I believe everyone knows the Hua Fei in The Queen of the Palace very well. She is Nian Gengyao's sister. With the strength of his brother Nian Gengyao, he was overbearing in the harem, regardless of the queen. Although the emperor likes her very much, in fact, only the emperor and the queen mother know why she likes Hua Fei. Hua Fei has been infertile for many years. All this was inspired by the Emperor and the Empress Dowager, in order to prevent Nian Shi from having boys. In addition, the relieving power of Nian Gengyao will make the rights of Hua Fei in the harem more and more difficult to control in the future. In the final ending of "Hua Fei, the Queen of the Palace", she committed suicide by hitting a wall because she knew the reason for her infertility for many years.
In fact, in history, Hua Fei, that is, studying Shi Lan, is a prototype of Dunsu imperial concubine. She gave birth to four children for Yongzheng in her life. Nian Shuyuan in the TV series Flowers in the Palace is actually rehabilitating Hua Fei in the Queen of the Palace. She is not an open-minded woman. Hua Fei in history was very clever and was liked by many people when she was young. She is not arrogant. She's really smart and cute.
In the play, Nian Shuyuan had an emotional scene with the prince and the May 4th Movement. Later, she married the May 4th Movement, when she was still a prince. After Yongzheng ascended the throne, she became a concubine. In those years when Nian Shuyuan and Yongzheng were together, although they gave birth to four children, they all died later. In fact, Yongzheng's love for Hua Fei was not entirely due to the rights of the family, but really loved her, and was chased as the imperial concubine after Hua Fei died of illness. Even if Nian Gengyao is found guilty, the rest of the family will not be implicated in any way.
