I am an ordinary person. The only difference is that I have a pair of disabled grandparents. There is a lot of happiness but also a lot of helplessness and sadness in getting along with them. I once heard them talk about their past, and now I only use this book to commemorate my childhood and my grandparents. I hope they can become a happy pair of ordinary people in another world. ——Zhao Wen
