I sneakily asked my grandfather, "You get up early every day to cook, three meals a day, and then you go to work. You do this every day, even on legal holidays. Don't you ever get tired",“Your grandfather was warming your grandmother's feet. Your grandmother wasn't feeling well and always had cold hands and feet. Your grandfather felt sorry for her. Just pretend you didn't see it, don't ever tell your grandfather about this.”,“Because your grandfather will make you write big characters as a punishment.”。
