A poem expresses aspirations in one's heart. Zhi (志) here means the author's

aspirations, emotions, and thoughts. The concept of "poetry expressing

aspirations," first seen in the Confucian classic The Book of History, was hailed

by Zhu Ziqing as the "manifesto" of Chinese poetry. Enriched by poetry critics

through the generations, it was later established as a basic concept in Chinese

literary criticism.
