What is 520?
It was the string in the middle of the table when I was a teenager. The neat handwriting on the exercise book and the ponytail swinging back and forth on the way home from school. It's the rubber band during the break and the blue and white school uniform
It was the stop of Bus No. 120 in the winter of Beijing when I was young, on rainy days. It's a dilapidated bungalow with trees in the courtyard within the Second Ring Road. It's a big pancake from Chaonai Market. It's every embrace that rushes out from the street corner. It's Yanjing and grilled skewers. It's a bench in the old courtyard at midnight. Which wandering magazine is it?
It was the corridor of the obstetrics and gynecology hospital in middle age, the first time I held his excitement and his smile at me. It was the first time I called him "Dad". Which sentence is it, "Bring him to this world to save me"...
