Similarly, the sister died, the sister remarried, and the fate of Xiao Qin and Xiao Zou was completely different. The reason why one of them can be a proper wife, but the other can only be subordinated to the position of concubine, even if they have a commandment, they cannot turn over, which is determined by the status of the person they marry.
The reasons for Xiao Qin and Xiao Zou to marry into the husband's family are somewhat similar, both of them have the opportunity to marry their brother-in-law because their former brother-in-law felt guilty about his dead sister. However, Xiao Qin married Marquis Gu Lao, and Xiao Zou married Shen Guo's uncle, so that the treatment of the two people could not be the same.
The status of Marquis Gu was significantly lower than that of Shen Guo's uncle
The Gu family has military merit, and it can also be regarded as a large family in the capital, which is much higher than the status of the Earl's Palace where Mo Lan married. However, no matter how high the status of the Gu family is, in the end there is no royal blood, and there is no relationship with the royal family, in the final analysis, the old Marquis Gu is only a person who serves the royal family.

The marriage of large families only pays attention to the door-to-door pair, and there is no need for political marriage, so the choice is relatively free.
Old Marquis Gu was very willful in the choice of marriage partner, when he married the Great Qin clan, everyone felt that the Great Qin clan was not a good candidate to be a proper wife, she was frail and sickly, she could not manage the house, and there was no sense of marrying into the family at all.
But Gu Laohou was just like Gu Er in the future, he couldn't let go of his hand when he fell in love, and he married the Great Qin clan into the door regardless of his disregard.
Although the Gu family later committed a crime, the old Marquis Gu was forced to obey the family's arrangement, marry the Bai family, and fill the family vacancy with her dowry, but he only had the Great Qin Clan in mind. As soon as Bai Died, Old Marquis Gu could be free from family restraints, plus he wanted to find a woman who treated the children of the Great Qin Clan kindly, so he naturally chose the Little Qin Clan.
Since Old Marquis Gu wanted Xiao Qin to treat his children well, plus his position as his wife was indeed vacant, he needed to continue the string, and Xiao Qin became the gu family's eldest wife.
And Xiao Zou's marriage to Shen Guo's uncle, this status is completely different
In addition to being a human subject, Shen Guo's uncle was also an imperial prince. Empress Shen ascended the throne with the new emperor and belonged to the new nobles, but after the new nobles sat on the emperor's throne, the old-school nobles were bound to criticize. In this case, it is best to let the new and old nobles marry to balance the forces of all sides.
The new emperor already had an empress, and they asked the old nobles to send their daughters to the harem to become ordinary concubines, and they were afraid that they would not want to. The responsibility for this marriage had to be borne by the imperial relatives who were close to the new emperor. Uncle Shen Guo, who had just lost his wife, just met this condition.
Therefore, in order to balance the power of the imperial court, Empress Shen took the initiative to mate the daughter of the British Duke Zhang Shixu to Shen Guo's uncle, and directly continued to become a wife.
Originally, in that era, Shen Guo could still marry another peaceful wife, and Xiao Zou's marriage into the Shen family also came to the ping wife.
However, the British gong held a heavy army and regarded himself very highly, so that his daughter and Zou Shi, a young woman from Yuzhou, sat on an equal footing, and the British gong was the first not to agree.
In desperation, Xiao Zou's life only had to be a concubine.
In the final analysis, Shen Guo's uncle married Zhang for the country, and married Xiao Zou for love, so the arrangement of one wife and one concubine, both women have commandments in their bodies, which is originally the most balanced state.
Unfortunately, Xiao Zou does not know how to be content, blindly wants to be strong, and wants to fight for things that do not belong to him. She had a good life, but she had to live with Zhang Shi, and finally caused trouble in the back.
In fact, Xiao Zou could have avoided this fate of being a concubine, if Shen Guo's uncle wanted to marry her, Xiao Zou's refusal to bite to death would not be forced by Shen Guo's uncle. However, the personality difference between Xiao Zou and Da Zou is too big, Xiao Zou is bent on coveting wealth, so she married her former brother-in-law, and she does not know how to restrain her sharp edge, so she sent herself to a dead end.
