Fifth and final of the Wu Di (Five Emperors) per the Shiji canonical-historical framework; foundational filial-piety exemplar of the Confucian-canonical tradition; son of Gusou ("Blind Old Man," mortal) and Wo Deng (mortal). Per Shiji, descended from Huangdi through Zhuanxu via several intermediate generations; the registry models his immediate parents Gusou and Wo Deng in parentIds, with the deeper Huangdi chain documented in notes. The Shun-stepfamily-abuse-and-filial-piety narrative — Shun continuing to honor and serve his father Gusou despite the multiple murder attempts orchestrated by Gusou, the stepmother, and the half-brother Xiang — became the foundational filial-piety case-study of the Confucian-Mencian tradition (Mencius 4A.28, 5A.1-4). The Yao-Shun-Yu abdication chain that completes with Shun's abdication to Yu the Great (the flood-controller minister) constitutes the foundational meritocratic-succession case-study of Confucian-canonical political theory: the throne is the gift of Heaven and the people based on virtue, not heritable property of the sovereign.
