Conclusion:Based on historical records and modern research, Li Chengqian's death was likely caused by multiple factors. The mental shock after the failure of the political struggle, the difficult conditions of exile, and possible chronic diseases all contributed to the premature death of the deposed prince. Historiographers in the Tang Dynasty were often vague about sensitive events out of political considerations, which also left a permanent mystery for later generations.
Extended thinking:Li Chengqian's tragedy reflects the cruelty of the ancient imperial succession system. As a prince with high hopes, his failure was not only his personal fate, but also the inevitable result of the operation of the power mechanism. Compared with the modern political system, this extreme personal dependence relationship has been replaced by institutional constraints, but the nature of the game in the transfer of power is still worth pondering.
