Qu Fulan couldn't sit still for the whole night but eventually came to terms with it.
First of all, the evidence was insufficient. It's unrealistic to conclude she's not the original just because of some issues related to a purse.
A person's martial arts skills can change, so why can't sewing skills? She said her hand was injured and she couldn't hold a needle anymore, who could argue with that?
Even though her hand seems fine now, if a person's hand meridians are injured, it's true that they can't do many things; such situations are common even in modern times.
As for not recognizing the purse, that's even easier to explain, just brush it off with "past like smoke."
Since she's decided to forget everything and start anew, why recognize that purse at all? Not recognizing it is more logical.
Secondly, she is indeed the original, just with a different soul. As long as she doesn't say anything, who could see through appearances to the essence?
