1972, The Red Flag-Waving Youthful Era

In the spring of 1972, on a train heading to the Great Northern Wilderness for re-education, Chu Miaohong quietly tossed an old envelope into the wind. Far away in the year 2024, Zhang Hongcheng coincidentally received an old, worn envelope.

When Zhang Hongcheng's soul awakened in a young body in 1972, he decisively caused his insincere girlfriend and her family to suffer a total loss; sent the friend who had backstabbed him to labor reform; resolved the original body's decade-long grudge and reconciled with his stepmother; left the opportunity to stay and work in the city to his younger sister, and carrying that mysterious old envelope, he arrived in the Great Northern Wilderness.

The moment Zhang Hongcheng, carrying his luggage, jumped off the train, Chu Miaohong, who had fainted from heatstroke while working in the fields, slowly opened her eyes. From then on, the clock of fate began to turn. Amidst those vibrant youthful years, two young hearts eventually, slowly, found their way into each other's.
