Kou Voravong
The political crisis caused by his assassination, barely two months after the Geneva Agreements which prepared to restore peace in Indochina, contributed to bring down the current neutralist government (pro-French) which was replaced by a progressive one (pro-American) in extremely tense atmosphere of the Cold War between Russia and the United States. From 1955 indeed, the political history of this small landlocked country fell trapped inexorably in the ideological confrontation between the capitalist United States and the communist Soviet Union, annihilating any hope of national unification.
Kou Zhu
In the 19th-century novel "The Seven Heroes and Five Gallants", she is credited with saving the newborn Emperor Renzong: when her master Concubine Liu ordered her to strangle him and dump his body under a bridge, she gave the infant to the eunuch Chen Lin instead. Years later, she was tortured by Liu (then already the empress thanks to her conspiracy) and her eunuch Guo Huai, and committed suicide. Still years later, Bao Zheng and his chief strategist Gongsun Ce "invoked her ghost" to extract a confession out of Guo.
