Before dying, Li explained that Cixi did not die of natural causes, but was poisoned. According to historical records, Empress Dowager Cixi got dysentery when she was old, and finally died because of ineffective treatment. In fact, dysentery is what we now call gastroenteritis. It can cause unbearable stomach pain when it comes on, but it won't kill you. If someone hadn't found Li and later found out the facts, it is estimated that outsiders can't know the real cause of death of Cixi.

We are all familiar with Cixi. She was in charge of the political power in the late Qing Dynasty, and eunuch Li was her most trusted person. According to historical records, Li was deeply loved by Cixi at that time, because he had a unique skill, namely ventriloquism and massage, which could relieve Cixi's boredom, and massage could relax muscles and promote blood circulation. He used these two techniques to coax Cixi to be very happy. At that time, it was even said in the palace that he would rather offend the emperor than Li, which shows how much he was favored in front of Cixi.

When Eight-Nation Alliance attacked, Li fled the capital with Emperor Guangxu and Cixi, and the Qing Dynasty soon perished. Li lived incognito in a country, because he had served Cixi, but because he was a red man in front of Cixi, many people were asking about his whereabouts. In fact, they just wanted to know the secrets of the royal family from him.

When Li is old, he is still found by them. At this time, he is no longer afraid to ask any questions and will answer them truthfully. When asked about the scene of Cixi's death, Li told Cixi that she died of poisoning. According to him, Cixi died of chronic poisoning instead of acute toxicity. This medicine will not kill people immediately, but will slowly damage the internal organs and eventually lead to death.
