Lady Sun
Zhong Yao had another concubine, Lady Sun (孫氏), who was very jealous of her husband's other spouses and constantly sought to harm them or make them fall out of her husband's favour. When Zhang Changpu was pregnant with Zhong Hui, Lady Sun attempted to harm her and her unborn child by poisoning her food. However, Zhang Changpu was alert and she vomited out the food when she sensed that there was something wrong with it. Nevertheless, the effects of the poison still caused her to become unconscious for a few days. When she recovered, a servant advised her to tell Zhong Yao about the incident, but she replied: She then claimed that she was ill and remained indoors.
