Chinese celestial goddess; sister of the Jade Emperor; mother of Erlang Shen by the mortal scholar Yang Tianyou. The Investiture-of-the-Gods stratum makes her the divine sister-aunt of the Heavenly Court; older Song Yu strata (3rd c. BCE Gaotang Fu) place her as the Wushan Goddess of the Yangtze gorges. Late Bao Lian Deng accretion identifies her as governing the realm of desire — the conceptual frame motivating her descent. Imprisoned beneath Mount Tao by the Jade Emperor; freed by Erlang Shen's axe-cleaving rescue.
