In China's feudal ruling society, the most curious thing is whether the living of the emperors is as luxurious as the tv series. The diet of the ancient emperor did require many complicated steps to be presented to the emperor, but the more people who handled it, the greater the chance of the unscrupulous person to poison, but in history, very few emperors died because of eating poisonous food, Puyi said the real reason in his autobiography.

The emperor's meal, from cooking to putting on the table, needs to go through many links, and in the Qing Dynasty, the person in charge of the imperial dining room is the emperor's own family, so if you want to enjoy the glory and wealth for a lifetime, the person in charge of the meal is naturally very careful.
Each dish of the emperor from the purchase of ingredients, transportation, selection, washing, preparation, etc., each process has a person specially responsible, and when stir-frying a dish is taken care of by three people, supervising each other. After the problem, the three people naturally can't escape the interference, so no matter who uses the stone platform, it is very difficult to poison.
After cooking, there will be dozens of eunuchs lined up at the table, walking to the emperor's palace room in a mighty way, during which there will also be special eunuchs to supervise, even in the previous link, there will be special eunuchs to test the poison with silver needles when serving, and then there will be a special "trial eunuch".
If the eunuch had eaten it, there was no problem, the emperor would have started to move the chopsticks, and by the time of this series of steps, the meal would have been almost cold. Therefore, Puyi once wrote in his autobiography that although gui was an emperor, he never ate hot food in all these years.
In addition to these complicated palace rules, the Qing Dynasty also had a rule for the emperor called "eating vegetables but three spoons", that is, when the emperor eats, each dish can only be eaten three times at most, in case someone guesses that the emperor likes to poison in advance, so it can be seen that murdering the emperor through meals is a very difficult thing.
