Who is Zhang Qiu's mother in Harry Potter and the Order of the Phoenix?

Certainly not ~ ~ The name of the female divination teacher is sibyll trelawney. There is no such relationship at all, just a mentoring relationship. We don't know whether Zhang Qiu has taken divination classes. If not, she might not have come into contact with Trelawney (if there is such a relationship, and it is in a school, Rowling's best writing style can't bypass the description), LZ, forget it ~ ~

Trelawney described in the book comes from a traditional magical family and has the ability to predict. Zhang Qiu didn't see this ability ~ ~ Moreover, Zhang Qiu described in the book is still a girl with oriental beauty, while Professor Trelawney is a little neurotic and strange. These two are complete strangers ~~LZ thinks too much ~ ~

I also want to know how LZ has such doubts.
