My retirement life is happy and contented. I have spare money in my pocket, extra food in my hand, and a precious granddaughter who stays with me all day long. My filial daughter sympathizes with my hard work raising my little granddaughter. She not only cares about my health and takes me for a physical examination, but also offers to buy me a bigger house. But what I was waiting for was not the house book, but the birth certificate from the family planning office. "Mom, I want a son, please help me have one."
