My grandmother passed away in 2017. After I started school, my parents went away to work, and my younger brother and I were raised by our grandparents. Even on winter nights, the house was cold, and she would always warm my feet against her chest... Whenever I think of it, I remember the boundless love she gave me. Wang Xiulian in this novel is based on my grandmother. I wrote this story to honor how deeply I miss her.
