Why did Da Yuer end up?

In fact, she is not favored. You can look at her resume.

Bumu Butai was born on the eighth day of February in the forty-first year of Wanli (161March 12).

Ten years of destiny (1625), 13-year-old Bumu Butai married the eighth son of Nurhachi, Huang Taiji. In the eleventh year of the mandate of heaven (1626), Huang taiji inherited the Khan position.

In the third year of Tiancong (1629), Bumu Butai gave birth to a female Yatu, namely Princess Gulun Yongmu. Artu, the second daughter born in six years, is Princess Julun Shuhui, and the three daughters born in seven years are Princess Julun Duanxian.

In the first year of Chongde (1636), Huang Taiji was renamed Emperor, and Bumu Butai was named Princess of Yongfu Palace.

Chongde gave birth to Fu Lin, the ninth son of the emperor.

1629 gave birth to a girl, gave birth to this girl three years later, and gave birth to three more girls one year later. Great, although it's not a pet crown harem, it's almost the same, but in October of the eighth year of Tiancong, Bumu Butai's sister Hailanzhu married Huang Taiji and spoiled the crown harem. At this time, her status plummeted and she could only rank fifth. Huang taiji didn't like her very much from beginning to end. Her fortune-telling made her mother more expensive. I don't know if Dourgen has an affair with her, but it's better to make his son emperor than Hogg, at least it's easy to control.
