They were under no obligation to assist Qiao Xuan.
Not only had they refrained from aiding Qiao Xuan, but they had also gone out of their way to curry favor with Third Lady and Qiao Wei. Particularly Qiao Kou, who acted as Qiao Wei's confidante and strategist, had provided Qiao Wei with numerous ideas to demean and belittle Qiao Xuan.

If Concubine Du were to actually take her own life in front of the Shao Family residence after being refused, it would undoubtedly trigger an outcry, potentially branding them as heartless and callous individuals.
In such a dire circumstance, no matter how innocent they might be, blame would inevitably fall upon them.
