First of all, Qin Keqing's true identity.
What is Qin Keqing's real identity? In the original novel, the author introduced her as the adopted daughter of' Yangshengtang' Qin Ye. However, it is impossible to marry Jia Rong, the eldest son of Ning and Jia Zhen, based on his family background and Qin Ye's family background. So Qin Keqing's apparent identity is not her real identity.
However, as for Qin Keqing's true identity, the author adopts the writing technique of half truth and half falsehood. In the fifth episode of A Dream of Red Mansions, when introducing the furnishings in Qin Keqing's room, the author described it like this:
On the case, there was a precious mirror set in Wu Zetian's mirror room that day, and there stood a gold plate of a swallow, in which An Lushan threw a papaya that was too hurtful. There is a couch where Princess Shouyang and His Royal Highness Zhang lie together, and there are couplets made by Princess Tongchang.
We know the things described above, of which the first three are imaginary and the last two are real. The first three things have a common feature, that is, the three women related to these three things are all emperors' concubines. The "Shouyang Princess Bed" and "Tongchang Princess Joint Account" described later belong to real writing.
Virtual writing means that people are not in things, while real writing means that things are not in people. In other words, the author describes the first three things in order to highlight such an important message as "the emperor's concubine". Through the description of the latter two things, the author aims to highlight such an important message as "the princess's bed and the princess's bead account".
To sum up, Qin Keqing sleeps on the princess's bed with the princess's beaded account. She is related to the emperor's concubine, so there is only one possibility. Qin Keqing is the daughter of the emperor. However, Qin Keqing was adopted by Qin Ye of Yangshengtang, indicating that Qin Keqing was the illegitimate daughter of Qin Shihuang.
Second, Qin Keqing's real cause of death.
In the fifth episode of A Dream of Red Mansions, when the author gives Qin Keqing's verdict, he gives the ending of Qin Keqing's "hanging" through a painting related to his verdict.
We can't help asking, as the future housekeeper of Ningfu, Qin Keqing has a luxurious life envied by countless people. Why did she hang herself? From the following article, we can know that Qin Keqing hanged himself for two reasons, one was despair, and the other was shame and indignation.
Qin Keqing's Despair: A Dream of Red Mansions, Episode 11. After getting sick, Feng went to visit her. She said to Feng, "Whether you leave the immortal or not, you can't cure your illness." Why is Qin Keqing sick? From the hint of the author's detailed description, we can know that Qin Keqing had a miscarriage at that time.
As we know, there is a certain relationship between Qin Keqing and Jia Zhen that goes against human feelings. As can be seen from Jia Rong's attitude towards Qin Keqing, he should not like women. Otherwise, how could he treat Qin Keqing as a beautiful and affectionate wife as if nothing had happened? In this case, even though Qin Keqing is rich in luxury goods, what can life expect?
Qin Keqing's shame and indignation: Although Qin Keqing's situation made her desperate, people always wanted to live and not die, but before the last moment, no one would end his life easily, but Qin Keqing suddenly hanged himself.
After Qin Keqing hanged herself, the maid crashed into the column and died, and her mother-in-law You Shi became ill. Visible when Qin Keqing died, Ningfu "event" happened. This "great event" not only made Qin Keqing's master and servant both commit suicide, but also made her mother-in-law sick. This "big event" can only be that the affair between Qin Keqing and Jia Zhen has been thoroughly exposed.
During Qin Keqing's illness, judging from her mother-in-law's concern for her, mother-in-law You-shi naturally didn't know about her and Jia Zhen. We know that if something doesn't pierce enough paper, everyone can pretend that nothing happened and live in peace. But once everything is on the table, there will be no old friendship and no old good days.
Imagine that for Qin Keqing, she loves her mother-in-law so much, but she has an affair with her father-in-law. How will she face her mother-in-law in the future? How can you pretend to be a "talented and good-looking" grandmother Rong? Therefore, in shame and despair, Qin Keqing hanged himself.
The relationship between Qin Keqing's death and Yuan Chun's Jinfeng: Although Qin Keqing hanged herself, Jia Fu clearly declared that she died of illness. As we said before, Qin Keqing is the illegitimate daughter of the emperor. As the daughter of the emperor, she was abandoned as a child and later adopted by Qin Ye. She didn't get her birthright, honor and dignity, which naturally made the emperor feel guilty.
After Qin Keqing's death, Jia Zhen held a funeral for Qin Keqing, which comforted the emperor's guilty heart to some extent. In order to reward Jia Fu, he promoted Yuan Chun, the daughter of Jia Fu, who worked as a female history in the palace, to several levels and was directly promoted to a virtuous princess.
How to prove that Yuan Chun's Golden Phoenix is related to Qin Keqing's funeral?
Evidence 1: When Qin Keqing gave her a dream after Xifeng's death, she not only asked her to plan the future, but also said, "There is another very happy event recently, which is really complete and full of flowers." As we know, this "happy event" mentioned by Qin Keqing was to seal the princess in Yuan Chun. If the princess in Yuan Chun has nothing to do with Qin Keqing, why did the author make such an arrangement? Therefore, the reason why the author makes this arrangement is to tell readers that Qin Keqing's concubines are related to Qin Keqing.
Evidence 2: From the way relatives in Yuan Chun came home crying, we can know that her promotion was not because the emperor liked her. Judging from the situation of the Jia family at that time, its family had no real power, and the emperor's promotion was not out of netting the Jia family.
Conclusion: To sum up, Yuan Chun suddenly conferred the title of princess because the Jia family's handling of Qin Keqing's funeral was very agreeable to the emperor, so she took Jinfeng Yuan Chun as a reward for the Jia family. That's why Yuan Chun didn't bring any other substantial benefits to Jia Fu except adding a little fame to Jia Fu.
