So if there was a better choice, Old Madam Zhang and Zhang Xiaohui would abandon the Gu family without hesitation.
They had married Zhang Xiaohui to the Gu family because they saw that the Gu family's sons were rich and often sent good things back. Their own family had always been desperately poor, which was why they had chosen Gu Yunshen.
The exceptional times had not yet begun and landlords and background were not such a big deal. The Gu family had always been doctors and were fairly stable. So they allowed Zhang Xiaohui to marry Gu Yunshen.
