The Empress Wan-Rong (1906-1946), influenced by Western ideas on monogamy, clashed with Emperor Pu-Yi's second wife, the Imperial Concubine Wen-Xiu, who had suffered the Empress's insults for 9 years. The Emperor, however, favoured the Empress, and the Imperial Concubine remained a virgin. Eventually, Concubine Wen-Xiu fled the Palace, and the Emperor reluctantly agreed a divorce. Regarding it as a deep disgrace, Pu-Yi vented his anger onto the Empress, and refused to live with her. She gradually became addicted to opium, and later became pregnant by her bodyguard. The outraged Emperor ordered her baby killed at birth (thrown into a fireplace). The Empress went insane, so he shut her in the "Cold Palace" (actually a cruel prison). No one was allowed to visit her, not even her own brother. Soon, the Empress' health declined dramatically, she fully depended on opium. With the downfall of the Imperial Dynasty, Wan-Rong was kept in the prison alone painfully until she died.
