What is the relationship between Zhen Xuan and Sang Ni?

In Qiong Yao's drama Princess Pearl, there is a role that the audience can't ignore, and that is the gentle and lovely Princess Sunny. With her, no matter how much trouble the swallow caused, she could finally save the day. The main reason is that Galeries Lafayette especially likes Qing Er Gege.

And why Galeries Lafayette loves Qing Er Gege so much that he can watch several hit dramas. Princess Zhu Huan tells the story of the Qianlong period of the Qing Dynasty, and The Queen of the Palace tells the story of the Yongzheng period of the Qing Dynasty. In other words, the two plays are related in the historical background.

Zhen Xuan in Empress Entering the Palace is the Lafayette in Princess Zhu Huan, so she doesn't like Wei Zi, the daughter of Emperor Qianlong, which seems reasonable. After all, Gan Long is not her son, and Wei Zi is not her granddaughter.

But on the contrary, she likes Sang Ni so much. Does that mean Sang Ni is related to her? In this regard, many Zhen Xuan fans brainstormed and concluded that Sang Ni was Zhen Xuan's granddaughter.

At that time, in the biography of Zhen Huan, Zhen Xuan and Guo Jun Wang gave birth to a son and a daughter. The son's name is Hongzhan and the daughter's name is Linxi. Later, Hong Zhan was adopted to Guo Jun and Wang Mi, and he inherited the title at an early age. Hong Zhan in history is really true and was adopted to Prince Guo. However, Hong Zhong has nothing to do with "Zhen Xuan". He is the biological son of Qianfei.

Hong Zhan has a bad habit of being greedy for money. He occupied an important position at a young age, often encroaching on private land, expanding coal plants, selling illicit salt and buying and selling officials. All kinds of behaviors just hit the muzzle of Emperor Qianlong, so Emperor Qianlong reprimanded Hong Zhan in the hall, took his title and reduced him to Baylor. Unexpectedly, this incident hit Hong Zhan too hard. He could not afford to get sick and died of depression soon.

Hong Zhan left a daughter after his death, that is, Qinggege. When Zhen Xuan (Galeries Lafayette) learned about this, he immediately put her in the palace and took care of her in every possible way, even to the point of bidding.

Of course, this conjecture is not unreasonable. In Princess Pearl, once the swallow made a big mistake, and Sonny and Lafayette begged, "When I saw them, I thought of my origin." It was this sentence that successfully touched Galeries Lafayette and made her decisively agree to Sang Ni's request for intercession.
