Faruzan Genshin Impact

There is a legend among the students of Kshahrevar:
If you've failed your mechanics exams and are hesitant to ask your disgruntled mentor for a couple of extra lessons to remedy the situation, you can head to nearby Harawatat and ask Madame Faruzan for advice.
You don't have to bring a gift. Just remember to be sincere and humble, and address her with respect as "madam." This will be enough to achieve the location of a living encyclopedia of mechanics.
Madame Faruzan's explanations are clear and at the same time thorough, and her profound knowledge makes one wonder if she had a hand in the curriculum. Her instructions will help solve the most difficult problems, but still there are two problems that all students must solve on their own.
The first is how to hide your surprise at meeting her and not be confused by her youthful appearance.
The second is to refrain from asking why she is shunned in Haravatat despite her outstanding erudition, and whether she should consider moving to Kshahrewar.
If you have the misfortune to commit even one of these mistakes, you will witness rhetoric worthy of the biggest name in Haravatata, especially when it comes to criticizing and blaming others.

“Much of the material presented in this book comes from the theories and writings of Madame Faruzan. We hope that future generations of scientists will remember her name when she returns to the Academy.". – Quote from the book “Introduction to Ancient Machines”. This text was published almost a hundred years ago and is still included in the list of required reading in the darshan of Kshahrevar.
