Essentially, Young Master Ji was about the same age as the students in front of him, so there was no such thing as a generation gap. But apart from his age being roughly the same as the students in the classroom, in everything else—whether knowledge, insight, or social experience—he was many times richer than these peers sitting below the podium.
On top of that, even if he didn't say a word and just stood there on the platform, he was a walking, capital-letter "Handsome." Not to mention he spoke with humor and could quote ancient and modern, domestic and foreign; a clearly boring class was handled by him so that the atmosphere was great and the interaction was lively. The students were all unexpectedly active.
