Huilan is a female minor character mentioned in the story. She is the source of information for He Dachuan's husband about the price of sugarcane in town, which Huilan reported as sixteen wen per jin. This is higher than the twelve wen per jin that Liu Guyu pays He Dachuan, which causes He Dachuan's husband to complain that Liu Guyu is ripping them off. Huilan's exact relationship to the other characters is not specified in this text, but she appears to be someone who has information about market prices in town.
