Classrooms, corridors, and the shade of old trees are the traces of our youth.
The letter I wrote to Zhizhi burned away a corner of it, and also burned away the reckless courage of my youth.
We have walked with each other through the best years and shared countless small joys.
But most of the youth is not perfect. After going round and round, we still go to different paths.
Dear classmate Zhizhi, I wish you well every year, that's all.
Purpose: The story wants to say that not all the heartbeats in youth can have results. Some people are amazed by the years, but they cannot stay with them for the rest of their lives. Regret is also a part of youth. Accepting the loss calmly is the best ending to that period of time.
