His capture by the enemy force shook the empire to its core, and the ensuing crisis almost caused the dynasty to collapse had it not been for the capable governing of a prominent minister named Yu Qian.
In order to prevent enemies from getting close to Zhu Jianshen, Empress Dowager Sun appointed Wan Zhen'er to be the prince's personal nanny.
When the emperor learned about Zhu Jianshen's relationship with Wan Zhen'er, he believed that the older palace maid had seduced the young prince and had her beaten with boards.
After Wan's son died aged ten months old, she jealously employed eunuchs to oversee the emperor's harem and report back to her if any concubines became pregnant.
For several decades, Lady Wan would use tactics including forced abortions and even murders of members of the harem to eliminate her rivals, resulting in the Chenghua Emperor lamenting that by the age of thirty-one that he still lacked a male heir.
Later, during the reign of the Hongzhi Emperor, Cao Lin (曹璘) proposed stripping away the title of Imperial Noble Consort from Lady Wan.
