievances and entanglements in life and cannot call for help.

Happy us, let the blood of singing wash away the dark clouds, beat drums and shout, and sing and dance on the avenue of youth; Distressed, we are bound by our inexplicable thoughts, but we can't escape, but we still smile bitterly.

These are our bittersweet years. Bitterness and pleasure are the signs of our life. It is also a symbol of youth. Youth is bitter, but also joyful.

Night falls, the lights are on, the footsteps of youth continue, the train of our youth is still running, and our bittersweet years are not over yet.
