hen Yu wanders away from her father at a busy market. A mysterious fortune teller helps Zhen Yu's father find her, but also warns him that one day his daughter will be bitten by a snake on her wedding night. Years later, as Zhen Yu is dressing for her wedding, a knock comes on the door. Although it is her wedding day, she is not too busy to show kindness to a stranger. She opens the door, sticking her hairpin into the silk wall, unknowingly killing the lurking snake that the fortune teller had foretold. "It was the mitzvah of giving to the poor that kept you safe," says her father. Based on the Talmudic tale of Rabbi Akiva's daughter and a snake.
