What if she teach a family of paper artisan tricks on how to do better?!
She was the student of a doctor who went to the west to gain knowledge, so ofc she knews more tricks that that family who never leaved town !
Also you may feel that all what is happening is irrelevant to the main plot , but from my experience of reading the novel, i can tell you that everything that happen is a peice of puzzle to complet the finale mystery in the arc 😊
