Lady Tan's Circle of Women by Lisa See, Book Review According to Confucius, “an educated woman is a worthless woman,” but Tan Yunxian—born into an elite family, yet haunted by death, separations, and loneliness—is being raised by her grandparents to be of use. Her grandmother is one of only a handful of female doctors in China, and she teaches Yunxian the pillars of Chinese medicine, the Four Examinations—looking, listening, touching, and asking—something a man can never do with a female patient.
