My grandma passed away in 2017. My parents went out to work when I was in school. My brother and I were taken care of by the elderly. The house was relatively cold at night in winter. She always put my feet in her arms to keep them warm... Every time I think of her, it is her endless love for me. In the novel, Wang Xiulian is the prototype of my grandma. I wrote this novel to commemorate my endless longing for her.
