Female, Gu Jingyao's older sister. She is described as strong, wearing a checkered shirt with a short wavy perm, looking like an angry dog. She is greedy and reckless, having spent 80 yuan (her husband's two and a half months' salary) on a worthless blue-and-white porcelain jar she mistakenly believed was valuable. She has no professional knowledge of antiques despite being exposed to them since childhood. She is resentful of Lin Moran and tried to force her to buy the jar. She once told a suspect that department stores are public property so stealing is acceptable, which led to a robbery case.
