It is not a cheer, after all, the Qianlong Emperor Hongli's lifelong love Fucha clan has been promoted, and if the performance is too obvious, it is simply looking for death. After Empress Fucha's death, there were indeed two princes who seemed quite excited, one was the emperor's eldest son Yong Huang, and the other was the emperor's third son Yong Zhang.
When it comes to the death of Fu Cha, why the two "unworthy sons" are so happy, then we must first talk about the special imperial succession system of the Qing Dynasty.

As we all know, China has always implemented the "primogeniture inheritance system", even though there are very few monarchs in successive dynasties who have really inherited the throne as the eldest son or even as a concubine, but the basic principles have not changed, until the beginning of the Qing Dynasty.
The Kangxi Emperor Xuanye had many concubines, so the heirs flourished, and at the same time, many heirs also caused a fight, and the famous "Nine Kings Took The Concubine". Therefore, starting from the Yongzheng Emperor Yin chan, a system of "secret reserves" was established, and from then on, the reserves were no longer openly established.
The empress dowager was deeply in love, and the Qianlong Emperor loved Empress Fucha, empress Fucha, who was of noble birth and the first woman in Hongli's life. As early as when Hongli was the Prince of Bao, he had already become the concubine of the prince's palace. It seems that in the traditional impression, the feelings between the emperor and the empress are mostly out of political purposes, not love, but Hongli and Fucha are different.
Although it is not free love, the queens are truly respectful and loving.
The Qianlong Emperor Hongli was the son of the Yongzheng Emperor Yinchen, and although he also pursued the "secret reserve" system, he was very fond of the son of the Fucha clan. Empress Fucha had two sons in her lifetime, and although they died prematurely, both sons, the Qianlong Emperor, directly and publicly stated that they wanted to be crown princes.
After the death of his mother-in-law, why did the crown prince not show sorrow for thirteen years, Empress Xiaoxianchun was promoted, and Yong Huang was mourned as the eldest son of the emperor. However, on top of the funeral, the Qianlong Emperor reprimanded Yong Huang and Yong Zhang for not showing enough sadness, and at the same time publicly announced the disqualification of the two as reserves.
In fact, if you think about it carefully, Qianlong himself is also overly sad, first of all, Yong Huang was only twenty years old at that time, Yong Zhang was only thirteen years old, neither of them was born to the empress, Yong Huang was born to the noble concubine Fu Cha of the Zhe Mercy Emperor, and Yong Zhang was born to the pure Emperor Noble Concubine Su Shi. It wasn't his birth mother who died, and it was normal for the two to not be so sad.
On the other hand, Qianlong was extremely fond of Empress Fucha, and if the empress had another concubine, she would inevitably get the throne, and now that the empress was promoted, it was naturally an opportunity for Yong Huang Yongzhang. However, no one can imagine, but it is self-defeating.
