His and Zhu Rong's teaching philosophies are opposite; he leans towards practicality, or perhaps a cold-blooded approach.
He wants the students to recognize the world's cold-hearted nature while still at the academy so that after graduation, they can quickly adapt to society and understand the true essence of how the world operates.
On the other hand, Zhu Rong leans towards idealism, or one might say a warm-hearted approach.
In his philosophy, the academy is the last haven of warmth in this cold-hearted world. Cold-blooded teaching methods can push students to extremes, turning them into mere killing machines.
He wants to preserve the students' warmth and let them spread this warmth.

As humans, we should possess humanity.
