Looking up at the starry sky, I would leave everything all behind, as if I’ve returned to the embrace of my mother. Three years ago. there was a back door where I lived in Nanjing and each night when I opened the back door. I could enjoy a silent night. On the ground existed a vegetable garden and in the sky was the star-studded blue sky. Tiny as the stars in our naked eyes, they give us a sense that the light is all-pervading. In those days I was reading some books about astronomy and I could distinguish some stars, as if they had been my friends and often talked to me.
