The first argument is the official "theory of normal death" in Qing Dynasty. In Zhu Shoupeng's "Guangxu Chaodong Lu Hua", Ci 'an's testamentary edict is contained, saying that she occasionally contracted boils on the ninth day of the ninth lunar month (188 1) and was seriously ill on the tenth day of the tenth lunar month. After a long delay, her thoughts gradually dispersed and she died. But this "death" came so quickly and suddenly that even the parties at that time were greatly suspicious. According to Qing Chao, Ci 'an felt unwell at first, and the physician Xue felt his pulse quickly, thinking that "there is no need to take medicine for minor ailments". Unexpectedly, I was greatly surprised to hear that "Dongke has handed over the coffin" that night, and even spread to the outside world. Later, the bad news confirmed that he said with great sorrow: "This happened between heaven and earth. Can I still be here? " I don't believe that Cian died of illness. Another party, Zuo, then minister of military affairs, suddenly heard that Ci 'an was ill and died, and stamped his foot and said loudly, "Yesterday morning, it was clear and clear, just like a patient. "Even if you get sick, how can it be so fast?" The second theory is that Ci and Ci 'an made bad friends and Ci 'an was forced to commit suicide. According to "Qing Chao", Ci 'an and Cixi listened to politics, and Cixi had a strong desire for power, but Ci 'an was tired of doing things and did not fight for power, so she enjoyed it. However, at the beginning of 188 1, Cixi suffered a bloody drama, so she couldn't take care of things. There was a time when Ci 'an only looked at state affairs, which made Cixi very unhappy. "She intervened in state affairs by bribing and selling entrustment, and her words were quite radical." As a result, Cian was very angry, and she couldn't refute it. In a rage, she "swallowed her snuff bottle." The third argument is that Cixi poisoned herself with drugs. According to "The Waiji of Cixi", when Xianfeng died, he secretly left a testament to Ci 'an, asking her to supervise Cixi. If Cixi "keeps her position, that's enough, otherwise you can issue this imperial edict and order the courtiers to pass on the inheritance." But honest Cian told this story to Cixi. Hearing this, the sinister and diabolical Cixi apparently wept for Ci 'an. In fact, she had already killed her, so she took the opportunity to offer bait to Ci 'an, secretly poisoned it and murdered it. Another Wen Tingyun's "Smell the Wind and Dust" thinks that Cixi was pregnant because of adultery and was discovered by Ci 'an, and is going to abolish the title of Empress Dowager Cixi. As soon as Cixi heard this, she moved her hand first and poisoned Ci 'an. In the palace, it is an eternal mystery. The latter statements are all hearsay and unofficial history's notes, and there is no reliable historical basis. What the truth is, it needs further research and analysis. However, in Sui's Cixi, she said that Ci 'an died of a normal disease. Death of Empress Ci 'an 1860 In August, Emperor Xianfeng died in Jehol, and his 6-year-old son Zai Chun succeeded him, while Empress Ci 'an and Empress Dowager Cixi listened to politics. Emperor Xianfeng had long known that Cixi was an ambitious woman. So before he died, he sent a secret letter to Empress Cian, asking Cian to take out the secret letter and punish her according to the rule of law in his ancestors. After Xianfeng's death, Cian showed the secret letter to Cixi as a warning. Cixi was shocked and uneasy by the existence of the secret edict. She was cautious and did not dare to run amok. She is obedient and meticulous to Ci 'an. After a long time, when Ci 'an saw that Cixi had held the place, he put down his guard. One day, Ci 'an fell ill and took too many medicines prescribed by doctors, which had no effect. In a rage, Cian refused to take medicine. Unexpectedly, a few days later, her illness miraculously recovered. After recovering from a serious illness, Ci 'an happily went for a walk in the Summer Palace, only to find that Cixi's left arm was wrapped in white gauze. She was surprised and asked Cixi why. Cixi casually replied: "The other day, I saw you lying in bed, pale and sad, so I cut a piece of meat from my left arm and asked someone to cook soup to nourish you to show my sincerity." Hearing this, Ci 'an was greatly moved and said gratefully, "I didn't expect you to be such a kind person. The first emperor shouldn't worry about you. " After that, he returned to the palace, took out the last secret letter of Emperor Xianfeng and burned it to ashes in front of Cixi. Without the tip-off, a stone hanging from Cixi's heart fell to the ground, and she felt much more relaxed, because there was nothing to be afraid of anymore. As soon as she changed her normal state, she began to speak ill of Ci 'an, and she was no longer as respectful to Ci 'an as before. She monopolizes political affairs in North Korea, big and small, and doesn't care about Ci 'an at all. Cian knew he had been cheated. He complained bitterly, but it was too late to regret it. Later, in order to get rid of Ci 'an, a stumbling block on her autocratic road, Cixi secretly ordered the use of too many drugs, which killed Ci 'an. Since then, Cixi, a sinister and diabolical woman, has ascended the throne of the supreme ruler of the Qing Dynasty and realized her dream.
