In the long corridors of the General Hospital of the Military Region, the surgical lights flickered on and off, while the soft, steady sound of a stethoscope filled the air. Jiang Han, a calm and decisive surgeon, met An Nuan, a gentle and empathetic psychologist. The scalpel cut through the haze of illness, while the quiet words in the counseling room soothed the creases in people's hearts. From the mutual admiration of their first meeting to the warmth of building a life together, they made a home full of everyday comforts as they worked to save lives. The birth of their daughter, Jiang Niannuan, gave their love a future. Following in her parents' footsteps, she put on a white coat and made responsibility and tenderness part of her very being. From the cozy daily life of a family of three to the calling passed down through three generations of doctors, the days and nights at the military hospital hold the most moving devotion and the deepest happiness.
