Born in Ba Commandery in Yi Province, an area shaped by Shu Han rule and frontier administration. Growing up amid wartime memories and local elites’ rivalries later sharpened his interest in records and reputation.

As a youth he studied Confucian classics and historical writing in the Chengdu-region intellectual milieu. Local teachers emphasized moral judgment in biography, training him to connect personal virtue with state fate.

He began official work under Shu Han, learning the practical routines of memorials, registers, and archival summaries. This administrative exposure gave him a working sense of how court documents could be turned into history.

In mid-career Shu assignments he handled paperwork and personnel assessments, where factional politics were constant. The experience taught him to write cautiously, weighing wording that could elevate or ruin a family’s standing.

Wei generals Deng Ai and Zhong Hui entered Shu, and Liu Shan surrendered, ending Shu Han. The shock of a fallen state impressed on him the urgency of preserving records before archives scattered or were rewritten by victors.

After the conquest, he navigated the shift from Shu institutions to the Northern-centered administration that soon became Western Jin. Serving new masters required political restraint while keeping faith with accurate documentation.

He gathered biographies, edicts, and regional accounts from Wei, Shu, and Wu circles, comparing conflicting versions. The work demanded careful cross-checking because many witnesses were partisan survivors of recent wars.

In Jin officialdom he encountered accusations that his judgments were either too harsh or too favorable, reflecting factional tensions. These controversies later colored how readers interpreted his praise and blame in historical biographies.

When Jin forces ended Eastern Wu, the Three Kingdoms period closed as a living political reality. The unification increased demand for an authoritative narrative explaining how competing courts rose, governed, and failed.

He shaped separate books for Wei, Shu, and Wu, using biography-centered chapters to present politics through individual careers. This format followed earlier models like Sima Qian and Ban Gu while adapting to recent documentation.

He synthesized archival records with private writings, weighing contradictions in dates, titles, and motives. The resulting portraits of figures like Cao Cao and Zhuge Liang balanced administrative achievements with moral interpretation.

He finalized the Sanguozhi, producing a concise but influential account of the era’s statesmen, generals, and institutions. Its tight prose and selective detail made it both readable and vulnerable to later criticism for omissions.

Copies of the Sanguozhi spread through educated circles, where readers compared it with regional memories and family traditions. Debate focused on whether his treatment of Shu and Wei reflected evidence, loyalty, or Jin political needs.

The Jin court entered a period of intense intrigue around imperial regency and powerful clans. In that climate, writing history was never neutral, and even earlier evaluations could be reinterpreted as factional weapons.

He gained recognition as the principal compiler of Three Kingdoms history, yet faced lingering allegations of partiality from competing regional perspectives. The disputes ensured his text remained central, constantly scrutinized by scholars.

He died with the Sanguozhi already established as a key historical reference for the recent past. Later commentators, especially Pei Songzhi, would expand and annotate his concise narrative, amplifying its long-term influence.
