It's 9:36 a.m. Fifty-five-year-old Gao Cuiling looks out of the window. She sees white clouds floating in the sky. She feels the sun is not so strong. And the breeze is gentle. She turns and smiles at her 2-year-old granddaughter: "Let's go downstairs!"

Her invitation is with a "wow!" from her granddaughter Zhang Junyao, and a "woof" from her dog. The little girl and the dog rush to the door. As soon as Gao opens the door, the two make a run for the elevator, without waiting for grandma.
