Task: Question Generation
Input (English): Context_1 : Empress Dowager Dong (died 189), personal name unknown, formally known as Empress Xiaoren, was an empress dowager of the Eastern Han dynasty. She was never empress throughout her life because she was the wife of a marquis; she only became empress dowager because her son, Liu Hong (Emperor Ling), became the emperor by chance. During her son's reign, she developed a rivalry with her daughter-in-law, Empress He, because she wanted Emperor Ling's younger son, Liu Xie, to be crown prince while Empress He wanted her own son, Liu Bian to succeed his father. Emperor Ling died in 189 before he managed to designate either of his two sons as crown prince. Liu Bian eventually took the throne as Emperor Shao; Empress Dowager Dong, as the emperor's grandmother, became grand empress dowager, while her daughter-in-law became empress dowager. Empress Dowager He eventually conspired with her brother, General-in-Chief He Jin, to unseat her mother-in-law from power. Grand Empress Dowager Dong died of illness shortly after her downfall; the common people held Empress Dowager He and her family responsible for the grand empress dowager's death. Context_2 : Zhangsun Wuji (died 659), courtesy name Fuji, formally the Duke of Zhao (趙公 ), was a Chinese official who served as a chancellor in the early Tang dynasty. He was Empress Zhangsun's brother, which made him a brother-in-law of Emperor Taizong (Li Shimin) and a maternal uncle of Emperor Gaozong (Li Zhi). He was an important advisor to Li Shimin when the latter was still the Prince of Qin during the reign of his father, Emperor Gaozu. He helped Li Shimin overcome his brothers Li Jiancheng (the Crown Prince) and Li Yuanji (the Prince of Qi) in a succession struggle at the Xuanwu Gate Incident, eventually enabling Li Shimin to become the heir apparent and later the emperor. He was also instrumental in Emperor Taizong's selection of Li Zhi as the Crown Prince, and was exceedingly powerful after Li Zhi took the throne as Emperor Gaozong. However, he gradually fell out of his nephew's favour by failing to support Emperor Gaozong's decision to depose his first wife, Empress Wang, and replacing her with Empress Wu. In 659, Zhangsun Wuji was falsely accused of treason by Empress Wu's political ally, Xu Jingzong, and eventually ordered to be sent into exile by Emperor Gaozong. Xu Jingzong subsequently sent the official Yuan Gongyu (袁公瑜) to force Zhangsun Wuji to commit suicide on his way to exile. Context_3 : Li Chongjun (李重俊) (died 7 August 707), formally Crown Prince Jiemin (節愍太子), was a crown prince of the Chinese dynasty Tang Dynasty, during the second reign of his father Emperor Zhongzong. He was made crown prince because the only son of his father's wife Empress Wei, Li Chongrun, had been killed before his father's return to the throne, but on account of his mother's low birth, he was often humiliated by Empress Wei's daughter Li Guo'er the Princess Anle and her husband Wu Chongxun (武崇訓). In 707, in anger, he started a coup and killed Wu Chongxun and his father Wu Sansi the Prince of Dejing, but his subsequent attempt to arrest Empress Wei, Li Guo'er, and Consort Shangguan Wan'er was thwarted, and he was killed in flight.

After Empress Wang was displaced by Empress Wu (later known as Wu Zetian) in 655, however, Li Zhong was caught in Empress Wu's crosshairs and was forced to yield the crown prince position to his younger brother Li Hong, born of Empress Wu, in 656. He was later further reduced to commoner rank and put under house arrest, and when the chancellor Shangguan Yi failed in his attempt to persuade Emperor Gaozong to depose Empress Wu in 664 and was executed, Empress Wu took the opportunity to accuse Li Zhong of being complicit in Shangguan's plans.
