Records of the Three Kingdoms biography
Lady Wang of the ruler of Wu Sun Quan, was a native of Langye 琅邪 [commandery].undefined The Lady was selected to enter the palace and during the Huangwu 黃武 years she became favoured and gave birth to [Sun] He 和. She was the favourite, second to Lady Bu 步氏. After Lady Bu died, He was made heir-apparent (tàizǐ 太子), and Quan was going to make the Lady his empress. However the Princess Quan 全 [Sun Luban] had always detested the Lady and slandered her little by little. When Quan was lying sick in bed, she said the Lady [Wang] was looking happy. Consequently, he became very angry, and the Lady died of worries because of that. When He's son [Sun] Hao 皓 was made ruler, he gave the Lady the posthumous title Empress Dayi (Dàyì huánghòu 大懿皇后; literally “Empress of Great Exemplarity”) and appointed her three younger brothers as full marquises.
