What poem did Ye Xie write to promote his poetic ideal during his study tour?

During his study tour, Ye Xie was very dissatisfied with the rigid imitation and retro style prevailing in the poetry circle at that time. In order to publicize his poetic ideal, after returning to Hengshan, Ye Xie began to recruit students, set up a museum for his disciples, systematically teach his own poetic views, explain poetry theory and guide poetry creation. At the same time, in addition to teaching, he also wrote a book about poetry, The Original Poetry.
