If life were an essay, what kind of poem would you write? This is a story that happened in the Yimeng Mountains. 9-year-old Xinxin is a lonely child living in the city. His parents are busy all day long and have no time to accompany him. At the time of grain in ear, his mother was on a business trip, and his father sent Xinxin back to her grandfather's house in the countryside. In a few days, the grandfather and grandson became affectionate from strangeness. After learning why grandpa did not want to go to the city to reunite with his family, Xinxin wrote an essay. The contradiction and estrangement of the family, the fetters of three generations of grandparents and grandchildren, have since begun to subtle changes.
