As of now, the cause of death of Queen Fucha is still indefinitely.
Initially, the Fucha family was designated as the legitimate concubine of the prince of the Hongli by Emperor Yongzheng . When Qianlong was appointed emperor, Fucha was granted the title of queen.

In the following years, although more and more beauties appeared in Emperor Qianlong's harem, he and the queen Fucha still loved and respected each other. However, this warm time did not last long, and three of the four children of Queen Fucha died one after another.
This caused a heavy blow to Fucha's spirit, and the excessive grief gradually worsened her health.
In the 13th year of Qianlong's reign, Emperor Qianlong traveled eastward. He took the Empress Fucha family, and they went to the Confucius Temple together and moved to Mount Tai .
However, on the way back to the palace, Empress Fucha suddenly passed away at the age of 37. 11 days later, Emperor Qianlong personally named Empress Fucha Empress Xiaoxian .

The cause of her death has not been verified yet, and many people believe that she was framed by someone.
In addition, there were rumors that the Empress Fucha at that time discovered that the emperor had secret contacts with her sister-in-law, the wife of Grand Secretary Fu Heng . suddenly fainted and died suddenly on the ship. There is also a legend about
. In fact, at the beginning of the tour, Queen Fucha's body was already very weak, but she was afraid that the emperor would worry, so she tried her best to be with him. But in the end, she could no longer hold on and died on the boat on the way back to the palace.

Although it is not clear what the cause of Queen Fucha's death was, the undeniable fact is that when she passed away, Emperor Qianlong felt regret and grief. The Changchun Palace where Empress Fucha lived was still intact, and the emperor no longer allowed concubines to live here. It was not until he abdicated that he accepted that others moved in.
, and even, among the tens of thousands of poems written by Emperor Qianlong, hundreds of them were written to commemorate the queen Fucha.
