Because of a young person's urge to show off, Qiao Yu initially considered sending a copy to Professor Zhang Shuwen at Princeton as well.
But after some thought, he decided against it. Although he was quite confident, it was his first time tackling such a major thesis topic, and since he had completed it entirely on his own, he wasn't sure if his final result would gain recognition.
Better to let his advisor and academic grandfather review it first.
In case there were any major issues, he would have a chance to amend them. If Professor Zhang were to point out any significant problems, he'd end up being scolded by an outsider for no reason.
Hmm, being reprimanded by one's mentor could still strengthen their bond, but being lectured by an outsider, even if it's for your own good, would just feel stifling.
