A study of the historical materials of the Kangxi harem found that in the middle and late period, Kangxi became more and more fond of Han concubines, and these Han concubines were not from the Han military flag, but from the pure Han women of the people. Of course, in order to hide the eyes and ears of the people, Kangxi rarely canonized these Han concubines, but there was a Han concubine who bore Kangxi three sons and made great contributions, so she was crowned by Kangxi, and she was Shunyi Secret Concubine.
Regarding the origin of Shunyi's secret concubine, the official historical materials are not recorded, but through some clues, it is found that this woman is related to a small hair (milk brother) of Kangxi, who is a small hair child of Kangxi, named Li Xu, who used to work as a weaver in Suzhou, and it just so happens that Shunyi Secret Concubine is a Suzhou native.
According to the "Records of the Southern Tour of the Holy Driver", shunyi's secret concubine Wang's father made a living in suzhou Dongcheng, and the Wang clan was taken to the capital when she grew up, and later was incorporated into the harem by Kangxi and became a favorite concubine. At that time, Tang You, the director of the Henan Xuezheng (Department of Education), recorded several poems given to Li Xu in a book called "The Collection of Huaiqingtang", and these poems such as "There is no golden door millet in the bag, and there are beaded people in the family", which confirmed that Li Xu's family members had a woman entering the palace as a concubine, and after examination, this woman was Shunyi's secret concubine, and she was Li Xu's uncle and cousin (Note: Li Xu's concubine was Wang).
Moreover, at that time, the Wang clan was very favored in the harem, starting from the thirty-second year of Kangxi to the forty years of Kangxi, the Wang clan gave birth to three sons for Kangxi, namely the fifteenth son of the emperor, Yin Lu, the sixteenth son of the emperor, and the eighteenth son of the emperor, Yin. Among the three sons born to The Wang family, the most favored by Kangxi was the eighteenth son of the Emperor, Yin Yuan, so that Yin Gong began to follow his father Kangxi on a tour at the age of seven, but in the forty-seventh year of Kangxi, Yin Gong died on the way to the siege, only eight years old.
Moreover, Yin's death also directly led to Kangxi's first deposing of the crown prince Yin, who had no worries at that time, so that he was reprimanded by his father Kangxi, and later made a foolish act of spying on Kangxi, thus Kangxi deposed the prince who had been established for more than thirty years.
Although the eighteenth son of the Emperor, Yin Gu, died early, the sixteenth son of the Emperor, Yin Lu, was reused by Yongzheng, who succeeded him later, and Yongzheng even allowed Yin Lu to inherit the title of Prince Zhuang's Iron Hat King, so it can be seen that perhaps Yin Lu had become a member of the Fourth Master Party in the late Kangxi Period.
After Qianlong succeeded to the throne, Yin Lu became the prime minister, and at that time, Yin Lu wrote to Qianlong to request that his mother Wang Shi be taken to the family for support, but Qianlong did not agree. However, Qianlong still allowed the Wang family to go to his son Yinlu Mansion for a period of time during the New Year's Festival, which was enough to give the old lady face.
On October 16, 9th year of Qianlong, Wang Died of Illness in the Palace at the age of 70, with the nickname Shunyi Secret Concubine, and was buried in the Jingling Concubine Garden.
