Haizi and Gu Cheng are not poets of the same caliber.

Haizi possesses linguistic creativity and can forge a mirror world through language. His poetry contains a divine greater self and a transcendent tension that surpasses the human realm.

Gu Cheng is more like a child who never grew up, focused on his own acute sensibilities, yet lacking a sufficiently expansive love and gaze toward the world.

Haizi is a philosophical poet in the manner of Hölderlin, Rilke, and Li Bai, employing poetry as a medium for transcendent expression. Gu Cheng, placed in contemporary times, would be more of a literary youth level—possessing good lines, but lacking deeper profundity beyond that.
