According to Records of Sejong in Qing Dynasty and Chronicle of Zhang, on August 20, the 13th year of Yongzheng, Yongzheng occasionally felt disobedient, and 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 great scholar, never stops visiting him every day. The fourth son of the emperor, Prince Li Hong and Prince Hongzhou, etc. All stood on the side of the collapse of the empire and served 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. But official records are sometimes tampered with by the emperor.

Others are recorded by unofficial history.

In the absence of conclusive evidence, the official records shall prevail.
