Po Jun is the eighth and final star of the Tian Fu series, its chart position fixed at a set offset from Tian Fu's own calculated palace, closing an order that runs Tian Fu, Tai Yin, Tan Lang, Ju Men, Tian Xiang, Tian Liang and Qi Sha before it, the series' most forceful and disruptive stars, Qi Sha and Po Jun, both positioned at its very end.
Read together with Lian Zhen, the volatile closing star of the six member Zi Wei series, Po Jun means that both of the system's two founding star series end on their most difficult, double edged member rather than on a settled or straightforwardly favourable note, a pattern Ho Peng Yoke's account of the system does not connect to any stated design principle but which later practitioners within the tradition have found a suggestive symmetry regardless.
Po Jun's presence in a chart's Career Palace specifically is read by the tradition as favouring careers built on genuine disruption and reinvention, entrepreneurship, radical reform, the arts at their most experimental, fields where breaking an existing order is precisely the value being offered rather than a cost to be managed, the star's destructive reputation finding its most legitimate and rewarded expression in exactly that kind of work.
