Youth is a ray of sunshine in the morning, fleeting, but wonderful; youth is also a touch of sunset on the horizon, fleeting, but beautiful; youth is a bright star, which always gives people endless reveries and leaves indelible traces in the memory.
Although youth is short, it has no regrets.
This is the youth of one person and the youth of a group of people.
This is the still water that runs deep for one person, and the eternal life of a group of people.
