When history teacher Lin Jing wrote "Since ancient times, heroes have emerged as young men" on the blackboard, she opened a dialogue for the students through time and space - an encounter with those souls who illuminated the times when they were young.
From Gan Luo, who was sent as an envoy to other countries at the age of 12, to Huo Qubing, who was a wolf and lived in Xu at the age of 17; from Xun Guanniang, who broke out of the siege of the city at the age of 13, to Liang Qichao, who wrote "Young China" at the age of 19... Twenty-eight young people, living in different eras, responded to the challenges of fate with the same courage.
This is not a catalog of heroes, but a symphony of "possibilities". When young people encounter critical moments in history, they choose to step forward - using their wisdom, blood, pen and ink or life to write answers that transcend their age on the answer sheet of the times.
