Stick to the facts.
The responsibility for the situation as it stands today isn't entirely on Gu Changsheng...
Even if Gu Changsheng hadn't provoked Xie Chong the day before yesterday, Xie Chong would definitely not have let it go after investigating Gu's academic records. After all, this was a golden opportunity to bring down Mr. Han Taiqing, an opportunity not to be missed.
And as for Mr. Han Taiqing...
He was well aware of Gu Changsheng's situation from the start, yet he still insisted on hiring him to teach.
On the one hand, he valued Gu Changsheng's abilities, and on the other, he chose to overlook the issue of qualifications and experience, leading to all that's happened.
As everyone has seen...
The person was brought in by Mr. Han Taiqing, so he must take full responsibility.
