There are also some chronic poisons. If the dose is very light, it is impossible to test the poison with a silver needle. There will be no changes in the body in the short term, and signs of poisoning will gradually appear after a long time. If the eunuch's maid-in-waiting finds out which dish the emperor likes to eat, she poisons it.
Therefore, in order to ensure the safety of the dragon body, the best way is not to let everyone know what the emperor likes to eat. You only eat two servings of each dish, so the probability of successful poisoning is relatively low. The emperor can't poison every meal with dozens of dishes!
Xuantong, the last emperor, protested that he could not eat more than three dishes. He was too humble to live. The eunuch told him that this is a rule left by his ancestors and must not be broken.
When eating the third bite, the serving eunuch will give a hint. If you eat the third bite, not only will this dish be taken off the shelf, but it will not be served for ten and a half days! If the emperor doesn't want to eat this dish in the next half month, he can only eat two bites and stop.
Dozens of dishes in a meal, one dish 1-2, you have to eat enough! What should the emperor do with the leftovers? Dump it all? Wouldn't that be a waste? How to dispose of the remaining dishes, the requirements of each dynasty are different. Some are for ladies-in-waiting and eunuchs. These foods have only been eaten once or twice. It would be a pity to take them down.
Some of them are even sold outside the palace, because the dishes eaten by the emperor are all delicacies, which are specially made for the emperor by the royal chef. In order to taste the food eaten by the emperor, people will scramble to buy it.
