The author Luo Jinfen met an old woman sweeping tombs on April 5, 1957, in Xiaobei, Guangzhou. The five or six centimeters long scar on the upper corner of her left eye and her impolite coldness deeply imprinted on the author's heart. When the author met her for the second time, she finally sat down and no longer insisted on leaving. She looked at the author solemnly and said, "Sir, you are an honest person, I can tell you my family history. But there are three conditions, you must promise me."
