Zhou's research can't be called sinology, and his achievements are mainly redology research. In fact, I think it is boring and sad for a person to study someone else's novel all his life, and it is also meaningful to write a famous book. As for Zhou's poetry and calligraphy, there is really nothing to point out. His poems are not so good, nor are his words. Better than the average person, of course. I've met Zhou, just an idle old man.
In contrast, Ji Xianlin won more than Joo Won?, and of course his cultural contribution was even greater.
