Emperor Qianlong was lustful. There were rumors that he had committed incest with his sister-in-law.

Emperor Qianlong of the Qing Dynasty is described in history as an amorous and romantic emperor. He went to the south of the Yangtze River six times in his life. In addition to inspecting local people's sentiments, it was also interpreted that he had an important purpose, which was to visit the beauties of the south of the Yangtze River. In fact, Qianlong's favorite one was his first wife, Queen Fucha. Qianlong had three queens in his life. The first, Fucha, was his direct descendant Fujin whom he married before he became emperor. The two were only fifteen or sixteen years old at the time. They spent their youth together as childhood sweethearts, and their relationship was very good along the way. After the death of Empress Fucha, Emperor Qianlong was so sad that he went on a killing spree. He ordered people to keep all the items in the queen's palace as they were, and he insisted on going to her funeral every year to write poems in condolences. From this point of view, Emperor Qianlong could be said to have a deep love for Empress Fucha. But the reason for the death of Queen Fucha was actually related to Qianlong.
Qianlong regretted his life because he felt that he had indirectly killed his wife. What happened that caused this loving couple to be separated forever?
The emperors of the Qing Dynasty were actually very particular about their mother's background. One of the few exceptions was Emperor Jiaqing's biological mother, his concubine Wei Jia. It is said that her origin was just a servant of the Ministry of Internal Affairs, and she was not even qualified to participate in the emperor's draft. Judging from this, your concubine should have been just a little palace maid when she first entered the palace. But in the year when Empress Fucha died, Wei Jia was granted the title of Imperial Concubine by the Jin Dynasty. According to historical records, she had a gentle and graceful personality, and within ten years she gave birth to six children for Qianlong, including the future Emperor Jiaqing. Qianlong's love for her is evident, and she even became an imperial concubine after the "conflict between emperor and empress" in the thirty years of Qianlong's reign. But even though it was so favored, many years after its death, the mother was posthumously named Queen Xiaoyi because of the value of her son. What was the reason for this? How did she make the passionate Emperor Qianlong become deeply fascinated by her?
The description of Qianlong's harem in the drama is all about the struggle between the concubines and concubines, who resorted to various insidious means. But from another perspective, Emperor Qianlong had a shrewd mind and a complex and elusive personality. In fact, all the women in the harem were under his control and were also pawns in his political operations. It can be said that the concubines in the harem worked hard to get their son to sit on the throne of the prince. Qianlong seemed to be a sandwich cookie, but in fact he had his own management model. Emperor Qianlong's devoted love for Empress Fucha, his exclusive favor for his concubine, and his seemingly romantic and affectionate character actually reflected his ruthless side. How did Qianlong become the biggest winner in the palace battle?
In order to stabilize his power, Qianlong even used his beloved Queen Fucha. Even Empress Fucha's younger brother Fu Heng, although highly used by Qianlong, was just a pawn in his hands. Qianlong built an ancestral hall for the Fucha family, and continuously promoted Fu Heng to officials and titles to reward him for his outstanding military exploits. He also loved and cared for his sons, especially Fu Kang'an, Fu Heng's third son. Not only did he let him enter the palace to study with the prince, he was also named Beizi, and he was even named king with a different surname. Therefore, there are rumors that Fu Heng's beautiful wife was once tainted by Qianlong, and Fu Kang'an was their illegitimate son. Is this really the case?
It is difficult to understand the emperor's mind, and Emperor Qianlong's mind was even more complicated, because every move he made was related to the political situation that was not yet stable at that time, and it could not be concluded in one or two sentences!
