After his grandmother passed away, Lin Feng fell asleep guarding the camphor wood box left by his grandmother. A dream that spanned seventy-four years brought him back to the time when his grandmother Shen Yuehe was seven years old.
In the dream, he turned into a distant brother, protecting the hungry and cold Ahe (grandma) from famine, fighting for the opportunity to study, accompanying her to meet her husband, and opening a silk workshop, fulfilling her wish to go to Beijing to see Tiananmen Square and the seaside.
After waking up from the dream, Lin Feng found at the bottom of the camphor box the secrets that his grandmother had treasured throughout his life - his baby teeth, graffiti and family letters, as well as a stack of sweet-scented osmanthus toffee wrappers. It turns out that this guardianship across time and space was never a one-man show. His grandmother loved him all his life and he grew up. He fulfilled his grandmother's life with a dream. The love between grandfather and grandson spans life and death and runs in both directions. In the cinnamon in the south of the Yangtze River, he is safe every year.
