Is biological, Zhu Qiyu is the son of Zhu Zhanji and Hu Shanxiang, and the second son of Zhu Zhanji. After Zhu Zhanji was defeated in the Battle of Civil Fort, Zhu Qiyu was promoted to emperor by ministers, and then Zhu Qiyu reigned for seven years, that is, he became emperor for seven years.

As the son of Hu Shanxiang, Zhu Qiyu has always been highly anticipated. Although Hu Shanxiang was a queen at that time, Sun became a queen because he always wanted her to be a queen, so after Hu Shanxiang was abolished, Sun became a queen.

Although the relationship between Hu Shanxiang and Zhu Zhanji is not good, there is no doubt that Zhu Qiyu is their son. Zhu Qiyu was not favored by Zhu Zhanji because of his mother Hu Shanxiang's behavior, so the father-son relationship between Zhu Zhanji and Zhu Qiyu was not good.

But in the end, Zhu Qiyu ascended the throne of the emperor. Although he was only in office for seven years, he was indeed the seventh emperor of the Ming Dynasty. Although the plot in the play is quite different from history, there is no doubt about the feelings with Sun.
