Fifteen years ago, on a spring night in Shanghai, young Lin Binyang was forcibly taken away from his hometown. He didn't even have time to say goodbye to the girl crying under the street lamp. When he returned fifteen years later, she was handing out flyers on the streets under the scorching sun. Before the joy of reunion has dissipated, a dusty old case has surfaced - her father was the key person who forged evidence and forced his family to death.
Hate is real, and so is love. During the war, she rushed to the front line to save lives and heal the wounded, and he escorted supplies across the Yangtze River. Two hearts riddled with holes finally found a way to walk side by side amidst gunfire and smoke.
But this is more than a story about love. The sycamore tree planted in 1947, the copper coin brought back from the Korean battlefield, and the old radio that was repaired for more than a hundred years and still broadcasts the weather - the old housekeeper Zhou Quanyou has guarded them all his life, and also guarded the belief that "good days will eventually come." From the War to Resist U. S. Aggression and Aid Korea to the Reform and Opening Up, from the return of Hong Kong and Macau to the take-off at the turn of the century, the fragrance of the sweet-scented osmanthus cake in the alley has not dissipated, and the people waiting under the trees have changed generation after generation.
The copper coins were donated to the museum, and the bracelets were passed down to the fifth generation of tree keepers. Old letters across the ocean have been decrypted, and the keychain that was lost a hundred years ago is about to return across the mountains and seas. All separation finds its way back in time.
It turns out that the deepest love in the world is not just choosing not to regret or complain even after hating. It's a tree, a copper coin, a radio, and generations of protection and waiting——
Where the roots are, spring is there.
