Xu Huizhen is the matriarch of the Gu family, a strict and biased mother-in-law. She forces Bai Suihe to observe daily rituals even when pregnant and ill. She favors the eldest and second branches, covets Bai Suihe's dowry, and maintains outward dignity despite her humble origins. She often pressures her daughter-in-law but is careful about her reputation.
