The Historical Clues Behind Chai Rong’s Path to Succession and the Brief Prosperity of Later Zhou

Chai Rong was not Guo Wei’s biological son, yet he became the heir to Later Zhou through their adoptive relationship, his long-standing loyalty, and his political and military abilities. His early death and the accession of a child ruler then caused Later Zhou’s power structure to quickly become unbalanced. Relevant surname and family materials still require careful examination against genealogies, historical texts, and local documents.

During the Five Dynasties period, political power changed hands frequently, and imperial succession did not always follow a father-to-son line. After Guo Wei, Emperor Taizu of Later Zhou, established the regime, he designated Chai Rong as his successor. This decision was related both to the political environment of the time and to the trust Chai Rong had earned over many years, as well as his abilities in governance and military command.

According to the surviving historical accounts, Guo Wei came into conflict with Emperor Yin of Later Han as a result of a coup in his early years, and his family members were implicated. The question of biological heirs thus became an important factor in Later Zhou’s succession arrangements. Chai Rong, meanwhile, entered Guo Wei’s household and political life at an early stage, sharing with him the experiences of military service and political upheaval. Although no directly verifiable biological father–son relationship necessarily existed between them, their adoptive relationship and long years together gradually made Chai Rong the person Guo Wei relied on most. Specific kinship ties, the circumstances of the adoption, and related family designations should still be verified through cross-reference with contemporaneous historical texts and reliable genealogies.

Chai Rong’s succession was not simply the result of Guo Wei’s personal choice. After Later Zhou was established, the regime needed a successor who could win the army’s trust while also handling fiscal affairs, official administration, and frontier defense. During Guo Wei’s rule, Chai Rong took part in state affairs and later ascended the throne as Emperor Shizong of Later Zhou. He implemented measures to reorganize the military and government, eliminate redundant and ineffective personnel, and restore production, while expanding Later Zhou’s influence through military campaigns against Southern Tang, Later Shu, and forces in the north. Historical assessments often regard him as one of the more capable rulers of the late Five Dynasties period, and his policies also created some of the conditions that later enabled Northern Song to complete the unification.

However, Later Zhou’s stability did not last long. When Chai Rong died, he was still relatively young, and his successor, Chai Zongxun, was still a child. Actual power at court therefore came to rest increasingly in the hands of senior generals and high ministers. The concentration of military and political power, the young ruler’s lack of the ability to govern independently, and factors including frontier deployments and the prestige of military commanders together produced Later Zhou’s fragile late-period situation. After the Chenqiao Mutiny, Zhao Kuangyin entered Kaifeng, and Chai Zongxun eventually abdicated, bringing the Later Zhou regime to an end. Historical accounts of the abdication process, the details of the edict, and the whereabouts of Chai Rong’s descendants are not entirely consistent across periods, so no definite conclusion can be drawn from a single narrative alone.

From the perspective of surname studies, discussion of Chai Rong and his descendants also involves the intersection of the historical memories associated with the Chai and Rong surnames. ZongMai’s surname materials have compiled the traditional commanderies of origin, hall names, and historical distribution of the Rong surname. However, sharing a surname does not mean sharing the same lineage, and a hall name alone cannot prove a direct connection between a particular branch and a historical figure. To investigate possible links among the descendants of the Chai surname, Chai Rong’s family, and people from a particular locality, researchers can compare genealogical lines and migration records in online family genealogies with family memoirs and local gazetteers, while carefully verifying the dates and transmission histories of genealogy prefaces, epitaphs, ancestral-hall inscriptions, and local documents. Research into one’s roots should also distinguish family legends and later attributions from original records capable of forming an evidentiary chain, avoiding the direct equating of cultural identity with conclusions about biological descent.
