Du's three daughters are all queens, but their endings are different, mainly because this woman's marriage is a science, but she still has to rely on her own efforts to be invincible in her husband's family. Dugu Jialuo and her husband Emperor Wendi started the Sui Dynasty hand in hand, and Dugu Jialuo also became a concubine who ruled the Sui Dynasty with her husband. Although Dugu Prajna was the queen of the Northern Zhou Dynasty, her husband was a puppet emperor. At that time, Yuwen Hu was in charge of the court in the Northern Zhou Dynasty, so she was quite wronged as a queen, and Dugumanto had never been a queen before her death. However, her son Li Yuan founded the Tang Dynasty, and she was made a queen.

Du is arguably the best father-in-law in history. His three daughters all became queens, especially Dugujialuo. She and her husband, Emperor Wendi of Sui Dynasty, jointly founded the Great Sui Dynasty and unified the Central Plains. She is a great queen, and she is also a queen who scares the emperors. Although Wendi was the king of a country when she was alive, she did not dare to take sides with other women in the harem, even less did Sui. As long as he sees a harem woman, this woman will disappear the next day. This solitary galois not only holds the mother of a country, but also monopolizes the daughter of the emperor. It can be said that the ending is not only good, but also quite good.

Although she married Yuwen Hu, the emperor of the Zhou Dynasty, it was a pity that the actual ruler of the Zhou Dynasty was Yuwen Hu at that time, so her husband was a puppet emperor who didn't know how long he could live. Yu Wenhu killed the disobedient Yu Wenjue before making Yu Wenyu emperor, which shows how afraid Yu Wenyu is to sit down. This lonely Prajna queen naturally lived carefully, and finally she died alone.

Dugu Mantuo married the son of Li Hu, one of the eight pillars of the Western Wei Dynasty. Although the husband is mediocre, he and his wife love each other and have four sons and one daughter. She also leads an ordinary life. If her son Li Yuan hadn't started the Tang Dynasty, she would be an ordinary woman.
