The queen mother married, Shunzhi became a monk, and Yongzheng succeeded to the throne were the three major historical doubts in the early Qing Dynasty. Over the past few hundred years, after the rendering of literati and ink artists, these three mysterious cases have become more and more mysterious. The three major mystery cases, especially the Queen Mother's marriage, are the most suspenseful, and after the interpretation of many TV series, this mystery case once became a hot topic of discussion among ordinary people.
So did Prince Rui Dolgon have a personal relationship with his fourth sister-in-law, the Empress Dowager Xiaozhuang? The answer is no. Even if there is some ambiguous relationship between them, it is just a false and unreasonable political method adopted by the Empress Dowager Xiaozhuang against the powerful Dolgon in order to preserve the throne of her son Emperor Shunzhi.
In the TV series "The Secret History of Xiaozhuang" filmed by Mr. You Xiaogang, in order to attract people's attention, he portrayed the Empress Dowager of Xiaozhuang and Dolgon as a pair of childhood sweethearts, and due to the intervention of Huang Taiji, the Empress Dowager of Xiaozhuang was forced to marry Huang Taiji. This story is inconsistent with historical facts, in fact, the Empress Dowager Xiaozhuang didn't know Dolgon at all before marrying Huang Taiji, let alone the so-called love between them.
Before the Manchus entered the customs, the relationship between men and women was very chaotic due to the little influence of Han culture. The legacy of the death of the father and the stepmother, and the legacy of marrying sisters-in-law and younger siblings can be seen everywhere. Taking Huang Taiji as an example, his concubine Empress Xiaoduanwen of Jin is Empress Xiaozhuang Wen and Concubine Chen's aunt, both of whom are from the Borzigit clan of the Horqin steppe.
When Huang Taiji was the four great beylers, his mother Meng Gugege had already passed away, and he was the eldest concubine Abahai who was succeeded by his father, Jin Dahan Nurhachi, and was very favored. This concubine gave birth to Nurhachi successively twelve sons Azig, fourteen sons Dorgon, and fifteenth sons Dordor. The three young sons, especially Dorgon and Dord, were loved by their father, and they were given the position of banner lord by Nurhachi at a young age.
In his early years, Nurhachi had his eldest son Chu Ying as his heir, and due to Chu Ying's own reasons, since Chu Ying was deposed, he took the Great Belle as his heir. But this Daishan and the concubine frowned, because of this reason, Nurhachi did not designate ** people during his lifetime.
In this case, because the Great Bel was well snubbed, the second Bel Amin was a nephew, and the third Bel had a stabbing mother, so that the heirs to the Khan throne of Nurhachi a hundred years later were only Huang Taiji, Dolgon, and Duoduo. If Nurhachi lived for two more years, with the relationship between the concubine and the re-favored relationship, Dolgon and Duoduo would definitely have a greater chance of ascending to the throne than Huang Taiji. 
Nurhachi's attack on Ning Yuan was at a loss, and he rarely lost a battle in his life, and his psychological trauma was greater than skin trauma. Before he died, he specially summoned the eldest concubine to ask for the future, because Dolgon was only fifteen years old this year, and as a result, he was the first to ascend by Huang Taiji, he not only robbed the throne of the Khan, but also united with other great Baylors to force the concubine to death.
Although Huang Taiji did not kill the three younger brothers born to the eldest concubine, and still raised and nurtured them, how could the hatred of killing his mother be forgotten because of his kindness. This is also the main reason why Dolgon has a love-hate relationship with Huang Taiji in the future.
During the seventeenth year of Huang Taiji's reign, Dolgon and his brothers made many miraculous contributions to the final establishment of the Qing Dynasty under his training, and they were also named the King of Dorowuying, Prince Rui, and Prince Yu for their merits.
After the death of Huang Taiji, Dolgon and his brothers once united with the two white flag soldiers to try to regain the throne that he thought belonged to him, but due to the strong opposition of the two yellow flag soldiers, Prince Dai Shan and Prince Zheng Zilharang did not make a statement, and Dolgon had no choice but to set up Huang Taiji's six-year-old son Fulin as the emperor, and he was the co-adjudicator of Prince Zheng Zierharang as his uncle regent.
With the Qing army entering the Central Plains, Dolgon's identity was gradually promoted from his uncle regent to his uncle regent and then to his father's regent, and he was only one step away from the emperor at this time. If the day is a holiday, the history of whether he usurps the throne or not cannot be assumed.
It is precisely because of Dolgon's great power, in order to keep the throne of his son Fulin, the Empress Dowager Xiaozhuang will inevitably show favor to him to consolidate his loyalty, and Dolgon once robbed Prince Su Haoge Fujin as his wife, so the descendants thought that the Empress Dowager Xiaozhuang had something to do with Dolgon.
