A mother who had been submissive all her life was forced to stay in the world for seven days after her death. She floated on the ceiling, watching her body slowly rot, watching her daughter perform filial piety in her circle of friends, and watching the medicine bottle that she had replaced lying quietly on the bedside. In seven days, she finally saw the truth clearly - the daughter she loved with all her heart had been waiting for her to die. But the story didn't end after she was laid to rest. On the first seven nights, my mother came back. Only this time, she wasn't the only one who came back.
