Background: In the 1950s in Taiwan, there were rural streets at night, with a few gas lamps on both sides. The street atmosphere was scary. An old woman stopped at the door of a house and knocked on the door. There was a faint candle light in the window next to the door, and she could vaguely see the little girl. The girl looked over. The little girl is 8 years old. She is Asian. The houses on both sides of the street are dark. No one is picking up the phone.
