An ordinary young man, Liu Shisan (played by Peng Yuchang), lost himself in the city and was taken back to his hometown by his grandmother (played by Alia), a small town on the edge of the clouds. Accompanied by his childhood friend Cheng Shuang (played by Zhou Ye) and his grandmother, Liu Shisan spent a peaceful time. Following the traces left by his ancestors, he listened carefully to the breath of the town, and gradually walked out of the confusion of the past in the store where he could touch the clouds, between the mountains and the sea, and under the osmanthus tree in the yard. Some people are unforgettable and forgotten in a few years. Some people stay with you regardless of life or death.
