Female protagonist, reborn in 1985 into the 20-year-old body of someone with the same name. She was switched at birth and raised by the poor Sheng family (pig butchers from the countryside) before being brought back to her biological Gu family a year ago. Trained as a successor to a family of doctors in traditional Chinese medicine, she practiced judo and sanda for physical fitness and knows acupuncture points. She is intelligent, decisive, and vengeful toward those who schemed against the original owner. She breaks off her engagement with Lin Qinghai, cuts ties with the Gu family, and transfers from nursing to the Chinese medicine department at Beijing University.
