Emperor Huizong of Song
Zheng was born to a member of the gentry in Kaifeng. She served as a lady-in-waiting to Empress Xiang, who was the official mother of the future Emperor Huizong of Song. When Huizong was still only a prince, he lived outside the imperial palace and would often visit the empress, who instructed Zheng and another one of her ladies to wait upon him. In 1099, Empress Xiang arranged for him to marry Lady Wang. As a wedding present, Empress Xiang presented Zheng and the other lady-in-waiting, also called Wang, to him as concubines.
