His father is like a little boy, sometimes even mistaking his son for a buddy, yet he never forgets that he needs to pick his son up from school. Amid life's heavy burdens and family conflicts, the family eventually learns to understand and accept one another through their struggles. Time may steal an elderly person's memories, but it can never erase the deep bonds of family. This is a heartwarming and healing story about perseverance and responsibility, vividly illustrating the touching filial devotion behind the saying, 'You raised me when I was young, and I will care for you when you grow old.'
