When I was six years old, my mother died and my father left for the west exit and never came back. He fled to Sanyuan Temple, where Shen Laodao gave him a bowl of corn grits and changed his name: Shen Yexing. "Walking on the yin and yang path at night, doing human things during the day." From then on, people who walked at night had to walk forward in the dark without the sun shining on their heads.
