The everyday grind in the rehabilitation department: Lin Yu spends every day wielding a protractor against stiff joints, while Zhang Wei, trailing the scent of mugwort, is always after him to revise treatment plans. Today they wrestle with muscle tone; tomorrow they race to offer ice-cold cotton swabs to patients with swallowing disorders. Late at night, as they crunch the rehabilitation data, their shadows always draw closer on the treatment bed. After all the pain and laughter, they finally understand: helping someone who is paralyzed take their first steps again is more moving than any romance drama.
