Old Madam Gu, indeed, after her daily prayers, would occasionally listen to the events concerning the mother and daughter as recounted by the Lady of the Gu Family, sometimes offering a few remarks.
The Lady of the Gu Family noticed that Old Madam Gu was interested, and during one of their rare conversations, she heard Old Madam Gu lament that if her lost daughter were still alive, she might now have children of her own, perhaps even grandchildren.
Seizing the opportunity, the Lady of the Gu Family asked, if one day they happened to find the lost sister, how could they confirm it? Over the years, Old Madam Gu had seen a few girls who had been vetted locally and might possibly be the lost sister, yet she would take one look and decisively declare them not.
The Lady of the Gu Family speculated that the sister might have a birthmark or something, otherwise, how could Old Madam Gu be so sure at a glance?
