Picking up an abandoned baby on a snowy night, mechanic Guo Yongfu has had something to care about ever since. He used his rough hands to lift up a life, and eighteen years of steadfastness to fulfill a promise. From the bedding to the school, from gossip to the courtroom, he never let go of that little hand. Nuonuo grew up in love and fulfilled her dreams in books. This is not a story of blood ties, but a guardianship thicker than blood. Heavy snow can block the road, but it cannot block a heart going home.
