Xu Zichun is from Yunnan Province surrounded by mountains located in the heart of mainland China.

Xu, who gets inspiration from music and memory, derives the flow of time from the flow of musical scales. He depicts the mountains and horizon of his hometown, showing that matter goes through various intonations and adjusts to neutrality, just like a musical scale that repeats highs and lows and then adjusts to "♮" (natural). This evokes the formal elements of "poem," which unfolds with a structure of introduction, development, turn, and conclusion.
