Peng Zixu is one of Zhou Songyan’s close friends from the capital circle. He appears during a gathering with Qin Xuan, noting that Zhou Songyan has been acting unsettled. He teases Zhou about being “unsatisfied” and brings up Guan Qing, suggesting she might be the source of Zhou’s distraction. Peng Zixu is perceptive about his friend’s mood but lacks deep insight. He is part of Zhou’s social environment, providing a glimpse into Zhou’s private life and past. His casual mention of Guan Qing hints at a complicated romantic history. He represents the wealthy, idle peer group that surrounds the young master.
