Was Yongzheng stabbed to death by Lv Siniang?

13 Yongzheng years, outstanding achievements. However, while he was in power, he died suddenly. Yin Zhen died suddenly in Yuanmingyuan on August 23rd in the 13th year of Yongzheng (1735). According to Records of Sejong in the Qing Dynasty and Chronicle of Zhang, on August 20, the 13th year of Yongzheng, even though he violated the peace, he still listened to politics and summoned officials as usual. On 2 1 day, the illness worsened and the government was in power as usual. Zhang, a college student, visits every day and never stops. The emperor's four sons, Prince Li Hong, Prince Wu Zixu and Prince Hongzhou, waited on the imperial couch day and night. On the 22 nd, his condition deteriorated and he was over-rescued by doctors. On the 23rd, the medicine failed, and Yulong was a guest. Three days before and after, it can be considered as an emergency. Yin Zhen died suddenly, and the official book did not contain the reason. Therefore, for the mystery of Yin Zhen's death, the ruling and opposition parties have different opinions. Legend has it that Yin Zhen was stabbed to death by Lv Siniang. There are articles about Yongzheng's assassination in books such as Thirteen Dynasties of Qing Dynasty and Legacy of Qing Dynasty. Legend has it that Lv Siniang is the daughter of Lv Liuliang, and some people say that she is the granddaughter of Lv Liuliang. At that time, Lv Liuliang was executed or sent to the garrison because she was slaughtered in the literary inquisition after her death. However, Lv Siniang escaped with his mother and a servant, hiding in the crowd. Lv Siniang learned martial arts from his master, studied hard and practiced hard, especially fencing, and his skills were superb. Later, Lv Siniang disguised himself and entered the palace. One day, he took the opportunity to cut off Yongzheng's head. Or, Lv Siniang's master, a swordsman of Yongzheng, stayed to train female disciple Lv Siniang. This folklore has been circulating for more than 200 years. By 198 1, the underground palace of Yongzheng Tailing Palace had been excavated, but it was abandoned before it was built. But it is said that Yongzheng's coffin has been opened, and Yongzheng's body has no body, which proves that Yin Zhen's head was cut off by Lv Siniang. These legends are made out of nothing and are purely anecdotes of unofficial history. Scholars believe that in the case, the Lu family, men, women and children, have been strictly forbidden and cannot escape. Even the graves of father and son were monitored, and Lu was not spared. Therefore, Lv Siniang's statement about the assassination of Yongzheng is untrue and unreliable. Yong Zhengdi's death is a historical mystery.
