Bruce's words indeed made Lu Xuanyu start to think.
"Rich literature, poor martial arts" is not just reflected in this minor aspect of "diet."
The ultimate pursuit of literature, all experiences, can be documented in words. Without this, it doesn't count as establishing a school of thought through writing and naturally can't be called literature. However, the supreme realm of martial arts often defies description in words, and martial masters may not know how to describe their experiences—it's outside their professional range.
Information from literature has a very low cost to reproduce—just books. With the advent of e-books, the cost is nearly zero. But the martial artist's experience is still best taught face-to-face.
