Kaishan 1975

The late 1970s, northern Sichuan. The sound of cannons opening mountains and building roads sounded like a hero's call to Gui's baby, but to Brother Jun's ears, it sounded like the hope of saving money to treat his father's eye. One wants to escape from the classroom, and the other wants to illuminate the darkness. When the roar of the mountain's explosion finally sounded, it swallowed not only the rocks, but also the words of a young man who had not yet spoken.
