Unveiling Wu Zetian's Zhì Yù: The Bloody Cage Under Lijing Gate

Brief Introduction

"Zhì Yù" (Imperial Prison) was a special prison established by Wu Zetian before and after her ascension to the throne, located within Lijing Gate in the Divine Capital, Luoyang. Unlike ordinary judicial institutions, it served imperial power directly, used to detain political prisoners, members of the royal family, and opposing officials. As the core venue of tyrannical politics, Zhì Yù witnessed the most bloody political purges during the Zhou period, serving as a key window for understanding Wu Zetian's ruling methods.

Core Knowledge Points

* Location and Naming: Located inside Lijing Gate in Luoyang. It was named "Zhì Yù" because it was controlled directly by imperial edict (Zhì), bypassing the Three Judicial Offices (Dali Temple, Ministry of Justice, and Censorate).
* Management by Cruel Officials: Primarily managed by tyrannical officials such as Lai Junchen, Zhou Xing, and Suo Yuanli. They created numerous torture devices, such as the "Dead Pig Trough" and "Suddenly Roar," aimed at extracting confessions through extremely cruel means.
* Political Function: Mainly used to strike at the Li Tang royal clan and former officials. By creating an atmosphere of terror, it consolidated Wu Zetian's rule and cleared obstacles to her ascension, particularly targeting forces opposed to changing the dynasty from Tang to Zhou.
* High Mortality Rate: According to historical records, nine out of ten detainees died here, with few surviving to leave. It became a nightmare in the hearts of officials.

Connection with "Zizhi Tongjian"

Sima Guang recorded the rise and fall of Zhì Yù in detail in the Zizhi Tongjian: Tang Annals. The book not only describes the cruelty of the prison but also examines it within the broader context of Wu Zetian's consolidation of power. By recording Lai Junchen's actions within Zhì Yù, Sima Guang reveals the destruction of court order caused by tyrannical politics.

In the narrative of the Zizhi Tongjian, Zhì Yù was not merely a physical space but a political barometer. When Wu Zetian needed to strike at dissidents, the prison unleashed slaughter; when she realized that tyrannical officials threatened imperial power, she abandoned them. The book records stories of officials like Di Renjie surviving death within Zhì Yù, showcasing the survival wisdom of officials at the time and the game of power with the emperor. Although Sima Guang did not directly comment on this, his detailed records convey a critique of arbitrary punishment, reflecting the historian's original intention of "aiding governance."

Conclusion

Zhì Yù is a unique historical symbol of the Wu Zetian era. It is both an extreme manifestation of imperial autocracy and an important case for reflecting on the rule of law versus tyranny in the Zizhi Tongjian. Through this historical detail, we can more deeply understand the political ecology of the Zhou period and the historical lessons brought by the loss of control over power.
