There are many educators who truly consider the students' interests, and Principal Li Nanxing is a prime example. He doesn't take credit for others' work, nor does he attribute Xiang Beifei's achievements to himself. On the contrary, he generously admits his misjudgment and conducts himself with openness.
His "Confucian Saint System" gains prestige through genuinely cultivating students, and Xiang Beifei greatly respects such a teacher and senior. He wishes for more educators like Principal Li Nanxing in the world, so that more students can benefit.
If he could help Principal Li Nanxing gain more prestige, Xiang Beifei would be happy to do so.
The teachers of Xiang Beifei's other subjects are also acceptable; they don't intentionally trouble the students or belittle and mock them.
However, in any profession, there will always be some rotten apples like Yang Hua.
But this doesn't matter, for the kind are always treated with kindness, and the deceivers are always abandoned.
